11:00 Systems Pharmacology in a Post-Genomic Era

Peter Sorger, Ph.D., Professor, Systems Biology, Harvard Medical School; Co-Chair, Harvard Initiative in Systems Pharmacology

I will describe the emergence of “systems pharmacology” as a means to guide the creation of new molecular matter, study cellular networks and their perturbation by drugs, understand pharmaco-kinetics and pharmaco-dynamics in mouse and man and design and analyze clinical trial data. The approach combines mathematical modeling with empirical measurement as a means to tackle basic and clinical problems in pharmacology. Ultimately we aim for models that describe drug responses at multiple temporal and physical scales from molecular mechanism to whole-organism physiology.

11:30 Using Quantitative Systems Pharmacology for De-Risking Projects in CNS R&D

Hugo Geerts, Ph.D., CSO, Computational Neuropharmacology, In Silico Biosciences

Quantitative Systems Pharmacology is a computer based mechanistic modeling approach combining physiology, the functional imaging of genetics with the pharmacology of drug-receptor interaction and parameterized with clinical data and is a possible powerful tool for improving the success rate of CNS R&D projects. The presentation will include failure analyses of unsuccessful clinical trials, correct prospective identification of clinical problems that halted clinical development and estimation of genotype effects on the pharmacodynamics of candidate drugs.

HIGH CONTENT ANALYSIS: CANCER CELL LINES

1:40 Chairperson’s Remarks

1:45 Systems Pharmacology Using CellMiner and the NCI-60 Cancerous Cell Lines

William Reinhold, Manager, Genomics and Bioinformatics Group, Laboratory of Molecular Pharmacology (LMP), National Cancer Institute (NCI)

CellMiner is a web-based application that allows rapid access to and comparison between 20,503 compound activities and the expression levels of 26,065 genes and 360 microRNAs. Included are 102 FDA-approved drugs as well as 53 in clinical trials. The tool is designed for the non-informatisist, and allows the user wide latitude in defining the question of interest. This opens the door to systems pharmacological studies for physicians, molecular biologists and others without bioinformatics expertise.

2:15 Oncology Drug Combinations at Novartis

Joseph Lehár, Ph.D., Associate Director, Bioinformatics, Oncology Translational Research, Novartis; Adjunct Assistant Professor, Bioinformatics, Boston University

Novartis is undertaking a large-scale effort to comprehensively describe cancer through the lens of cell cultures and tissue samples.  In collaboration with academic and industrial partners, we have generated mutation status, gene copy number, and gene expression data for a library of 1,000 cancer cell lines, representing most cancer lineages and common genetic backgrounds.  Most of these cell lines have been tested for chemosensitivity against ~1,200 cancer-relevant compounds, and we are systematically exploring drug combinations for synergy against ~100 prioritized CCLE lines.  We expect this large-scale campaign to enable efficient patient selection for clinical trials on existing cancer drugs, reveal many therapeutically promising drug synergies or anti-resistance combinations, and provide unprecedented detail on functional interactions between cancer signaling pathways.   I will discuss early highlights of this work and describe our plans to make use of this resource.

3:45 Systems Biology in Cancer Immunotherapy: Applications in the Understanding of Mechanism of Action and Therapeutic Response

Debraj Guha Thakurta, Ph.D., Senior Scientist II & Group Leader, Systems Biology, Dendreon Corporation

We are using high-content platforms (DNA and protein microarrays, RNA-seq) in various stages of the development of cellular immunotherapies for cancer. We will provide examples of genomic applications that can aid in the mechanistic understanding and the discovery of molecular markers associated with the efficacy of a cancer immunotherapy..

4:15 Use of Systems Pharmacology to Aid Cancer Clinical Development

Anna Georgieva Kondic, Ph.D., MBA, Senior Principal Scientist, Modeling and Simulation, Merck Research Labs

The last few years have seen an increased use of physiologically-based pharmacokinetics and pharmacodynamics models in Oncology drug development. This is partially due to an improved mechanistic understanding of disease drivers and the collection of better patient-level quantitative data that lends itself to modeling. In this talk, a suite of studies where systems modeling was successfully used to inform either preclinical to clinical transition or clinical study design will be presented. The talk will complete with a potential systems pharmacology framework that can be used systematically in drug development.

MODELING AND MINING TARGETS

8:45 Chairperson’s Opening Remarks

8:50 Systems Biology Approach for Identification of New Targets and Biomarkers

I-Ming Wang, Ph.D., Associate Scientific Director, Research Solutions and Bioinformatics, Informatics and Analysis, Merck Research Laboratory

A representative gene signature was identified by an integrated analysis of expression data in twelve rodent inflammatory models/tissues. This “inflammatome” signature is highly enriched in known drug target genes and is significantly overlapped with macrophage-enriched metabolic networks (MEMN) reported previously. A large proportion of genes in this signature are tightly connected in several tissue-specific Bayesian networks built from multiple mouse F2 crosses and human tissue cohorts; furthermore, these tissue networks are very significantly overlapped. This indicates that variable expression in this set of co-regulated genes is the main driver of many disease states. Disease-specific gene sets with the potential of being utilized as biomarkers were also identified with the approach we applied. The identification of this “inflammatome” gene signature extends the coverage of MEMN beyond adipose and liver in the metabolic disease to multiple diseases involving various affected tissues.

9:20 Optimizing Therapeutic Index (TI) by Exploring Co-Dependencies of Target and Therapeutic Properties

Madhu Natarajan, Ph.D., Associate Director, Computational Biology, Discovery Research, Shire HGT

Conventional drug-discovery informatics workflows employ combinations of mechanistic/probabilistic in-silico methods to rank lists of targets; therapeutics are then developed for “optimal” targets. I describe a systems pharmacology approach that instead integrates systematic in-silico therapeutic perturbation with models of target/disease biology to identify conditions for optimal TI; non-intuitively optimal TI is sometimes achieved by pairing sub-optimal targets with therapeutics having appropriate properties.

MODELING MOLECULAR AND PATHOPHYSIOLOGICAL DATA

1:55 Chairperson’s Remarks

2:00 Predicting Adverse Side Effects of Drugs Using Systems Pharmacology

Jake Chen, Ph.D., Associate Professor, Indiana University School of Informatics & Purdue University Department of Computer Science; Director, Indiana Center for Systems Biology and Personalized Medicine

A new way of studying drug toxicity is to incorporate biomolecular annotation and network data with clinical observations of drug targets upon drug perturbations. I will describe the development of a novel computational modeling framework, with which we demonstrated the highest drug toxicity prediction accuracies ever reported by far. Adoption of this framework may have profound practical drug discovery implications.

2:30 Holistic Integration of Molecular and Physiological Data and Its Application in Personalized Healthcare

David de Graaf, Ph.D. President and CEO, Selventa

There are multiple industry-wide challenges in aggregating molecular and pathophysiological data for systems pharmacology to transform the process of drug discovery and development. One of the ways to address these challenges is to utilize a common computable biological expression language (BEL) that can provide a comprehensive knowledge network for new discoveries. An application of BEL and its use in identifying clinically relevant predictive biomarkers for patient stratification will be presented.

3:00 The Role of Informatics in ADME Pharmacogenetics

Boyd SteereBoyd Steere, Ph.D., Senior Research Scientist, Lilly Research Laboraories, IT Research Informatics, Eli Lilly

The leveraging of pharmacogenetics to support decisions in early-phase clinical trial design requires informatics methods to integrate, visualize, and analyze heterogeneous data sets from many different discovery platforms.  This presentation describes challenges and solutions in making sense of diverse sets of genetic, protein, and metabolic data in support of ADME pharmacology projects.

3:30 A Systems Pharmacology Approach to Understand and Optimize Functional Selectivity for Non-Selective Drugs

Joshua Apgar, Principal Scientist, Systems Biology, Dept. of Immunology & Inflammation, Boehringer Ingelheim Pharmaceuticals, Inc.

Most commonly the selectivity of a compound is defined in an in vitro or cellular assay, and it is thought of as principally a function of the binding energy of the drug to its on-target and off-target proteins; however, in vivo functional selectivity is much more complicated, and is affected by systems level effects such as multiple feedback processes within and between the various on- and off-target pathways. These systems level processes are often impossible to reconstruct in vitro as they involve many cell types, tissues, and organs systems throughout the body. We show here that through mathematical modeling we were able to identify, in silico, molecular properties that are critical to driving functional selectivity. The models, although simple, capture the key systems pharmacology needed to understand the on- an off- target effects. Surprisingly, in this case, the key driver of functional selectivity is not the affinity of the drugs but rather the pharmacokinetics, with drugs having a short half-life predicted to be the most functionally selective.

Tool Identifies Risk in Stenting ACS Patients

By Todd Neale, Senior Staff Writer, MedPage Today

Published: November 19, 2012
Reviewed by Dori F. Zaleznik, MD; Associate Clinical Professor of Medicine, Harvard Medical School, Boston and Dorothy Caputo, MA, BSN, RN, Nurse Planner

A new, easy-to-calculate risk score developed for patients with non-ST-segment elevation acute coronary syndromes (ACS) undergoing percutaneous coronary intervention (PCI) had better prognostic accuracy than other widely used risk scores, researchers found.

The ACUITY-PCI risk score includes six variables — insulin-treated diabetes, renal insufficiency, baseline cardiac biomarker elevation or ST-segment deviation, presence of a bifurcation lesion, small vessel/diffuse coronary artery disease, and extent of coronary artery disease, according to Gregg Stone, MD, of Columbia University Medical Center in New York City, and colleagues.

The 1-year rate of death or MI significantly increased from 5.3% in the lowest risk tertile to 9.1% in the middle tertile to 19% in the highest tertile (P<0.001), the researchers reported in the November issue of JACC: Cardiovascular Interventions.

Discrimination and calibration were greater with the ACUITY-PCI score than with other established scores.

“Although the TIMI and the GRACE scores have been shown to be valuable prognostic tools at the time of hospital admission for selecting pharmacological strategies and identifying those patients most likely to benefit from an invasive strategy, they have not been optimized for patients undergoing PCI and, thus, have relatively poor prognostic power to further risk stratify acute coronary syndrome patients undergoing PCI,” Stone and colleagues wrote.

“The ACUITY-PCI score is therefore intended to supplement the TIMI and GRACE scores when an invasive strategy has been undertaken and PCI is being considered.”

The researchers created the risk score using data from 1,692 patients enrolled in the angiographic substudy of the ACUITY trial, which was a comparison of heparin plus a glycoprotein IIb/IIIa inhibitor, bivalirudin (Angiomax) plus a glycoprotein IIb/IIIa inhibitor, or bivalirudin alone in patients with ACS undergoing an early invasive strategy. They then validated the score using another 846 patients from the same study.

Multivariate analysis revealed six variables that were significantly associated with 1-year mortality and MI and were included in the score. The researchers assigned points based on the strength of the predictor:

  • Insulin-treated diabetes (12 points)
  • Renal insufficiency (12 points)
  • Baseline cardiac biomarker elevation or ST-segment deviation (8 points)
  • Bifurcation lesion (4 points)
  • Small vessel/diffuse coronary artery disease (2 points)
  • Extent of coronary artery disease (1 point for each 10 mm of disease)

The C-statistic for the risk score — a measure of discrimination — was 0.67 in the derivation cohort and 0.70 in the validation cohort. In the validation cohort, the chi-square statistic for calibration was 6.2 and the index of separation was 0.44.

All of those values were better than those seen for four other established risk scores — TIMI, GRACE, SYNTAX, and Clinical SYNTAX. In addition, the net reclassification improvement with the new score ranged from 9% to 38% and the integrated discrimination index varied from 1.9% to 2.7%.

The researchers noted that the ACUITY-PCI score also was a good predictor of 1-year definite or probable stent thrombosis, with a C-statistic of 0.72.

In another study in the same journal, George Dangas, MD, PhD, of Mount Sinai Medical Center in New York City, and colleagues — including Stone — reported on the development of a risk score specifically for stent thrombosis in patients with ACS undergoing PCI.

The study included 6,139 patients from the HORIZONS-AMI and ACUITY trials, which included those with ST-segment elevation MI (STEMI) in the former trial and those with non-STEMI and unstable angina in the latter. The researchers used 4,093 patients for the derivation cohort and 2,046 for the validation cohort.

The risk score included 10 variables that were significantly associated with the risk of Academic Research Consortium-defined definite or probable stent thrombosis at 1 year:

  • Type of acute coronary syndrome (4 points for STEMI, 2 points for non-ST-segment elevation ACS with ST deviation, and 1 point for non-ST-segment elevation ACS without ST changes)
  • Current smoking (1 point)
  • Insulin-dependent diabetes (2 points)
  • Prior PCI (1 point)
  • Baseline platelet count (1 point for 250 to 400 K/µL and 2 points for more than 400 K/µL)
  • Absence of pre-PCI heparin therapy (1 point)
  • Aneurysmal/ulcerated lesion (2 points)
  • Baseline TIMI flow grade 0/1 (1 point)
  • Final TIMI flow grade less than 3 (1 point)
  • Number of treated vessels (1 point for two vessels and 2 points for three vessels)

Scores from 1 to 6 are considered low risk, 7 to 9 are intermediate risk, and 10 or higher are high risk.

The rates of stent thrombosis at 1 year were 1.36%, 3.06%, and 9.18% across the three risk tertiles in the derivation cohort (P<0.001 for trend), with a similar trend seen in the validation cohort.

The C-statistics were 0.67 in the derivation cohort and 0.66 in the validation cohort. Performance was comparable for events occurring both early (within the first 30 days) and late (from 1 month to 1 year).

“We believe that the development and initial validation of this stent thrombosis risk score can be a useful tool for both clinical practice and future clinical investigation (future analyses of trials or registries), as it can be a simple way to risk stratify patients immediately following a procedure,” Dangas and colleagues wrote. “The risk score could also be used in the informed consent process to better inform patients of their individual risk of stent thrombosis.”

But Ron Waksman, MD, and Israel Barbash, MD, of MedStar Washington Hospital Center in Washington, D.C., noted some limitations of the tool, including the pooling of different types of patients, the exclusion of important variables associated with stent thrombosis risk, and the use of mostly first-generation drug-eluting stents in the trials.

“It is imperative that the user of such a prediction tool be aware of its capabilities and performance, as well as its limitations, in various clinical scenarios,” they wrote in an accompanying editorial.

“A newly developed risk score for stent thrombosis should be robust and should be tested across broad study populations, stents, and antiplatelet regimens. A new model should also be validated in a setting different from the one in which it was derived,” they wrote. “Unfortunately, this is not the case with the newly proposed model.”

“Until such an encompassing tool is developed and validated,” they wrote, “one should rely on the known stent thrombosis risk factors and tailor an appropriate treatment for each patient.”

The ACUITY trial was funded by The Medicines Company and Nycomed.

Stone has served as a consultant to Abbott Vascular, Boston Scientific, Medtronic, and The Medicines Company. His co-authors reported relationships with Abbott, Regado, Ortho McNeil, Janssen, Merck, Maya Medical, AstraZeneca, Sanofi/Bristol-Myers Squibb, Eli Lilly, and Daiichi Sankyo.

The HORIZONS-AMI trial was supported by the Cardiovascular Research Foundation, with grant support from Boston Scientific and The Medicines Company.

Dangas has received speaker honoraria from AstraZeneca, Bristol-Myers Squibb, The Medicines Company, sanofi-aventis, and Abbott Vascular. His co-authors reported relationships with sanofi-aventis, The Medicines Company, Abbott Vascular, Bristol-Myers Squibb, Cordis, AstraZeneca, Daiichi Sankyo, Eli Lilly, Maquet, Roche, Boehringer Ingelheim, Liposcience, Merck, Pozen, Gilead Sciences, WebMD, the NIH, Pfizer, Johnson & Johnson, Schering-Plough, Merck Sharpe and Dohme, GlaxoSmithKline, Regado Biosciences, Boston Scientific, and Bristol-Myers Squibb/Sanofi.

Abstract

Although recent studies have revealed that heart cells are generated in adult mammals, the frequency of generation and the source of new heart cells are not yet known. Some studies suggest a high rate of stem cell activity with differentiation of progenitors to cardiomyocytes. Other studies suggest that new cardiomyocytes are born at a very low rate, and that they may be derived from the division of pre-existing cardiomyocytes. Here we show, by combining two different pulse-chase approaches-genetic fate-mapping with stable isotope labelling, and multi-isotope imaging mass spectrometry-that the genesis of cardiomyocytes occurs at a low rate by the division of pre-existing cardiomyocytes during normal ageing, a process that increases adjacent to areas of myocardial injury. We found that cell cycle activity during normal ageing and after injury led to polyploidy and multinucleation, but also to new diploid, mononucleate cardiomyocytes. These data reveal pre-existing cardiomyocytes as the dominant source of cardiomyocyte replacement in normal mammalian myocardial homeostasis as well as after myocardial injury.

Source of New Heart Cell Growth Discovered

A study in mice suggests that new heart cells arise from pre-existing heart cells and that the renewal process slows with age. The findings may lead to improved regenerative therapy for people with heart damage.

Dividing heart cells in newborn mice incorporate a tracer that can be seen in the cells’ nuclei. The color scale at the bottom shows the intensity of the tracer signal, with higher intensity toward the right side. Image by Senyo et al., courtesy of Nature.

The heart’s muscle cells, called cardiomyocytes, don’t readily replenish themselves. So an injured heart isn’t easy to mend. After a heart attack, a significant number of cardiomyocytes die. This jeopardizes heart function and can lead to chronic heart failure and possibly death. To help heal damaged hearts, scientists have been searching for a group of cells in the heart that can replenish damaged tissue.

Recent research has shown that the human heart generates new cardiomyocytes throughout its lifespan, but how frequently the cells are generated and where they come from is still debated. Studying heart tissue and cell turnover rate is technically very challenging. Some research has hinted that new cells can arise from progenitor cells at a fairly high rate. Other work has suggested that pre-existing cardiomyocytes divide at a fairly low rate to give rise to new cells.

A team led by Dr. Richard T. Lee of Brigham and Women’s Hospital and Harvard Medical School applied novel technology to investigate heart cell regeneration in mice. They used a technique called multi-isotope imaging mass spectrometry (MIMS). MIMS can detect nonradioactive stable isotope tracers. In contrast to most other tracers, these don’t alter biochemical reactions and aren’t harmful to the organism.

The scientists incorporated a rare stable isotope of nitrogen, nitrogen-15 (15N), into thymidine—one of the building blocks of DNA. When cells divide, the [15N] thymidine is taken up and added to new DNA. It can then be seen in the cells’ nuclei using MIMS. The work was supported in part by several NIH institutes, including the National Institute on Aging (NIA) and National Heart, Lung and Blood Institute (NHLBI). The study appeared online on December 5, 2012, in Nature.

To study cell turnover at different ages, the scientists gave 3 groups of mice [15N] thymidine for 8 weeks starting at day 4 (newborn), 10 weeks (young adult) or 22 months (old adult). To distinguish which types of cells created new cardiomyocytes, they performed similar experiments in mice genetically engineered with fluorescent tags to mark cardiomyocytes.

The scientists found that new heart cells were generated from pre-existing cardiomyocytes rather than progenitor cells. They estimated a yearly renewal rate of less than 1% during normal, healthy conditions. The rate of cell regeneration, they found, declined with age.

The team next used MIMS to study cell turnover following a heart attack. In the 8 weeks after the damage, roughly 3% of heart cells regenerated in the area next to the injured site. However, the researchers also noted that many cells had taken up 15N but not completed cell division.

“Our data show that adult cardiomyocytes are primarily responsible for the generation of new cardiomyocytes and that as we age, we lose some capacity to form new heart cells,” Lee says. “This means that we are losing our potential to rebuild the heart in the latter half of life, just when most heart disease hits us. If we can unravel why this occurs, we may be able to unleash some heart regeneration potential.”

Pathologists May Be Healthcare’s Rock Stars of Big Data in Genomic Medicine’s ’Third Wave’

Published: December 17 2012

Pathologists are positioned to be the primary interpreters of big data as genomic medicine further evolves

Pathologists and clinical laboratory managers may be surprised to learn that at least one data scientist has proclaimed pathologists the real big data rock stars of healthcare. The reason has to do with the shift in focus of genomic medicine from therapeutics and presymptomatic disease assessment to big data analytics.

In a recent posting published at Forbes.com, data scientist Jim Golden heralded the pronouncement of Harvard pathologist Mark S. Boguski, M.D., Ph.D., FACM. He declared that “The time of the $1,000 genome meme is over!”

DNA Sequencing Systems and the $1,000 Genome

Golden has designed, built, and programmed DNA sequencing devices. He apprenticed under the Human Genome program and spent 15 years working towards the $1,000 genome. “I’m a believer,” he blogged. “[That’s] why I was so intrigued [by Boguski’s remarks].

Boguski is Associate Professor of Pathology at the Center for Biomedical Informatics at Harvard Medical School and the Department of Pathology at Beth Israel Deaconess Medical Center. It was in a presentation at a healthcare conference in Boston that Boguski pronounced that it is time for the $1,000 genome to go.

“Big data analytics” will be required for translational medicine to succeed in the Third Wave of Genetic Medicine. That’s the opinion of Mark S. Boguski, M.D., Ph.D., who is a pathologist-informatist at Harvard Medical School and Beth Israel Deaconess Medical Center. Boguski predicts that pathologists are positioned to become the “rock stars” of big data analytics. For pathologists and clinical laboratory administrators, that means that big computer power will become increasingly important for all medical laboratories. (Photo by Medicine20Congress.com.)

Both Golden and Boguski acknowledged the benefits generated by the race to the $1,000 genome. Competition to be first to achieve this milestone motivated scientists and engineers to swiftly drive down the cost of decoding DNA. The result was a series of advances in instrumentation, chemistry, and biology.

Pathologists and Big Data Analytics

“Our notions about how genome science and technology would improve health and healthcare have changed,” Boguski wrote in an editorial published at Future Medicine. He then noted that the focus has shifted to big data analytics.

In the editorial, Boguski described the phases of development of genomic medicine as “waves.” The first wave occurred during the mid- to late-1990s. It focused on single- nucleotide polymorphisms (SNP) and therapeutics.

Medical Laboratories Have Opportunity to Perform Presymptomatic Testing

The second wave focused on presymptomatic testing for disease risk assessment and Genome Wide Association Studies (GWAS). Researchers expected this data to help manage common diseases.

The first two waves of medical genomics were conducted largely by the pharmaceutical industry, as well as with  primary care and public health communities, according to Boguski. Considerable optimism accompanied each wave of medical genomics.

“Despite the earlier optimism, progress in improving human health has been modest and incremental, rather than paradigm-shifting,” noted Boguski, who wrote that,to date, only a handful of genome-derived drugs have reached the market. He further observed that products such as direct-to-consumer genomic testing have proved more educational and recreational than medical.

“Third Wave” of Genomic Medicine

It was rapid declines in the cost of next-generation DNA sequencing technologies that now has triggered the third wave of genomic medicine. Its focus is postsymptomatic genotyping for individualized and optimized disease management.

“This is where genomics is likely to bring the most direct and sustained impact on healthcare for several reasons,” stated Boguski. “Genomics technologies enable disease diagnosis of sufficient precision to drive both cost-effective [patient] management and better patient outcomes. Thus, they are an essential part of the prescription for disruptive healthcare reform.”

Boguski reiterated the case for the value of laboratory medicine. He stated the following critical—but often overlooked—points, each of which is familiar to pathologists and clinical laboratory managers:

1. Pathologist-directed, licensed clinical laboratory testing has a major effect on clinical decision-making.

2. Medical laboratory testing services account for only about 2% of healthcare expenditures in the United States.

3. Medical laboratory services strongly influence the remaining 98% of costs through the information they provide on the prevention, diagnosis, treatment, and management of disease.

Molecular Diagnostics Reaching Maturity for Clinical Laboratory Testing

“Genome analytics are just another technology in the evolution of molecular diagnostics,” Boguski declared in his editorial.

Comment & Response

Right now the cost of the testing and the turnaround times are not favorable. It is going to take a decade or more for clinical labs to catch up. For some time it will be send out tests to Quest, LabCorp, and State or University lab consortia.

The power of the research technology is pushing this along, but for Personalized Medicine the testing should be coincident with the patient visit, and the best list of probable issues should be accessible on the report screen. The EHR industry is dominated by 2 companies that I see have no interest in meeting the needs of the physicians. The payback has to be on efficient workflow, accurate assessment of the record, and timely information. The focus for 25 years has been on billing structure. But even the revised billing codes (ICD10) can’t be less than 5 years out-of-date because of improvements in the knowledge base and improvements in applied math algorithms.

The medical record still may have information buried min a word heap, and the laboratory work is a go-to-you know where sheet with perhaps 15 variables on a page, with chemistry and hematology, immunology, blood bank, and microbiology on separate pages. The ability of the physician to fully digest the information with “errorless” discrimination is tested, and the stress imposed by the time for each patient compromises performance. There is work going on in moving proteomics along to a high throughput system for improved commercial viability, that was reported by Leigh Anderson a few years ago. The genomics is more difficult, but the genomics is partly moving to rapid micropanel tools.

In summary, there are 3 factors:

1. Automation and interpretation
2. Integration into the EHR in real time and usable by a physician.
3. The sorting out of the highest feature “predictors” and classifying them into clinically meaningful sets and subsets.

When this is done, then the next generation of recoding will be in demand.

Abstract

Introduction: We propose an automated nutritional assessment (ANA) algorithm that provides a method for malnutrition risk prediction with high accuracy and reliability.

Materials and Methods: The database used for this study is a file of 432 patients, where each patient is described by 4 laboratory parameters and 11 clinical parameters. A malnutrition risk assessment of low (1), moderate (2) or high (3) was assigned by a dietitian for each patient. An algorithm for data organization and classification via characteristic metrics is proposed. For each patient, the algorithm characterizes its unique profile and builds a characteristic metric to identify similar patients who are mapped into a classification.

Results: The algorithm assigned a malnutrition risk level for each patient based on different training sizes that were taken out of the data.

Our method resulted in an average error (distance between the automated score and the real score) of 0.386, 0.3507, 0.3454, 0.34 and 0.2907 for 10%, 30%, 50%, 70% and 90% training sizes, respectively.

Our method outperformed the compared method even when our method used a smaller training set then the compared method. In addition, we show that the laboratory parameters themselves are sufficient for the automated risk prediction and organize the patients into clusters that correspond to low, low-moderate, moderate, moderate-high and high risk areas.

Discussion: The problem of rapidly identifying risk and severity of malnutrition is crucial for minimizing medical and surgical complications. These are not easily performed or adequately expedited. We characterize for each patient a unique profile and map similar patients into a classification. We also find that the laboratory parameters themselves are sufficient for the automated risk prediction.

Aspirin Use, Tumor PIK3CA Mutation, and Colorectal-Cancer Survival

BACKGROUND

Regular use of aspirin after a diagnosis of colon cancer has been associated with a superior clinical outcome. Experimental evidence suggests that inhibition of prostaglandin-endoperoxide synthase 2 (PTGS2) (also known as cyclooxygenase-2) by aspirin down-regulates phosphatidylinositol 3-kinase (PI3K) signaling activity. We hypothesized that the effect of aspirin on survival and prognosis in patients with cancers characterized by mutated PIK3CA (the phosphatidylinositol-4,5-bisphosphonate 3-kinase, catalytic subunit alpha polypeptide gene) might differ from the effect among those with wild-type PIK3CA cancers.

METHODS

We obtained data on 964 patients with rectal or colon cancer from the Nurses’ Health Study and the Health Professionals Follow-up Study, including data on aspirin use after diagnosis and the presence or absence of PIK3CA mutation. We used a Cox proportional-hazards model to compute the multivariate hazard ratio for death. We examined tumor markers, including PTGS2, phosphorylated AKT,KRAS, BRAF, microsatellite instability, CpG island methylator phenotype, and methylation of long interspersed nucleotide element 1.

RESULTS

Among patients with mutated-PIK3CA colorectal cancers, regular use of aspirin after diagnosis was associated with superior colorectal cancer–specific survival (multivariate hazard ratio for cancer-related death, 0.18; 95% confidence interval [CI], 0.06 to 0.61; P<0.001 by the log-rank test) and overall survival (multivariate hazard ratio for death from any cause, 0.54; 95% CI, 0.31 to 0.94; P=0.01 by the log-rank test). In contrast, among patients with wild-type PIK3CA, regular use of aspirin after diagnosis was not associated with colorectal cancer–specific survival (multivariate hazard ratio, 0.96; 95% CI, 0.69 to 1.32; P=0.76 by the log-rank test; P=0.009 for interaction between aspirin and PIK3CA variables) or overall survival (multivariate hazard ratio, 0.94; 95% CI, 0.75 to 1.17; P=0.96 by the log-rank test; P=0.07 for interaction).

CONCLUSIONS

Regular use of aspirin after diagnosis was associated with longer survival among patients with mutated-PIK3CA colorectal cancer, but not among patients with wild-type PIK3CA cancer. The findings from this molecular pathological epidemiology study suggest that thePIK3CA mutation in colorectal cancer may serve as a predictive molecular biomarker for adjuvant aspirin therapy.

Study Shows Aspirin Could Increase Survival in Colorectal Cancer Patients with PIK3CA Mutations

November 28, 2012

By mining epidemiological data from several long-term health studies and combining it with genomic data, a team led by the Dana-Farber Cancer Institute and Harvard Medical School has shown that colorectal cancer patients with PIK3CA mutations may benefit from treatment with aspirin, and that PIK3CA mutation status could serve as biomarker to predict response to aspirin treatment.

The study, published last month in the New England Journal of Medicine, evaluated data from 964 patients with colon or rectal cancer from the Nurses’ Health Study and the Health Professionals Follow-up Study. It found that patients with PIK3CA-mutated cancers who regularly took aspirin after their diagnosis had significantly longer survival, while those with wild-type cancers showed no benefit from aspirin treatment.

According to the researchers, led by Dana Farber’s Shuji Ogino, the results suggest that aspirin might be worth testing as an adjuvant treatment for the approximately 20 percent of colorectal cancer patients with PIK3CA mutations.

“What we conclude is that this PK3CA mutation can be a predictive biomarker and based on molecular testing, doctors could strongly or weakly recommend aspirin,” Ogino told PGx Reporter.

According to the group, numerous observational and other studies have suggested that aspirin might play a protective role in colorectal cancer. Aspirin is currently prescribed to some colorectal cancer patients, Ogino said, but so far there has been no way to predict which patients are likely to actually benefit from it.

Ogino said his team’s previous research found that levels of the enzyme PTGS2 could predict response to aspirin treatment, but the association didn’t reach statistical significance. And because of a lack of good standards for measuring PTGS2 using immunohistochemistry, the group wanted to search for a better, more objective marker.

According to the group, other experiments have suggested that as aspirin inhibits PTGS2 it also down-regulates PI3K signaling, which hinted that PIK3CA mutations could be a potential marker as well.

“Based on previous studies, we hypothesized that PIK3CA mutation may be a good marker for aspirin response,” Ogino said. Testing this hypothesis prospectively, he said, would have taken decades, but by using epidemiological data coupled with molecular data the group was able to find an answer much more quickly.

In the recent NEJM study, Ogino and his colleagues compared the survival of colorectal patients who reported that they regularly used aspirin after their diagnosis with those who didn’t, and further subdivided the group into those with PIK3CA mutations and those without.

The team studied samples from a subset of 964 patients from the two large longitudinal health studies for which the relevant aspirin use data was available, collecting specimens from the registries and using pyrosequencing to establish PIK3CA mutation status for each patient’s tumor. The group also recorded whether samples had BRAF or KRAS mutations.

The researchers found that patients with PIK3CA mutations who reported regular aspirin use had a significantly improved five-year survival rate — 97 percent — over those who didn’t take aspirin — 74 percent.

In contrast, patients without the mutation showed no difference in survival whether they took aspirin regularly or not.

Because the group had previously found that PTGS2 levels were also predictive of response to aspirin use, the researchers evaluated whether a combination of both markers could serve an even greater predictor. According to the study authors, the strongest effect of aspirin use was indeed in patients with both markers, though this finding did not have high statistical significance.

Because the study sampled patients treated before 2006, the group assumed that chemotherapy treatment was similar for the PIK3CA-mutated cases and the wild-type cases. According to the researchers, information on patients’ mutation status was not available to treating physicians at the time of the studies.

The team also distinguished between aspirin use before and after diagnosis, finding that pre-diagnosis use did not seem to influence the relationship between PIK3CA and post-diagnosis aspirin.

Ogino said that the group is pursuing avenues to validate the findings. Unfortunately, relatively few trials of aspirin treatment in colorectal cancer have been conducted.

One option, he said, would be to analyze data from a trial of celecoxib (Pfizer’s Celebrex), a similar drug to aspirin, instead. But it’s not an ideal solution. If the results reflect what the group found in its aspirin study it would shore up the aspirin finding. However, if the results do not match up it would be unclear what that might mean about the group’s original findings.

Potentially, the researchers could also use mouse models or cell lines, but this route has several downsides. Most important, Ogino said, is the fact that aspirin likely affects inflammation more than cancer cells themselves. “Cancer is not just the cancer cell, it’s a much more complicated system so you can’t assess it in the test tube, basically,” he said.

Conference Introduction

The past few years have witnessed a revolution in the understanding of health and disease, brought on in large part by the sequencing of the human genome and the creation of a map of human genetic variation. Personalized medicine is the translation of this knowledge to patient care by using genetic and genomic information in diagnosis, prognosis and treatment. The goal of personalized medicine is to provide the right diagnosis and treatment to the right patient at the right time at the right cost. Already there are abundant examples that personalized medicine is poised to transform healthcare by offering the possibility of improved health outcomes and the potential to make healthcare more cost-effective.

The eighth annual Personalized Medicine conference will take place November 28-29, 2012 at The Joseph B. Martin Conference Center at Harvard Medical School in Boston. This year’s two-day conference will once again bring the most current updates on Personalized Medicine and how recent experience may guide and inform the policies, plans and actions of stakeholders among government, academe and the private sector. Widely considered the premier event in the field, the conference attracts over 600 national and international thought leaders.

The conference reflects a distinctive collaboration of the Partners HealthCare Center for Personalized Genetic Medicine, Harvard Medical School and Harvard Business School. The alliance of these renowned academic enterprises presents an exceptional opportunity to address the integrating of medicine and business in facilitating personalized medicine.

Personal Tale of JL’s Whole Genome Sequencing

Word Cloud by Daniel Menzin

Unexpected scary findings: the tale of John Lauerman’s whole genome sequencing

FEBRUARY 15, 2012
Joe Thakuria draws John Lauerman's blood
Joe Thakuria draws John Lauerman’s blood for whole genome sequencing. By Madeleine Price Ball, licensed under CC-BY-SA.

Madeleine Price Ball, PhD is a PGP research scientist in George Church’s lab at Harvard Medical School.

Several months ago John Lauerman, a reporter for Bloomberg News, approached the Personal Genome Project interested in having his whole genome sequenced. While we have hundreds of genomes in the sequencing pipeline, of the dozen or so genomes we have sequenced to-date, so far the results have been for the most part uneventful.

Lauerman’s case was different: we found something rare and “famous”, and something that nobody could have anticipated by looking through family history: a mutation that was acquired rather than inherited. This genetic variant (JAK2-V617F) is one of a number of mutations that can accumulate in blood stem cells, a precursor that could lead to several rare blood diseases.

Last night Lauerman published his experience, and we encourage all participants to read it. It confronts us with a scenario that seems likely to affect others who forge into this new and unknown territory: the very real possibility that whole genome sequencing may uncover something unexpected, ambiguous, and scary. This certainly isn’t an outcome we anticipate for most participants, but it is a rare possibility all should be aware of. Would you rather know that you carry such a variant, even if that knowledge might not help your health at all? Although some would decline, PGP participants are the sort of people who say: “Yes, I’ll take that risk, I’d rather know!” [see footnote]

His experience also illustrates potential for the Personal Genome Project to guide health care, for himself and for those who follow. The JAK2-V617F variant is so rarely seen in healthy individuals, we have very little understanding of what to expect. It has almost always been seen after a patient is diagnosed with a disease, not before. Will he develop one of these diseases? If so, which one? Perhaps many people carry the variant but never develop any symptoms of disease. In coming years Lauerman will likely continue to monitor his blood for signs of disease. It is possible that he will never develop the disease, and we hope this is the case. On the other hand, through monitoring he may detect disease sooner than he otherwise would have. By making his experiences public, his case can inform future individuals who confront the same finding.

As we move onward to sequencing hundreds and thousands of genomes, we can’t promise such interpretations will be made in a timely manner. We’re working with other groups to improve our ability to interpret genomes — and PGP participants are the perfect testbed for this development! — but it’s much harder than you might think. Genome data is made public in 30 days, but months or even years could pass before a serious and potentially scary variant is noticed. Participating in the PGP not only means that you risk learning ambiguous and scary news, but that it may be uncovered long after your data has been made public. We are always grateful to participants who choose to step into that unknown territory of genome sequencing, and who share their data so that others may learn.


Footnote: In the early stages of enrollment, individuals interested in joining the Personal Genome Project are asked to think about whether there are specific types of genetic information that they might not want to learn about themselves. Our examples include medical conditions with no effective cures or therapies, cancer, degenerative diseases, and stigmatized traits (e.g. mental illness). We do not offer the review or redacting of such information on a case-by-case basis. Only participants who wish to take the risk of learning such information are allowed to proceed with enrollment.

Harvard Mapping My DNA Turns Scary as Threatening Gene Emerges

By John Lauerman – Feb 15, 2012 12:01 AM ET

Four months after I walked into a lab at Harvard University and gave a vial of blood to have my genome sequenced, my search to understand my DNA led me to Mark Sanders, a former Indiana firefighter.

It took a little while to explain why I was calling and then he told me his story:

Feb. 15 (Bloomberg) — Bloomberg News reporter John Lauerman talks about the results of his genome sequencing. The genome contains the DNA instructions for making all the body’s cells and tissues. Lauerman discussed the report with a team from Harvard Medical School’s Personal Genome Project, who will use the results in their efforts to better understand variations in the human genome and their implications for health and disease.

Deep Breath

After recovering, Sanders retired from firefighting to garden and play the fiddle. He knows other myelofibrosis patients who haven’t fared as well.

“I had been so physically fit all my life,” he said. “There’s no reason or rhyme to why I have it or got it, and there’s not a lot of people around you can talk to who have it.”

I hung up the phone and took a deep breath. DNA in his blood cells carried the same rare genetic variant that my sequencing had revealed.

The variant is linked to a group of blood disorders, of which primary myelofibrosis is the most serious. Doctors don’t know whether this gene variant itself causes disease, yet it is seen so often in three blood disorders that its presence is used to confirm their diagnosis. I had to consider that my future might hold a fate similar to Sanders’s.

Genome-Sequencing Report

My path to Sanders began on Monday, Jan. 2, when I was sitting alone in my office in downtown Boston. Just after 4 p.m., I got an e-mail message from Madeleine Ball, a Harvard University researcher, telling me that the results of my genome sequencing were ready. The procedure is gaining use in cancer clinics and children’s hospitals, and will become increasingly common as the cost drops to $1,000, no more than that of many diagnostic procedures, such as MRI or colonoscopy, manufacturers and researchers say.

Before even a minute had gone by, the lengthy report was there for me to view.

“Here it is,” I thought, clicking on my inbox. “Mortality in an e-mail.”

Even as my DNA was chopped up, labeled, photographed and decoded by machines in California, the speed and power of sequencing was exploding. Life Technologies Corp. (LIFE) said Jan. 10 that its new Ion Proton machine will be able to sequence an entire genome in a day, for $1,000. Last month,Roche Holding AG (ROG) made a $5.7 billion hostile bid forIllumina Inc. (ILMN), which said it will also soon have machines that can provide 24-hour genome sequencing. Google Inc. (GOOG) and Amazon.com Inc. were investing in technologies to manage the tidal wave of information coming from these machines.

Personal Struggle

Now my own deciphered genome, the chemical instructions for making all the cells and tissues of my body, was complete. That evening marked the start of a medical and personal struggle to understand the report’s findings. The genome rules our bodies in ways that remain enigmatic. Many of the diseases and medical conditions I thought would emerge in the analysis, didn’t. At the same time, there were unpleasant surprises that cast a shadow on my future and now confront me and my family with tough medical decisions.

Before my sample was taken, I met with Denise Lautenbach, a genetic counselor who works in research programs at Harvard Medical School. We’d discussed the possible revelations that might come. My father, grandfather and some uncles have suffered from a shaking disorder called essential tremor. I worried about other conditions that run in my family, such as thyroid disease, diabetes and depression. While dementia isn’t a theme, I was curious about whether I have the APOE4 gene variant that raises the risk of Alzheimer’s disease.

Breast Cancer Risk

I also prepared by speaking with others who have had their genomes sequenced. Greg Lucier, chief executive officer of sequencer maker Life Technologies, discovered he has a gene that might raise the risk of breast cancer in himself and his daughter. Would I find out the same thing? What about far rarer conditions, such as amyotrophic lateral sclerosis and Huntington’s disease, both of which can be predicted by sequencing?

My mind raced as I scanned the results that late Monday afternoon, looking for familiar words and phrases that might be connected to other conditions that run in my family.

Good Report

It appeared to be a good report. I saw a genetic variant linked to slightly higher-than-normal risk of an age-related eye disease called macular degeneration. No surprise; about 10 percent of the U.S. develops this condition, and my mother has it. There was a variant linked to higher schizophrenia risk; again, not a huge boost in odds of a disease that affects about 1 percent of the population (and which I’m probably too old to develop). There were gene variants linked to liver and bowel disease, neither of which I suffer from.

Then my eyes were drawn back to the top of the report and a variant called JAK2-V617F. I realized then that the list was ranked in order of medical importance. Clicking on an entry brought me to a few pages of medical information, and those pages were linked to published scientific and medical studies. I began reading about JAK2 more closely.

This wasn’t good. The report classified the JAK2 variant’s clinical importance as “high,” and its impact as “well- established pathogenic,” meaning harmful. It’s seen frequently in people with rare “cancer-like” blood diseases. Indeed, as the report said, doctors test for the JAK2 variant to confirm cases of these diseases, called myeloproliferative disorders.

Unclear View

Did that mean that I already had a rare disease? My eyes widened. I read on.

Researchers currently see the variant as “one of an accumulation of changes that leads to the development of these cancer-like diseases,” the report said. “It is unclear how to view the presence of the variant in people who don’t have symptoms of the disease.”

After about 40 minutes of reading and thinking, I remained mystified. The report said “cancer-like.” I kept staring at the word “cancer,” while the companion “like” seemed to disappear. I’ve written about other people’s illnesses for years. What had started out as a cutting-edge science story was beginning to feel more like an unsettling visit to the doctor’s office with its confusion, struggles to understand, and shivers of dread.

Puzzling Medical News

“How worried should I be?” I kept thinking. Anticipation had been building inside me for months. Now my results were here and I barely knew what to make of the most important one.

I picked up the phone and called my wife, Judi, who’s a nurse. After 21 years of marriage, we’re accustomed to regular discussions of medical issues, in part because Judi has type 1 diabetes, which requires daily monitoring and insulin. Still, this was some of the most serious and puzzling medical news I’d ever received. I was careful to keep from sounding frightened.

“I got my results,” I said when she picked up the phone. I poured out the details, focusing on the JAK2 variant.

Judi’s voice was calm. I didn’t have any of the symptoms of diseases associated with the gene, she said. I’m usually energetic and active; that meant it wasn’t clear what the variant meant in my case.

“At least if there is a problem, we’ll find it earlier if you’re evaluated yearly,” she said.

“They told me that none of these results should be used to make medical decisions,” I said. “I’ll meet with the researchers later this week to talk about everything.”

New Chapter?

We agreed that, overall, the report was good news. I didn’t realize there was more news to come.

I left the office and got on my bike, which I had ridden to work that day. I pedaled carefully to make it home safely through the streets of Boston, which is never guaranteed, genes or no genes.

Three days after getting my results, I took a seat in the office of George Church, the Harvard scientist who started the Personal Genome Project that arranged my sequencing. Joe Thakuria, the clinical geneticist and project medical director who took my blood sample in this same office in September, was there to lead the discussion of my results. The team had been through meetings like this before, having analyzed and released the genomes of 10 people, including Church, in 2008. I was already feeling a stomach full of emotions: was this about to be a new chapter in my life? And if so, how long would that chapter be?

Thakuria asked if I had any questions before we began. I told them how thrilled I was that I hadn’t seen certain genes that I expected given my family’s medical history, such as the variant for essential tremor. I’d seen nothing in my report about Alzheimer’s risk, which I considered a good sign.

Not Bad News

The researchers stopped me. The technology used to sequence my DNA has difficulty penetrating certain portions of the genome. One such region contains the gene that makes a blood fat called apolipoprotein E. Consequently, my results might not show whether I have the version of a gene, called APOE4, which raises the risk of Alzheimer’s disease.

Never mind, I thought. I can live without that knowledge.

The absence of the gene for benign tremor, the condition my father and grandfather had, wasn’t necessarily such good news, the team explained. As-yet unknown genes might cause the same condition. No news wasn’t always good news; it just wasn’t bad news.

‘Very Rare’

With the three of us, along with Ball and Alexander Zaranek, another project researcher, crowded around the table in Church’s office, the team then turned to the JAK2 variant. The appearance of the gene in my blood had surprised even the Harvard scientists.

“This is probably the most serious variant that we’ve actually seen to date in the study,” Thakuria said. “It’s very rare.”

The JAK2 gene contains the DNA code for making a protein used to send signals through cells. About two out of 1,000 people have the V617F variant, which was discovered in 2005 and appears to encourage blood cells to grow and divide.

Many scientists believe it’s an acquired gene variant, meaning that I wasn’t born with it and my children and other blood relatives probably don’t have it. While JAK2 may have arisen in response to my own habits, at this point, it’s unclear what may have led to the mutation.

Blood Disorders

The JAK2 variant is found in about 90 percent of people with polycythemia vera, an oversupply of red blood cells. This disease is usually treated with drugs or phlebotomy, the draining of some blood from the system. It’s also frequently found in patients with essential thrombocytosis, an overproduction of platelets that usually requires no treatment and can be addressed with blood-thinners when patients have symptoms. It’s also used to diagnose primary myelofibrosis, the condition Sanders, the former firefighter, had. About 10 percent of these cases can develop into dangerous leukemias.

That’s three conditions linked to one gene. One of the three has a possibility of becoming cancerous, Thakuria said.

“I don’t want you to fret about this,” he said. It was the first of several times I would hear him say it.

At that point, Thakuria opened up a link to a 2010 study attached to the report. Scientists have been conducting studies of individual genes for years. The team had found a study of 10,507 people in Copenhagen who gave blood samples and then were followed for as long as 18 years. The Copenhagen researchers went back and analyzed the blood samples; 18 had the JAK2 variant.

‘Very Scary Figure’

What it showed was that 14 of the 18 people with the variant developed cancer in their lifetimes. All of the 18 died within the study period.

“That’s a very scary figure,” Thakuria said.

Information was starting to wash over me without really penetrating. I struggled to keep thinking of good questions for the team. Instead, I started asking myself questions: “What am I doing here? What are these people telling me?” I searched the faces arrayed around me, trying to see whether any of the researchers looked as panicked as I felt.

I tried to listen closely as Thakuria explained what the variant and the study might mean. There were a number of shortcomings in the Copenhagen study that made it difficult to interpret, he said. For example, he said, the authors had been liberal in their use of the word “cancer.” Some of the disorders developed by patients with the JAK2 variant were of the milder variety such as polycythemia vera, which isn’t typically classified as a cancer.

Issue of Deaths

Then there was the issue of deaths. It wasn’t clear whether people with the variant had died of the conditions they had been diagnosed with, or other causes, Thakuria said. Half of them had died in their 80s, and seven had died in their 70s. This is not far from average life expectancy, he pointed out.

“Half of them could have died of bicycle accidents,” he said, smiling.

There were other reasons not to fret, Thakuria said. Although the JAK2 variant often shows up in these conditions, no one knows precisely what role it plays. It may be a cause of the disorders, or an effect of changes elsewhere in the genome. The JAK2 variant was unlikely to be the only cause of these diseases; several things — things that remain unknown to us — would probably have to go wrong before any disease would arise. In this context, the gene wasn’t quite so scary, Thakuria said.

Black and White

I thought about a conversation I’d had with Ball just a few days earlier, while my genome were still being analyzed. I had called to see when the results were coming. She said they were “interesting,” but didn’t want to discuss them until a clinical geneticist had a chance to review them. Her voice sounded like she didn’t want to reveal everything she knew.

“I wish everything were black and white,” she said. “Unfortunately, things just don’t turn out that way very often.”

The researchers said I now needed to confirm that the sequencing was correct with another round of testing using a different technique. I would give another blood sample. If the variant was there, we’d talk more about what steps to take.

The meeting lasted almost two hours, and I left Church’s office with Thakuria. We walked to a restaurant about halfway between Harvard Medical School and Fenway Park to sit and have a drink. I continued to quiz him on the relationship between the JAK2 variant and the diseases we’d been talking about.

Ask Again

Sitting on a barstool next to Thakuria and listening to him discuss the JAK2 variant, I felt reassured. It occurred to me that this wasn’t how most people would receive the news of their results. As a reporter working on a story about genomics, I had access to experts that many people wouldn’t. What will happen as more people get results from broad genome sequencing?

I spoke about this during a meeting with Harold Varmus, director of the U.S. National Cancer Institute, and a co-winner of a Nobel Prize in 1989 for his work to find genes that promote the growth of cancer cells. I mentioned I had just received my results.

“How do you feel?” he asked.

“It’s been an interesting process,” I said. “It’s still playing out.”

Varmus nodded. Gathering genetic data from thousands of people can help researchers understand health by correlating gene variations with diseases, he said. He was concerned, however, that companies may not always ensure that people who have undergone sequencing will get a full understanding of their results.

‘How to Deal’

“Accumulating the information and studying it is good,” he said. “My concern is whether individuals are getting guidance on how to deal with the information.”

“People are being told they have a certain gene variant. In a mass population, that increases the risk of some diseases by, say, two-fold. That might be true in a mass population, but in any single individual’s genome, it’s not certain what that means.”

The Harvard researchers are struggling with these same issues, and are still working to streamline and improve their approach to giving results to study participants, Thakuria said.

“As we get more information from participants like you, we’ll gain a much better understanding of how to do it,” Thakuria said.

Animal Studies

I still felt like someone who kept shaking a toy Magic 8 Ball and getting the message: “Concentrate and ask again.” I decided to do a little research on my own. I found a 2010 study in the journal Blood showing that when the JAK2 variant was added to the genomes of mice, the animals later suffered from disorders similar to those seen in people with the gene.

This is just one of several animal studies suggesting that the JAK2 variant contributes directly to blood disorders, said John Crispino, a professor at Northwestern University Feinberg School of Medicine, who studies the gene. Skeptics point out that drugs that interfere with JAK2 don’t cure patients suffering from the gene-linked blood disorders.

“The field is mixed,” he said. “My bias is that the JAK2 variant contributes to the pathology of the disease.”

I wanted to find out what kind of people have the JAK2 mutation I have, and what’s happened to them. In addition to Sanders, the Indiana firefighter, I spoke with Bob Rosen, chairman of theMPN Research Foundation, a Chicago-based advocacy group for people with myeloproliferative disorders, and he had a surprise for me.

Red Blood Cells

About 14 years ago, Rosen went to a doctor because of pain in his fingers and toes. A complete blood count revealed high levels of red blood cells. He was diagnosed with polycythemia vera and was first treated with phlebotomy. He now takes a drug that controls his blood cell levels. With his treatment, he’s still able to work out, and had been playing basketball on the day I called him.

“I’ve been lucky,” he said. “The risk is that, over time, new symptoms will emerge or there will be a progression to something worse.”

A small percentage of patients with polycythemia vera can develop more serious conditions, such as primary myelofibrosis and certain leukemias, Rosen said. I hadn’t realized this, or hadn’t absorbed it, until now.

Another Surprise

Then, another surprise arrived. Looking at my report, I saw it had been updated electronically, as the genome project research team had told me would happen from time to time. Now, the second entry on my list of variants was labeled “APOE- C130R” — that’s another name for the APOE4 gene associated with increased risk of Alzheimer’s disease.

I kept reading, recalling that I had been told my ApoE result wasn’t accessible with the technology used to sequence my genome. As it turned out, the technology had worked after all. I was at increased risk for Alzheimer’s.

This was exactly the kind of news I had hoped I wouldn’t receive.

A few days later I got an e-mail from Ball, of the Harvard team.

“Sorry this was missed earlier,” she said in the e-mail. She recommended that I look at the studies she’d collected on APOE4, some of which casts doubt on the role of the variant as a strong factor in causing Alzheimer’s. According to one estimate, people who have one copy of the gene, as I do, have a 3 percent increased risk of developing the disease by age 80.

Better to Know

One of my parents must have had this gene variant in order for me to get it. Yet my mother is in her late 70s and my father is 80; neither of them has Alzheimer’s disease. The longer I thought about it, the less I worried.

I talked with my two children, Hanna and James, about their feelings regarding the JAK2 and Alzheimer’s gene variants. My daughter, a sophomore in college, said she thinks it’s an advantage to be aware of a health threat.

“If there’s a treatment for it, you could start earlier,” she said. “It’s better to know.”

My next stop was to see my doctor. While she didn’t want her name used in this story, she agreed to let me write about our conversations and paraphrase her comments.

I followed an aide into an exam room. Nothing about my body had changed since the genome test was done. I still had normal blood pressure and pulse, and my weight was steady.

My doctor had heard of the JAK2 variant. If the result was confirmed, I would need to have my blood count tested. If there was an oversupply of red blood cells or platelets, or signs of damaged bone marrow, we would start thinking about treatment, such as removing blood. She asked me how I was feeling.

‘Not Sick’

“I feel fine,” I said. “I’m not sick.”

I didn’t mention that every time I thought about the JAK2 variant, itching followed. I had read that itching was one of the symptoms of polycythemia vera. Even as I write these words, I’m scratching my forehead. I never feel itchy when not thinking about my genome. I also started noticing memory lapses.

This kind of behavior is often called “medical student syndrome,” because doctors in training who are learning to diagnose new diseases turn their skills on themselves. I assumed it was this syndrome I was suffering from, rather than a blood disorder.

It seemed like a good time to return to the Boston office of Aubrey Milunsky, the director of the Boston University Center for Human Genetics who had warned me in May that having my genome sequenced would just cause me needless worry.

“Why would you want to know that?” he had asked me then.

Milunsky was well-acquainted with the JAK2 variant on my report. Just as the team at Harvard had said, he mentioned that there was little known about the long-term impact of the variant in people. He noted that it’s also associated with some cases of dangerous clotting in abdominal blood vessels.

“You know it’s there, but you don’t know what it means,” he said. “You’re smack in the territory of inviting anxiety into your life. And this may have no meaning whatsoever in your entire life.”

Useful Vigilance

I disagreed. The results had actually taken some uncertainty out of my life, I told Milunsky. We all bear some health risks, and that’s why doctors recommend, for instance, that everyone get regular checkups and those 50 and older undergo tests for colon cancer. I have a rare mutation linked to rare conditions, most cases of which can be treated. Wouldn’t it make sense for me to undergo a blood test regularly to see whether my blood counts had changed?

Such vigilance might be beneficial, and it might not, Milunsky said. I might live the rest of my life with my health unaffected by the variant. Yet the exercise had shown that I had discovered things I’d rather not know, he said. Others who undergo the same procedure will surely find out that they have mutations that practically guarantee they will develop serious and perhaps even fatal diseases, he said.

Huntington’s Disease

Indeed, a 1999 study in the American Journal of Human Genetics found that about 1 percent of 4,527 people who were told they had the gene that causes Huntington’s disease, a progressive nervous system disorder, attempted or committed suicide, or were hospitalized for psychiatric reasons.

Medical researchers are still trying to determine when it makes sense to do more common tests for breast and prostate cancer. A certain percentage of people who get positive results on these screening exams will go on to have unneeded treatment that may cause harm. In October, a government panel recommended that blood tests used to screen for prostate cancer should only be performed on men with symptoms. The same panel said in 2009 that women should start getting mammograms at age 50, rather than 40.

On Jan. 25, at about 11 p.m., I got a phone call from Thakuria. We had arranged to speak late in the day to accommodate busy schedules.

‘Mutation Confirmed’

“The mutation confirmed,” he said. He didn’t say “JAK2,” but I knew that was what he was talking about.

The next step for me is to have my white and red blood-cell levels measured, along with those of platelets. Doctors will also study the appearance of these cells under a microscope and check to see how much oxygen my blood can carry. I expect these tests to be normal. If they aren’t, it’s possible that I’ll start getting blood drawn from my system or drug treatment for polycythemia vera. I may need to take a blood thinner, such as aspirin, to counteract the effects of excess platelets. Should I have evidence of more serious disease, stronger treatment may be needed.

“I’m not going to lie to you: I’d rather you didn’t have it,” Thakuria said. “This isn’t like one of those mutations that have specific recommendations. There are no guidelines here. This is part of being on the frontier.”

Harvard Researchers’ New DNA Barcoding May Give Pathologists Expanded Capabilities in Fluorescence Microscopy 

November 5, 2012

New biomedical imaging technology could enhance pathologists’ ability to examine tissue samples via fluorescence microscopy
Scientists at Harvard University’s Wyss Institute for Biologically Inspired Engineeringhave developed a new DNA, barcoding technique. The fluorescence microscopy approach has significant implications for the imaging community.

Beyond imaging, however, pathologists will be able to use this same technology when evaluating tissue specimens.

The new method could enable simultaneous imaging of many different types of molecules in a single cell, according to Peng Yin, Ph.D., Associate Professor of Systems Biology at Harvard Medical School and Core Faculty Member at Wyss Institute. The developers expect the method to provide researchers with a richer, more accurate view of cell behavior than is possible using current techniques.

Pathologists Could Adopt DNA Barcoding for In Vitro Diagnostics

“We hope this new method will provide much-needed molecular tools for usingfluorescence microscopy to study complex biological problems,” stated Yin, the study’s co-author, in a recent press release.

Using DNA Origami to Create Fluorescent Linear DNA Barcodes
The newly engineered DNA barcode harnesses the natural ability of DNA to self-assemble. The basis of the new technology is a process called DNA origami. This enables scientists to arrange colored dots, or fluorophores, into geometric patterns, or fluorescent linear DNA barcodes.

These imaging probes translate a cell’s invisible biological information, such asproteins or RNA molecules, into detectable signals, noted a summary of Yin’s research on the Wyss website. These signals help researchers better understand the role of cell behavior in the onset and progression of disease.

New Barcode Could Offer a Virtually Unlimited Number of Styles

Scientists currently use fluorescence microscopy to pair fluorescent elements—the barcodes—with molecules they know will attach to the part of the cells they want to investigate. When they illuminate the sample, it triggers each kind of barcode to fluoresce at a particular wavelength of light, which indicates the location of the molecules of interest.

However, the multiplexing ability of fluorescence microscopy is limited by the number of spectrally distinguishable fluorophores, a story in Nature Chemistry explained. The barcodes that scientists currently use have only three or four colors available, such as red, blue, or green. And sometimes those colors blur. This limits the number of objects scientists have been able to study in a cell sample at one time.

Multiplex Capability with 216 Readable Color Combinations

Using the new method, Yin was able to demonstrate 216 color combinations resulting from attaching just three colors to a DNA nanotube, the press release stated. With the new barcode, the combinations are almost limitless. This will significantly advance the ability to fluoresce more cellular structure than previously possible.

DNA origami works by programming a long strand of DNA to self-assemble by folding in on itself, the release stated. Shorter strands, called staples, help it to create predetermined forms. Researchers then attach fluorescent molecules to the desired spots on the now more structurally complex DNA nanostructures. In this way, they use origami technology to generate a large pool of barcodes out of only a few fluorescent molecules.

“We can essentially use DNA joints to assemble the nanostructures into long rods, and we can modify the rods with fluorescence at different locations,” declared Yin. “We then use these tiny rods to arrange the fluorescent spots into colorful barcodes. Basically now using three or four colors, we can have hundreds of different barcodes,” he observed in a story in The Harvard Crimson.

A New Tool in the Cellular Imaging—and In Situ Examination—Toolbox

“[The technique] holds great promise for using the method to study cells in their native environments,” Yin observed. Additionally, the technique is low-cost, easy to do, and more robust compared to current methods, according to Yin.

Pathologists and clinical laboratory managers will recognize the range of potential of this new technology, from developing targeted drug-delivery mechanisms to improving the scope of cellular and molecular activities scientists are able to observe at a disease site.

Economics and genetics meet in uneasy union

Use of population-genetic data to predict economic success sparks war of words.

10 October 2012 Corrected: 

  1. 12 October 2012
The United States has the right amount of genetic diversity to buoy its economy, claim economists.

picture: D. ACKER/BLOOMBERG VIA GETTY

“The invalid assumption that correlation implies cause is probably among the two or three most serious and common errors of human reasoning.” Evolutionary biologist Stephen Jay Gould was referring to purported links between genetics and an individual’s intelligence when he made this familiar complaint in his 1981 book The Mismeasure of Man

Fast-forward three decades, and leading geneticists and anthropologists are levelling a similar charge at economics researchers who claim that a country’s genetic diversity can predict the success of its economy. To critics, the economists’ paper seems to suggest that a country’s poverty could be the result of its citizens’ genetic make-up, and the paper is attracting charges of genetic determinism, and even racism. But the economists say that they have been misunderstood, and are merely using genetics as a proxy for other factors that can drive an economy, such as history and culture. The debate holds cautionary lessons for a nascent field that blends genetics with economics, sometimes called genoeconomics. The work could have real-world pay-offs, such as helping policy-makers to “reduce barriers to the flows of ideas and innovations across populations”, says Enrico Spolaore, an economist at Tufts University near Boston, Massachusetts, who has also used global genetic-diversity data in his research.

But the economists at the forefront of this field clearly need to be prepared for harsh scrutiny of their techniques and conclusions. At the centre of the storm is a 107-page paper by Oded Galor of Brown University in Providence, Rhode Island, and Quamrul Ashraf of Williams College in Williamstown, Massachusetts1. It has been peer-reviewed by economists and biologists, and will soon appear in American Economic Review, one of the most prestigious economics journals.

The paper argues that there are strong links between estimates of genetic diversity for 145 countries and per-capita incomes, even after accounting for myriad factors such as economic-based migration. High genetic diversity in a country’s population is linked with greater innovation, the paper says, because diverse populations have a greater range of cognitive abilities and styles. By contrast, low genetic diversity tends to produce societies with greater interpersonal trust, because there are fewer differences between populations. Countries with intermediate levels of diversity, such as the United States, balance these factors and have the most productive economies as a result, the economists conclude.

The manuscript had been circulating on the Internet for more than two years, garnering little attention outside economics — until last month, when Science published a summary of the paper in its section on new research in other journals. This sparked a sharp response from a long list of prominent scientists, including geneticist David Reich of Harvard Medical School in Boston, Massachusetts, and Harvard University palaeoanthropologist Daniel Lieberman in Cambridge.

In an open letter, the group said that it is worried about the political implications of the economists’ work: “the suggestion that an ideal level of genetic variation could foster economic growth and could even be engineered has the potential to be misused with frightening consequences to justify indefensible practices such as ethnic cleansing or genocide,” it said.

“Our study is not about a nature or nurture debate.”

The critics add that the economists made blunders such as treating the genetic diversity of different countries as independent data, when they are intrinsically linked by human migration and shared history. “It’s a misuse of data,” says Reich, which undermines the paper’s main conclusions. The populations of East Asian countries share a common genetic history, and cultural practices — but the former is not necessarily responsible for the latter. “Such haphazard methods and erroneous assumptions of statistical independence could equally find a genetic cause for the use of chopsticks,” the critics wrote.

They have missed the point, responds Galor, a prominent economist whose work examines the ancient origins of contemporary economic factors. “The entire criticism is based on a gross misinterpretation of our work and, in some respects, a superficial understanding of the empirical techniques employed,” he says. Galor and Ashraf told Nature that, far from claiming that genetic diversity directly influences economic development, they are using it as a proxy for immeasurable cultural, historical and biological factors that influence economies. “Our study is not about a nature or nurture debate,” says Ashraf. 

“It seems like the devil is in the interpretation more than the actual application of the statistics,” says Sohini Ramachandran, a population geneticist at Brown University who provided the genetic data for the study. She adds that Galor and Ashraf used estimates of genetic diversity that she and her colleagues specifically developed to overcome many of the confounding factors caused by the overlapping genetic and cultural histories of neighbouring countries.

Galor and Ashraf are not the first economists to use genetic-diversity data. Spolaore has also found that the differences in genetic diversity between countries can predict discrepancies in their level of economic development2. But he is clear that this is not necessarily a causal relationship:  “In my view it’s not genetic diversity itself that is responsible for this correlation,” he says. “A lot of this could be culture.”

Some say that the field needs a dose of rigour. Many studies linking genetic variation to economic traits make basic methodological errors, says Daniel Benjamin, a behavioural economist at Cornell University in Ithaca, New York. He is part of the Social Science Genetics Association Consortium, a group that brings together social scientists, epidemiologists and geneticists to improve such studies. Problems that medical geneticists have known about for years — such as those stemming from small sample sizes — crop up all too often when economists start to work with the data, he says.

For instance, while searching for genetic associations with factors such as happiness and income in a study of 2,349 Icelanders, Benjamin and his colleagues found a statistically significant association between educational attainment and a variant in a gene involved in breaking down a neurotransmitter molecule3. But the researchers could not replicate this association in three other population samples — a test for false positives that is standard practice in medical genetics — and the team now has reservations about the association. If the field is to develop fruitfully, “I think it’s essential for us to have geneticists involved”, says Benjamin. “We couldn’t do it without their help and insight.”

Corrected:

In the original text, we wrongly attributed to Enrico Spolaore the opinion that using genetic data in economics could help policy-makers to set immigration levels. He actually suggested that the work could reduce barriers to the flows of ideas and innovations across populations. The text has been amended to reflect that.

A research team from Massachusetts and Maryland used array-based transcriptome profiling to explore the genetic basis of a progressive neuromuscular condition called facioscapulohumeral muscular dystrophy, or FSHD. By testing bicep and deltoid muscle biopsy samples from dozens of individuals with FSHD and almost as many unaffected relatives of those subjects, the team tracked down hundreds of genes showing expression shifts in those with FSHD. Of those, 29 genes were differentially expressed in both bicep and deltoid muscle samples, the researchers report. And, they found expression levels at 15 genes could distinguish between bicep samples from those with or without the disease around 90 percent of the time in follow-up experiments. The accuracy was closer to 80 percent when classifying deltoid tissue based on expression of these genes. Those involved in the study say such a ‘molecular signature’ of FSHD could help in understanding the disease and in testing new treatments for it.

Abstract

Facioscapulohumeral muscular dystrophy (FSHD) is a progressive neuromuscular disorder caused by contractions of repetitive elements within the macrosatellite D4Z4 on chromosome 4q35. The pathophysiology of FSHD is unknown and, as a result, there is currently no effective treatment available for this disease. To better understand the pathophysiology of FSHD and develop mRNA-based biomarkers of affected muscles, we compared global analysis of gene expression in two distinct muscles obtained from a large number of FSHD subjects and their unaffected first-degree relatives. Gene expression in two muscle types was analyzed using GeneChip Gene 1.0 ST arrays: biceps, which typically shows an early and severe disease involvement; and deltoid, which is relatively uninvolved. For both muscle types, the expression differences were mild: using relaxed cutoffs for differential expression (fold change ≥1.2; nominal P value <0.01), we identified 191 and 110 genes differentially expressed between affected and control samples of biceps and deltoid muscle tissues, respectively, with 29 genes in common. Controlling for a false-discovery rate of <0.25 reduced the number of differentially expressed genes in biceps to 188 and in deltoid to 7. Expression levels of 15 genes altered in this study were used as a “molecular signature” in a validation study of an additional 26 subjects and predicted them as FSHD or control with 90% accuracy based on biceps and 80% accuracy based on deltoids.
