Mission 4: Use of Systems Biology for Design of inhibitor of Galectins as Cancer Therapeutic – Strategy and Software

The following paper in Cells describes the discovery of protein interactors of endoglin, which is recruited to membranes at the TGF-β receptor complex upon TGF-β signaling. Interesting a carbohydrate binding protein, galectin-3, and an E3-ligase, TRIM21, were found to be unique interactors within this complex.

Abstract

Endoglin is a 180-kDa glycoprotein receptor primarily expressed by the vascular endothelium and involved in cardiovascular disease and cancer. Heterozygous mutations in the endoglin gene (ENG) cause hereditary hemorrhagic telangiectasia type 1, a vascular disease that presents with nasal and gastrointestinal bleeding, skin and mucosa telangiectases, and arteriovenous malformations in internal organs. A circulating form of endoglin (alias soluble endoglin, sEng), proteolytically released from the membrane-bound protein, has been observed in several inflammation-related pathological conditions and appears to contribute to endothelial dysfunction and cancer development through unknown mechanisms. Membrane-bound endoglin is an auxiliary component of the TGF-β receptor complex and the extracellular region of endoglin has been shown to interact with types I and II TGF-β receptors, as well as with BMP9 and BMP10 ligands, both members of the TGF-β family. To search for novel protein interactors, we screened a microarray containing over 9000 unique human proteins using recombinant sEng as bait. We find that sEng binds with high affinity, at least, to 22 new proteins. Among these, we validated the interaction of endoglin with galectin-3, a secreted member of the lectin family with capacity to bind membrane glycoproteins, and with tripartite motif-containing protein 21 (TRIM21), an E3 ubiquitin-protein ligase. Using human endothelial cells and Chinese hamster ovary cells, we showed that endoglin co-immunoprecipitates and co-localizes with galectin-3 or TRIM21. These results open new research avenues on endoglin function and regulation.

Endoglin is an auxiliary TGF-β co-receptor predominantly expressed in endothelial cells, which is involved in vascular development, repair, homeostasis, and disease [1,2,3,4]. Heterozygous mutations in the human ENDOGLIN gene (ENG) cause hereditary hemorrhagic telangiectasia (HHT) type 1, a vascular disease associated with nasal and gastrointestinal bleeds, telangiectases on skin and mucosa and arteriovenous malformations in the lung, liver, and brain [4,5,6]. The key role of endoglin in the vasculature is also illustrated by the fact that endoglin-KO mice die in utero due to defects in the vascular system [7]. Endoglin expression is markedly upregulated in proliferating endothelial cells involved in active angiogenesis, including the solid tumor neovasculature [8,9]. For this reason, endoglin has become a promising target for the antiangiogenic treatment of cancer [10,11,12]. Endoglin is also expressed in cancer cells where it can behave as both a tumor suppressor in prostate, breast, esophageal, and skin carcinomas [13,14,15,16] and a promoter of malignancy in melanoma and Ewing’s sarcoma [17]. Ectodomain shedding of membrane-bound endoglin may lead to a circulating form of the protein, also known as soluble endoglin (sEng) [18,19,20]. Increased levels of sEng have been found in several vascular-related pathologies, including preeclampsia, a disease of high prevalence in pregnant women which, if left untreated, can lead to serious and even fatal complications for both mother and baby [2,18,19,21]. Interestingly, several lines of evidence support a pathogenic role of sEng in the vascular system, including endothelial dysfunction, antiangiogenic activity, increased vascular permeability, inflammation-associated leukocyte adhesion and transmigration, and hypertension [18,22,23,24,25,26,27]. Because of its key role in vascular pathology, a large number of studies have addressed the structure and function of endoglin at the molecular level, in order to better understand its mechanism of action.

 Galectin-3 Interacts with Endoglin in Cells

Galectin-3 is a secreted member of the lectin family with the capacity to bind membrane glycoproteins like endoglin and is involved in the pathogenesis of many human diseases [52]. We confirmed the protein screen data for galectin-3, as evidenced by two-way co-immunoprecipitation of endoglin and galectin-3 upon co-transfection in CHO-K1 cells. As shown in Figure 1A, galectin-3 and endoglin were efficiently transfected, as demonstrated by Western blot analysis in total cell extracts. No background levels of endoglin were observed in control cells transfected with the empty vector (Ø). By contrast, galectin-3 could be detected in all samples but, as expected, showed an increased signal in cells transfected with the galectin-3 expression vector. Co-immunoprecipitation studies of these cell lysates showed that galectin-3 was present in endoglin immunoprecipitates (Figure 1B). Conversely, endoglin was also detected in galectin-3 immunoprecipitates (Figure 1C).

UniProtKB/Swiss-Prot Summary for TRIM21 Gene

E3 ubiquitin-protein ligase whose activity is dependent on E2 enzymes, UBE2D1, UBE2D2, UBE2E1 and UBE2E2. Forms a ubiquitin ligase complex in cooperation with the E2 UBE2D2 that is used not only for the ubiquitination of USP4 and IKBKB but also for its self-ubiquitination. Component of cullin-RING-based SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complexes such as SCF(SKP2)-like complexes. A TRIM21-containing SCF(SKP2)-like complex is shown to mediate ubiquitination of CDKN1B (‘Thr-187’ phosphorylated-form), thereby promoting its degradation by the proteasome. Monoubiquitinates IKBKB that will negatively regulates Tax-induced NF-kappa-B signaling. Negatively regulates IFN-beta production post-pathogen recognition by polyubiquitin-mediated degradation of IRF3. Mediates the ubiquitin-mediated proteasomal degradation of IgG1 heavy chain, which is linked to the VCP-mediated ER-associated degradation (ERAD) pathway. Promotes IRF8 ubiquitination, which enhanced the ability of IRF8 to stimulate cytokine genes transcription in macrophages. Plays a role in the regulation of the cell cycle progression. Enhances the decapping activity of DCP2. Exists as a ribonucleoprotein particle present in all mammalian cells studied and composed of a single polypeptide and one of four small RNA molecules. At least two isoforms are present in nucleated and red blood cells, and tissue specific differences in RO/SSA proteins have been identified. The common feature of these proteins is their ability to bind HY RNAs.2. Involved in the regulation of innate immunity and the inflammatory response in response to IFNG/IFN-gamma. Organizes autophagic machinery by serving as a platform for the assembly of ULK1, Beclin 1/BECN1 and ATG8 family members and recognizes specific autophagy targets, thus coordinating target recognition with assembly of the autophagic apparatus and initiation of autophagy. Acts as an autophagy receptor for the degradation of IRF3, hence attenuating type I interferon (IFN)-dependent immune responses (PubMed:26347139162978621631662716472766168805111802269418361920186413151884514219675099). Represses the innate antiviral response by facilitating the formation of the NMI-IFI35 complex through ‘Lys-63’-linked ubiquitination of NMI (PubMed:26342464). ( RO52_HUMAN,P19474 )

UniProtKB/Swiss-Prot Summary for TRIM21 Gene

E3 ubiquitin-protein ligase whose activity is dependent on E2 enzymes, UBE2D1, UBE2D2, UBE2E1 and UBE2E2. Forms a ubiquitin ligase complex in cooperation with the E2 UBE2D2 that is used not only for the ubiquitination of USP4 and IKBKB but also for its self-ubiquitination. Component of cullin-RING-based SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complexes such as SCF(SKP2)-like complexes. A TRIM21-containing SCF(SKP2)-like complex is shown to mediate ubiquitination of CDKN1B (‘Thr-187’ phosphorylated-form), thereby promoting its degradation by the proteasome. Monoubiquitinates IKBKB that will negatively regulates Tax-induced NF-kappa-B signaling. Negatively regulates IFN-beta production post-pathogen recognition by polyubiquitin-mediated degradation of IRF3. Mediates the ubiquitin-mediated proteasomal degradation of IgG1 heavy chain, which is linked to the VCP-mediated ER-associated degradation (ERAD) pathway. Promotes IRF8 ubiquitination, which enhanced the ability of IRF8 to stimulate cytokine genes transcription in macrophages. Plays a role in the regulation of the cell cycle progression. Enhances the decapping activity of DCP2. Exists as a ribonucleoprotein particle present in all mammalian cells studied and composed of a single polypeptide and one of four small RNA molecules. At least two isoforms are present in nucleated and red blood cells, and tissue specific differences in RO/SSA proteins have been identified. The common feature of these proteins is their ability to bind HY RNAs.2. Involved in the regulation of innate immunity and the inflammatory response in response to IFNG/IFN-gamma. Organizes autophagic machinery by serving as a platform for the assembly of ULK1, Beclin 1/BECN1 and ATG8 family members and recognizes specific autophagy targets, thus coordinating target recognition with assembly of the autophagic apparatus and initiation of autophagy. Acts as an autophagy receptor for the degradation of IRF3, hence attenuating type I interferon (IFN)-dependent immune responses (PubMed:26347139162978621631662716472766168805111802269418361920186413151884514219675099). Represses the innate antiviral response by facilitating the formation of the NMI-IFI35 complex through ‘Lys-63’-linked ubiquitination of NMI (PubMed:26342464). ( RO52_HUMAN,P19474 )

Abstract

Background

A systemic proinflammatory state plays a central role in the development of heart failure with preserved ejection fraction. Low‐level transcutaneous vagus nerve stimulation suppresses inflammation in humans. We conducted a sham‐controlled, double‐blind, randomized clinical trial to examine the effect of chronic low‐level transcutaneous vagus nerve stimulation on cardiac function, exercise capacity, and inflammation in patients with heart failure with preserved ejection fraction.

Methods and Results

Patients with heart failure with preserved ejection fraction and at least 2 additional comorbidities (obesity, diabetes, hypertension, or age ≥65 years) were randomized to either active (tragus) or sham (earlobe) low‐level transcutaneous vagus nerve stimulation (20 Hz, 1 mA below discomfort threshold), for 1 hour daily for 3 months. Echocardiography, 6‐minute walk test, quality of life, and serum cytokines were assessed at baseline and 3 months. Fifty‐two patients (mean age 70.4±9.2 years; 70% female) were included (active, n=26; sham, n=26). Baseline characteristics were balanced between the 2 arms. Adherence to the protocol of daily stimulation was >90% in both arms (P>0.05). While the early mitral inflow Doppler velocity to the early diastolic mitral annulus velocity ratio did not differ between groups, global longitudinal strain and tumor necrosis factor‐α levels at 3 months were significantly improved in the active compared with the sham arm (−18.6%±2.5% versus −16.0%±2.4%, P=0.002; 8.9±2.8 pg/mL versus 11.3±2.9 pg/mL, P=0.007, respectively). The reduction in tumor necrosis factor‐α levels correlated with global longitudinal strain improvement (r=−0.73, P=0.001). Quality of life was better in the active arm. No device‐related side effects were observed.

Conclusions

Neuromodulation with low‐level transcutaneous vagus nerve stimulation over 3 months resulted in a significant improvement in global longitudinal strain, inflammatory cytokines, and quality of life in patients with heart failure with preserved ejection fraction.

Perspectives on Nitric Oxide in Disease Mechanisms (Biomed e-Books Book 1)

by Margaret Baker PhD (Author) and 7 more 

5.0 out of 5 stars (5)

This book is a comprehensive review of Nitric Oxide, its discovery, function, and related opportunities for Targeted Therapy written by Experts, Authors, Writers: PhDs, MDs, MD/PhDs, PharmDs. Nitric oxide plays a wide variety of roles in cardiovascular system and acts as a central point for signal transduction pathway in endothelium. NITRIC OXIDE modulates vascular tone, fibrinolysis, blood pressure and proliferation of vascular smooth muscle cells. In the cardiovascular system disruption of NITRIC OXIDE pathways or alterations in NITRIC OXIDE production can result in predisposition to hypertension, hypercholesterolemia, diabetes mellitus, atherosclerosis and thrombosis. The essential role of NITRIC OXIDE is seen widely in organ function and in disease development. The role of NITRIC OXIDE covers the cardiovascular system, the acuity of sepsis and septic shock, gastrointestinal disease, renal disease, and neurological disorders. The final chapter is the essential role of NITRIC OXIDE in carcinogenesis. Therapeutic Targets to Clinical Applications: Pharmaco-therapy was developed and it represents methods to induce the production of Nitric Oxide and its enzymes for novel combination drug therapies.

This e-Book is a comprehensive review of recent Original Research on Cardiovascular Diseases: Causes, Risks and Management and related opportunities for Targeted Therapy written by Experts, Authors and Writers. The results of Original Research are gaining value added for the e-Reader by the Methodology of Curation. The e-Book’s articles have been published on the Open Access Online Scientific Journal, since April 2012. This e-Book includes a thorough evaluation of a rich source of research literature on the genomic influences, which may have variable strength in the biological causation of atherosclerosis, microvascular disease, plaque formation, not necessarily having expressing, except in a multivariable context that includes the environment, dietary factors, level of emotional stress, sleep habits, and the daily activities of living for affected individuals. The potential of genomics is carried in the DNA, copied to RNA, and this is most well studied in the micro RNAs (miRNA). The miRNA has been explored for the appearance in the circulation of specific miRNAs that might be associated with myocyte or endothelial cell injury, and they are also being used as targets for therapeutics by the creation of silencing RNAs (siRNA).

Regenerative and Translational Medicine: The Therapeutic Promise for Cardiovascular Diseases

by Justin D. Pearlman MD ME PhD MA FACC (Author) and 8 more 

This e-Book is a comprehensive review of recent Original Research on Cardiovascular Diseases: Causes, Risks and Management and related opportunities for Targeted Therapy written by Experts, Authors and Writers. The results of Original Research are gaining value added for the e-Reader by the Methodology of Curation. The e-Book’s articles have been published on the Open Access Online Scientific Journal, since April 2012. Part 1 is concerned with Posttranslational Modification of Proteins, vital for understanding cellular regulation and dysregulation. Part 2 is concerned with Translational Medical Therapeutics, the efficacy of medical and surgical decisions based on bringing the knowledge gained from the laboratory, and from clinical trials into the realm opf best practice. The time for this to occur in practice in the past has been through roughly a generation of physicians. That was in part related to the busy workload of physicians, and inability to easily access specialty literature as the volume and complexity increased. This had an effect of making access of a family to a primary care provider through a lifetime less likely than the period post WWII into the 1980s.

Pharmacological Agents in Treatment of Cardiovascular Diseases (Series A: Cardiovascular Diseases Book 5)

Pharmacological Agents in Treatment of Cardiovascular Diseases (Series A: Cardiovascular Diseases Book 5)

by Justin D. Pearlman (Author) and 2 more 

Pharmacologic therapy represents the dominant strategy for management of cardiovascular disease and consequences, deferring, complementing and often supplanting structural and functional interventions. The general strategy of medical management is to identify the biochemicals that control cardiovascular functions and responses, identify the consequences of push and pull (stimulation, potentiation, inhibition, blockade, counteractivity), check benefits and harm, systematically document the impact, both in population studies and in individuals, make wise choices, and optimize dosing. Medications mimic or modify natural biologic activities. Therefore genomics (the study of gene products, especially, messengers and receptors) and the cascade of signaling pathways that modulate responses identifies the myriad but theoretically finite possibilities for chemical intervention. Often there are many pathways that affect or are affected by cardiovascular disease, and multiple ways to promote desirable changes. Elucidation of the biochemical signal changes that correspond to or respond to cardiovascular disease conditions and treatments provides both biomarkers of patient health status and targets for therapy. The process of homeostasis resists change, including resisting desirable changes that aim to correct maladaptive biology. Thus medication to block an excess in heart rate and blood pressure, for example, leads to upregulation in the number and sensitivity of blocked receptors as well changes in activity of sibling pathways, which mitigate the impact of the blocking medication and promote rebound worsening of the primary concern if the medication gets interrupted. These issues influence combination therapy choices as well as concern about compliance with prescriptions. Therefore this guided tour of curated data relating to medical management of cardiovascular diseases draws from the human genome project to identify treatment opportunities, pathophysiology to understand the impact of disease and maladaptive responses, clinical disease and pharmaceutical classifications, and clinical trial results to clarify expected outcomes. Curation also addresses context, insight and opportunity. Review of all of the above by teams of experts leads to formulation of guidelines, but each patient is a unique individual for whom customized optimization offers further benefits. Optimal care requires understanding of all of the above to guide and optimize the offering and patient education for wise choices promoting optimal quality and quantity of life despite the presence of cardiovascular disease. Current health care priorities, current cardiovascular medication classification and offerings, and in depth review of the achievements and limitations of current and anticipated future pharmaceutical therapies for cardiovascular disease are. The current priorities adapt to cost benefit analysis of prevalent cardiovascular disorders, as limited resources are arguably best directed to where they will do the most good. The scope of that concern includes prevention as well as curtailment of severity of impairment, by improving out patient management, aiming at alleviated suffering and achieve sufficient quality of life to avoid expensive hospitalizations, interference with productivity, and shortened lifespan. Major categories of cardiovascular disease are reviewed in separate chapters, based on distinct pathways and therapeutic considerations. The closing chapter addresses adverse effects of therapy. In Part Two we focus on biomarkers – indicators of disease status. Chapter 15 presented recent new examples, such as BNP and high-sensitivity Troponin. Ch.16 addressed how the completion of the mapping of the human genome paves the way for identifying many more biomarkers. Ch.17 reviewed biomarker utility in various disease conditions. Ch.18 reviewed biomarker utility in acute disorders. Ch.19 on cholesterol, lipids, diet and Ch.20 on Inflammation.

Interventional Cardiology for Disease Diagnosis and Cardiac Surgery for Condition Treatment (Series A: Cardiovascular Diseases Book 6)

Interventional Cardiology for Disease Diagnosis and Cardiac Surgery for Condition Treatment (Series A: Cardiovascular Diseases Book 6)

by Justin D. Pearlman (Author) and 2 more 

In Cardiology, “Interventional” is reserved for procedures that directly produce physical changes. Surgical interventions for cardiovascular diseases include heart or heart and lung transplant, implantation of cardiac assist devices, shock devices and pacemakers, bypass grafts for coronary or other arteries, valve repairs or replacement, removal of plaque (endarterectomy), removal of tumors, and repair or palliation of injuries or of congenital anomalies. All of these interventions are continually studied and improved, with a major effort at minimizing the risk, reducing recovery time and reducing the size of entry scar, for example by use of video scopes instead of direct visualization, and mechanical devices and robotics instead of direct manual access. Interventional Cardiology refers to an often competing non-surgical approach in which access is limited to entry by vein or artery (catheterization). The two teams have joined forces to achieve a major success in replacing aortic valves by femoral artery access without opening the chest at all (TAVR), with on-going progress towards a similar approach to mitral valve replacement. This book addresses disease prevalence, personalized patient and doctor experiences with Cardiac Surgery, the role of transfusion, status of the MedTech market, and a review of major accomplishments from pathology, anesthesiology, radiology, cardiology and surgery. The contributions of specific groups, such as the Texas Heart Institute, the Dalio Institute at New York Presbyterian/Weill Cornell, the Cleveland Clinic, and the Scripps Institute are reviewed. Individual contributions from Eric Topol, Arthur Moss, Paul Zoll, Tim Wu, and Earl E. Bakken (Medtronic co-founder) are included. Discoveries in relevant biology, including ATP (the metabolic paycheck) and plasma metabolomics, and novel technologies such as tethered-liquid perfluorocabon surface biocoating to prevent clotting. Additional curations present views of cardiothoracic surgeons, vascular surgeons and of Catheterization lab interventionists. Business aspects are addressed by review of costs, prevalence, payment methods, prevention impact and business models. Decision support tools are also reviewed, and changes in guidelines. Voices of three Open Heart Surgery Survivors are included. Chapters 4-6 addressed clinical trial data in coronary disease, biomarkers of cardiovascular disorders, coagulation including top roles of nitric oxide, C-reative protein, protein C, aprotinin and thrombin. Chapters 7-8 covered amyloidosis, atherosclerosis, valve disease, flow reserve, atrial fibrillation and roles for advanced imaging. Chapters 9-10 covered unstable angina, transplants, and ventricular assist devices. Chapters 11-14 span interventions on the aorta, peripheral arteries, and coronary arteries, valve surgery and percutaneous valve repair or replacement, plus the growing role of prosthetics and repair by stem cells and tissue engineering. As catheter techniques evolved to compete with bypass surgery they progressed from balloon cracking of obstructive lesions (POBA=plain old balloon angioplasty) to placement of stents (wire fences). Surgeons sometimes use in-stent valves, and now devices analogous to in-stent valves can be placed by catheter for valve replacement in patients with too much co-morbidity to go through heart surgery. Aortic valve replacement by stent (TAVR) has had sufficient success to be considered for all patients who have sufficient impairment to merit intervention. The diameter is large, so a vascular surgeon participates in the arterial access and repair of the access site. Minimally invasive repair of abdominal aorta aneurysm: atherosclerosis offers potentially somewhat protective stiffening of the arterial wall, it can promote clots, athero-emboli, and failure of the remodeling can lead to an outward ballooning, or aneurysm, that promotes both clot formation and wall or lining tears or rupture, cause of sudden death.

Oncolytic Viruses in Cancer | Curing Melanoma and Beyond

Oncolytic viruses represent a powerful new technology, but so far an FDA-approved oncolytic (Imlygic) has only occurred in one area – melanoma and that what is in 2015. This panel involves some of the protagonists of this early success story.  They will explore why and how Imlygic became approved and its path to commercialization.  Yet, no other cancer indications exist for Imlygic, unlike the expansion of FDA-approved indication for immune checkpoint inhibitors to multiple cancers.  Why? Is there a limitation to what and which cancers can target?  Is the mode of administration a problem?

No other oncolytic virus therapy has been approved since 2015. Where will the next success story come from and why?  Will these therapies only be beneficial for skin cancers or other easily accessible cancers based on intratumoral delivery?

The panel will examine whether the preclinical models that have been developed for other cancer treatment modalities will be useful for oncolytic viruses.  It will also assess the extent pre-clinical development challenges have slowed the development of OVs. Moderator: Nino Chiocca, MD, PhD

Market Interest in Oncolytic Viruses | Calibrating

There are currently two oncolytic virus products on the market, one in the USA and one in China.  As of late 2020, there were 86 clinical trials 60 of which were in phase I with just 2 in Phase III the rest in Phase I/II or Phase II.   Although global sales of OVs are still in the ramp-up phase, some projections forecast OVs will be a $700 million market by 2026. This panel will address some of the major questions in this area:

What regulatory challenges will keep OVs from realizing their potential? Despite the promise of OVs for treating cancer only one has been approved in the US. Why has this been the case? Reasons such have viral tropism, viral species selection and delivery challenges have all been cited. However, these are also true of other modalities. Why then have oncolytic virus approaches not advanced faster and what are the primary challenges to be overcome?

  • Will these need to be combined with other agents to realize their full efficacy and how will that impact the market?
  • Why are these companies pursuing OVs while several others are taking a pass?

CAR-T | Lessons Learned | What’s Next

Few areas of potential cancer therapy have had the attention and excitement of CAR-T. This panel of leading executives, developers, and clinician-scientists will explore the current state of CAR-T and its future prospects. Among the questions to be addressed are:

  • Is CAR-T still an industry priority – i.e. are new investments being made by large companies? Are new companies being financed? What are the trends?
  • What have we learned from first-generation products, what can we expect from CAR-T going forward in novel targets, combinations, armored CAR’s and allogeneic treatment adoption?
  • Early trials showed remarkable overall survival and progression-free survival. What has been observed regarding how enduring these responses are?
  • Most of the approvals to date have targeted CD19, and most recently BCMA. What are the most common forms of relapses that have been observed?
  • Is there a consensus about what comes after these CD19 and BCMA trials as to additional targets in liquid tumors? How have dual-targeted approaches fared?

CAR-T | Solid Tumors Success | When?

The potential application of CAR-T in solid tumors will be a game-changer if it occurs. The panel explores the prospects of solid tumor success and what the barriers have been. Questions include:

  •  How would industry and investor strategy for CAR-T and solid tumors be characterized? Has it changed in the last couple of years?
  •  Does the lack of tumor antigen specificity in solid tumors mean that lessons from liquid tumor CAR-T constructs will not translate well and we have to start over?
  •  Whether due to antigen heterogeneity, a hostile tumor micro-environment, or other factors are some specific solid tumors more attractive opportunities than others for CAR-T therapy development?
  •  Given the many challenges that CAR-T faces in solid tumors, does the use of combination therapies from the start, for example, to mitigate TME effects, offer a more compelling opportunity.

GCT Manufacturing | Vector Production | Autologous and Allogeneic | Stem Cells | Supply Chain | Scalability & Management

The modes of GCT manufacturing have the potential of fundamentally reordering long-established roles and pathways. While complexity goes up the distance from discovery to deployment shrinks. With the likelihood of a total market for cell therapies to be over $48 billion by 2027,  groups of products are emerging.  Stem cell therapies are projected to be $28 billion by 2027 and non-stem cell therapies such as CAR-T are projected be $20 billion by 2027. The manufacturing challenges for these two large buckets are very different. Within the CAR-T realm there are diverging trends of autologous and allogeneic therapies and the demands on manufacturing infrastructure are very different. Questions for the panelists are:

  • Help us all understand the different manufacturing challenges for cell therapies. What are the trade-offs among storage cost, batch size, line changes in terms of production cost and what is the current state of scaling naïve and stem cell therapy treatment vs engineered cell therapies?
  • For cell and gene therapy what is the cost of Quality Assurance/Quality Control vs. production and how do you think this will trend over time based on your perspective on learning curves today?
  • Will point of care production become a reality? How will that change product development strategy for pharma and venture investors? What would be the regulatory implications for such products?
  • How close are allogeneic CAR-T cell therapies? If successful what are the market implications of allogenic CAR-T? What are the cost implications and rewards for developing allogeneic cell therapy treatments?

GCT | The China Juggernaut

China embraced gene and cell therapies early. The first China gene therapy clinical trial was in 1991. China approved the world’s first gene therapy product in 2003—Gendicine—an oncolytic adenovirus for the treatment of advanced head and neck cancer.  Driven by broad national strategy, China has become a hotbed of GCT development, ranking second in the world with more than 1,000 clinical trials either conducted or underway and thousands of related patents.  It has a booming GCT biotech sector, led by more than 45 local companies with growing IND pipelines.

In late 1990, a T cell-based immunotherapy, cytokine-induced killer (CIK) therapy became a popular modality in the clinic in China for tumor treatment.  In early 2010, Chinese researchers started to carry out domestic CAR T trials inspired by several important reports suggested the great antitumor function of CAR T cells. Now, China became the country with the most registered CAR T trials, CAR T therapy is flourishing in China.

The Chinese GCT ecosystem has increasingly rich local innovation and growing complement of development and investment partnerships – and also many subtleties.

This panel, consisting of leaders from the China GCT corporate, investor, research and entrepreneurial communities, will consider strategic questions on the growth of the gene and cell therapy industry in China, areas of greatest strength, evolving regulatory framework, early successes and products expected to reach the US and world market.

Benign Blood Disorders

Hemophilia has been and remains a hallmark indication for the CGT. Given its well-defined biology, larger market, and limited need for gene transfer to provide therapeutic benefit, it has been at the forefront of clinical development for years, however, product approval remains elusive. What are the main hurdles to this success? Contrary to many indications that CGT pursues no therapeutic options are available to patients, hemophiliacs have an increasing number of highly efficacious treatment options. How does the competitive landscape impact this field differently than other CGT fields? With many different players pursuing a gene therapy option for hemophilia, what are the main differentiators? Gene therapy for hemophilia seems compelling for low and middle-income countries, given the cost of currently available treatments; does your company see opportunities in this market?

Getting to the Heart of the Matter: Curing Genetic Cardiomyopathy

Christine Seidman, MD

  • Director, Cardiovascular Genetics Center, BWH
  • Smith Professor of Medicine & Genetics, HMS

The Voice of Dr. Seidman – Her abstract is cited below

The ultimate opportunity presented by discovering the genetic basis of human disease is accurate prediction and disease prevention. To enable this achievement, genetic insights must enable the identification of at-risk

individuals prior to end-stage disease manifestations and strategies that delay or prevent clinical expression. Genetic cardiomyopathies provide a paradigm for fulfilling these opportunities. Hypertrophic cardiomyopathy (HCM) is characterized by left ventricular hypertrophy, diastolic dysfunction with normal or enhanced systolic performance and a unique histopathology: myocyte hypertrophy, disarray and fibrosis. Dilated cardiomyopathy (DCM) exhibits enlarged ventricular volumes with depressed systolic performance and nonspecific histopathology. Both HCM and DCM are prevalent clinical conditions that increase risk for arrhythmias, sudden death, and heart failure. Today treatments for HCM and DCM focus on symptoms, but none prevent disease progression. Human molecular genetic studies demonstrated that these pathologies often result from dominant mutations in genes that encode protein components of the sarcomere, the contractile unit in striated muscles. These data combined with the emergence of molecular strategies to specifically modulate gene expression provide unparalleled opportunities to silence or correct mutant genes and to boost healthy gene expression in patients with genetic HCM and DCM. Many challenges remain, but the active and vital efforts of physicians, researchers, and patients are poised to ensure success.

Rare and Ultra Rare Diseases | GCT Breaks Through

One of the most innovative segments in all of healthcare is the development of GCT driven therapies for rare and ultra-rare diseases. Driven by a series of insights and tools and funded in part by disease focused foundations, philanthropists and abundant venture funding disease after disease is yielding to new GCT technology. These often become platforms to address more prevalent diseases. The goal of making these breakthroughs routine and affordable is challenged by a range of issues including clinical trial design and pricing.

  • What is driving the interest in rare diseases?
  • What are the biggest barriers to making breakthroughs ‘routine and affordable?’
  • What is the role of retrospective and prospective natural history studies in rare disease?  When does the expected value of retrospective disease history studies justify the cost?
  • Related to the first question, what is the FDA expecting as far as controls in clinical trials for rare diseases?  How does this impact the collection of natural history data?

Gene Editing | Achieving Therapeutic Mainstream

Gene editing was recognized by the Nobel Committee as “one of gene technology’s sharpest tools, having a revolutionary impact on life sciences.” Introduced in 2011, gene editing is used to modify DNA. It has applications across almost all categories of disease and is also being used in agriculture and public health.

Today’s panel is made up of pioneers who represent foundational aspects of gene editing.  They will discuss the movement of the technology into the therapeutic mainstream.

  • Successes in gene editing – lessons learned from late-stage assets (sickle cell, ophthalmology)
  • When to use what editing tool – pros and cons of traditional gene-editing v. base editing.  Is prime editing the future? Specific use cases for epigenetic editing.
  • When we reach widespread clinical use – role of off-target editing – is the risk real?  How will we mitigate? How practical is patient-specific off-target evaluation?

Common Blood Disorders | Gene Therapy

There are several dozen companies working to develop gene or cell therapies for Sickle Cell Disease, Beta Thalassemia, and  Fanconi Anemia. In some cases, there are enzyme replacement therapies that are deemed effective and safe. In other cases, the disease is only managed at best. This panel will address a number of questions that are particular to this class of genetic diseases:

  • What are the pros and cons of various strategies for treatment? There are AAV-based editing, non-viral delivery even oligonucleotide recruitment of endogenous editing/repair mechanisms. Which approaches are most appropriate for which disease?
  • How can companies increase the speed of recruitment for clinical trials when other treatments are available? What is the best approach to educate patients on a novel therapeutic?
  • How do we best address ethnic and socio-economic diversity to be more representative of the target patient population?
  • How long do we have to follow up with the patients from the scientific, patient’s community, and payer points of view? What are the current FDA and EMA guidelines for long-term follow-up?
  • Where are we with regards to surrogate endpoints and their application to clinically meaningful endpoints?
  • What are the emerging ethical dilemmas in pediatric gene therapy research? Are there challenges with informed consent and pediatric assent for trial participation?
  • Are there differences in reimbursement policies for these different blood disorders? Clearly durability of response is a big factor. Are there other considerations?

Oligonucleotide drugs have recently come into their own with approvals from companies such as Biogen, Alnylam, Novartis and others. This panel will address several questions:

How important is the delivery challenge for oligonucleotides? Are technological advancements emerging that will improve the delivery of oligonucleotides to the CNS or skeletal muscle after systemic administration?

  • Will oligonucleotides improve as a class that will make them even more effective?   Are further advancements in backbone chemistry anticipated, for example.
  • Will oligonucleotide based therapies blaze trails for follow-on gene therapy products?
  • Are small molecules a threat to oligonucleotide-based therapies?
  • Beyond exon skipping and knock-down mechanisms, what other roles will oligonucleotide-based therapies take mechanistically — can genes be activating oligonucleotides?  Is there a place for multiple mechanism oligonucleotide medicines?
  • Are there any advantages of RNAi-based oligonucleotides over ASOs, and if so for what use?

Rare and Ultra Rare Diseases | GCT Breaks Through

One of the most innovative segments in all of healthcare is the development of GCT driven therapies for rare and ultra-rare diseases. Driven by a series of insights and tools and funded in part by disease focused foundations, philanthropists and abundant venture funding disease after disease is yielding to new GCT technology. These often become platforms to address more prevalent diseases. The goal of making these breakthroughs routine and affordable is challenged by a range of issues including clinical trial design and pricing.

  • What is driving the interest in rare diseases?
  • What are the biggest barriers to making breakthroughs ‘routine and affordable?’
  • What is the role of retrospective and prospective natural history studies in rare disease?  When does the expected value of retrospective disease history studies justify the cost?
  • Related to the first question, what is the FDA expecting as far as controls in clinical trials for rare diseases?  How does this impact the collection of natural history data?

Gene Editing | Achieving Therapeutic Mainstream

Gene editing was recognized by the Nobel Committee as “one of gene technology’s sharpest tools, having a revolutionary impact on life sciences.” Introduced in 2011, gene editing is used to modify DNA. It has applications across almost all categories of disease and is also being used in agriculture and public health.

Today’s panel is made up of pioneers who represent foundational aspects of gene editing.  They will discuss the movement of the technology into the therapeutic mainstream.

  • Successes in gene editing – lessons learned from late-stage assets (sickle cell, ophthalmology)
  • When to use what editing tool – pros and cons of traditional gene-editing v. base editing.  Is prime editing the future? Specific use cases for epigenetic editing.
  • When we reach widespread clinical use – role of off-target editing – is the risk real?  How will we mitigate? How practical is patient-specific off-target evaluation?

Common Blood Disorders | Gene Therapy

There are several dozen companies working to develop gene or cell therapies for Sickle Cell Disease, Beta Thalassemia, and  Fanconi Anemia. In some cases, there are enzyme replacement therapies that are deemed effective and safe. In other cases, the disease is only managed at best. This panel will address a number of questions that are particular to this class of genetic diseases:

  • What are the pros and cons of various strategies for treatment? There are AAV-based editing, non-viral delivery even oligonucleotide recruitment of endogenous editing/repair mechanisms. Which approaches are most appropriate for which disease?
  • How can companies increase the speed of recruitment for clinical trials when other treatments are available? What is the best approach to educate patients on a novel therapeutic?
  • How do we best address ethnic and socio-economic diversity to be more representative of the target patient population?
  • How long do we have to follow up with the patients from the scientific, patient’s community, and payer points of view? What are the current FDA and EMA guidelines for long-term follow-up?
  • Where are we with regards to surrogate endpoints and their application to clinically meaningful endpoints?
  • What are the emerging ethical dilemmas in pediatric gene therapy research? Are there challenges with informed consent and pediatric assent for trial participation?
  • Are there differences in reimbursement policies for these different blood disorders? Clearly durability of response is a big factor. Are there other considerations?

Gene Expression | Modulating with Oligonucleotide-Based Therapies

Oligonucleotide drugs have recently come into their own with approvals from companies such as Biogen, Alnylam, Novartis and others. This panel will address several questions:

How important is the delivery challenge for oligonucleotides? Are technological advancements emerging that will improve the delivery of oligonucleotides to the CNS or skeletal muscle after systemic administration?

  • Will oligonucleotides improve as a class that will make them even more effective?   Are further advancements in backbone chemistry anticipated, for example.
  • Will oligonucleotide based therapies blaze trails for follow-on gene therapy products?
  • Are small molecules a threat to oligonucleotide-based therapies?
  • Beyond exon skipping and knock-down mechanisms, what other roles will oligonucleotide-based therapies take mechanistically — can genes be activating oligonucleotides?  Is there a place for multiple mechanism oligonucleotide medicines?
  • Are there any advantages of RNAi-based oligonucleotides over ASOs, and if so for what use?

Embryogenesis in Mechanical Womb

Reporter and Curator: Dr. Sudipta Saha, Ph.D.

A highly effective platforms for the ex utero culture of post-implantation mouse embryos have been developed in the present study by scientists of the Weizmann Institute of Science in Israel. The study was published in the journal Nature. They have grown more than 1,000 embryos in this way. This study enables the appropriate development of embryos from before gastrulation (embryonic day (E) 5.5) until the hindlimb formation stage (E11). Late gastrulating embryos (E7.5) are grown in three-dimensional rotating bottles, whereas extended culture from pre-gastrulation stages (E5.5 or E6.5) requires a combination of static and rotating bottle culture platforms.

At Day 11 of development more than halfway through a mouse pregnancy the researchers compared them to those developing in the uteruses of living mice and were found to be identical. Histological, molecular and single-cell RNA sequencing analyses confirm that the ex utero cultured embryos recapitulate in utero development precisely. The mouse embryos looked perfectly normal. All their organs developed as expected, along with their limbs and circulatory and nervous systems. Their tiny hearts were beating at a normal 170 beats per minute. But, the lab-grown embryos becomes too large to survive without a blood supply. They had a placenta and a yolk sack, but the nutrient solution that fed them through diffusion was no longer sufficient. So, a suitable mechanism for blood supply is required to be developed.

Till date the only way to study the development of tissues and organs is to turn to species like worms, frogs and flies that do not need a uterus, or to remove embryos from the uteruses of experimental animals at varying times, providing glimpses of development more like in snapshots than in live videos. This research will help scientists understand how mammals develop and how gene mutations, nutrients and environmental conditions may affect the fetus. This will allow researchers to mechanistically interrogate post-implantation morphogenesis and artificial embryogenesis in mammals. In the future it may be possible to develop a human embryo from fertilization to birth entirely outside the uterus. But the work may one day raise profound questions about whether other animals, even humans, should or could be cultured outside a living womb.

Precision Cardiology to Benefit from New Atlas of Cells of the Adult Human Heart

Reporters: Justin D. Pearlman, MD, PhD, FACC and Aviva Lev-Ari, PhD, RN

 

The Voice of Dr. Pearlman on potential clinical implications of the New Atlas:

 

Published on 9/24/2020 in Nature

Litviňuková, M., Talavera-López, C., Maatz, H. et al. Cells of the adult human heart. Nature (2020). https://doi.org/10.1038/s41586-020-2797-4

 

Abstract

Cardiovascular disease is the leading cause of death worldwide. Advanced insights into disease mechanisms and therapeutic strategies require deeper understanding of the healthy heart’s molecular processes. Knowledge of the full repertoire of cardiac cells and their gene expression profiles is a fundamental first step in this endeavor. Here, using state-of-the-art analyses of large-scale single-cell and nuclei transcriptomes, we characterise six anatomical adult heart regions. Our results highlight the cellular heterogeneity of cardiomyocytes, pericytes, and fibroblasts, revealing distinct atrial and ventricular subsets with diverse developmental origins and specialized properties. We define the complexity of the cardiac vasculature and its changes along the arterio-venous axis. In the immune compartment we identify cardiac resident macrophages with inflammatory and protective transcriptional signatures. Further, inference of cell-cell interactions highlight different macrophage-fibroblast-cardiomyocyte networks between atria and ventricles that are distinct from skeletal muscle. Our human cardiac cell atlas improves our understanding of the human heart and provides a healthy reference for future studies.

Studies have shown that regular physical activity can contribute to longer life and less risk for serious health problems, such as heart disease, type 2 diabetes, obesity and some cancers.  The Centers for Disease Control (CDC) continues to partner with national groups, states and communities to provide quality education around the physical activity.

An analysis, Adult Physical Inactivity Prevalence Maps by Race/Ethnicity, published on the CDC web site in January 2020 demonstrated that “all states and territories had more than 15 percent of adults who were physically inactive.” The analysis included state maps that used combined data from 2015 through 2018 with “noticeable differences in the prevalence of physical inactivity by race/ethnicity.” Physical inactivity is reported as “no leisure-time physical activity.”

Here are findings from their analysis:

  • The South (28.0%) had the highest prevalence of physical inactivity, followed by the Northeast (25.6%), Midwest (25.0%), and the West (20.5%).
  • In 7 states (Tennessee, Oklahoma, Louisiana, Alabama, Kentucky, Arkansas, and Mississippi), and 2 US territories (Puerto Rico, and Guam), 30% or more of adults were physically inactive.
  • In 4 states (Colorado, Washington, Utah, and Oregon) and the District of Columbia, 15% to less than 20% of adults were physically inactive.
  • In 24 states, 20% to less than 25% of adults were physically inactive.
  • In 15 states, 25% to less than 30% of adults were physically inactive.

More analysis showed:

  • Hispanics (31.7%) had the highest prevalence of physical inactivity, followed by non-Hispanic blacks (30.3%) and non-Hispanic whites (23.4%).
  • In the majority of states, non-Hispanic blacks and Hispanics had a significantly higher prevalence of inactivity than non-Hispanic whites.
  • 5 states and Puerto Rico had a physical inactivity prevalence of 30% or higher among non-Hispanic white adults.

Artificial Intelligence and Cardiovascular Disease

Reporter and Curator: Dr. Sudipta Saha, Ph.D.

3.3.18   Artificial Intelligence and Cardiovascular Disease, Volume 2 (Volume Two: Latest in Genomics Methodologies for Therapeutics: Gene Editing, NGS and BioInformatics, Simulations and the Genome Ontology), Part 2: CRISPR for Gene Editing and DNA Repair

Cardiology is a vast field that focuses on a large number of diseases specifically dealing with the heart, the circulatory system, and its functions. As such, similar symptomatologies and diagnostic features may be present in an individual, making it difficult for a doctor to easily isolate the actual heart-related problem. Consequently, the use of artificial intelligence aims to relieve doctors from this hurdle and extend better quality to patients. Results of screening tests such as echocardiograms, MRIs, or CT scans have long been proposed to be analyzed using more advanced techniques in the field of technology. As such, while artificial intelligence is not yet widely-used in clinical practice, it is seen as the future of healthcare.

The continuous development of the technological sector has enabled the industry to merge with medicine in order to create new integrated, reliable, and efficient methods of providing quality health care. One of the ongoing trends in cardiology at present is the proposed utilization of artificial intelligence (AI) in augmenting and extending the effectiveness of the cardiologist. This is because AI or machine-learning would allow for an accurate measure of patient functioning and diagnosis from the beginning up to the end of the therapeutic process. In particular, the use of artificial intelligence in cardiology aims to focus on research and development, clinical practice, and population health. Created to be an all-in-one mechanism in cardiac healthcare, AI technologies incorporate complex algorithms in determining relevant steps needed for a successful diagnosis and treatment. The role of artificial intelligence specifically extends to the identification of novel drug therapies, disease stratification or statistics, continuous remote monitoring and diagnostics, integration of multi-omic data, and extension of physician effectivity and efficiency.

Artificial intelligence – specifically a branch of it called machine learning – is being used in medicine to help with diagnosis. Computers might, for example, be better at interpreting heart scans. Computers can be ‘trained’ to make these predictions. This is done by feeding the computer information from hundreds or thousands of patients, plus instructions (an algorithm) on how to use that information. This information is heart scans, genetic and other test results, and how long each patient survived. These scans are in exquisite detail and the computer may be able to spot differences that are beyond human perception. It can also combine information from many different tests to give as accurate a picture as possible. The computer starts to work out which factors affected the patients’ outlook, so it can make predictions about other patients.

In current medical practice, doctors will use risk scores to make treatment decisions for their cardiac patients. These are based on a series of variables like weight, age and lifestyle. However, they do not always have the desired levels of accuracy. A particular example of the use of artificial examination in cardiology is the experimental study on heart disease patients, published in 2017. The researchers utilized cardiac MRI-based algorithms coupled with a 3D systolic cardiac motion pattern to accurately predict the health outcomes of patients with pulmonary hypertension. The experiment proved to be successful, with the technology being able to pick-up 30,000 points within the heart activity of 250 patients. With the success of the aforementioned study, as well as the promise of other researches on artificial intelligence, cardiology is seemingly moving towards a more technological practice.

One study was conducted in Finland where researchers enrolled 950 patients complaining of chest pain, who underwent the centre’s usual scanning protocol to check for coronary artery disease. Their outcomes were tracked for six years following their initial scans, over the course of which 24 of the patients had heart attacks and 49 died from all causes. The patients first underwent a coronary computed tomography angiography (CCTA) scan, which yielded 58 pieces of data on the presence of coronary plaque, vessel narrowing and calcification. Patients whose scans were suggestive of disease underwent a positron emission tomography (PET) scan which produced 17 variables on blood flow. Ten clinical variables were also obtained from medical records including sex, age, smoking status and diabetes. These 85 variables were then entered into an artificial intelligence (AI) programme called LogitBoost. The AI repeatedly analysed the imaging variables, and was able to learn how the imaging data interacted and identify the patterns which preceded death and heart attack with over 90% accuracy. The predictive performance using the ten clinical variables alone was modest, with an accuracy of 90%. When PET scan data was added, accuracy increased to 92.5%. The predictive performance increased significantly when CCTA scan data was added to clinical and PET data, with accuracy of 95.4%.

Another study findings showed that applying artificial intelligence (AI) to the electrocardiogram (ECG) enables early detection of left ventricular dysfunction and can identify individuals at increased risk for its development in the future. Asymptomatic left ventricular dysfunction (ALVD) is characterised by the presence of a weak heart pump with a risk of overt heart failure. It is present in three to six percent of the general population and is associated with reduced quality of life and longevity. However, it is treatable when found. Currently, there is no inexpensive, noninvasive, painless screening tool for ALVD available for diagnostic use. When tested on an independent set of 52,870 patients, the network model yielded values for the area under the curve, sensitivity, specificity, and accuracy of 0.93, 86.3 percent, 85.7 percent, and 85.7 percent, respectively. Furthermore, in patients without ventricular dysfunction, those with a positive AI screen were at four times the risk of developing future ventricular dysfunction compared with those with a negative screen.

In recent years, the analysis of big data database combined with computer deep learning has gradually played an important role in biomedical technology. For a large number of medical record data analysis, image analysis, single nucleotide polymorphism difference analysis, etc., all relevant research on the development and application of artificial intelligence can be observed extensively. For clinical indication, patients may receive a variety of cardiovascular routine examination and treatments, such as: cardiac ultrasound, multi-path ECG, cardiovascular and peripheral angiography, intravascular ultrasound and optical coherence tomography, electrical physiology, etc. By using artificial intelligence deep learning system, the investigators hope to not only improve the diagnostic rate and also gain more accurately predict the patient’s recovery, improve medical quality in the near future.

The primary issue about using artificial intelligence in cardiology, or in any field of medicine for that matter, is the ethical issues that it brings about. Physicians and healthcare professionals prior to their practice swear to the Hippocratic Oath—a promise to do their best for the welfare and betterment of their patients. Many physicians have argued that the use of artificial intelligence in medicine breaks the Hippocratic Oath since patients are technically left under the care of machines than of doctors. Furthermore, as machines may also malfunction, the safety of patients is also on the line at all times. As such, while medical practitioners see the promise of artificial technology, they are also heavily constricted about its use, safety, and appropriateness in medical practice.

Issues and challenges faced by technological innovations in cardiology are overpowered by current researches aiming to make artificial intelligence easily accessible and available for all. With that in mind, various projects are currently under study. For example, the use of wearable AI technology aims to develop a mechanism by which patients and doctors could easily access and monitor cardiac activity remotely. An ideal instrument for monitoring, wearable AI technology ensures real-time updates, monitoring, and evaluation. Another direction of cardiology in AI technology is the use of technology to record and validate empirical data to further analyze symptomatology, biomarkers, and treatment effectiveness. With AI technology, researchers in cardiology are aiming to simplify and expand the scope of knowledge on the field for better patient care and treatment outcomes.

@Cleveland Clinic – Serial measurements of high-sensitivity C-reactive protein (hsCRP) post acute coronary syndrome (ACS) may help identify patients at higher risk for morbidity and mortality

 

Reporter: Aviva Lev-Ari, PhD, RN

 

Original Investigation
March 6, 2019

Association of Initial and Serial C-Reactive Protein Levels With Adverse Cardiovascular Events and Death After Acute Coronary Syndrome, A Secondary Analysis of the VISTA-16 Trial

Key Points

Question  Are initial and serial increases in high-sensitivity C-reactive protein levels after acute coronary syndrome in medically optimized patients associated with increased risk of a major cardiac event, cardiovascular death, and all-cause death?

Findings  In this secondary analysis of the VISTA-16 randomized clinical trial that included 5145 patients, baseline and longitudinal high-sensitivity C-reactive protein levels were independently associated with increased risk of a major adverse cardiac event, cardiovascular death, and all-cause death during the 16-week follow-up.

Meaning  Monitoring high-sensitivity C-reactive protein levels in patients after acute coronary syndrome may help better identify patients at greater risk for recurrent cardiovascular events or death.

Abstract

Importance  Higher baseline high-sensitivity C-reactive protein (hsCRP) levels after an acute coronary syndrome (ACS) are associated with adverse cardiovascular outcomes. The usefulness of serial hsCRP measurements for risk stratifying patients after ACS is not well characterized.

Objective  To assess whether longitudinal increases in hsCRP measurements during the 16 weeks after ACS are independently associated with a greater risk of a major adverse cardiac event (MACE), all-cause death, and cardiovascular death.

Results  Among 4257 patients in this study, 3141 (73.8%) were men and the mean age was 60.3 years (interquartile range [IQR], 53.5-67.8 years). The median 16-week low-density lipoprotein cholesterol level was 64.9 mg/dL (IQR, 50.3-82.3 mg/dL), and the median hsCRP level was 2.4 mg/L (IQR, 1.1-5.2 mg/L). On multivariable analysis, higher baseline hsCRP level (hazard ratio [HR], 1.36 [95% CI, 1.13-1.63]; P = .001) and higher longitudinal hsCRP level (HR, 1.15 [95% CI, 1.09-1.21]; P < .001) were independently associated with MACE. Similar significant and independent associations were shown between baseline and longitudinal hsCRP levels and cardiovascular death (baseline: HR, 1.61 per SD [95% CI, 1.07-2.41], P = .02; longitudinal: HR, 1.26 per SD [95% CI, 1.19-1.34], P < .001) and between baseline and longitudinal hsCRP levels and all-cause death (baseline: HR, 1.58 per SD [95% CI, 1.07-2.35], P = .02; longitudinal: HR, 1.25 per SD [95% CI, 1.18-1.32], P < .001).

Conclusions and Relevance  Initial and subsequent increases in hsCRP levels during 16 weeks after ACS were associated with a greater risk of the combined MACE end point, cardiovascular death, and all-cause death despite established background therapies. Serial measurements of hsCRP during clinical follow-up after ACS may help to identify patients at higher risk for mortality and morbidity.

Inflammation’s role in residual risk

Residual risk of cardiovascular events or death remains high following ACS, despite coronary revascularization and optimal guideline-directed treatment with antiplatelet and LDL cholesterol-lowering agents. Inflammation is thought to drive this risk, but no effective treatment for such inflammation is commercially available. The secretory phospholipase A2 inhibitor varespladib was developed to meet this need, and it was evaluated in VISTA-16.

VISTA-16 was an international, multicenter clinical trial that randomized 5,145 patients in a double-blind manner to varespladib or placebo on a background of atorvastatin treatment within 96 hours of presentation with ACS. The trial was terminated early due to futility and likely harm from the drug, which was subsequently pulled from development.

Implications for practice

The association of increasing CRP levels with residual cardiovascular risk may prompt more intensive treatment to lower this risk. In particular, a secondary analysis showed that use of antiplatelet agents (clopidogrel, ticlopidine and prasugrel) was associated with stable or decreasing hsCRP levels.

“Monitoring not only lipids but also hsCRP after ACS may help us better identify patients at increased risk for recurrent cardiovascular events or death,” notes Dr. Puri. “High or increasing CRP levels could be an indication to optimize dual antiplatelet therapy post-ACS, along with high-intensity statin therapy (and possibly PCSK9 inhibitors) and antihypertensive therapy, in addition to instituting measures that are globally beneficial, such as dietary modifications and cardiac rehabilitation/exercise.”

In the absence of agonist (A), GPCRs are mainly in the low affinity state (R). After agonist binding, the receptor is activated in the high affinity state (R*), and the agonist-GPCR-G protein complex is formed. GTP replaces GDP in Gα. After that the G protein dissociates into the Gα subunit and the Gβγ heterodimer, which then activate several effector proteins. The built-in GTPase activity of the Gα subunit cleaves the terminal phosphate group of GTP, and the GDP bound Gα subunit reassociates with Gβγ heterodimer. This results in the deactivation of both Gα and Gβγ. The G protein cycle returns to the basal state. RGS, regulator of G protein signalling.”/></a>

cyclic AMP (cAMP) signaling to the effector Protein Kinase A (PKA)

from https://courses.washington.edu/conj/gprotein/cyclicamp.htm

Cyclic AMP is an important second messenger. It forms, as shown, when the membrane enzyme adenylyl cyclase is activated (as indicated, by the alpha subunit of a G protein).

 

The cyclic AMP then goes on the activate specific proteins. Some ion channels, for example, are gated by cyclic AMP. But an especially important protein activated by cyclic AMP is protein kinase A, which goes on the phosphorylate certain cellular proteins. The scheme below shows how cyclic AMP activates protein kinase A.

Additional New Studies on Regulation of the Beta 2 Adrenergic Receptor

We had discussed regulation of the G protein coupled beta 2 adrenergic receptor by the B-AR receptor kinase (BARK)/B arrestin system which uncouples and desensitizes the receptor from its G protein system.  In an article by Xiangyu Liu in Science in 2019, the authors describe another type of allosteric modulation (this time a POSITIVE allosteric modulation) in the intracellular loop 2.  See below:

Positive reinforcement in a GPCR

Many drug discovery efforts focus on G protein–coupled receptors (GPCRs), a class of receptors that regulate many physiological processes. An exemplar is the β2-adrenergic receptor (β2AR), which is targeted by both blockers and agonists to treat cardiovascular and respiratory diseases. Most GPCR drugs target the primary (orthosteric) ligand binding site, but binding at allosteric sites can modulate activation. Because such allosteric sites are less conserved, they could possibly be targeted more specifically. Liu et al. report the crystal structure of β2AR bound to both an orthosteric agonist and a positive allosteric modulator that increases receptor activity. The structure suggests why the modulator compound is selective for β2AR over the closely related β1AR. Furthermore, the structure reveals that the modulator acts by enhancing orthosteric agonist binding and stabilizing the active conformation of the receptor.

Abstract

Drugs targeting the orthosteric, primary binding site of G protein–coupled receptors are the most common therapeutics. Allosteric binding sites, elsewhere on the receptors, are less well-defined, and so less exploited clinically. We report the crystal structure of the prototypic β2-adrenergic receptor in complex with an orthosteric agonist and compound-6FA, a positive allosteric modulator of this receptor. It binds on the receptor’s inner surface in a pocket created by intracellular loop 2 and transmembrane segments 3 and 4, stabilizing the loop in an α-helical conformation required to engage the G protein. Structural comparison explains the selectivity of the compound for β2– over the β1-adrenergic receptor. Diversity in location, mechanism, and selectivity of allosteric ligands provides potential to expand the range of receptor drugs.

 

Recent structures of GPCRs bound to allosteric modulators have revealed that receptor surfaces are decorated with diverse cavities and crevices that may serve as allosteric modulatory sites (1). This substantiates the notion that GPCRs are structurally plastic and can be modulated by a variety of allosteric ligands through distinct mechanisms (2-7). Most of these structures have been solved with negative allosteric modulators (NAMs), which stabilize receptors in their inactive states (1). To date, only a single structure of an active GPCR bound to a small-molecule positive allosteric modulator (PAM) has been reported, namely, the M2 muscarinic acetylcholine receptor with LY2119620 (8). Thus, mechanisms of PAMs and their potential binding sites remain largely unexplored.

Allosteric sites may not face the same evolutionary pressure as do orthosteric sites, and thus are more divergent across subtypes within a receptor family (2426). Therefore, allosteric sites may provide a greater source of specificity for targeting GPCRs.

Additional information on Nitric Oxide as a Cellular Signal

Nitric oxide is actually a free radical and can react with other free radicals, resulting in a very short half life (only a few seconds) and so in the body is produced locally to its site of action (i.e. in endothelial cells surrounding the vascular smooth muscle, in nerve cells). In the late 1970s, Dr. Robert Furchgott observed that acetylcholine released a substance that produced vascular relaxation, but only when the endothelium was intact. This observation opened this field of research and eventually led to his receiving a Nobel prize. Initially, Furchgott called this substance endothelium-derived relaxing factor (EDRF), but by the mid-1980s he and others identified this substance as being NO.

Nitric oxide is produced from metabolism of endogenous substances like L-arginine, catalyzed by one of three isoforms of nitric oxide synthase (for link to a good article see here) or release from exogenous compounds like drugs used to treat angina pectoris like amyl nitrate or drugs used for hypertension such as sodium nitroprusside.

Nitric oxide is implicated in many pathologic processes as well.  Nitric oxide post translational modifications have been attributed to nitric oxide’s role in pathology however, although the general mechanism by which nitric oxide exerts its physiological effects is by stimulation of soluble guanylate cyclase to produce cGMP, these post translational modifications can act as a cellular signal as well.  For more information of NO pathologic effects and how NO induced post translational modifications can act as a cellular signal see the following:
