The ubiquitin system produces a protein that greatly restricts the development of cancerous tumors.
A new study by researchers at the Technion-Israel Institute of Technology could hold one key to control cancer cell growth and development. In a paper published in the April 9, 2015 edition of CELL, the team reports on the discovery of two cancer-suppressing proteins.

The research was conducted in the laboratory of Distinguished Professor Aaron Ciechanover, of the Technion Rappaport Faculty of Medicine. The team was led by research associate Dr. Yelena Kravtsova-Ivantsiv and , included additional research students and colleagues, as well as physicians from the Rambam, Carmel and Hadassah Medical Centers, who are studying tumors and their treatment.
The heretofore-undiscovered proteins were found during ongoing research on the ubiquitin system, an important and vital pathway in the life of the cell, which is responsible for the degradation of defective proteins that could damage the cell if not removed. The ubiquitin system tags these proteins and sends them for destruction in the cellular complex known as the proteasome. The system also removes functional and healthy proteins that are not needed anymore, thereby regulating the processes that these proteins control.
Usually, the proteins that reach the proteasome are completely broken down, but there are some exceptions, and the current line of research examined p105, a long precursor of a key regulator in the cell called NF-κB. It turns out that p105 can be broken down completely in certain cases following its tagging by ubiquitin, but in other cases it is only cut and shortened and becomes a protein called p50.
NF-κB has been identified as a link between inflammation and cancer. The hypothesis of the connection between inflammatory processes and cancer was first suggested in 1863 by German pathologist Rudolph Virchow, and has been confirmed over the years in a long series of studies. Ever since the discovery (nearly 30 years ago) of NF-κB, numerous articles have been published linking it to malignant transformation. It is involved in tumors of various organs (prostate, breast, lung, head and neck, large intestine, brain, etc.) in several parallel ways, including: inhibition of apoptosis (programmed cell death) normally eliminates transformed cells; acceleration of uncontrolled division of cancer cells; formation of new blood vessels (angiogenesis), which are vital to tumor growth; and increased resistance of cancerous cells to irradiation and chemotherapy.
The dramatic effect of these proteins on cancer growth: above the two tumors in the foreground (the control group) are tumors that express high levels of the proteins
As noted, the precursor p105 is “handled” by the ubiquitin system in one of two parallel and equally prevalent ways. It is either destroyed completely, or shortened and transformed to p50. The current research deciphers the decision-making mechanism that determines which process will be applied to the protein: when a ubiquitin system component called KPC1 is involved in the process and attaches ubiquitin to p105, the protein is shortened to become p50. When ubiquitination is mediated by another component of the system (and without KPC1), p105 is degraded.
The ubiquitin molecule within all living cells
The decision between these two options has significant implications on the cell, as the presence of high levels of KPC1 (which generates p50) and p50 (the product of the process) – with the accompanying disruption of the normal ratios between the processes – suppresses the malignant growth and apparently protects the healthy tissue. The current research was conducted on models of human tumors grown in mice, as well as on samples of human tumors, and a strong connection was discovered between the suppression of malignancy and the level of the two proteins, clearly indicating that the increased presence of KPC1 and/or p50 in the tissue can protect it from cancerous tumors.
Professor Ciechanover, who is also the president of the Israel Cancer Society, notes that many more years are required “to establish the research and gain a solid understanding of the mechanisms behind the suppression of the tumors. The development of a drug based on this discovery is a possibility, although not a certainty, and the road to such a drug is long and far from simple.”
Professor Ciechanover won the Nobel Prize in Chemistry in 2004 (jointly with Professors Avram Hershko – also from the Technion – and Irwin Rose, of the Fox Chase Cancer Center) for the discovery of the ubiquitin system. The current line of research is a continuation of that discovery.

Days after the Technion announced that a team led by Nobel Prize laureate Professor Aaron Ciechanover had discovered how proteins could be used to suppress cancer and control tumor growth and development, the institute revealed that it had entered into an exclusive agreement with India’s Sun Pharmaceuticals — the world’s fifth-largest specialty generic pharmaceutical company and India’s top pharmaceutical company.

Under the agreement, researchers from the Technion and Sun will conduct studies on how high concentrations of two proteins can protect tissue from tumors. A study published in the medical journal Cell this week discussed how the proteins can suppress malignancies.
Along with Ciechanover, the research team included Dr. Gila Maor and Professor Ofer Binah. In a statement, Ciechanover said that the research held a great deal of promise of an effective drug for treating cancer, “although this is not a certainty, and the road to such a drug is long and far from simple.”
The deal with Sun is just one of several R&D ventures between Israel and India, on both the business and government levels. So far, the two countries have signed seven bilateral economic and R&D agreements, including one that fosters joint projects on space travel and satellite development.
NYU and Technion to forge ‘groundbreaking’ partnership in cancer research
On Wednesday night, they announced a $9 million gift from philanthropists Laura and Isaac Perlmutter that will fund two major, joint research endeavors with potentially far-reaching impact in advancing cancer research. The joint program aims at attracting additional, world-class support from institutions and individuals who are dedicated to eradicating cancer through focused and efficient research, they said in a joint statement.
The first $3 million of the grant will finance six cancer-focused research projects to be conducted by teams spearheaded by co-investigators from both NYU and the Technion. The remaining $6 million will be used to establish a state-of-the-art research facility on Technion’s campus that will support these and other research projects and focus mainly on the emerging field of cancer metabolomics.
“NYU Langone and the Technion have a shared, longstanding commitment to advancing cancer research,” said Dr. Dafna Bar-Sagi, senior vice president and vice dean for science at the New York hospital, chief science officer at NYU School of Medicine and a principal architect of the NYU Langone-Technion partnership. “We are now at a great moment in our institutions’ illustrious histories, a point from which we can jointly leverage the talent and creativity of our researchers toward accelerating breakthroughs. The foresight and the generosity of the Perlmutters, particularly at this time of financial challenge in funding for basic research, will have tremendous impact.”
“Bringing together the unique expertise of researchers from both NYU and the Technion will hopefully enable us to overcome some of the most difficult challenges in treating cancer patients,” said Technion Prof. Aaron Ciechanover, the 2004 Nobel Prize Laureate in Chemistry and Distinguished Research Professor and head of the David and Janet Polak Cancer and Vascular Biology Research Center at the Technion Faculty of Medicine.
Renowned cancer biologist Dr. Benjamin Neel, an expert in the field of cell signal transduction, recently joined the Langone faculty as director of the Perlmutter Cancer Center, and Dr. Eyal Gottlieb, a world leader in cancer metabolism, has been recruited to lead the new research facility at the Technion funded by the Perlmutter gift. Neel will work closely with Ciechanover to lead the collaborative cancer research effort between the two institutions, they said.
In addition, Neel will oversee at NYU the building of world-class translational programs in immunotherapy, cancer genetics/targeted therapies and epigenetics, imaging, as well as expanded programs in clinical care, community outreach and supportive oncology.
New technology for early detection of stomach cancer
The innovative method, developed at the Technion, identifies persons at risk for developing stomach cancer and for detecting tumors at an earlier stage. The prestigious journal Gut, which published the research, notes that the detection method is quick, simple, inexpensive and non-invasive.
Innovative gastric cancer-detection technology
Innovative gastric cancer-detection technology developed by the Technion can be used for the early detection of stomach cancer and for identifying persons at risk for developing the disease. The new detection method, based on breath analysis, has significant advantages over the existing detection technology: Gut reports that the new method is quick, simple, inexpensive and non-invasive.
Gastric cancer is one of the most lethal forms of cancer and in most cases, its diagnosis involves an endoscopy (the insertion of a tube into the esophagus, requiring that the patient fast and receive an intravenous sedative). Treatment is aggressive chemotherapy, radiation and the full or partial removal of the stomach. The disease develops in a series of well-defined steps, but there’s currently no effective, reliable, and non-invasive screening test for picking up these changes early on. Thus, many people succumb to stomach cancer only because it was not diagnosed in time.
The new technology, developed by Prof. Hossam Haick of the Wolfson Faculty of Chemical Engineering, can be used to detect premalignant lesions at the earliest stage, when healthy cells start becoming cancerous.
The research, published in Gut as part of the doctoral thesis of Mr. Haitham Amal, was conducted in conjunction with a Latvian research group headed by Prof. Marcis Leja, based on the largest population sample ever in a trial of this type. 484 people participated in the trial, 99 of whom had already been diagnosed with stomach cancer. All the participants were tested for Helicobacter pylori, a bacterium known to increase the risk for stomach cancer, and two breath samples were taken from each person.
The first sample from each participant was analyzed using the GCMS technique, which measures volatile organic substances in exhaled breath. The researchers noted that GCMS technology cannot be used to detect stomach cancer because the testing is very expensive and requires lengthy processing times and considerable expertise to operate the equipment.
The second breath sample was tested using nanoarray analysis, the unique technology developed by Prof. Haick, combined with a pattern recognition algorithm.
The findings:
- Based on the concentrations of 8 specific substances (out of 130) in the oral cavity, the new technology can distinguish between three groups: gastric cancer patients, persons who have precancerous stomach lesions, and healthy individuals.
- The new technology accurately distinguishes between the various pre-malignant stages.
- The new technology can be used to identify persons at risk for developing gastric cancer.
- The diagnosis is accurate, regardless of other factors such as age, sex, smoking habits, alcohol consumption and the use of anti-oxidant drugs.
In short, the nano-array analysis method developed by Prof. Haick is accurate, sensitive technology that provides a simple and inexpensive alternative to existing tests (such as GCMS). This new technology offers early, effective detection of persons at risk for developing stomach cancer, without unnecessary invasive tests (endoscopy). In order to assess the accuracy and effectiveness of the new, a wide-scale clinical trial is currently under way in Europe, with thousands of participants who have cancerous or pre-cancerous tumors.
About Prof. Hossam Haick
Prof. Hossam Haick, who joined the senior staff at the Technion Wolfson Faculty of Chemical Engineering in 2006, has been working since that year on the development of innovative, non-invasive technology for detecting cancer and other diseases. This technology is based on an “electronic nose” – an apparatus capable of detecting illnesses by analyzing a patient’s exhaled breath.
Prof. Haick, a native of Nazareth, completed his Ph.D. studies at the Technion by the time he was 27 and went to the Weizmann Institute of Science in Rehovot and Caltech Institute of Technology in California. He returned to the Technion in 2006 and his research group was awarded one million euros in grants by the European Union, which was very impressed by his research into artificial olfactory systems. Today he heads a consortium that includes Siemens and several universities, research institutes and companies in Germany, Austria, Finland, Ireland, Latvia and Israel. Since joining the senior faculty in the Chemical Engineering Department in 2006, Prof. Haick has won dozens of awards, grants and international honors. These include the Marie Curie Excellence Grant, European Research Council (ERC) grant and the Bill & Melinda Gates Award. Prof. Haick was nominated to MIT’s list of the 35 leading young scientists worldwide, received the Knight of the Order of Academic Palms, from the French Government and won the Hershel Rich Technion Innovation Award (twice), as well as the Tenne Prize for Excellence in the Science of Nanotechnology. He has also been recognized for his outstanding teaching skills and is the recipient of the Yanai Prize for Academic Excellence. In 2014, at the initiative of the president of the Technion, Prof. Haick headed an MOOC (Massive Open Online Course) in nanotechnology and nano-sensors that had an enrollment of 42,000.
Early Warning of Cancer Metastasis
This month is Breast Cancer Awareness Month in Israel and around the world. Innovative technology developed at the Technion Faculty of Biomedical Engineering will enable the prediction of cancer metastasis after the appearance of breast cancer. The technology, whose efficacy has been proven in preliminary laboratory-trials, is entering into advanced testing using cells from patients undergoing surgery.
Assistant Professor Daphne Weihs recently achieved a research breakthrough: the unique technology that she developed – a biomechanical method for early detection of metastatic cancer – was approved by the Ethics Committee. This means that the technology that was found to be effective in tests on cell lines will advance to trials with tumor cells collected directly after surgery, in cooperation with Rambam Healthcare Campus.
According to Assistant Professor Weihs, the practical concept is that “during or immediately after a biopsy or surgery on a malignant tumor, the system will enable the medical team to quantitatively evaluate the likelihood of the presence or development of tumor metastases in other organs, and to propose which organ or organs are involved. Such knowledge will make it possible to act at a very early stage to identify and curb these metastases and, moreover, to prevent the primary tumor from metastasizing further.
Cancer is a general name for a wide family of diseases – more than 200 – whose common denominator is that the cell division rate becomes uncontrolled and the cells become immortal. In other words, the cancer mechanism disrupts the normal cell division process and converts it into “wild” and rapid division. Since the cells do not age and do not die, the original, primary tumor expands, invades and takes over more and more nearby tissue. In addition, apart from spreading to its immediate vicinity, a tumor that has become very aggressive “knows” how to send metastases to more distant tissues through the lymph and circulatory systems. Metastases (secondary tumors) are usually more dangerous than the primary tumor because it is difficult to identify them at their inception. When they are detected at an advanced stage, treating them medically is more complicated and the medical prognosis is typically not good.
“In fact, most cancer-related deaths are caused by metastases rather than by the primary tumor, and therefore vast resources are invested in developing methods for early detection of metastases,” explains Assistant Professor Daphne Weihs. “Early detection means timely and more effective treatment. The new approach that we are developing will enable early prediction of the likelihood of the formation of metastases and where in the body their development is probable. This prediction is based on identifying the biomechanics of the primary tumor cells, and does not require us to know the specific genetic makeup of the tumor.”

An innovative early disease detection system that uses the sense of smell is going mobile.
The NaNose breathalyzer technology developed by Professor Hossam Haick of the Technion will soon be installed in a mobile phone – to be called, appropriately, the SniffPhone. A tiny smell-sensitive sensor will be installed onto a phone add-on, and using specially designed software, the phone will be able to “smell” users’ breath to determine if they have cancer, among other serious diseases.
By identifying the special “odor” emitted by cancer cells, the NaNose system can detect the presence of tumors, both benign and malignant, more quickly, efficiently and cheaply than previously possible, said Haick.
“Current cancer diagnosis techniques are ineffective and impractical,” he said. NaNose technology, he said, “could facilitate faster therapeutic intervention, replacing expensive and time-consuming clinical follow-up that would eventually lead to the same intervention.”
According to research done by Haick’s team, the NaNose system has a 90 percent accuracy rate.
The smartphone device is just a vehicle to implement the NaNose technology that can be taken anywhere and used in any circumstances, including in rural areas of the developing world where bringing in sophisticated testing equipment is impossible.
The plan calls for a chip with NaNose technology to be installed in a device that is attached to a smartphone, and for an app to read the sensor data, analyzing it on the device or uploading it to the cloud for processing.
NaNose technology will be especially useful in battling lung cancer, said Haick. According to US government statistics, lung cancer kills more Americans annually than the next three most common cancers — colon, breast, and pancreatic — combined. The reason, doctors say, is because lung cancer is so difficult to detect. Currently, the only way to detect early-stage lung cancer is through an extensive process involving blood tests, biopsies, CT scans, ultrasound tests, and other procedures — and even then, detection is difficult.
“Mostly the patient arrives for diagnosis when the symptoms of the sickness have already begun to appear,” said Haick, describing the drawbacks in current detection protocols. “Months pass before a real analysis in completed. And the process requires complicated and expensive equipment such as CT and mammography imaging devices. Each machine costs millions of dollars, and ends up delivering rough, inaccurate results.”

The NaNose-based system, on the other hand, doesn’t require anything more than a patient’s breathing into the device in order to come up with an initial diagnosis. Lung cancer tumors produce chemicals called volatile organic compounds (VOCs), which easily evaporate into the air and produce a discernible scent profile. Haick’s NaNose chip detects the unique “signature” of VOCs in exhaled breath. In four out of five cases, the device differentiated between benign and malignant lung lesions and even different cancer subtypes.
The project is being funded by the European Commission, which has given the consortium developing it a six million euro grant. The developers include universities and research institutes from Germany, Austria, Finland, Ireland and Latvia, as well as Irish cell biology research firm Cellix, with the NaNose system the centerpiece of the technology. That Israeli-developed component will be delivered by an Israeli start-up called NanoVation-GS, a spinoff of the Technion. Professor Haick serves as the start-up’s Chief Science Officer.
“The SniffPhone is a winning solution. It will be made tinier and cheaper than disease detection solutions currently, consume little power, and most importantly, it will enable immediate and early diagnosis that is both accurate and non-invasive,” said Haick. “Early diagnosis can save lives, particularly in life-threatening diseases such as cancer.”
Anyone who knows a person in the midst of chemotherapy is aware that anti-cancer drugs often take a very harsh toll on the body. This is one reason scientists have been trying to develop improved means of drug delivery for years. Now, a Technion research team discovered a way to improve drug delivery to tumors using Nanostructured Porous Silicon (PSi) particles (instead of an IV drip), a method that’s emerging as a promising new platform for drug delivery. In the future, PSi could be used in cancer treatments, potentially offering an alternative to traditional chemotherapy, which is notorious for its agonizing side effects.
The silicon “carriers” used in this study to deliver chemotherapy drugs behave differently in cancerous tumors than they do in healthy tissues. Therefore, the findings could help scientists to design nano-carriers that deliver drugs to tumors, instead of treating patients with traditional, intravenous chemotherapy. However, it would take years to develop and apply this new type of drug delivery method, which would potentially be taken orally.

So far, these nano-silicon “containers” have been studied in vitro – outside of a living organism – rather than in an environment that behaves more closely to that of a tumor in a cancer patient’s body. The Technion research team looked at what happens to PSi particles when they’re injected into the area around the tumor in mice. The significant differences in the area around a cancerous growth and regular healthy tissue have been widely described and studied; however, the effect on these porous silicon “containers,” or carriers, was unknown until now.
Prof. Ester Segal of the Technion – Israel Institute of Technology, who led this joint study with the Massachusetts Institute of Technology (MIT) and the Harvard Medical School, said the team has “shown for the first time that bio-materials in general, and Nanostructured Porous Silicon in particular, behave differently when they are injected (or implanted) at the tumor micro-environment.”
Revolutionizing cancer treatments
Silicon materials could revolutionize treatments in a way that no existing drug delivery does. Prof. Segal tells NoCamels that the silicon containers “could deliver drugs over a long period of time – weeks or even months”, something no existing chemotherapeutic delivery mechanism can do currently.
Cancer cells
The special properties of these porous nano-silicon carriers lie in their large surface area, which can ferry many or large drug molecules. Additionally, due to their biodegradability they’re able to break down into harmless silicic acid, which is expelled through urination. They are also biocompatible, so they do not stimulate any inflammation or clotting. Another benefit to these nano-silicon containers is their versatility. They can be ingested, injected or implanted, and they can be designed to carry a wide range of dosage sizes. In the process of their study, lab members also developed an approach to determining how biomaterials will react in settings more similar to their eventual clinical purpose – treating cancer, for example.

In a separate study, Tel Aviv University scientists recently found a strategy that would stop brain tumor cell proliferation with similar nano-particles. “It is a basic, elegant mechanism and much less toxic than chemotherapy,” TAU’s Prof. Dan Peer said in a statement.
These works underline the importance of such studies in successfully developing bio-delivery materials that will have therapeutic benefits in the near future.
The ‘Magic Bullet’ of Chemotherapy

“Nano-skeletons’ (in red) delivered to human tissue infected by prostate cancer. The infected cells are colored in blue (PIP) and green (cytoplasmic); it is possible to see how the ‘nano-skeletons’ reach them
Florida native Dr. Beth Schoen, is part of a team developing a novel platform for delivering anti-cancerous drugs directly to its mark as part of her postdoctoral research at the Technion
Beth Schoen, born in Hollywood Florida, came to the Technion to conduct her postdoctoral research at age 26. In her very limited spare time she plays soccer for the leading all women’s soccer team – Maccabi Hadera – and studies Hebrew. “The Hebrew thing is no simple matter,” she confesses, “but I’m willing to make the effort, because it’s clear to me that Israel is where I want to live.”
Dr. Beth Schoen completed her undergraduate degree at the University of Florida, and her doctorate at Michigan State University in chemical engineering. “My doctoral studies focused on synthetic organic chemistry, particularly on the development of polymers with unique thermodynamic attributes especially resistant to high temperatures. These types of materials are used in part for the production of jet engine parts, body armor and Nomex (used for making fire-resistant gloves and overalls). One of our tasks was to create soft sheets that were not brittle, to be worn to be both bulletproof and fire resistant. It was a theoretical study, but as part of the process I also produced some of these polymers and tested them.”
Dr. Schoen planned to come to the Technion as part of her doctoral studies, but, she adds, “It didn’t work out, so I started to check where I could best fit in here in my future studies.” She decided to join Prof. Marcelle Machluf’s laboratory, at the Faculty of Biotechnology and Food Engineering, “I was eager to move from chemistry to biology and pursue cancer research in particular. I was very glad for the tremendous opportunity that Marcelle gave me in taking me on – perhaps it was because of my experience in nanomaterials and polymers.”
Prof. Marcelle Machluf’s research team consists of 17 female and 3 males students, researchers and technicians working on two main projects: (1) the development of scaffolds to rehabilitate damaged heart-tissue, and (2) the development of new technology to deliver drug treatment to damaged (sick) tissue (specifically related to cancer therapy). In an interview with her she focused on the second project.
“The current treatment for cancer involves radiotherapy and chemotherapy usually administered through intravenous infusion. The cancer drugs available are extremely effective, yet the way they are put to use in present day treatment, they also cause damage to healthy tissues. These are very potent drugs – they are intended to kill cancer cells – and on their way they also end up killing healthy ones.”
“The greatest damage is caused to rapidly dividing cells, which are similar to cancer cells. Hair follicle cells, for example, are a type of rapidly dividing cells and they damage easily from these types of treatment, which explains the hair loss in patients undergoing chemotherapy. Other side-effects include nausea and hearing loss, sometimes even leading to deafness. The drug Cisplatin for example, is a type of chemo drug used to treat various types of lung and breast cancers; some of its side-effects include damage to renal and immune system functioning, putting patients at risk to infections and diseases.”
These impediments are what fuel Prof. Machluf’s drive to develop a new drug delivery platforms capable of delivering anti-cancer drugs directly to the tumor without damaging healthy tissues on its way. “This is the top priority of cancer treatment: to develop a ‘magic bullet’ that target cancer cells,” explains Prof. Machluf. “And our new platform may be the solution to this great challenge.”
The new platform is based on ‘depleting’ specific cells – mesenchymal stem cells – so that there is nothing left of them save for the membrane. This membrane, called a ghost cells can be down sized to nano-vesicles, termed nano-ghosts, which can be loaded with any drug and delivered by injection directly into the blood stream. The immune system falls for the trap and does not recognize the ‘intruder,’ instead it treats these cells as if they were naturally part of the system and sends them to the afflicted area. On the way to their target they do not release the drug they are carrying and therefore do not do any damage to healthy tissues. Only upon reaching the malignant tissue, which they know how to identify, do they break down and secrete their contents at the site of the tumor cells.
This original idea was tested in a long series of experiments, and the results are very impressive: these nano-ghosts are in fact tumor selective, no matter the type of tumor. They ‘dash’ straight to the malignant tissue without emitting their drug on the way and without damaging healthy cells. Moreover, this unique ‘parcel’ increases the effectiveness of the treatment by ten-fold. Animal studies have shown that the employment of nano-ghosts for anti-cancer drug delivery have led to an 80% delay of prostate cancer – an unprecedented rate.
Still, there is a lot of work ahead, as Prof. Machluf’s research team works on improving the mechanism of this novel new platform: some of them are focusing on compatibility with specific drugs while others, like Dr. Beth Schoen, are concentrating on improving the nano-ghosts “This platform must be very precise,” explains Schoen. “It must be able to endure travelling through the entire human body, and release its contents only inside the tumor.”
The research is being carried out in collaboration with the Russell Berrie Nanotechnology Institute.
