Distinguished members of the ISRLA Scientific Advisory Board (alphabetic)
Prof. Gil Atzmon
Gil Atzmon is Professor of Human Biology at Haifa University in Israel, where he runs the Laboratory of Genetics and Epigenetics of Aging and Longevity, and at Albert Einstein College of Medicine in New York. The foremost focus of Prof. Gil Atzmon’s entire research career has been the understanding of the association of the whole genome to disease, performance, health and longevity. Since 2001, he has focused on human genome and its impact on aging and longevity.
One of the highlights was the identification of several longevity associated genes. These genes, in association with large lipoprotein particle sizes, may protect from a variety of diseases such as dementia, diabetes, hypertension and coronary heart disease and may lead to potential new treatments. This observation led to screening of whole-genome utilizing high-throughput technology for genes associated with longevity.
In more recent years his focus has shifted to a new and challenging field involving the role of epigenetics in aging and longevity. Conducting a genome-wide cytosine methylation (HELPtag assay), he demonstrated (at conferences as an invited speaker in Orlando, Florida, 2013, New York, 2013, Beer Sheva, Israel, 2013, Brooklyn, NY, 2012, London, UK, 2012, Toronto, Canada, 2012, Bethesda, Maryland, 2012, Ventura, California, 2012, Santa Barbara, California, 2009, and as a presentation in ASHG Honolulu, Hawaii, 2009 and Santa Barbara, California, 2012) that there are epigenetic differences between centenarian and control samples, and that extremely old people share a common pattern of altered methylation that distinguishes them from young unrelated controls.
Using Sequenom’s MassARRAY technology, he validated the candidate methylated loci results from the whole genome methylation scan, and demonstrated expression differences of those candidates in normal aged versus long-lived individuals. Currently, Prof. Atzmon explores healthy longevity promoting loci by using one of the best models for successful healthy longevity – the Israeli Multi-ethnic Centenarian Study.
Prof. Haim Cohen
Prof. Haim Cohen, of the Mina and Everard Goodman Faculty of Life Sciences, Bar Ilan University, aims to elucidate the mechanism of themolecular regulation of aging.
In the Cohen Lab of Molecular Mechanism of Aging, his research team is investigating two major pathways that have been shown to regulate lifespan – caloric restriction (CR) and sirtuin deacetylases. Studies in model organisms show that the activity of the Sir2 family of NAD+-dependent protein deacetylases (sirtuins) is important in regulating lifespan in yeast, worms, and flies. Overexpression of Sir2 in these organisms can extend their lifespan by approximately 40%, and in some yeast and fly strains, Sir2 mediates the effect of CR on lifespan.
Moreover, Cohen’s team has recently shown that in mammals, SIRT1 and SIRT6, two of the human Sir2 homologues, are induced in multiple tissues upon CR, and mediate the protection of CR from cell death. In 2010, Cohen was awarded a roughly €2 million European Research Council (ERC) Starting Grant for a 5-year study entitled “SIRT6 Activation for Countering Age-Related Metabolic Diseases ( “SIRAID”).
These findings suggest that activation of sirtuins in mammals has the potential to mimic the beneficial influence of CR. In order to achieve this, Cohen’s lab has developed a mouse model known as MOSES (Mice Over-expreSsing Exogenous SIRT6), and found these mice to be protected against the pathological damage caused by obesity. When fed a diet to induce obesity, these mice accumulated significantly less fat, LDL-cholesterol, and triglycerides, and did not develop diabetes. These results demonstrate a protective role for SIRT6 against the metabolic consequences of the 21st century obesity epidemic and suggest a potentially beneficial effect of SIRT6 activation on age-related metabolic diseases. Cohen’s lab is currently focusing its efforts on identifying small molecules that can induce SIRT6 activity in order to develop drugs against age related metabolic diseases.

Prof. Yosef Gruenbaum
Professor at Hebrew University of Jerusalem. Department of Genetics.
Prof. Gruenbaum investigates Lamins, the nuclear intermediate filament (IF) proteins which are the major cytoskeleton component of animal nuclei. His lab is currently developing and using novel structural, genetic, cell biology and genomics approaches and state of the art equipment to uncover the structure of lamins and the pathways that they regulate. They have also established laminopathies models in C. elegans and use them to study why different mutations cause different diseases, including diseases associated with accelerated aging. It is hoped that these research efforts will generate an integrated view of the biology of lamins and their associated proteins.
Itamar Harel, PhD
Senior lecturer, the Hebrew University of Jerusalem at Givat Ram (http://harel-lab.com).
Dr. Harel was born in Israel, and grew in moshav Beit El’azari. He completed his BSc at Ben-Gurion University of the Negev (2002-2005), his PhD in developmental biology at the Weizmann Institute of Science (2006-2012), and his postdoctoral training in aging research at Stanford University (2013-2017). In spring of 2018, Itamar joined the Alexander Silberman Institute of Life Sciences, focusing on experimental biology of vertebrate aging and age-related diseases.
Aging is the primary risk factor for many human pathologies, such as cancer, diabetes, cardiovascular, and neurodegenerative diseases. Therefore, manipulating the aging rate itself, might allow us to postpone the onset of these devastating diseases, which will have a tremendous impact on human health. However, why and how we age remains a mystery, and defines one of the biggest challenges in biology.
For the past 20 years, the aging field has primarily focused on short-lived non-vertebrate model systems (such as yeast, worms, and flies), and our understanding about the aging process has increased exponentially. However, little is known about the unique aspects of vertebrates aging (humans included), mostly due-to their relatively long lifespan. To bridge this longstanding gap, Itamar is developing the shortest-lived vertebrate in captivity, the African turquoise killifish, as an exciting new platform for exploring mechanisms underlying vertebrate aging and age-related diseases.
Dr. Harel is the recipient of a number of prestigious fellowships, including the Damon Runyon, Human Frontier Science Program, and Rothschild Fellowships.

Valery Krizhanovsky, PhD
Incumbent of the Karl and Frances Korn Career Development Chair in Life Sciences. Department of Molecular Cell Biology, Weizmann Institute of Science
Dr. Valery Krizhanovsky’s research is focused on understanding of the role of cellular senescence in physiological and pathophysiological conditions.
Cellular senescence, a permanent state of cell cycle arrest accompanied by a complex phenotype that affects the microenvironment, is an essential mechanism that limits tumorigenesis and tissue damage. However, senescent cells accumulate in premalignant lesions, sites of tissue damage and in normal tissues during aging. If senescent cells are not cleared by the immune system, persist and accumulate in tissues, they have the potential to promote pathological conditions. Krizhanovsky lab studies how senescent cells affect cancer, aging and age-related diseases as well as embryonic development.
Dr. Krizhanovsky was one of the pioneers to study the role of cellular senescence in tissue damage and repair and the interaction of senescent cells with the immune system. Recently Krizhanovsky’s laboratory discovered a novel mechanism of interaction of senescent cells with other cells that regulates the immune surveillance of senescent cells. Research at Krizhanovsky’s laboratory showed presence of cellular senescence in the placenta; thus providing, together with other laboratories, the first evidence that senescence can play a role in embryonic development. Recent studies at the laboratory discovered mechanisms that regulate the viability of senescent cells. Inhibition of these pathways allowed elimination of senescent cells in vivo.
Current research at Krizhanovsky’s laboratory also focuses on: Cellular senescence in aging and age-related diseases; Interaction of senescent cells with the immune system; Cellular senescence in premalignant lesions and cancer.

Prof. Nir Barzilai
Prof. Nir Barzilai is the director of the Institute for Aging Research at the Albert Einstein College of Medicine and the Director of the Paul F. Glenn Center for the Biology of Human Aging Research and of the National Institutes of Health’s (NIH) Nathan Shock Centers of Excellence in the Basic Biology of Aging. He is the Ingeborg and Ira Leon Rennert Chair of Aging Research, professor in the Departments of Medicine and Genetics, and member of the Diabetes Research Center and of the Divisions of Endocrinology & Diabetes and Geriatrics.
Dr. Barzilai’s research interests are in the biology and genetics of aging. His focus is in the genetics of exceptional longevity, where his work has demonstrated that centenarians have protective genes that allow for the delay of aging and for the protection against age-related diseases. Taking full advantage of phenotypes, DNA, and cells from the Ashkenazi Jewish families with exceptional longevity and appropriate controls established at Albert Einstein, he has discovered underlying genomic differences associated with longevity.
The Longevity Genes Project (LGP) is a cross-sectional, on-going collection of blood and phenotype from families with centenarian proband. LonGenity is a longitudinal study of 1400 subjects, half offspring of parents with exceptional longevity, validating and following their aging in relationship to their genome. The second direction is focused on the metabolic decline of aging, and hypothesizes that the brain leads this decline. His lab has identified several central pathways that specifically alter body fat distribution and insulin action and secretion by intraventricular or hypothalamic administration of several peptides modulated by aging, including leptin, IGF-1, IGFBP3, and resveratrol.
He has received numerous grants, among them ones from the National Institute on Aging (NIA), American Federation for Aging Research, and the Ellison Medical Foundation. He has published over 200 peer-reviewed papers, reviews, and textbook chapters. He is an advisor to the NIH on multiple projects, initiatives, and study sections. He also serves on several editorial boards, is a reviewer for numerous other journals, and has been the recipient of numerous prestigious awards, including the Beeson Fellow for Aging Research, the Ellison Medical Foundation Senior Scholar in Aging Award, the Paul F. Glenn Foundation Award, the NIA Nathan Shock Award, and the 2010 Irving S. Wright Award of Distinction in Aging Research.
He is currently leading an international effort to approve drugs that can target aging. Targeting Aging with Metformin (TAME) is a specific study designed to prove the concept that multi-morbidities of aging can be delayed by metformin. He is currently working with the FDA to approve this approach to serve as a template for future efforts to delay aging and its diseases in humans.

Prof. Kunlin Jin
Department of Pharmacology and Neuroscience, Institute for Healthy Aging, University of North Texas, Texas, USA.
Dr. Jin received his M.D. degree in 1983 and Ph.D. degrees in Beijing University in 1991, where he also served as Assistant Professor of Molecular Biology in the Institute of Hematology at Beijing University. He came to the US in 1992 and worked as a postdoctoral fellow at the University of California, San Francisco and then at the University of Pittsburgh from 1995-96, when he was promoted to Instructor. In 1999 he accepted an offer to join the Buck Institute as an Assistant Scientist, and has then been promoted to Professor.
Dr. Jin is an author of over 155 peer-reviewed, original research papers．Dr. Jin’s recent papers have been published in competitive journals including the JCI, PNAS and Nature. More importantly, he has been a leader in several areas of investigation related to stroke, specifically the roles of adult neurogenesis and of endogenous neuroprotective proteins in regulating the brain’s response to ischemic injury and, most recently, the effect of aging on these processes. During his follow-up work, he made incredible findings that will profoundly influence the way we think about treatment of brain diseases by cell replacement using stem cells. Dr. Jin first discovered that brain injuries, including those caused by stroke and neurodegenerative diseases such as Alzheimer’s disease, can stimulate stem cells to generate new neurons in rodents as well as in human. In addition, his encouraging findings include how these neural stem cells can be manipulated by growth factors FGF-2, EGF, VEGF and SCF, even after intranasal administration. Dr. Jin’s discoveries make this a reality. His work has gained international recognition.
Dr. Jin is also Editor-in-Chief of Aging and Disease, and co-founder and chair ofInternational Society on Aging and Disease (ISOAD).
Alexey Olovnikov, PhD. Institute of Biochemical Physics, Russian Academy of Sciences.
In 1971, Olovnikov was the first to recognize the problem of the DNA end underreplication and to suggest the telomere hypothesis of cellular aging and the relationship of telomeres to cancer. In more details: 1) He predicted telomere DNA shortening during normal cell doublings and foretold the correlation between telomere length and the cell doublings potential, or Hayflick’s limit; 2) He predicted also the existence of a compensatory DNA polymerase responsible for maintenance of telomeres (now the compensatory enzyme is known as telomerase); 3) He supposed that cancer cells should have the same compensatory DNA polymerase (telomerase) as the germline cells, and assumed that this enzyme endows cancer cells, like the germline cells, with their immortality; 4) In addition, Olovnikov interpreted a circular form of bacteria’s genome as a means of protection of their DNA from shortening.
History has shown the validity of these basic predictions and explanations that were made by Olovnikov at the tip of a pen and essentially began a new area of research. Later, other researchers, for their experimental demonstration of how chromosomes are protected by telomeres and the enzyme telomerase, were awarded the Nobel Prize.
Currently, A.M. Olovnikov is elaborating a new “Chronographic Theory of Development, Aging, and Origin of Cancer”, positing a critical role of new hypothetical organelles – chronomeres and printomeres – in these processes. According to this theory, aging of a multicellular organism is caused by the stepwise programmed loss of chronomeres, whereas senescence of dividing cells is associated with the shortening and loss of printomeres. Both printomeres and chronomeres are small perichromosomal amplificates of the regulatory segments of chromosomal DNA, and they encode regulatory RNAs. Chronomeres are located in neurons of brain’s chronograph, or a specialized clock, which records the lived time in the form of nonrandom changes of body structures. According to the new theory, in the future, the key techniques to postpone organismal aging and to stop tumor growth could be: 1) a stopping of the pacemaker of the biochronograph mechanism, and 2) a forced regeneration, or re-synthesis, of chronomeres and printomeres.
