Identifying molecular hallmarks of aging to guide the development of anti-aging therapies.

Lab focus

Why do we age? Despite more than 30 years of research in the genetics of aging and a much longer history interrogating the process more generally, we still don’t know the answer to this basic question. There has been some success in manipulating the lifespan of simple laboratory organisms and, to a lesser extent, mammalian systems such as the laboratory mouse. However, true insight into the mechanisms which modulate longevity elude us at present. Otherwise we would be able to make our favorite model systems with lifespans of a few weeks live for not just a month or two but potentially decades, all while remaining youthful and healthy. The Melov lab takes a multidisciplinary geroscience approach to better understand the core mechanisms that drive aging. This includes a heavy reliance on multiple model systems, including invertebrate models, mammalian models (the laboratory mouse), human cell lines and tissues, and state-of-the-art genomic technologies that rely on heavy computational methods to better understand how cells and tissues change with age and/or pharmacological intervention.

Why it matters

We must constantly question our own models and data to gain genuine insights into the mechanisms that drive the degenerative changes arising from intrinsic aging processes. A key philosophy of the lab is that it is not enough to enhance healthspan through simple dietary or lifestyle interventions. We argue that such approaches merely fine-tune an organism to survive in its current environment. While worthwhile for generally improving health, such paradigms will do little to uncover the key drivers that limit lifespan. In contrast, we hope to develop novel multidisciplinary approaches in geroscience to develop therapeutics that are effective in reducing or ameliorating the cellular damage arising from endogenous aging processes. Such an approach will pay massive dividends to improve the health and longevity of a rapidly aging world.
Efforts to extend healthspan by delaying the aging process are moving from ‘impossible’ to ‘inevitable.’ The Buck Institute is uniquely positioned to play a pivotal role in this new area of medicine.

Simon Melov, PhD

The Melov lab is pleased to acknowledge the generous support of the following major funders:

Dr. Melov was the third faculty hire at the Buck Institute when it opened its doors in 1999 and currently serves as co-director of the Institute’s Mouse Phenotyping and Single-Cell Biology cores. An Australian, Dr. Melov obtained his bachelor’s degree in human genetics from the University of New South Wales in Sydney, Australia, and then completed his PhD in biochemistry at Imperial College London in the United Kingdom. He carried out postdoctoral studies on the genetics of aging at the University of Colorado, Boulder, and on mitochondrial disease at Emory University in the Department of Molecular Medicine. He also holds adjunct appointments at the Andrus College of Gerontology, University of Southern California, and Dominican University of California in San Rafael.

Dr. Melov is facile in multiple aspects of aging biology, which is now termed geroscience. He has published more than 100 papers and has twice received the Glenn Award for Research in Biological Mechanisms of Aging. He was the first faculty member at the Buck Institute to receive a senior scholarship from the Ellison Medical Foundation. He was one of the founding editors of the highly respected journal Aging Cell and served as the inaugural and founding chair of the Gordon Research Conference on Oxidative Stress and Disease.

Dr. Melov has extensive experience in working with biotech and pharma, having received numerous competitive awards from this sector and accumulated broad experience serving as a consultant. He has also served on more than 30 study sections for the National Institutes of Health.

  • Chandani Limbad, PhD  Research Scientist

    Chandani pursued an MS in Biomedical Engineering from NYU and a PhD in Comparative Biochemistry from UC Berkeley in conjunction with the Buck Institute. During her PhD she identified how senescence-driven damages in astrocytes lead to neuronal dysfunction. Her current research focus is to identify novel therapeutic targets for side effects of chemotherapy.

    Leyla Teos, PhD  Senior Staff Scientist

    Leyla Teos received her Ph.D. from Howard University in Washington D.C. in Physiology and Biophysics. Upon completion of her Ph.D., she joined the Molecular Cardiology lab of Dr. Jonathan Lederer at the University of Maryland in the Center for Biomedical Engineering & Technology; where she completed 3 years of postdoctoral training examining calcium signaling in compromised heart tissue. She was awarded a second postdoctoral fellowship and promoted to Molecular Biologist at the National Institute of Dental and Craniofacial Research (NIDCR) at the National Institute of Health. Her work at NIDCR led to the identification of the defect in calcium signaling at the IP3R3/E.R. calcium release level in patients with primary Sjogren’s Syndrome. She is currently working on the vulnerability of senescence on the cardiovascular system.
