Two scientists receive prestigious awards to pursue high-risk, high-reward research
Sanford Burnham Prebys Medical Discovery Institute today announced that two faculty members, Peter Adams, PhD, and Jerold Chun, MD, PhD, have received National Institutes of Health (NIH) Director’s Transformative Research Awards. The awards, which total $8.5 million and are two of only nine granted in 2020, come from the NIH Common Fund’s High-Risk, High-Reward Program. The program supports researchers who propose groundbreaking, exceptionally innovative research with the potential to create new scientific paradigms, establish entirely new and improved clinical approaches or develop transformative technologies.
Adams, a professor in the Tumor Initiation and Maintenance and Development, Aging and Regeneration Programs, was awarded a five-year, $3.9 million grant to study how chromatin—the mix of DNA and proteins that make up human chromosomes—is stabilized in long-lived cells. Increasingly, scientists are learning that modifications in chromatin structure correlate with age, and view its stability as a potential target to counter human aging and age-related diseases. Conversely, chromatin instability is thought to promote aging and disease.
“Chromatin is not a static fixed structure,” says Adams. “It’s a dynamic and plastic ‘breathing’ complex, but it needs a level of stability, especially for cells that need to survive and maintain their function for decades, such as neurons in our brain and cardiomyocytes in our heart. Our research will expand our understanding of how long-lived cells preserve chromatin integrity through a process we have called “chromostasis.”
“Aging is the single most important risk factor for many chronic, debilitating diseases,” adds Adams. “We hope our research leads to innovative approaches to support healthy aging, prevent degenerative disease and cancer, and facilitate therapeutic cell reprogramming.”
Chun, a professor in the Degenerative Diseases Program and senior vice president of Neuroscience Drug Discovery, was awarded a five-year, $4.6 million grant to advance a new line of research for Alzheimer’s disease and related dementias.
Chun’s team recently discovered that a process called “somatic gene recombination” occurs in neurons of the brain, creating new gene variants that are worsened in Alzheimer’s disease. The team will now look at related neurodegenerative diseases beyond Alzheimer’s disease and delve deeper into the processes that could produce disease-linked variants to provide new understanding and therapeutics.
“Alzheimer’s disease and related dementias like Parkinson’s disease affect millions of people in the U.S. alone, yet lack meaningful therapies” says Chun. “We are grateful to the NIH Common Fund and the National Institute on Aging for this support to explore a new facet of brain science that could help individuals and families impacted by these devastating diseases.”
“The breadth of innovative science put forth by the 2020 cohort of early career and seasoned investigators is impressive and inspiring," adds NIH Director Francis S. Collins, MD, PhD “I am confident that their work will propel biomedical and behavioral research and lead to improvements in human health.”
Adams’ grant is titled: Defining chromostasis—a candidate regulator of healthy aging and longevity (R01 AG071464-01).
Chun’s grant is titled: Transformative research on somatic gene recombination in the normal and Alzheimer's disease-related dementia brain (R01 AG071465-01).
