$2.375 million federal award to study epigenetic control systems, inform drug discovery
September 20, 2017 (Grand Rapids, Michigan)–Van Andel Research Institute scientist Scott Rothbart, Ph.D., has been awarded a five-year, $2.375 million Maximizing Investigators' Research Award (MIRA/R35) from the National Institute of General Medical Sciences (NIGMS) of the National Institutes of Health that will fuel in-depth, multidisciplinary studies into the epigenetic control mechanisms that regulate the genetic code.
"Epigenetic mechanisms are at the root of biology and are implicated in all aspects of health and disease throughout a person's life," Rothbart said. "Thanks to this award, we can focus on the big picture–how are these incredibly complex and nuanced controls orchestrated and how can we leverage this knowledge to rationally design more effective medications that ultimately improve human health?"
The grant provides "the nation's highly talented and promising investigators" with "greater stability and flexibility, thereby enhancing the scientific productivity and the chances for important breakthroughs," according to NIGMS.
A molecule of particular interest to the lab is the protein UHRF1, which serves as a central hub for epigenetic regulation. Although previous work by Rothbart and others in the field has started defining its function, little is known about how UHRF1 does its job. Rothbart aims to change that, and to translate the results into tangible improvements in patient care.
"Understanding what goes on behind the scenes through basic scientific discovery is the starting point for a potential wave of new epigenetic therapies," he said. "The more information we have, the more opportunities exist to harness this knowledge in a real, impactful way."
The implications go far beyond understanding UHRF1 itself, and may serve as a paradigm for studying other crucial regulatory and molecular communication systems. His efforts will be bolstered by VARI's recently installed suite of cryo-electron microscopes, which can visualize molecules such as proteins down to the atomic level.
Rothbart joined VARI in 2015 as assistant professor in its Center for Epigenetics following a postdoctoral fellowship at University of North Carolina, Chapel Hill. While there, he was awarded a Pathway to Independence (K99/R00) grant from the National Institutes of Health, a competitive program designed to support promising early career scientists as they launch their own independent research programs.
