Wistar Institute team finds key target of aging regulator
Date:6/10/2009

erger says. "Characteristic epigenetic features have been discovered for various developmental processes in recent years. Understanding epigenetic changes associated with aging is a hugely exciting direction in aging research. It will provide insights and ideas not only for new therapies to regulate cells that have lost control of proliferation, such as 'immortal' cells found in cancers, but also for new strategies to maintain health and fitness."

"We plan to continue to search for new targets of Sir2 and other aging regulators," says lead author Weiwei Dang, Ph.D., a postdoctoral scientist working with Berger. "We are designing unbiased screens for other aging targets and mechanisms in chromatin. Using yeast as our aging model enables us to do many discovery screens that are impossible with other, more complex organisms. Yet it is remarkable that many of these chromatin mechanisms associated with yeast could turn out to be relevant even for aging human cells."
