Unlocking Another Key to Aging

Unlocking Another Key to Aging

Transposons, also known as “jumping genes,” are DNA sequences that move from one location in the genome to another. Transposons are thought to contribute to aging, but their actual role remains to be clarified. The National Institute on Aging has awarded Julie Secombe, Ph.D., a five-year, $1.69 million grant to study whether transposons influence aging. So far, research on transposons and aging has been limited by available techniques. Dr. Secombe and her team will use novel methods to analyze the genomes of single cells. They will also focus on the role of Myc, a transcription factor (i.e., a protein regulating gene expression) known to affect aging in model organisms. By determining interconnections among Myc transposons that contribute to aging, the team may develop strategies for suppressing this activity and, ultimately, improve human longevity. Dr. Secombe is associate professor of genetics and is associate professor in the Dominick P. Purpura Department of Neuroscience. (1R01AG053269-01A1)
