What accounts for longer lifespan? According to new research from biologists at the University of Rochester, a key piece of the puzzle lies in the mechanisms that regulate gene expression.
In a paper published in Cell Metabolism, the researchers, including Vera Gorbunova, the Doris Johns Cherry professor of biology and medicine; Andrei Seluanov, professor of biology and medicine; and Jinlong Lu, a postdoctoral research associate in Gorbunova's lab and the first author of the paper, investigated genes connected to lifespan. Their research uncovered specific characteristics of these genes and revealed that two regulatory systems controlling gene expression—circadian and pluripotency networks—are critical to longevity. The findings have implications both in understanding how longevity evolves and in providing new targets to combat aging and age-related diseases.
