Single gene rejuvenates aged cells and extends mouse lifespan
Harvard researchers identified SRSF1, an RNA splicing factor, as a geroprotective target that reverses multiple hallmarks of aging in human cells and extends median lifespan by 14% in mice. The study demonstrates a safer alternative to Yamanaka factor reprogramming by rejuvenating cells without erasing their identity.
