An overlooked protein may decide how fast male fertility starts to unravel with age

A study led by researchers at the Universitat Autònoma de Barcelona (UAB) and the Josep Carreras Leukemia Research Institute (IJC) along with researchers from Rutgers University (U.S.) has identified the Sirtuin 7 (SIRT7) protein as a new essential factor in maintaining the genome stability of male germ cells over time. The study, conducted with mice, is published in the journal Nature Communications.
