SIRT7 links H3K36ac epigenetic regulation with genome maintenance in the mouse testis
A mouse study reveals how a protein maintains sperm health during aging, opening research avenues for male reproductive health.
This mouse study demonstrates that SIRT7 maintains genome stability in male germ cells by regulating H3K36 acetylation, and its loss phenocopies epigenetic aging changes in spermatogonia. Findings have implications for understanding male reproductive aging mechanisms but are at early preclinical stage.
