The SIRT5-SUCLG2 desuccinylation axis delays ovarian aging via a mitochondrial-epigenetic regulatory mechanism.

Boosting a protein linked to ovarian aging delayed reproductive decline in mice, opening avenues for fertility preservation.

SIRT5-mediated SUCLG2 desuccinylation at K93/K101 links mitochondrial TCA cycle activity to histone acetylation in aging ovaries; a SUCLG2 desuccinylation mutant gene therapy ameliorated ovarian aging in vivo. This record was retained from the prior triage attempt for PubMed pipeline handoff.
