ASB1 engages with ELOB to facilitate SQOR ubiquitination and H2S homeostasis during spermiogenesis
Published 2025-02-01“…Subsequent investigations unveiled that Asb1 knockout (Asb1-KO) mice encountered excessive oxidative stress and decreased hydrogen sulfide (H2S) levels in their testes, and severe sperm DNA damage. Notably, the compromised fertility and sperm quality in Asb1-KO mice was significantly ameliorated by administering NaHS, a H2S donor. …”
