Chinese researchers identified histone demethylase LSD1 as a critical guardian of ovarian reserve. When deleted in mouse oocytes, LSD1 deficiency disrupted mitochondrial homeostasis and triggered ferroptosis, causing massive loss of dormant primordial follicles. This discovery explains how dormant follicles ("second wave") are maintained differently from active follicles ("first wave") and provides a foundation for treating premature ovarian insufficiency.
In order to elucidate the mechanisms underlying NET activation and its impact on MIRI, Hongru Zhang/Senlei Xu of Nanjing University of Chinese Medicine (NJUCM), along with Yanfei Mo of Pukou Hospital of Chinese Medicine, confirm that the generation of NETs by neutrophils exacerbates microvascular endothelial cell injury, thereby worsening MIRI.
The cold winter snaps might make it hard to get out and about, but new research led by the University of South Australia has found that frequently attending in-person events can significantly boost wellbeing.
