CALB1 and RPL23 Are Essential for Maintaining Oocyte Quality and Function During Aging
Aging Cell, EarlyView.This study investigates the mechanisms of oocyte aging in mice, identifying Calb1 and Rpl23 as key genes involved in calcium ion homeostasis and mitochondrial function. Knockdown of these genes led to mitochondrial dysfunction, meiotic defects, and spindle assembly abnormalities, while their overexpression partially rescued age‐related oocyte defects ...
