Cover Story: Enhancer of zeste homolog 2 (EZH2) is an epigenetic modulator that catalyzes trimethylation on lysine 27 of histone 3 (H3K27) in the chromatin, condensing its structure and inhibiting gene expression. Dysregulation of EZH2 in the uterus and other organs has been linked with pathologies that often involve aberrant cell proliferation. To understand the uterine role of EZH2, a conditional knockout mouse model lacking Ezh2 in progesterone receptor-positive cells has been developed, and these mice show uterine hypertrophy, cystic endometrial hyperplasia, aberrant epithelial proliferation, and altered estrogen responsiveness. This review discusses the roles of EZH2 in the uterus and placenta in health and disease. View this paper
