Research progress in biological activities and oocyte aging-regulating effect of EGCG

Abstract:

Epigallocatechin gallate (EGCG), the predominant polyphenol in green tea, exerts a spectrum of physiological activities, including antioxidant, anticancer, and anti-inflammatory effects. Emerging research underscores the significance of EGCG in modulating oocyte aging. EGCG can enhance antioxidant defenses, improve mitochondrial functions, and inhibit apoptotic pathways, thereby retarding the aging of oocytes. This review delineates the main molecular features of EGCG and expounds its regulatory mechanisms concerning oocyte aging, enriching the knowledge on the role of EGCG in the amelioration of oocyte aging.
