Abstract: Microribonucleic acid (microRNA, miRNA) is a type of endogenous non-coding RNA, which have a wide range of gene expression regulation.They can regulate the expression of corresponding proteins by affecting target genes at the post-transcriptional level, and then regulate cell life activities.miRNA is expressed in mammalian follicular granulosa cells and regulate the apoptosis of granulosa cells.Granulosa cells, as the most numerous cell group in ovarian follicles, play a vital role in the process of follicular development.They not only provide nutrients for oocytes, but also regulate their development and maturity.Granulosa cell apoptosis is an important cause of follicle atresia, which affects the number and quality of follicles and thus affecting the reproductive performance of female animals.The apoptosis of granulosa cells is regulated by a variety of factors.This paper briefly describes the regulatory effect and mechanism of miRNA on ovarian granulosa cell apoptosis, including miRNA regulating granulosa cell apoptosis by regulating hormone secretion and the expression of apoptosis-related factors, the effect of miRNA on granular cell apoptosis related signal pathway, miRNA regulating ovarian-derived diseases caused by granular cell apoptosis, and summarizes the miRNA that regulate granular cell apoptosis and the potential role of miRNA in disease diagnosis and treatment, in order to provide guidance and reference for the pathogenesis and treatment of subsequent related ovarian diseases and improve the reproductive performance of female mammals.

Key words: granulosa cells; apoptosis; ovarian-derived diseases; miRNA
