Abstract:

Ovarian granulosa cells (GCs) are the basic guarantee of follicle development in female animals. In the past, it was widely believed that apoptosis of GCs could regulate follicle development. However, recent studies have found that GCs autophagy can also regulate follicle development. In the animal husbandry industry, the quality of follicle development is closely related to the reproductive rate of female animals, which directly affects the economic benefits of livestock farms. At present, more and more studies have shown that miRNAs are one of the factors regulating autophagy in GCs. Therefore, this article will review the research progress on the origin, structure and function of GCs, the importance of GCs autophagy on the ovary, the miRNAs associated with GCs autophagy of the ovary and their regulatory effects on follicle development, in order to provide references for future related studies.

Key words: ovarian granulosa cells, domestic animals, autophagy, miRNAs
