Abstract:

Bone morphogenetic protein 15 (BMP15) as an oocyte-secreted factor is vital to the regulation of follicle development. BMP15 promotes the development and maturation of oocytes by cooperating with amphiregulin and up-regulating the expression of cumulus expansion genes. BMP15 also promotes the proliferation and differentiation of granulosa cells by increasing the sensitivity of granulosa cells to FSH and stimulating the expression of Kit ligands in granulosa cells. BMP15 inhibits follicular atresia by regulating the expression of follicle apoptosis-related factors; and BMP15 can also mediate the regulation of steroid hormones by regulating the FSH receptor and the downstream Smad signaling pathways. The decreased expression or gene mutation of BMP15 may induce the apoptosis of granulosa cells, hinder the process of early follicle development and oogenesis, and mediate the pathogenesis of various diseases such as polycystic ovary syndrome and premature ovarian insufficiency. In this article, we review the roles of BMP15 in folliculogenesis and the research progress of BMP15-related reproductive endocrine diseases.
