Regulation of ovarian function by the TGF-beta superfamily and follistatin
Plain-language summary
Paraphrased from the published abstract below — not a verdict on whether anything works.
This review article summarizes research on follistatin and its interactions with members of the transforming growth factor beta (TGF-beta) superfamily, with emphasis on the ovary. The authors describe follistatin's long-studied role as an activin-binding protein and emerging evidence that it may modulate other superfamily members. They discuss follistatin biochemistry, the two isoforms follistatin-288 and follistatin-315, and the functions of growth differentiation factor 9 (GDF-9), bone morphogenetic protein 15 (BMP-15), BMP-6, BMP-4 and BMP-7 in ovarian regulation, along with potential interactions between follistatin and these growth factors. The article characterizes a complex regulatory network rather than reporting new experimental data.
Abstract
The role of follistatin as an activin-binding protein has dominated the study of this molecule for the last 10 years. However, there is emerging evidence that follistatin has a role in modulating the biology of other members of the transforming growth factor beta (TGF-beta) superfamily. This review summarizes the current concepts encompassing follistatin biochemistry as well as molecules with which it is functionally associated. Moreover, the importance of the two follistatin isoforms (follistatin-288 and follistatin-315) is discussed with particular emphasis on the regulation of the ovary. In addition to activin, this review discusses the functions of other members of the TGF-beta superfamily, for example growth differentiation factor 9 (GDF-9), bone morphogenetic protein 15 (BMP-15), BMP-6, BMP-4 and BMP-7, in the ovary, and the potential interactions between follistatin and these growth factors. The complex network of TGF-beta superfamily growth factor members involved in the modulation of ovarian function and the interactions of follistatin with these proteins is highlighted.
