ABSTRACT
Bone morphogenetic protein 15 (BMP15) regulates the growth and development of follicles. In particular, the long non-coding RNA H19 plays an important role in mammalian reproduction. However, the function and regulatory mechanism of the interaction of BMP15 with H19 in yak granulosa cell (GC) proliferation, autophagy, and apoptosis are poorly understood. In our study, quantitative reverse-transcription-polymerase chain reaction analysis showed that H19 were highly expressed in yak healthy follicles. H19 was induced by BMP15 protein in yak GCs. In addition, we confirmed that overexpression of H19 promoted yak GC proliferation and autophagy and inhibited apoptosis. Bioinformatic analysis and luciferase reporter assays demonstrated that H19 directly binds to miR-26b, and SMAD1 was identified as a target of miR-26b. miR-26b overexpression inhibited GC proliferation and autophagy and promoted apoptosis through decreased SMAD1 expression, which was attenuated by H19 overexpression. RNA immunoprecipitation-quantitative polymerase chain reaction and dual-luciferase assays showed that miR-26b was sponged by H19 to preserve SMAD1 expression. Furthermore, SMAD1 mRNA expression was induced and miR-26b expression was reduced after yak GCs were treated with BMP15 protein. In conclusion, our results demonstrated that the H19/miR-26b/SMAD1 axis responds to BMP15 to regulate yack GC proliferation, autophagy, and apoptosis.
