Effects of testosterone on the expression levels of AMH, VEGF and HIF-1α in mouse granulosa cells

The present study aimed to investigate the effects of testosterone on mouse granulosa cell morphology, and the expression levels of anti-Mullerian hormone (AMH), vascular endothelial growth factor (VEGF) and hypoxia-inducible factor-1α (HIF-1α). Mouse granulosa cells were isolated and identified, and their morphology was examined using hematoxylin and eosin, F-actin, and follicle-stimulating hormone receptor staining. The mRNA expression levels of AMH, VEGF and HIF-1α were examined using reverse transcription-quantitative polymerase chain reaction, and their protein secretion levels were investigated using enzyme-linked immunosorbent assays. Testosterone treatment did not affect granulosa cell morphology; however, it significantly increased the mRNA expression levels of AMH and VEGF, and the protein secretion levels of AMH, VEGF and HIF-1α. These results suggested that testosterone was able to regulate the functions of granulosa cells by upregulating the expression levels of AMH, VEGF and HIF-1α.
