摘要： Our previous study showed that the expression of miR-196a was significantly higher in immature porcine testes than in mature porcine testes. However, the role of miR-196a in immature Sertoli cells remains unclear. In this study, miR-196a mimics, miR-196a inhibitor, and microRNA-small hairpin negative control (miRNA-ShNC) were transfected into immature Sertoli cells, respectively. Subsequently, the cell cycle and apoptosis rate of the immature Sertoli cells were measured by flow cytometry, and the viability of the Sertoli cells was measured by the MTS assay. Furthermore, the candidate target genes of miR-196a were analyzed by bioinformatics, and the target genes were validated by dual luciferase reporter assays, then the expression of target genes was detected by real-time quantitative polymerase chain reaction (RT-qPCR) and Western blot assays. The results showed that miR-196a promotes the proliferation and inhibits the apoptosis of immature Sertoli cells. miR-196a directly binds the 3 untranslated region (3 UTR) of RCC2 and ABCB9. The expression of miR-196a was shown to be negatively correlated with the messenger RNA and protein levels of the RCC2 and ABCB9 genes. The study demonstrates that miR-196a regulates immature Sertoli cell proliferation and apoptosis and inhibits the expression of RCC2 and ABCB9.
