“…Specific expression of miRNAs is found in different periods of mouse testes through gene chip and miRscan, and it has been confirmed that follicle stimulating hormone and androgen can regulate male reproductive activity through the expression of miRNAs in SCs (Mishima et al, ; Nicholls et al, ; Wu, Bao, Wang, Hu, & Xu, ; Yan et al, ). Recent studies have demonstrated that miRNAs repress the expression of SC target genes, thereby regulating SC proliferation, maturation, apoptosis, blood‐testis barrier, and stages of the seminiferous epithelium cycle (Jiao et al, ; Ma et al, ; Yao et al, ). Specific knockdown of Dicer, a central component of RNA interference machinery, downregulates the expression of several key genes in SCs and results in male infertility because of spermatozoa absence and progressive testicular degeneration (Papaioannou et al, ; Papaioannou et al, ).…”
