Abstract
- The regulation of spermatogonial stem cell (SSC) proliferation and self-renewal is a complex process. Several studies on the microRNA regulation of mammalian spermatogenesis have been reported. Here, we predicted miRNA targeting of Sirt1, and a dual luciferase experiment confirmed that miR-204 interacted with the Sirt1 3'-untranslated region (3'-UTR). The expression of miR-204 and Sirt1 in dairy goat testicles was investigated, and the results showed that the expression pattern of Sirt1 was similar to that of miR-204 in the temporal-spatial distribution. The over-expression of Sirt1 in goat SSCs can promote SSCs' self-renewal gene expression and cell proliferation. Furthermore, miRNA sequencing results showed that Sirt1 had a higher expression level in dairy goat CD49f(+) and CD90(+) SSCs, but the expression level of miR-204 was lower. In an in vitro assay, Sirt1 was significantly down-regulated in dairy goat SSCs when transfected with miR-204 mimics, indicating that Sirt1 was a target of miR-204 in the dairy goat. On the basis of the results of RT-qPCR, fluorescence-activated cell sorting (FACS), and western blotting, we found that the over-expression of Sirt1 in goat SSCs can promote cellular proliferation and change self-renewal and pluripotent gene expression. Thus, miR-204 was involved in the regulation of dairy goat SSCs proliferation via Sirt1. [ABSTRACT FROM AUTHOR]
