miR-10b promotes porcine immature Sertoli cell proliferation by targeting the DAZAP1 gene

Abstract

MicroRNAs (miRNAs) have been widely identified in porcine testicular tissues and implicated as crucial regulators of proliferation, apoptosis, and differentiation in porcine spermatogenesis related cells. However, the function roles of most of the miRNAs that have been identified in Sertoli cells are poorly understood. In the present study, six experiments were conducted to study the regulatory role of miR-10b in porcine immature Sertoli cells. In experiment 1, the results showed that the relative mRNA expression level of miR-10b in porcine testicular tissues decreased quadratically (P0.05) on porcine immature Sertoli cell apoptosis. In experiment 6, the co-transfection treatment results showed that miR-10b promoted (P<0.05) porcine immature Sertoli cell proliferation by targeting DAZAP1 gene. Overall, these experiments demonstrated that miR-10b promotes porcine immature Sertoli cell proliferation by targeting the DAZAP1 gene.
