In addition, genes mRNA and protein levels were detected after bull testicular Sertoli cells were transfected with miR-122 and miR-449a. Meanwhile, DUSP4, PDK4 and FKBP1B overexpression experiments were conducted. Eventually, MTT assay was performed to observe the cells proliferation. The results showed that miR-122 and miR-449a were highly-expressed in testi...
