• MiRNAs play an important role in cell proliferation, apoptosis, and differentiation. MiR-18a is increasingly being recognized as a regulator of cancer pathogenesis. Here, we discovered that miR-18a participates in myoblasts proliferation. Expression of miR-18a was downregulated with the differentiation of C2C12 myoblasts. Overexpression of miR-18a affected the proliferation of C2C12 cells, primary myoblasts and RD cells. MiR-18a influenced the expression of cell cycle-related genes. Using TargetScan 6.2, we found that the 3' untranslated region (UTR) of the mouse Fgf1 gene contains complementary sequences to miR-18a. Using a siRNA, we confirmed that the reduction in the Fgf1 levels inhibited proliferation of C2C12 cells. Therefore, our results show that miR-18a participates in the regulation of proliferation by partly decreasing the expression of Fgf1.
