Abstrakt: Objective: To investigate the effect of microRNA-20a(MiR-20a) on osteogenic differentiation of mouse C3H/10T1/2 cells and its regulatory mechanism.
Methods: Osteogenic differentiation of C3H/10T1/2 cells were identified by ALP staining and qRT-PCR. MiR-20a mimics and CKIP-1 siRNA were transfected into C3H/10T1/2 cells respectively with lipo3000. The expression of osteoblast marker genes, miR-20a and CKIP-1 were quantitatively assessed by qRT-PCR.
Results: miR-20a expression was up-regulated during osteoblast differentiation of C3H/10T1/2 cells. Overexpression of miR-20a promoted osteogenic differentiation. Furthermore, miR-20a inhibited the expression of bone formation negative regulator CKIP-1. Additionally, CKIP-1 knockdown promoted osteogenic differentiation.
Conclusion: MiR-20a promotes osteogenic differentiation of C3H/10T1/2 cells possibly through inhibiting the expression of CKIP-1.
