Effect of miR-20b on the invasion and proliferation of MG63 and U2OS cells. MG63 and U2OS cells were transfected with miR-20b mimic, mimic control, miR-20b inhibitor, or inhibitor control, respectively. (A) The relative miR-20b levels in MG63 and U2OS cells were measured by qRT-PCR. (B) The number of invading MG63 and U2OS cells. The proliferation of MG63 (C) and U2OS (D) cells was determined at the indicated time points by MTT assays. All experiments were repeated three times with three replicates. *p < 0.05 compared to mimic control group; #p < 0.05 compared to inhibitor control group.
