Figure 5From: MicroRNA-21 promotes hepatocellular carcinoma HepG2 cell proliferation through repression of mitogen-activated protein kinase-kinase 3 Impact of miR-21 on HepG2 cell proliferation. HCC HepG2 cells were infected with Ad/miR-21/inhibitor (miR-21 sponges) or pAd/con virus at MOI 0f 10, the index of cell proliferation was assessed by an MTT assay from 24 to 72 hours. Compared with Ad/con group, *: p<0.05. Data in A represented the mean ± SD from three independent triplicated experiments (N=9).Back to article page
