Figure 8From: Increased MiR-221 expression in hepatocellular carcinoma tissues and its role in enhancing cell growth and inhibiting apoptosis in vitro Effect of miR-221 on cell growth of HCC cells by Hoechst 33342/propidium iodide (PI) double fluorescent chromatin staining. HCC cells were treated the same as in Figure 5 and the cell growth was monitored with Hoechst 33342/PI double fluorescent chromatin staining. * P<0.05, ** P<0.01, compared to blank control at the same time point.Back to article page
