NMI and hepatocellular carcinoma: Knock-down of NMI by siRNA in HCC-LM3 cell induced a significant suppression of cell proliferation (*P < 0.05; Figure 2A), an increase in percentage of G0/G1 phase and a decreased the percentage of S phase compared with the control group (*P < 0.05; Figure 2B); but did not have significant effect on the apoptosis of HCC-LM3 cells (Supplementary Figure 2).
