Figure 5: The effects of NK-lysin on relative mRNA expression levels in SMMC-7721 cells. Cells of different groups were incubated for 72 hrs, and qRT-PCR was used to evaluate mRNA expression levels. Relative mRNA expression of β-catenin (a) and MMP-2 (b). The values are presented as the mean ± SEM (n=3), P<0.05, P<0.01, and P<0.001 vs. the NT Ctrl group.
