Effect of PP7 on the NF-κB/MMP-9/VEGF pathway in HepG2 cells. a Western blot analysis for NF-κB p65 in the nuclear and cytoplasmic extracts of HepG2 cells. (B) MMP-9 and VEGF protein levels were determined via Western blotting. c, d were densitometric analysis of a. e, f were densitometric analysis of b. Values are expressed as means ± SD of triplicate experiments. *P < 0.05, **P < 0.01, versus control groups
