Fig. 5From: Relationship between TRAF6 and deterioration of HCC: an immunohistochemical and in vitro studyEffect of TRAF6 siRNA on the cell apoptosis of HCC cells. HepG2 and Hep3B cells were transfected with TRAF6 siRNA and corresponding controls for 5 and 10 days. Cell caspase-3/7 activity was assessed by Hoechst/PI double staining (a HepG2,b Hep3B); Apoptosis was detected by Hoechst/PI double staining (c HepG2, d Hep3B). *P < 0.01, **P < 0.001Back to article page
