FAK silencing influences EZH2 expression and activity in HCC cells. (a) Relative mRNA expression of EZH2 gene as measured by quantitative Real-Time PCR (qRT-PCR) in Control and shFAK HepG2 and Huh6 cells. Values are expressed as fold mean±SD (*P<0.05; ***P<0.001; n=3). (b) Representative WB and densitometric quantification for EZH2 protein in Control and shFAK HepG2 and Huh6 cells. GAPDH is reported as a loading control (***P<0.001; n=3). (c) Representative WB of H3K27me3 in Control and shFAK HepG2 and Huh6 cells. GAPDH is reported as a loading control (n=2). (d) Representative WB of cytosolic and nuclear EZH2 protein in Control and shFAK HepG2 and Huh6 cells. GAPDH and C23 are reported as loading controls (n=2). (e) Average fluorescence intensity calculated for FAK, EZH2 and H3K27me3 in liver tumor (HCC) and non-tumor (Normal) samples from the same patients (n=16). Values are plotted as mean±SD (***P<0.001). (f) Average fluorescence intensity calculated for FAK, EZH2 and H3K27me3 in HCC samples according to tumor staging. Values are plotted as mean±SD (*P<0.05; **P<0.01). (g) Heatmap representation of the expression of FAK, EZH2 and H3K27me3 in Normal tissues and HCC according to grade of disease (I, II, II).
