PRKCA and hepatocellular carcinoma: ZEB1 and PRKCA mRNA expressions showed a significant (p = 2.2 × 10−16) and positive (r = 0.479) association, similar to that of ZEB1 and Vimentin (p = 3.04 × 10−8, r = 0.308, Supplementary Fig. S5), which confirms M-HCC specific expression of PKCα in human samples.
