Expression of Protein Kinase C Family in Human Hepatocellular Carcinoma
2010
Protein kinase Cs (PKCs) play important roles in signal transduction, cell regulation, and tumor formation. In the present study, we analyzed the expression of PKCs in human hepatocellular carcinoma (HCC) tissues and explored their roles in the development of HCC. Real-time quantitative PCR and immunohistochemistry showed that PKCβ and PKCθ were down-regulated in HCC tissues. Reduced expression of PKCθ is well correlated with the grade of cancer cells (p = 0.009), and the down-regulated expression of PKCβII is associated with HBV infection (p = 0.035). Our findings suggest particular roles of the two PKC isoenzymes in the hepatocarcinogenesis of human HCC.
