Focal Adhesion Kinase (FAK) Over-Expression and Prognostic Implication in Pediatric Hepatocellular Carcinoma.

ABSTRACT: Focal adhesion kinase (FAK) is over-expressed and is correlated with aggressiveness in adult hepatocellular carcinoma (HCC). Inhibition of FAK decreases HCC invasiveness by down-regulating Enhancer of Zeste homolog 2 (EZH2), an epigenetic controller, that acts in transcriptional repression of a large number of genes via histone 3 methylation of lysine 27 (H3K27me3). Here, we investigated the hepatic expression of total FAK, EZH2, H3K27me3, and proliferating cell nuclear antigen (PCNA) in 17 pediatric HCCs and 8 healthy livers (CTRL). Quantitative imaging analysis showed that FAK gene/protein expression is up-regulated in HCCs compared to CTRL and, among tumor samples the levels of this gene/protein are significantly higher in cirrhotic HCCs than in a healthy milieu. Accordingly, the protei
