Expression of selected miRNAs is evaluated in HCC cell lines.

<p>The miRNAs (miR-16, miR-26b, miR-101, miR-199a, miR-122 and miR-21) were selected by using miRWalk computational analysis as described in Methods. The expression profile was analyzed in HCC cell lines using real-time PCR, normalized against U6 RNA levels and refers to human hepatocytes (HH) as 1. COX-2 protein/mRNA ratio was compared to miRNAs expression in HCC cells and the coefficient of determination (R²) was calculated.
