When we determined GPR119 mRNA expression in HepG2, SNU-449 and SK-Hep1 hepatocellular carcinoma cell lines, GPR119 mRNA was similarly detected in HepG2 and SNU-449 cells, but its expression level was relatively low in SK-Hep1 cells (Fig. 4e). This evidence concerns the gene GPR119 and hepatocellular carcinoma.
