The HCC-induced rats displayed a significant increase in the serum levels of liver enzymes—aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP), total proteins (TP) and conjugated bilirubin (direct bilirubin)—versus the control group (p < 0.05) (Figure 3). This evidence concerns the gene GPT and hepatocellular carcinoma.
