TH and hepatocellular carcinoma: RMT induced a significant increase in the expression of tyrosine hydroxylase (Th, p = 0.036 for Bl6 and p = 0.0009 for 129Sv), Comt (for both p ≤ 0.0001), Maoa (for both p ≤ 0.0001) and Maob (for both p ≤ 0.0001) in both strains compared to the HCC group (Figure 8C–F).
