Serum manganese superoxide dismutase and thioredoxin are potential prognostic markers for hepatitis C virus-related hepatocellular carcinoma

Figure 1 Serum levels of manganese superoxide dismutase and thioredoxin in the hepatocellular carcinoma, non-hepatocellular carcinoma and healthy volunteer groups. A: Serum manganese superoxide dismutase (MnSOD) levels were significantly higher in the hepatocellular carcinoma (HCC) group than in either the non-HCC group (P = 0.03) or the healthy volunteers (HV) group (P < 0.001); B: Serum thioredoxin (TRX) levels were also significantly higher in the HCC group than in either the non-HCC group (P = 0.04) or the HV group (P < 0.01); C: No significant correlation was detected between serum MnSOD and TRX levels in the HCC group.
