In a study by Tsunedomi et al. including tumor samples from 81 hepatocellular carcinoma patients, higher ABCB6 mRNA levels have been found in hepatitis C virus (HCV)-related hepatic cancers with early intrahepatic recurrence compared to HCV-related cancers without early recurrence and the corresponding non-cancerous livers [156]. Here, ABCB6 is linked to hepatocellular carcinoma.
