GSTO1 and hepatocellular carcinoma: The authors focused on hepatitis B virus (HBV) infection-associated liver diseases and found that both homozygous and heterozygous wild-type GSTO1*A140 (i.e., A/C and C/C genotypes) were more prevalent in all the patient groups analyzed, including normal HBV carriers (N) and acute (A), chronic (CH), cirrhosis (CI), and hepatocellular carcinoma (HCC) patients, compared to healthy controls.
