HCC development was confirmed by histopathology analysis that showed atypical lesions of HCC; this may be due to the catabolism of DAB by cytochrome P-450 enzymes, which results in the creation of reactive oxygen species (ROS), toxic electrophiles, and DNA adducts that produce liver tumors (Thomas et al. 2016). Here, CYP4F3 is linked to hepatocellular carcinoma.
