The levels of lipid peroxidation and marker enzymes [aryl hydrocarbon hydroxylase (AHH), adenosine deaminase (ADA), gamma-glutamyltranspeptidase (GGT), and LDH] were significantly increased in benzo (a) pyrene-induced lung cancer animal models, which returned to near-normal levels following crocetin treatment. Here, ADA is linked to lung cancer.
