Abstract

Induction of xenobiotics metabolizing enzymes is related to the formation and chemoprevention of cancer. Since cytochrome P450s (CYPs) including CYP1A subfamily metabolize certain pro-carcinogens to their ultimate forms, down-regulation of CYP1As by food factors leads to the prevention of cancer. Mushroom polysaccharides, especially β-glucans such as lentinan from Lentinus edodes, possess the anti-tumor and immunomodulating activities through the cytokine production from immunocytes. Recent our studies have demonstrated that lentinan suppresses hepatic CYP1As expression in the both constitutive and inducible levels through the production of tumor necrosis factor-α and an increase in the DNA-binding activity of nuclear factor-κB. This paper discusses on the effective lentinan dosage and route of administration for suppression of CYP1As.
