Abstract

Conflicting data on the anticancer properties of the polyphenolic natural product resveratrol (RSV) have been reported. Since the inhibition of "bioactivating" Phase-I xenobiotic metabolizing enzymes (XMEs) and/or induction of "detoxifying" Phase-II XMEs have long been considered important cancer chemopreventive strategies, in the current study we investigated the effect of RSV treatment on several Cytochrome P450 (CYP)-dependent oxidations and Phase-II markers in liver and lung subcellular preparations from CD1 male mice. These mice were i.p treated with RSV (25 or 50 mg/Kg b.w.) daily for one or for seven consecutive days. Using either specific probes for different CYPs, or the regio- and stereo-selective metabolism of testosterone, we found that most of the Phase-I XMEs were significantly suppressed (up to ∼61% loss for the CYP3A1/2-linked 6 β-hydroxylation of testosterone in liver and up to ∼97% loss for 2 α-hydroxylase in lung) following RSV treatment for 7 days at 50 mg/kg b.w. Glutathione S-transferase was significantly inhibited, particularly in lung (∼76% loss of activity) after single administration of 25 mg/kg b.w. A different response for the UDP-glucuronosyl transferase was observed, where a significant induction was seen (∼83%) in the liver and a significant reduction was observed in the lung (up to ∼83% loss) following treatment with 25 mg/kg b.w. for seven days. These data indicate that murine XMEs are altered by RSV, and that this alteration is dependent on the RSV dose, duration and way of administration. These results could provide mechanistic explanations for the conflicting chemopreventive results reported for RSV.
