result sql = Piceatannol is an anti-inflammatory and anti-proliferative plant-derived stilbene. Heme oxygenase-1 (HO-1) is a cytoprotective enzyme to activate by various phytochemicals. In this study, we examined the ability of piceatannol to upregulate HO-1 expression in endothelial cells. We found piceatannol at micromolar (10-50 microM) concentrations dramatically increased HO-1 protein levels in a time-dependent manner. Piceatannol was similarly potent in the induction of HO-1 as hemin, arsenate, and 15d-PGJ2, and was more potent than some other phytochemicals including curcumin, EGCG, baicalein, and quercetin. In contrast, the similar chemical structure compounds, trans-stilbene, stilbene oxide, and resveratrol had no HO-1-inducing effects, suggesting a critical role for the hydroxyl groups in HO-1 induction. No cytotoxicity and superoxide production was observed after 10-50 microM piceatannol treatments. Piceatannol-mediated HO-1 induction was abrogated in the presence of N-acetylcysteine and glutathione, but not by other antioxidants. Induction of HO-1 by piceatannol was further enhanced by using buthionine sulfoximine. In addition, we determined that tyrosine kinase was involved in the induction of HO-1 by using tyrosine kinase inhibitors, herbimycin A, erbstatin, and genistein; in contrast, no significant changes in the pretreatment of PI3 kinase or MAP kinase inhibitors was determined. HO-1 induction was blocked by the protein kinase C inhibitors calphostin C, rottlerin, and long PMA pretreatment, whereas conventional PKC inhibitors, Go6976, and Ca2+ chelator BAPTA/AM, had no effect. Elevated HO-1 protein levels were associated with the inhibition of tumor necrosis factor-alpha (TNFalpha)-induced intercellular adhesion molecule-1 (ICAM-1) expression. Treating ECs with zinc protoporphyrin, an HO-1 inhibito blocked the anti-inflammatory effect of piceatannol. In summary, this study identified piceatannol as a novel phytochemical inducer of HO-1 expression and identified the mechanisms involved in this process.
