Garcinia mangostana and α-Mangostin Revive Ulcerative Colitis-Modified Hepatic Cytochrome P450 Profiles in Mice.
Pakistan journal of biological sciences : PJBS(2022)
摘要
<b>Background and Objective:</b> Ulcerative colitis (UC) is inflammation of the large intestine with ulceration but can also cause extraintestinal manifestations (EIM) by damaging surrounding organs such as the liver. <i>Garcinia mangostana</i> (GM) pericarp and α-mangostin (MGS) have been reported to have anti-inflammatory activity. This study evaluated the effects of GM pericarp extract and MGS on the expression of hepatic cytochrome P450 (CYP) enzymes as an EIM of UC. <b>Materials and Methods:</b> Male ICR mice were orally administered GM pericarp extract (40, 200 and 1000 mg/kg/day), MGS (30 mg/kg/day) or sulfasalazine (SUL) (100 mg/kg/day) daily for 7 days. On days 4-7, UC was induced by dextran sulfate sodium (DSS 40 kDa, 6 g/kg/day). Profiles of CYP mRNA expression were determined by RT/qPCR. Alkoxyresorufin <i>O</i>-dealkylation (including ethoxy-, methoxy-, pentoxy- and benzyloxy-resorufin), aniline hydroxylation and erythromycin <i>N</i>-demethylation CYP responsive activities were also examined. <b>Results:</b> The DSS-induced UC mice showed suppressed expression<i> </i>of <i>Cyp1a1</i>, <i>Cyp1a2</i>, <i>Cyp2b9/10</i>, <i>Cyp2e1</i>, <i>Cyp2c29</i>, <i>Cyp2d9</i>, <i>Cyp3a11</i> and <i>Cyp3a13</i> mRNAs. The GM pericarp extract and MGS restored expression of all investigated CYPs and their responsive enzyme activities in DSS-induced UC mice to levels comparable to the control and parallel to the effects of the anti-inflammatory control SUL. <b>Conclusion:</b> The GM is a promising therapy to restore UC-modified hepatic CYP profiles.
