Sulfation of hesperetin, naringenin and apigenin by the human cytosolic sulfotransferases: a comprehensive analysis.

ABSTRACT: Previous studies have revealed sulfation as a major pathway for the metabolism of hesperetin, naringenin and apigenin. The current study was designed to identify the human cytosolic sulfotransferase (SULT) enzyme(s) capable of sulfating these flavonoid compounds. Of the thirteen human SULTs, six (1A1, 1A2, 1A3, 1B2, 1C4, 1E1) displayed significant sulfating activity toward hesperetin, five (1A1, 1A2, 1A3, 1B2, 1C4) displayed sulfating activity towards naringenin, and four (1A1, 1A2, 1A3, 1C4) showed sulfating activity towards apigenin. Of the four human organ specimens tested, liver and intestine cytosols displayed much higher hesperetin-, naringenin- and apigenin-sulfating activity than lung and kidney cytosols. Moreover, sulfation of hesperetin, naringenin and apigenin was shown to take place in HepG2 human hepatoma cells and Caco-2 human colon adenocarcinoma cells under cultured conditions. Taken together, these results provided a biochemical basis underlying the metabolism of hesperetin, naringenin and apigenin through sulfation in humans.[Formula: see text].

Project description:Cytosolic sulfotransferases (SULTs) catalyze the sulfate conjugation of a myriad of endogenous and xenobiotic substrates. Among the 13 human SULTs, little is known regarding regulation of the SULT1C subfamily. We evaluated the effects of a panel of transcription factor activators on levels of SULT1C mRNA (1C2 and 1C3) and protein (1C2) in LS180 colorectal adenocarcinoma cells. Treatment with 3-[3-[N-(2-chloro-3-trifluoromethylbenzyl)-(2,2-diphenylethyl)amino]propyloxy]phenylacetic acid hydrochloride [GW3965, liver X receptor (LXR) activator], 3-(2,6-dichlorophenyl)-4-(3'-carboxy-2-chlorostilben-4-yl)oxymethyl-5-isopropylisoxazole [GW4064, farnesoid X receptor (FXR)], or rifampicin [pregnane X receptor (PXR)] moderately (?2-fold) increased both SULT1C2 and SULT1C3 mRNA levels. 1?,25-Dihydroxyvitamin D3 [1,25(OH)2D3, vitamin D receptor (VDR)] selectively upregulated SULT1C2, whereas ciprofibrate [peroxisome proliferator-activated receptor ? (PPAR?)], rosiglitazone (PPAR?), and 2,3,7,8-tetrachlorodibenzo-p-dioxin [aryl hydrocarbon receptor (AhR)] selectively increased SULT1C3 mRNA levels. SULT1C2 protein content was strongly increased by 1,25(OH)2D3 treatment and moderately increased by GW3965, GW4064, and rifampicin. To evaluate SULT1C2 transcriptional regulation, treatment effects were determined on reporter activity from transfected constructs containing ?10 kb of the SULT1C2 gene. Treatment with GW3965, GW4064, or 1,25(OH)2D3 increased reporter activity ?2-, 5-, and 5.5-fold, respectively, from a construct containing mostly intron 1 of the SULT1C2 gene. Expression of AhR, LXR?, LXR?, PPAR?, PPAR?, PXR, and VDR was confirmed in LS180 cells using quantitative reverse-transcription polymerase chain reaction; however, FXR expression was negligible, suggesting that GW4064 increased SULT1C expression through an FXR-independent mechanism. Collectively, our findings are the first to characterize the regulation of human SULT1C2 and SULT1C3 expression by several transcription factor activators. Further, we determined that responsive regions for LXR and VDR are likely contained within intron 1 of the SULT1C2 gene.
