Introduction

Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the sulfate conjugation of phenolic compounds. Can also sulfonate estrogenic compounds, however, the dietary flavonoids (phytoestrogen) and environmental estrogens, like bisphenol A are better substrates than 17beta-estradiol (E2) (PubMed:17425406, PubMed:26948952, PubMed:28222028, PubMed:9852044). Mediates the sulfation of doxorubicin and its analog epirubicin, two antitumor anthracyclines (PubMed:26948952).

The cytosolic sulfotransferases (SULTs) are phase II conjugating enzymes, which are widely expressed in the liver and mainly mediate the sulfation of numerous xenobiotics and endogenous compounds. However, the role of various SULTs genes has not been reported in hepatocellular carcinoma (HCC). This study aims to analyze the expression and potential functional roles of SULTs genes in HCC and to identify the role of SULT2A1 in HCC stemness as well as the possible mechanism. We found that all of the 12 SULTs genes were differentially expressed in HCC. Moreover, clinicopathological features and survival rates were also investigated. Multivariate regression analysis showed that SULT2A1 and SULT1C2 could be used as independent prognostic factors in HCC. SULT1C4, SULT1E1, and SULT2A1 were significantly associated with immune infiltration. SULT2A1 deficiency in HCC promoted chemotherapy resistance and stemness maintenance. Mechanistically, silencing of SULT2A1 activated the AKT signaling pathway, on the one hand, promoted the expression of downstream stemness gene c-Myc, on the other hand, facilitated the NRF2 expression to reduce the accumulation of ROS, and jointly increased HCC stemness. Moreover, knockdown NR1I3 was involved in the transcriptional regulation of SULT2A1 in stemness maintenance. In addition, SULT2A1 knockdown HCC cells promoted the proliferation and activation of hepatic stellate cells (HSCs), thereby exerting a potential stroma remodeling effect. Our study revealed the expression and role of SULTs genes in HCC and identified the contribution of SULT2A1 to the initiation and progression of HCC.

AbstractCytosolic sulfotransferases (SULTs) are cytosolic enzymes that catalyze the transfer of sulfonate group to key endogenous compounds, altering the physiological functions of their substrates. SULT enzymes catalyze the O-sulfonation of hydroxy groups or N-sulfonation of amino groups of substrate compounds. In this study, we report the discovery of C-sulfonation of α,β-unsaturated carbonyl groups mediated by a new SULT enzyme, SULT7A1, and human SULT1C4. Enzymatic assays revealed that SULT7A1 is capable of transferring the sulfonate group from 3′-phosphoadenosine 5′-phosphosulfate to the α-carbon of α,β-unsaturated carbonyl-containing compounds, including cyclopentenone prostaglandins as representative endogenous substrates. Structural analyses of SULT7A1 suggest that the C-sulfonation reaction is catalyzed by a novel mechanism mediated by His and Cys residues in the active site. Ligand-activity assays demonstrated that sulfonated 15-deoxy prostaglandin J2 exhibits antagonist activity against the prostaglandin receptor EP2 and the prostacyclin receptor IP. Modification of α,β-unsaturated carbonyl groups via the new prostaglandin-sulfonating enzyme, SULT7A1, may regulate the physiological function of prostaglandins in the gut. Discovery of C-sulfonation of α,β-unsaturated carbonyl groups will broaden the spectrum of potential substrates and physiological functions of SULTs.

Analysis of evolutionary and functional features of the bullfrog SULT1 family

Article

Author: Yamauchi, Kiyoshi ; Sato, Kosuke ; Ishihara, Akinori

We identified the bullfrog Rana catesbeiana sulfotransferase 1 (SULT1) family from the BLAST search tool of the public databases based on the SULT1 families of Nanorana parkeri, Xenopus laevis, and Xenopus tropicalis as queries, revealing the characteristics of the anuran SULT1 family. The results showed that the anuran SULT1 family comprises six subfamilies, four of which were related to the mammalian SULT1 subfamily. Additionally, the bullfrog has two SULT1Cc subfamily members that are consistent with the characteristics of the expanded Xenopus SULT1C subfamily. Several members of the bullfrog SULT1 family were suggested to play important roles in sulfation during metamorphosis. Among these, cDNAs encoding SULT1Cc1 and SULT1Y1 were cloned, and the sulfation activity was analyzed using recombinant proteins. The affinity for 2-naphthol and 3'-phosphoadenosine 5'-phosphosulfate (PAPS) and the enzymatic reaction rate were higher in SULT1Cc1 than in SULT1Y1. Both the enzymes showed inhibitory effect of many thyroid hormones (THs) analogs on the sulfation of 2-naphthol. The potency of sulfation activities of SULT1Cc1 and SULT1Y1 against T₄ indicated their possible role in the intracellular T₄ clearance during metamorphosis.
