Abstract
Background Genetic polymorphisms have been associated with risk of anti-tuberculosis treatment toxicity. We characterized associations with adverse events and treatment failure/recurrence among adults treated for tuberculosis in Brazil. Methods Participants were followed in Regional Prospective Observational Research in Tuberculosis (RePORT)-Brazil. We included persons with culture-confirmed drug-susceptible pulmonary tuberculosis who started treatment between 2015-2019, and who were evaluable for pharmacogenetics. Treatment included 2 months of isoniazid, rifampin or rifabutin, pyrazinamide, and ethambutol, then 4 months of isoniazid and rifampin or rifabutin, with 24 month follow-up. Analyses included 43 polymorphisms in 20 genes related to anti-tuberculosis drug hepatotoxicity or pharmacokinetics. Whole exome sequencing was done in a case-control toxicity subset. Results Among 903 participants in multivariable genetic association analyses, NAT2 slow acetylator status was associated with increased risk of treatment-related grade 2 or greater adverse events, including hepatotoxicity. Treatment failure/recurrence was more likely among NAT2 rapid acetylators, but not statistically significant at the 5% level. A GSTM1 polymorphism (rs412543) was associated with increased risk of treatment-related adverse events, including hepatotoxicity. SLCO1B1 polymorphisms were associated with increased risk of treatment- related hepatoxicity and treatment failure/recurrence. Polymorphisms in NR1/2 were associated with decreased risk of adverse events and increased risk of failure/recurrence. In whole exome sequencing, hepatotoxicity was associated with a polymorphism in VTI1A , and the genes METTL17 and PRSS57 , but none achieved genome-wide significance. Conclusions In a clinical cohort representing three regions of Brazil, NAT2 acetylator status was associated with risk for treatment-related adverse events. Additional significant polymorphisms merit investigation in larger study populations.

Abstract
Sulfotransferases (SULTs) are Phase II drug-metabolizing enzymes (DMEs) catalyzing the sulfation of a variety of endogenous compounds, natural products, and drugs. Various drugs, such as nonsteroidal anti-inflammatory drugs (NSAIDS) can inhibit SULTs, affecting drug-drug interactions. Several polymorphisms have been identified for SULTs that might be crucial for interindividual variability in drug response and toxicity or for increased disease risk. Here, we review current knowledge on non-synonymous single nucleotide polymorphisms (nsSNPs) of human SULTs, focusing on the coded SULT allozymes and molecular mechanisms explaining their variable activity, which is essential for personalized medicine. We discuss the structural and dynamic bases of key amino acid (AA) variants implicated in the impacts on drug metabolism in the case of SULT1A1, as revealed by molecular modeling approaches.

Abstract
Cytosolic sulfotransferase SULT1C subfamily is one of the most flexible gene subfamilies during mammalian evolution. The physiological functions of SULT1C enzymes still remain to be fully understood. In this study, common marmoset (Callithrix jacchus), a promising primate animal model, was used to investigate the functional relevance of the SULT1C subfamily. Gene database search revealed 3 intact SULT1C genes and a pseudogene in its genome. These 4 genes were named SULT1C1, SULT1C2, SULT1C3P, and SULT1C5, according to the sequence homology and gene location. Since SULT1C5 is the orthologous gene for human SULT1C2P, we propose, here, to revisit the designation of human SULT1C2P to SULT1C5P. Purified recombinant SULT1C enzymes showed sulfating activities toward a variety of xenobiotic compounds and thyroid hormones. Kinetic analysis revealed high catalytic activities of SULT1C1 and SULT1C5 for 3,3'-T2. It appears therefore that SULT1C isoforms may play a role in the thyroid hormone metabolism in common marmoset.

Developmental Expression of SULT1C4 Transcript Variants in Human Liver: Implications for Discordance Between SULT1C4 mRNA and Protein Levels. Drug Metab Dispos 2020; 48:515-520. [PMID: 32303576 DOI: 10.1124/dmd.120.090829] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2020] [Accepted: 03/20/2020] [Indexed: 01/11/2023] Open
Abstract
The cytosolic sulfotransferases (SULTs) metabolize a variety of xenobiotic and endogenous substrates. Several SULTs are expressed in the fetus, implying that these enzymes have important functions during human development. We recently reported that while SULT1C4 mRNA is abundant in prenatal human liver specimens, SULT1C4 protein is barely detectable. Two coding transcript variants (TVs) of SULT1C4 are indexed in GenBank, TV1 (full-length) and TV2 (lacking exons 3 and 4). The purpose of this study was to evaluate expression of the individual TVs as a clue for understanding the discordance between mRNA and protein levels. Reverse-transcription polymerase chain reaction was initially performed to identify TVs expressed in intestinal and hepatic cell lines. This analysis generated fragments corresponding to TV1, TV2, and a third variant that lacked exon 3 (E3DEL). Using reverse-transcription quantitative polymerase chain reaction assays designed to quantify TV1, TV2, or E3DEL individually, all three TVs were more highly expressed in prenatal than postnatal specimens. TV2 levels were ∼fivefold greater than TV1, while E3DEL levels were minimal. RNA sequencing (RNA-seq) analysis of another set of liver specimens confirmed that TV1 and TV2 levels were highest in prenatal liver, with TV2 higher than TV1. RNA-seq also detected a noncoding RNA, which was also more abundant in prenatal liver. Transfection of HEK293T cells with plasmids expressing individual Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys-tagged SULT1C4 isoforms demonstrated that TV1 produced much more protein than did TV2. These data suggest that the lack of correspondence between SULT1C4 mRNA and protein levels in human liver is likely attributable to the inability of the more abundant TV2 to produce stable protein. SIGNIFICANCE STATEMENT: Cytosolic sulfotransferases (SULTs) metabolize a variety of xenobiotic and endogenous substrates, and several SULTs are highly expressed in the fetus, implying that they have important functions during human development. SULT1C4 is highly expressed in prenatal liver at the mRNA level but not the protein level. This study provides an explanation for this discordance by demonstrating that the predominant SULT1C4 transcript is a variant that produces relatively little protein.

Abstract
Cytosolic sulfotransferases (SULTs) are expressed during early life and therefore metabolize endogenous and xenobiotic chemicals during development. Little is currently known about the regulation of individual SULTs in the developing human liver. We characterized SULT expression in primary cultures of human fetal hepatocytes and the HepaRG model of liver cell differentiation. SULT1A1 (transcript variants 1-4), SULT1C2, SULT1C4, SULT1E1, and SULT2A1 were the most abundant transcripts in human fetal hepatocytes. In HepaRG cells, SULT1B1, SULT1C2/3/4, and SULT1E1 mRNA levels increased during the transition from proliferation to confluency and then decreased as the cells underwent further differentiation. By contrast, SULT2A1 mRNA levels increased during differentiation, whereas SULT1A1 and SULT2B1 mRNA levels remained relatively constant. The temporal patterns of SULT1C2, SULT1E1, and SULT2A1 protein content were consistent with those observed at the mRNA level. To identify regulators of SULT expression, cultured fetal hepatocytes and HepaRG cells were treated with a panel of lipid- and xenobiotic-sensing receptor activators. The following effects were observed in both fetal hepatocytes and HepaRG cells: 1) liver X receptor activator treatment increased SULT1A1 transcript variant 5 levels; 2) vitamin D receptor activator treatment increased SULT1C2 and SULT2B1 mRNA levels; and 3) farnesoid X receptor activator treatment decreased SULT2A1 expression. Activators of aryl hydrocarbon receptor, constitutive androstane receptor, pregnane X receptor, and peroxisome proliferator-activated receptors produced additional gene-dependent effects on SULT expression in HepaRG cells. These findings suggest that SULT-regulating chemicals have the potential to modulate physiologic processes and susceptibility to xenobiotic stressors in the developing human liver.

Abstract
Sulfonation is one of the most abundant cellular reactions modifying a wide range of xenobiotics as well as endogenous molecules which regulate important biological processes including blood clotting, formation of connective tissues, and functionality of secreted proteins, hormones, and signaling molecules. Sulfonation is ubiquitous in all tissues and widespread in nature (plants, animals, and microorganisms). Although sulfoconjugates were discovered over a century ago when, in 1875, Baumann isolated phenyl sulfate in the urine of a patient given phenol as an antiseptic, the significance of sulfonation and its roles in human diseases have been underappreciated until recent years. Here, we provide a current overview of the significance of sulfonation reactions in a variety of biological functions and medical conditions (with emphasis on cancer). We also discuss research areas that warrant further attention if we are to fully understand how deficiencies in sulfonation could impact human health which, in turn, could help define treatments to effect improvements in health.

Abstract
The cytosolic sulphotransferase SULT1C3 remained the most poorly understood human SULT. The SULT1C3 gene has been shown to contain alternative exons 7 and 8, raising the question concerning their evolutionary origin and implying the generation of multiple SULT1C3 variants. Two SULT1C3 splice variants, SULT1C3a and SULT1C3d, were investigated to verify the impact of alternative C-terminal sequences on their sulphating activity. Sequence homology and gene location analyses were performed to verify the orthology of the SULT1C3 gene. The SULT1C3 gene appears to be present only in humans and other primates, but alternative exons 7b and 8b share high degrees of homology with corresponding regions of rodent SULT1C1 genes, implying their evolutionary origin being from a defunct human SULT1C1 gene. Purified recombinant SULT1C3a and SULT1C3d were analyzed for sulphating activities toward a variety of endogenous and xenobiotic compounds. While SULT1C3a displayed weaker activities and strict substrate specificity toward hydroxyl-chlorinated biphenyls, SULT1C3d exhibited broader substrate specificity toward bile acids and thyroid hormones as well as hydroxyl-chlorinated biphenyls. Molecular docking simulation suggested that Tyr249 and Met257 may play an important role in substrate recognition by SULT1C3d. Alternative splicing of exons 7 and 8 sequences resulted in differential catalytic properties of SULT1C3 variants.

Abstract
Estrus expression by gilts and sows is hereditable and important for heat detection. To better understand the molecular biological mechanisms of estrus expression in gilts, the mRNA expression profiles of follicular tissue from Large White gilts in diestrus (LD, n = 3) and estrus (LE, n = 3), and Chinese indigenous Mi gilts in diestrus (MD, n = 2) and estrus (ME, n = 3) were investigated using RNA sequencing. We detected 122,804-335,295 SNPs, 6,140-14,947 InDel and 12 types of AS events (39.57% TSS, 34.90% TTS) in 11 samples. A total of 2,838 differentially expressed genes (DEGs) were found in LD vs MD, LE vs ME, LE vs LD, or ME vs MD comparisons. Two DEGs (ACP5 and PIGS) were observed in all comparisons. Two new genes (ENSSSCG00000028235 and ENSSSCG00000021903) were exclusively expressed in Mi and Large White gilts, respectively. Bioinformatics analyses indicate that these DEGs are involved in single-organism process, catalytic activity, cell adhesion and enriched in ECM-receptor interaction, olfactory transduction, ovarian steroidogenesis, steroid biosynthesis and CAMs signaling pathways. These results of RNA-Seq have provided important information for screening the key functional genes or molecular markers of estrus expression in gilts.

Abstract
Cytosolic sulfotransferase 1C3 (SULT1C3) is the least characterized of the three human SULT1C subfamily members. Originally identified as an orphan SULT by computational analysis of the human genome, we recently reported that SULT1C3 is expressed in human intestine and LS180 colorectal adenocarcinoma cells and is upregulated by agonists of peroxisome proliferator-activated receptor (PPAR) α and γ To determine the mechanism responsible for PPAR-mediated upregulation, we prepared reporter plasmids containing fragments of the SULT1C3 5'-flanking region. During initial attempts to amplify a 2.8-kb fragment from different sources of human genomic DNA, a 1.9-kb fragment was sometimes coamplified with the expected 2.8-kb fragment. Comparison of the 1.9-kb fragment sequence to the published SULT1C3 5'-flanking sequence revealed an 863-nt deletion (nt -146 to -1008 relative to the transcription start site). Transfection analysis in LS180 cells demonstrated that PPARα, δ, and γ agonist treatments induced luciferase expression from a reporter plasmid containing the 2.8-kb but not the 1.9-kb fragment. The PPAR agonists also activated a 1-kb reporter containing the 863-nt deletion region. Computational analysis identified three peroxisome proliferator response elements (PPREs) within the 863-nt region and serial deletions and site-directed mutations indicated that the most distal PPRE (at nt -769) was essential for obtaining PPAR-mediated transcriptional activation. Although agonists of all three PPARs could activate SULT1C3 transcription, RNA interference analysis indicated the predominance of PPARγ These data demonstrate that the PPARγ regulatory network includes SULT1C3 and imply that this enzyme contributes to the control of such PPARγ-regulated intestinal processes as growth, differentiation, and metabolism.

Abstract
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. 1α,25-Dihydroxyvitamin D3 [1,25(OH)2D3, vitamin D receptor (VDR)] selectively upregulated SULT1C2, whereas ciprofibrate [peroxisome proliferator-activated receptor α (PPARα)], rosiglitazone (PPARγ), 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, LXRα, LXRβ, PPARα, PPARγ, 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.
