Abstract
We established myocardial injury models in vivo and in vitro to investigate the cardioprotective effect of gomisin D obtained from Schisandra chinensis. Gomisin D significantly inhibited isoproterenol-induced apoptosis and hypertrophy in H9C2 cells. Gomisin D decreased serum BNP, ANP, CK-MB, cTn-T levels and histopathological alterations, and inhibited myocardial hypertrophy in mice. In mechanisms research, gomisin D reversed ISO-induced accumulation of intracellular ROS and Ca2+. Gomisin D further improved mitochondrial energy metabolism disorders by regulating the TCA cycle. These results demonstrated that gomisin D had a significant effect on isoproterenol-induced myocardial injury by inhibiting oxidative stress, calcium overload and improving mitochondrial energy metabolism.

Tian Y, Zhang Z, Yan A. Discovering the Active Ingredients of Medicine and Food Homologous Substances for Inhibiting the Cyclooxygenase-2 Metabolic Pathway by Machine Learning Algorithms. Molecules 2023; 28:6782. [PMID: 37836625 PMCID: PMC10574661 DOI: 10.3390/molecules28196782] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Revised: 09/20/2023] [Accepted: 09/21/2023] [Indexed: 10/15/2023] Open
Abstract
Cyclooxygenase-2 (COX-2) and microsomal prostaglandin E2 synthase (mPGES-1) are two key targets in anti-inflammatory therapy. Medicine and food homology (MFH) substances have both edible and medicinal properties, providing a valuable resource for the development of novel, safe, and efficient COX-2 and mPGES-1 inhibitors. In this study, we collected active ingredients from 503 MFH substances and constructed the first comprehensive MFH database containing 27,319 molecules. Subsequently, we performed Murcko scaffold analysis and K-means clustering to deeply analyze the composition of the constructed database and evaluate its structural diversity. Furthermore, we employed four supervised machine learning algorithms, including support vector machine (SVM), random forest (RF), deep neural networks (DNNs), and eXtreme Gradient Boosting (XGBoost), as well as ensemble learning, to establish 640 classification models and 160 regression models for COX-2 and mPGES-1 inhibitors. Among them, ModelA_ensemble_RF_1 emerged as the optimal classification model for COX-2 inhibitors, achieving predicted Matthews correlation coefficient (MCC) values of 0.802 and 0.603 on the test set and external validation set, respectively. ModelC_RDKIT_SVM_2 was identified as the best regression model based on COX-2 inhibitors, with root mean squared error (RMSE) values of 0.419 and 0.513 on the test set and external validation set, respectively. ModelD_ECFP_SVM_4 stood out as the top classification model for mPGES-1 inhibitors, attaining MCC values of 0.832 and 0.584 on the test set and external validation set, respectively. The optimal regression model for mPGES-1 inhibitors, ModelF_3D_SVM_1, exhibited predictive RMSE values of 0.253 and 0.35 on the test set and external validation set, respectively. Finally, we proposed a ligand-based cascade virtual screening strategy, which integrated the well-performing supervised machine learning models with unsupervised learning: the self-organized map (SOM) and molecular scaffold analysis. Using this virtual screening workflow, we discovered 10 potential COX-2 inhibitors and 15 potential mPGES-1 inhibitors from the MFH database. We further verified candidates by molecular docking, investigated the interaction of the candidate molecules upon binding to COX-2 or mPGES-1. The constructed comprehensive MFH database has laid a solid foundation for the further research and utilization of the MFH substances. The series of well-performing machine learning models can be employed to predict the COX-2 and mPGES-1 inhibitory capabilities of unknown compounds, thereby aiding in the discovery of anti-inflammatory medications. The COX-2 and mPGES-1 potential inhibitor molecules identified through the cascade virtual screening approach provide insights and references for the design of highly effective and safe novel anti-inflammatory drugs.

Ageing Res Rev 2023; 90:102029. [PMID: 37549873 DOI: 10.1016/j.arr.2023.102029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Accepted: 08/04/2023] [Indexed: 08/09/2023]
Abstract
BACKGROUND Dementia is prevalent in aged populations and is associated with disability and distress for those affected. Therapeutic benefits of drugs targeting dementia are small. Impaired nutrient sensing pathways have been implicated in the pathogenesis of dementia and may offer a novel treatment target. AIMS This systematic review collated evidence for novel therapeutic compounds that modify nutrient sensing pathways, particularly the sirtuin pathway, in preventing cognitive decline or improving cognition in normal ageing, mild cognitive impairment (MCI), and dementia. METHODS PubMed, Embase and Web of Science databases were searched using key search terms. Articles were screened using Covidence systematic review software. The risk of bias was assessed using the Systematic Review Center for Laboratory animal Experimentation (SYRCLE)'s risk of bias tool for animal studies and Cochrane Risk of Bias tool v 2.0 for human studies. RESULTS Out of 3841 articles, 68 were included describing 38 different novel therapeutic compounds that modulate the nutrient sensing pathway via the sirtuin pathway. In animal models (58 studies), all investigated novel therapeutic compounds showed cognitive benefits. Ten studies were human intervention trials targeting normal ageing (1 study) and dementia populations (9 studies). Direct sirtuin (silent mating type information regulation 2 homolog) 1 (SIRT1) activators Resveratrol and Nicotinamide derivatives improved cognitive outcomes among human subjects with normal cognition and MCI. CONCLUSION Animal studies support that modulation of the sirtuin pathway has the potential to improve cognitive outcomes. Overall, there is a clear lack of translation from animal models to human populations.

[PMID: 36822287 DOI: 10.1016/j.ijbiomac.2023.123639] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Revised: 02/03/2023] [Accepted: 02/07/2023] [Indexed: 02/25/2023]
Abstract
Platelet-derived growth factor receptor β (PDGFRβ) plays an important role in hepatic fibrosis and is closely associated with hepatic stellate cells (HSCs) activation. Previously, by modeling PDGFRβ affinity chromatography, we found that gomisin D can target PDGFRβ. However, whether gomisin D has anti-fibrosis effects through targeting PDGFRβ remained unclear. In this study, the effect of gomisin D on hepatic fibrosis was evaluated in vivo and vitro. HSC cell lines and primary HSC were cultured and functionally we found that gomisin D promotes HSC apoptosis, inhibits HSCs activation and proliferation. A male BALB/c mouse liver fibrosis model was established to comfirm gomisin D (especially in 50 mg/kg) could improve liver fibrosis by inhibiting HSCs activation. In addition, gomisin D had a good binding ability with PDGFRβ (KD = 3.3e-5 M). Mechanically, gomisin D regulated PDGF-BB/PDGFRβ signaling pathway by targeting PDGFRβ, further more inhibited HSC activation, subsequently inhibited inflammatory factors, ultimately improved CCl4-induced liver fibrosis. Overall, gomisin D could inhibit HSC proliferation and activation, promote HSC apoptosis, and alleviate CCl4-induced hepatic fibrosis by targeting PDGFRβ and regulating PDGF-BB/PDGFRβ signaling pathway. This study provides a new drug for anti-liver firbosis therapy, and elucidates the deeper mechanism of gomisin D against HSCs activation by targeting PDGFRβ.

Metabolic profiling on the analysis of different parts of Schisandra chinensis based on UPLC-QTOF-MS with comparative bioactivity assays. FRONTIERS IN PLANT SCIENCE 2022; 13:970535.

Abstract
The Schisandra chinensis is an important edible plant, and previous phytochemical research focused on the S. chinensis fruit (SF) due to its long history as traditional Chinese medicine. Schisandra chinensis fruit was used as an astringent tonic to astringe the lungs and the kidneys, replenish energy, promote the production of body fluids, tonify the kidney, and induce sedation. The components of S. chinensis, such as its stems (SS), leaves (SL), and roots (SR), have drawn little attention regarding their metabolites and bioactivities. In this study, a strategy of combining a chemical database with the Progenesis QI informatics platform was applied to characterize the metabolites. A total of 332 compounds were tentatively identified, including lignans, triterpenoids, flavonoids, tannins, and other compound classes. Heatmap and principal component analysis (PCA) showed remarkable differences in different parts of the plants. By multiple orthogonal partial least-squares discriminant analyses (OPLS-DA), 76 compounds were identified as potential marker compounds that differentiate these different plant parts. Based on the variable influence on the projection score from OPLS-DA, the active substances including gomisin D, schisandrol B, schisantherin C, kadsuranin, and kadlongilactone F supported the fact that the biological activity of the roots was higher than that of the fruit. These substances can be used as marker compounds in the plant roots, which likely contribute to their antioxidant and anti-inflammatory activities. The plant roots could be a new medicinal source that exhibits better activity than that of traditional medicinal parts, which makes them worth exploring.

JOURNAL OF ETHNOPHARMACOLOGY 2022; 296:115461. [PMID: 35728710 DOI: 10.1016/j.jep.2022.115461] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 06/11/2022] [Accepted: 06/11/2022] [Indexed: 06/15/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The liver damage associated with Polygonum multiflorum Thunb. (P. multiflorum) and its preparations have aroused widespread concern. Opinions on the toxicity mechanisms and targets of P. multiflorum vary, and the toxic components are even more controversial. However, based on the current research results, we believed that any single component in P. multiflorum could not directly lead to liver injury, but may be the synergistic effect of multiple components. In addition, the toxicity mechanism also involved multiple targets. AIM OF THE STUDY This study aimed to elucidate the mechanism and target of the hepatotoxicity of P. multiflorum. MATERIALS AND METHODS In this study, the manifestations of liver injury triggered by P. multiflorum and the associated metabolic enzymes/transporters in the metabolic pathways of bilirubin and bile acid were investigated to elucidate the mechanism and target of the hepatotoxicity of P. multiflorum and related components. First, the hepatotoxicity and potential effect of P. multiflorum on both metabolic pathways were studied in rats administered P. multiflorum extracts (in 70% ethanol) for 42 days. Then, in vitro cultured hepatocyte spheroids were used to determine the hepatotoxicity of monomer components. RESULTS This revealed that P. multiflorum could simultaneously block bilirubin(BIL) and bile acid(BA) metabolism pathways, subsequently leading to liver damage. The targets and modes of action include reducing the activity of UGT1A1, the only metabolic enzyme of BIL, downregulating BIL and BA uptake transporters NTCP, OATP1B1, OATP1B3, efflux transporters MRP2, and BSEP, and upregulating efflux transporter MRP3. Furthermore, our data indicated that 2,3,5,4'-tetrahydroxystilbene-2-O-β-glucoside (TSG) and emodin-8-O-β-D-glucoside (EG) are the main toxic components in P. multiflorum. TSG accounts for 3.71% of the total content of P. multiflorum. In addition to markedly downregulating UGT1A1, TSG can upregulate OATP1B1/3 and promote the uptakes of bilirubin and bile acid, producing synergistic toxicity. EG accounts for 0.29% of the total content and demonstrates direct hepatotoxicity and extensive substrate overlap with bilirubin and bile acids. It can affect these two metabolic pathways simultaneously, promoting the accumulation of both bilirubin and bile acid for further toxic effects. Emodin is other major component, accounting for 0.01% of the total content, and its hepatotoxicity mechanisms include direct toxicity and inhibitory effects on bilirubin metabolizing enzymes. However, emodin is mainly distributed in the kidneys, so its hepatotoxicity risk is relatively low. CONCLUSION The simultaneous blockade of bilirubin and bile acid metabolic pathways as the critical toxic mechanism of P. multiflorum-induced liver injury, and potential toxic components were TSG and EG.

Abstract
Human UDP-glucuronosyltransferase (UGT) 2B7 is a crucial phase II metabolic enzyme that transfers glucuronic acid from UDP-glucuronic acid (UDPGA) to endobiotic and xenobiotic substrates. Biophysical and biochemical investigations of UGT2B7 are hampered by the challenge of the integral membrane protein purification. This study focused on the expression and purification of recombinant UGT2B7 by optimizing the insertion sites for the thermostabilized fusion protein apocytochrome b562RIL (BRIL) and various mutations to improve the protein yields and homogeneity. Preparation of the recombinant proteins with high purity accelerated the measurement of pharmacokinetic parameters of UGT2B7. The dissociation constants (KD) of two classical substrates (zidovudine and androsterone) and two inhibitors (schisanhenol and hesperetin) of UGT2B7 were determined using the surface plasmon resonance spectroscopy (SPR) for the first time. Using negative-staining transmission electron microscopy (TEM), UGT2B7 protein particles were characterized, which could be useful for further exploring its three-dimensional structure. The methods described in this study could be broadly applied to other UGTs and are expected to provide the basis for the exploration of metabolic enzyme kinetics, the mechanisms of drug metabolisms and drug interactions, changes in pharmacokinetics, and pharmacodynamics studies in vitro.

Abstract
The liver injury induced by Polygonum multiflorum root (PMR) is an urgent issue requiring wide spread attention. UDP-glucuronosyltransferase 1A1 (UGT1A1) inhibitors are suspected to additively contribute to the hepatotoxicity of PMR. This study was deliberately designed to simultaneously screen the UGT1A1 inhibitors from PMR and their co-contribution to the hepatotoxicity was evaluated. With ultrafiltration coupled to liquid chromatography-mass spectrometry method, four compounds namely cis-2,3,5,4'-tetrahydroxystilbene-2-O-β-glucoside, trans-2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside, emodin-8-O-β-D-glucoside and emodin were screened out, displaying the in vitro inhibitory activities against UGT1A1 with IC50 values of 76.23, 18.70, 62.18, 34.02 μM, respectively. The varying activities of screened UGT1A1 inhibitors were explained by performing a molecular docking simulation. Finally, zebrafish larvae and mice assays demonstrated that the UGT1A1 inhibitors co-contributed to the hepatotoxicity of PMR. Hopefully, these findings are conducive to understand the acting role of UGT1A1 inhibitors in PMR-induced hepatotoxicity.

Abstract
A variety of environmental toxicants such as heavy metals, pesticides, organic
chemicals, etc produce harmful effects in our living systems. In the literature, various reports have
indicated the detrimental effects of toxicants such as immunotoxicity, cardiotoxicity,
nephrotoxicity, etc. Experimental animals are generally used to investigate the safety profile of
environmental chemicals, but research on animals has some limitations. Thus, there is a need for
alternative approaches. Docking study is one of the alternate techniques which predict the binding
affinity of molecules in the active site of a particular receptor without using animals. These
techniques can also be used to check the interactions of environmental toxicants towards biological
targets. Varieties of user-friendly software are available in the market for molecular docking, but
very few toxicologists use these techniques in the field of toxicology. To increase the use of these
techniques in the field of toxicology, understanding of basic concepts of these techniques is
required among toxicological scientists. This article has summarized the fundamental concepts of
docking in the context of its role in toxicology. Furthermore, these promising techniques are also
discussed in this study.

Abstract
Gomisin D, a lignan compound isolated from Fructus Schisandra, is a potential antidiabetic and anti-Alzheimer’s agent. Recently, gomisin D was used as a quality marker of some traditional Chinese medicine (TCM) formulas. In this study, a rapid ultra-performance liquid chromatography/tandem mass spectrometry method (UPLC-MS/MS) was developed and validated to quantify gomisin D in rat plasma for a pharmacokinetic and bioavailability study. Acetonitrile was used to precipitate plasma proteins. Separations were performed on a BEH C18 column with a gradient mobile phase comprising of acetonitrile and water (0.1% formic acid). An electrospray ionization source was applied and operated in the positive ion mode. The multiple reaction monitoring mode (MRM) was utilized to quantify gomisin D and nomilin (internal standard, IS) using the transitions of m/z 531.2 → 383.1 and m/z 515.3 → 161.0, respectively. The calibration curve was linear over the working range from 1 to 4000 ng/mL (R2 = 0.993). The intra- and interday precision ranged from 1.9% to 12.9%. The extraction recovery of gomisin D was in the range of 79.2–86.3%. The validated UPLC-MS/MS method was then used to obtain the pharmacokinetic characteristics of gomisin D after intravenous (5 mg/kg) and intragastric (50 mg/kg) administration to rats. The bioavailability of gomisin D was 107.6%, indicating that this compound may become a promising intragastrical medication. Our results provided useful information for further preclinical studies on gomisin D.

J Food Drug Anal 2019; 27:284-294. [PMID: 30648582 PMCID: PMC9298630 DOI: 10.1016/j.jfda.2018.10.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2018] [Revised: 10/12/2018] [Accepted: 10/22/2018] [Indexed: 12/25/2022] Open
Abstract
The traditional Chinese herbal formula Shenmai-Yin (SY) and nifedipine have both been used to treat patients with cardiovascular disorders. Nifedipine is primarily oxidized by cytochrome P450 (CYP) 3A. The oxidation and pharmacokinetics of nifedipine were studied in rats in vitro and in vivo to illustrate the interaction of SY with nifedipine. Schisandrol A, schisandrin A and schisandrin B were identified as the main lignans in SY. In the study in vitro, the ethanolic extract of SY was used due to the solubility and the extract inhibited nifedipine oxidation (NFO) activity in a time-dependent manner. Among lignans, schisandrin B caused the most potent inhibition. According to the time-dependent inhibition behavior, rats were treated with SY 1 h before nifedipine administration. After oral treatment with 1.9 g/kg SY, nifedipine clearance decreased by 34% and half-life increased by 142%. SY treatment decreased hepatic NFO activity by 49%. Compared to the change caused by ketoconazole, the SY-mediated reduction of nifedipine clearance was moderate. These findings demonstrate that SY causes a time-dependent inhibition of NFO and schisandrin B contributes to the inhibition. The decreased nifedipine clearance by SY in rats warrants further human study to examine the clinical impact of this decrease.

Abstract
Traditional Chinese medicine (TCM) preparations have significant effects on some refractory diseases; however, these compositions are complex and their mechanisms are unknown. Identification of the active components in these preparations is essential. The mortality rate for heart failure (HF) has been increasing in recent years, and myocardial dysfunction (MD) has been proved to be the pathological basis of HF. Yixinshu Capsule (YXSC) is a multi-component oral drug with therapeutic effects on HF. However, the key active components are still unclear. In this study, YXSC intestinal absorption liquid (IAL) was used and 62 compounds were identified by an analytical chemistry approach. Then, a compound - target - function network was established with a bioinformatics analysis tool. Finally, a cell model of MD on human-induced pluripotent stem cell-derived cardiomyocytes (hiPS-CMs) was used to verify the therapeutic effects of the active components of YXSC. Schisandrin A (Sch A) and schisandrin B (Sch B) were demonstrated to be the active components of YXSC by attenuating endothelin-1 (ET-1)-induced contraction dysfunction, brain natriuretic peptide (BNP) content elevation, and the morphological changes of hiPS-CMs. For the first time, our data illustrate the potent protective effects of Sch A and Sch B on ET-1-induced dysfunctional hiPS-CMs and revealed their effective targets and pathways. The integrative approach used in our study was applied to identify active components in TCM preparations and excavate the possible mechanisms.

Abstract
Berberrubine (BRB) has a strong lipid-lowering effect and can be extensively metabolized into berberrubine-9-O-β-d-glucuronide (BRBG) in vivo. Recently, pharmacokinetics studies showed that the production of BRBG was significantly decreased in the urine of mice fed with a high-fat diet (HFD), indicating a decreased glucuronidation capacity. Based on the UDP-glucuronosyltransferase (UGT) isoform identification, hepatic and renal microsomal incubation, glucuronidation was examined to suggest the metabolism of BRB in liver and kidneys. The results showed that the renal UGT activity for metabolizing BRB markedly decreased, which may be highly related to the decreased expression and activity of renal Ugt1a7c. Surprisingly, in vitro studies revealed neither BRB nor BRBG inhibited the renal UGT activity. By employing an integrated strategy of metabolomics and pharmacokinetics, we identified and confirmed for the first time the inhibitory effect of some potential endogenous molecules on the renal glucuronidation of C57BL/6J mice, such as glutaric acid (GA) and linoleic acid (LA). By employing recombinant human UGTs, we found that GA and LA efficiently affect the activity of recombinant human UGT1A7, 1A9, and 1A8 at their normal or abnormal physiologic levels in vivo. GA (2 mM) markedly inhibited the activity of UGT1A7 by 89.4% and UGT1A9 by 32.8%. The inhibition rates reached 99.3% for UGT1A9, 48.3% for UGT1A7, and 46.8% for UGT1A8 with LA at 200 μM. It has been suggested that the endogenous molecules have the potential to affect the efficiency of glucuronidation, which might be a key factor contributing to individual differences in drug metabolism.

Identification and characterization of the structure-activity relationships involved in UGT1A1 inhibition by anthraquinone and dianthrone constituents of Polygonum multiflorum. Sci Rep 2017; 7:17952. [PMID: 29263357 PMCID: PMC5738440 DOI: 10.1038/s41598-017-18231-y] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2017] [Accepted: 12/07/2017] [Indexed: 12/29/2022] Open
Abstract
The adverse effects of Polygonum (P.) multiflorum, including abnormal bilirubin metabolism, are a serious public health issue. As uridine diphosphate (UDP)-glucuronosyltransferase 1A1 (UGT1A1) is the only enzyme responsible for bilirubin metabolism, we investigated the inhibitory effect of a P. multiflorum extract and 10 anthraquinone and dianthrone compounds on UGT1A1 in rat liver microsomes in vitro. The P. multiflorum extract exhibited the strongest inhibitory effect on UGT1A1 activity (inhibition constant [Ki] = 0.3257 μM, 1422 μg of material/mL), followed by cis-emodin dianthrones (Ki = 0.8630 μM), trans-emodin dianthrones (Ki = 1.083 μM), emodin-8-O-glc (Ki = 3.425 μM), and polygonumnolide C2 (Ki = 4.291 μM). Analysis of the structure–activity relationships of these compounds suggested that the spatial orientation of the molecules and the presence of particular functional groups affect UGT1A1 inhibition. A mechanistic analysis showed that all the tested compounds docked into two of the nine active sites of UGT1A1 and suggested that hydrophobic interactions and hydrogen bonds are important for the affinity of the tested compounds for UGT1A1; moreover, their interaction energies were generally in agreement with the Ki values. These findings provide insight into adverse reactions to P. multiflorum and identify the pharmacophores involved in inhibition of UGT1A1.

Abstract
Mammalian UDP-glucuronosyltransferases (UGTs) catalyze the transfer of glucuronic acid from UDP-glucuronic acid to various xenobiotics and endobiotics. Since UGTs comprise rate-limiting enzymes for metabolism of various compounds, co-administration of UGT-inhibiting drugs and genetic deficiency of UGT genes can cause an increased blood concentration of these compounds. During the last few decades, extensive efforts have been made to advance the understanding of gene structure, function, substrate specificity, and inhibition/induction properties of UGTs. However, molecular mechanisms and physiological importance of the oligomerization and protein–protein interactions of UGTs are still largely unknown. While three-dimensional structures of human UGTs can be useful to reveal the details of oligomerization and protein–protein interactions of UGTs, little is known about the protein structures of human UGTs due to the difficulty in solving crystal structures of membrane-bound proteins. Meanwhile, soluble forms of plant and bacterial UGTs as well as a partial domain of human UGT2B7 have been crystallized and enabled us to predict three-dimensional structures of human UGTs using a homology-modeling technique. The homology-modeled structures of human UGTs do not only provide the detailed information about substrate binding or substrate specificity in human UGTs, but also contribute with unique knowledge on oligomerization and protein–protein interactions of UGTs. Furthermore, various in vitro approaches indicate that UGT-mediated glucuronidation is involved in cell death, apoptosis, and oxidative stress as well. In the present review article, recent understandings of UGT protein structures as well as physiological importance of the oligomerization and protein–protein interactions of human UGTs are discussed.
