Inhibition of human glutathione transferase by catechin and gossypol: comparative structural analysis by kinetic properties, molecular docking and their efficacy on the viability of human MCF-7 cells. J Biochem 2023; 175:69-83. [PMID: 37787553 DOI: 10.1093/jb/mvad070] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Revised: 09/05/2023] [Accepted: 09/18/2023] [Indexed: 10/04/2023] Open
Abstract
Glutathione transferase Pi (GSTP1) expression is increased in many cancer types and is associated with multidrug resistance and apoptosis inhibition. Inhibitors of GSTP1-1 have the potential to overcome drug resistance and improve chemotherapy efficacy as adjuvant agents. This study investigated the effects of catechin and gossypol on human glutathione transferase Pi (GSTP1-1) activity and their cytotoxic effects on breast cancer cells (MCF-7) individually and in combination with tamoxifen (TAM). Gossypol effectively inhibited the enzyme with an IC50 value of 40 μM, compared to 200 μM for catechin. Gossypol showed stronger inhibition of GSTP1-1 activity (Ki = 63.3 ± 17.5 μM) compared to catechin (Ki = 220 ± 44 μM). Molecular docking analysis revealed their binding conformations to GSTP1-1, with gossypol binding at the subunit interface in an un-competitive manner and catechin showing mixed non-competitive inhibition. Gossypol had severe cytotoxic effects on both MCF-7 cells and normal BJ1 cells, while catechin had a weak cytotoxic effect on MCF-7 cells only. Combination therapy with TAM resulted in cytotoxicity of 27.3% and 35.2% when combined with catechin and gossypol, respectively. Gossypol showed higher toxicity to MCF-7 cells, but its strong effects on normal cells raised concerns about selectivity and potential side effects.

Abstract
INTRODUCTION Helicobacter pylori infection is accepted as the leading cause of chronic gastritis, ulcer disease and gastric cancer, with an important impact on health care burden, especially in countries with a high prevalence of infection. The aim of the study was to investigate the influence of H. pylori infection, medication, associated medical conditions or social habits on endoscopic ulcer occurrence in the compensated type 2 diabetic population. MATERIAL AND METHODS Two hundred and sixty type 2 diabetic patients investigated on endoscopy (57 patients with peptic ulcer and 203 controls) with a complete set of biopsies, demographic and medical data were enrolled. RESULTS On univariate regression analysis, H. pylori infection (42.1% vs. 35.5%, p = 0.359) or a history of peptic ulcer (61.4% vs. 61.6%, p = 0.981) was not a predictor for ulcer on endoscopy in the diabetic population, and heartburn was more frequent in diabetics without ulcer (21.2% vs. 8.8%, p = 0.033). Anemia was the best predictor for ulcer on endoscopy in both diabetics with (p < 0.001, OR = 4.77, 95% CI: 2.02-11.28) and without (p = 0.027, OR = 2.76, 95% CI: 1.10-6.91) chronic proton pump inhibitor (PPI) therapy. In diabetic patients on PPI more than 1 month anticoagulants - acenocoumarol or low-weight molecular heparin (p = 0.038, OR = 2.37, 95% CI: 1.04-5.40), low-dose aspirin 75-125 mg/day (p = 0.029, OR = 2.61, 95% CI: 1.08-6.28) and alcohol consumption (p = 0.015, OR = 2.70, 95% CI: 1.19-6.13) were predictors for ulcer on endoscopy. CONCLUSIONS In diabetic patients, anemia is the most important predictor for ulcer on endoscopy, but not H. pylori or digestive symptoms, while low-dose aspirin or anticoagulant therapy and alcohol consumption are the most important predictors for ulcer in diabetics on chronic proton pump inhibitor therapy.

Abstract
Patients exposed to pollutants are more likely to suffer from allergic rhinitis and may benefit from antioxidant treatment. Our study determined if patients diagnosed with grass-induced allergic rhinitis could benefit from broccoli sprout extract (BSE) supplementation. In total, 47 patients were confirmed with grass-induced allergic rhinitis and randomized to one of four groups: group 1 (nasal steroid spray + BSE), group 2 (nasal steroid spray + placebo tablet), group 3 (saline nasal spray + BSE) and group 4 (saline nasal spray + placebo tablet). Peak Nasal Inspiratory Flow (PNIF), Total Nasal Symptoms Scores (TNSS) and nasal mucus cytokine levels were analyzed in samples collected before and after the 3-week intervention. Comparing before and after the intervention, PNIF improved significantly when comparing Groups 1 and 2, vs. placebo, at various time points (p ≤ 0.05 at 5, 15, 60 and 240 min) following nasal challenge, while TNSS was only statistically significant at 5 (p = 0.03), 15 (p = 0.057) and 30 (p = 0.05) minutes. There were no statistically significant differences in various cytokine markers before and after the intervention. Combining nasal corticosteroid with BSE led to the most significant improvement in objective measures.

Abstract
Background: Vesicoureteral reflux (VUR) disease is the most common type of urinary tract anomalies in children. Genetic risk factors may be associated with the etiology of VUR. The role of the Glutathione S-transferases (GSTs) as multifunctional enzymes is cellular oxidative stress handling. This is the first study aimed at evaluating the relative risk of GSTP1, GSTM1, and GSTT1 polymorphisms in VUR susceptibility in children and provides new important insights into the genetics of affected children. Methods: The study was done in 2013 in Sistan and Baluchestan University, eastern Iran. Genotyping of three GSTP1, GSTM1, and GSTT1 genes were determined using the multiplex polymerase chain reaction assay in 216 reactions for 72 VUR children and 312 reactions for 104 healthy controls. Results: The presence of GSTT1 deletion was associated with high risk of VUR in children, whereas GSTP1 and GSTM1 genotypes did not show the same effect. Furthermore, the combination of GSTT1/GSTM1 and GSTT1/ GSTP1 genotypes showed a significant influence on lower risk of VUR in children. Conclusion: Deletion of GSTT1 functional gene is a genetic risk factor causing VUR in children. Interestingly, the combination of GSTM1 and GSTP1 null genotypes with GSTT1 has shown a protective role against risk of GSTT1 deletion.

Abstract
Gastric cancer remains the third leading cause of mortality from cancer worldwide and carries a poor prognosis, due largely to late diagnosis. The importance of the interaction between Helicobacter pylori (H. pylori) infection, the main risk factor, and host-related genetic factors has been studied intensively in recent years. The genetic predisposition for non-hereditary gastric cancer is difficult to assess, as neither the real prevalence of premalignant gastric lesions in various populations nor the environmental risk factors for cancer progression are clearly defined. For non-cardiac intestinal-type cancer, identifying the factors that modulate the progression from inflammation toward cancer is crucial in order to develop preventive strategies. The role of cytokines and their gene variants has been questioned in regard to non-self-limiting H. pylori gastritis and its evolution to gastric atrophy and intestinal metaplasia; the literature now includes various and non-conclusive results on this topic. The influence of the majority of cytokine single nucleotide polymorphisms has been investigated for gastric cancer but not for preneoplastic gastric lesions. Among the investigated gene variants onlyIL10T-819C, IL-8-251, IL-18RAP917997, IL-22 rs1179251, IL1-B-511, IL1-B-3954, IL4R-398 and IL1RN were identified as predictors for premalignant gastric lesions risk. One of the most important limiting factors is the inhomogeneity of the studies (e.g., the lack of data on concomitant H. pylori infection, methods used to assess preneoplastic lesions, and source population). Testing the modifying effect of H. pylori infection upon the relationship between cytokine gene variants and premalignant gastric lesions, or even testing the interaction between H. pylori and cytokine gene variants in multivariable models adjusted for potential covariates, could increase generalizability of results.

Abstract
The incidence of thyroid cancer (TC), particularly well-differentiated forms (DTC), has been rising and remains the highest among endocrine malignancies. Although ionizing radiation (IR) is well established on DTC aetiology, other environmental and genetic factors may also be involved. DNA repair single nucleotide polymorphisms (SNPs) could be among the former, helping in explaining the high incidence. To further clarify the role of DNA repair SNPs in DTC susceptibility, we analyzed 36 SNPs in 27 DNA repair genes in a population of 106 DTCs and corresponding controls with the aim of interpreting joint data from previously studied isolated SNPs in DNA repair genes. Significant associations with DTC susceptibility were observed for XRCC3 rs861539, XPC rs2228001, CCNH rs2230641, MSH6 rs1042821 and ERCC5 rs2227869 and for a haplotype block on chromosome 5q. From 595 SNP-SNP combinations tested and 114 showing relevance, 15 significant SNP combinations (p < 0.01) were detected on paired SNP analysis, most of which involving CCNH rs2230641 and mismatch repair variants. Overall, a gene-dosage effect between the number of risk genotypes and DTC predisposition was observed. In spite of the volume of data presented, new studies are sought to provide an interpretability of the role of SNPs in DNA repair genes and their combinations in DTC susceptibility.

Abstract
Abstract
Objective: To evaluate the impact of congestive heart failure and the most important clinical and pathological factors on severe upper digestive mucosal lesions.
Methods: The study included 749 patients referred for upper digestive endoscopy, divided into two groups: 140 subjects with congestive heart failure (study group) and 609 subjects without heart failure (control group).
Results: Severe endoscopic lesions quantified according to Lanza score (OR = 3.84, 95% IC: 2.62-5.62), active/inactive gastritis (OR = 2.07, 95% CI: 1.36-3.14), intestinal metaplasia and/or gastric atrophy (OR = 2.42, 95% CI: 1.67-3.52) were significant more frequent among patients with heart failure. Anemia (OR = 3.65, 95% IC: 2.48-5.37) and all investigated comorbidities, as well as alcohol consumption (OR = 1.60, 95% IC: 1.10-2.34) and smoking (OR = 1.76, 95% IC: 1.17-2.64) were more frequent in the study-group. Dividing the patients with cardiac insufficiency according to the severity of their endoscopic lesions, the male gender (OR = 2.76, 95% IC: 1.35–5.61) and daily low-dose aspirin consumption were found to be more frequent among patients with severe endoscopic lesions (OR = 7.71, 95% IC: 3.62–16.40), while anticoagulant therapy and alcohol consumption were borderline associated with mucosal lesions (p=0.08).
Conclusions: Male patients and aspirin consumers with heart failure, but not those with H. pylori infection seem to be more prone to develop upper digestive endoscopic lesions, while alcohol consumption or anticoagulant therapy could be other modifiable factors associated with severe endoscopic lesions in a congestive gastro-duodenal mucosa.

Abstract
Abstract
Background: The additional benefits of certain frequently used chronic drugs such as statins or aspirin are investigated for their possible effect of influencing various types of cancer, including gastric cancer. The possible role of statins in the occurrence of pre-neoplastic gastric lesions has not been investigated.
Aim: The study aims to determine the influence of chronic statin therapy on premalignant gastric lesions (glandular atrophy, intestinal metaplasia and dysplasia), adjusted with the most important aggressive environmental factors of the gastric mucosa (Helicobacter pylori [H. pylori] infection, low-dose aspirin [acetylsalicylic acid, ASA], biliary reflux, smoking, alcohol consumption).
Method: The study included 566 patients with cardiovascular diseases who underwent an upper endoscopy: 222 patients with chronic statin therapy (atorvastatin 20–80 mg/day or rosuvastatin 5–20 mg/day for at least 6 months) and 344 patients without statin intake. A complete set of biopsies from the gastric antrum and corpus were routinely processed and examined, and demographical, clinical, and pathological variables were recorded.
Results: Active H. pylori infection in gastric biopsies (p = 0.45), biliary reflux (p = 0.74), alcohol consumption (p = 0.43), or prior ulcer disease (p = 0.07; OR: 0.59; 95% CI: 0.33–1.04) were not associated with an increased risk for premalignant lesions, neither in the statin, nor the no-statin group. Smoking was associated with premalignant lesions in both groups (p = 0.01; OR: 2.24; 95% CI: 1.12–4.47; and p = 0.04; OR: 1.72; 95% CI: 1.01–2.94, respectively), while chronic use of ASA had no influence (p = 0.24, respective p = 0.35). In multivariate regression models, chronic treatment with statins had a protective effect (p = 0.006; OR: 0.59; 95% CI: 0.4–0.8), while smoking (p = 0.01; OR: 1.99; 95% CI: 1.17–3.39) and age >50 years (p <0.01, OR: 3.09; 95% CI: 1.84–5.21) were predictors for pre-neoplastic lesions. H. pylori infection, gender, alcohol consumption, biliary reflux, or prior ulcer disease were not associated with premalignant lesions (p >0.05). Conclusions: In the studied population, chronic statin treatment seems to be associated with a decreased risk for premalignant gastric lesions, while age over 50 years and smoking, regardless of gender or ASA consumption, remain the most important risk factors for premalignant gastric lesions.

Abstract
Experimental studies showed a dose-dependent gastroprotective effect of statins on non-steroidal anti-inflammatory drug-induced endoscopic lesions, modulated by increasing endogenous nitric oxide and prostaglandin production.We investigated the influence of chronic treatment with statins on the occurrence of endoscopic lesions in patients referred for endoscopic evaluation, adjusted for the most important etiologic and risk factors for peptic ulcer disease and its complications.A consecutive series of 564 patients who underwent upper digestive endoscopy, stratified according to the severity of endoscopic lesions were recruited. Patients with statin therapy were included in the study group (n = 220), while patients without statins in the control group (n = 344). We correlate the influence of chronic statin therapy (at least 6 months) with factors including age up to 50 years, Helicobacter pylori infection, smoking and drinking habits, ulcer history, gastrotoxic drug consumption (low-dose aspirin [ASA], anticoagulants), and comorbidities.H pylori infection was more frequent in patients with mild/severe endoscopic lesions vs. no lesions, in both groups, but the difference was not statistically significant (P >.05). Male gender represented a risk factor (P <.01) for mild/severe endoscopic lesions only in the statin group. The estimated risk for developing mild/severe endoscopic lesions with ASA intake decreased from 6.26 to 3.40 (P <.01) when statin therapy was associated. Patients without statins and ischemic coronary artery disease (P <.01; odds ratio [OR] = 2.99; 95% confidence interval (CI):1.88-4.73), heart failure (P = .01; OR = 2.13; 95% CI:1.36-3.34), systemic atherosclerosis (P = .04; OR = 2.30; 95% CI:1.44-3.67) had a statistically significant increased risk for developing mild/severe endoscopic lesions in comparison with patients in the statin group. In multivariate regression analysis models, smoking (P <.01; OR = 2.69; 95% CI:1.73-4.16), ASA (P <.01; OR = 4.54; 95% CI:2.83-7.16), and coronary artery diseases (P = .01; OR = 1.80; 95% CI:1.15-2.82) were independent risk factors for mild/severe endoscopic lesions, while chronic statin therapy (P <.01; OR = 0.31; 95% CI:0.19-0.51) was associated with a protective effect in all models.The results of the present study support a certain protective role of chronic therapy with statins against endoscopic lesions, especially in ASA consumers or patients with cardiovascular diseases.

Factors Associated with Recurrent Ulcers in Patients with Gastric Surgery after More Than 15 Years: A Cross-Sectional Single-Center Study. Gastroenterol Res Pract 2018; 2018:8319481. [PMID: 30524477 PMCID: PMC6247467 DOI: 10.1155/2018/8319481] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2017] [Accepted: 04/19/2018] [Indexed: 12/14/2022] Open
Abstract
Aim We aimed to establish the independent predictive factors (from Helicobacter pylori infection, biliary reflux, histologic features of the gastric mucosa, drugs, comorbidities, and social habits) for gastric stump ulcer occurrence more than 15 years after surgery. Methods 76 patients with previous gastric surgery were included: 21 patients with gastric ulcer (marginal ulcer or ulcer of the rest of the gastric remnant-study group) and 55 controls (nonulcer group). Results Helicobacter pylori infection tended to be higher in the control group than in the ulcer group (14.5% vs. 4.8%, p = 0.43), without statistical significance. Alcohol consumption had a significant positive association with ulcer (p = 0.008), while smoking (p = 0.064), low-dose aspirin (p = 0.063), and biliary reflux (p = 0.106) had a tendency toward statistical signification for positive association. On univariate analysis, smoking (p = 0.048, OR = 3.15, 95% CI: 1.01-9.93) and low-dose aspirin consumption (p = 0.067, OR = 2.63, 95% CI: 0.95-7.68) were significantly associated with ulcer. According to the multivariable regression model, alcohol consumption (OR = 6.68, 95% CI: 1.29-41.14) and biliary reflux (OR = 6.12, 95% CI: 1.36-38.26) remained significantly associated with increased odds of stump ulcer. Conclusion Biliary reflux and alcohol consumption, but not Helicobacter pylori infection or gastrotoxic drug, seem to be the most important predictors for ulcer recurrence in patients with gastric surgery for peptic ulcer after more than 15 years.

World J Gastroenterol 2018; 24:602-612. [PMID: 29434449 PMCID: PMC5799861 DOI: 10.3748/wjg.v24.i5.602] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2017] [Revised: 12/05/2017] [Accepted: 12/12/2017] [Indexed: 02/06/2023] Open
Abstract
AIM To investigate the interactions of the DNA repair gene excision repair cross complementing group 5 (ERCC5) and the metabolic gene glutathione S-transferase pi 1 (GSTP1) and their effects on atrophic gastritis (AG) and gastric cancer (GC) risk.
METHODS Seven ERCC5 single nucleotide polymorphisms (SNPs) (rs1047768, rs2094258, rs2228959, rs4150291, rs4150383, rs751402, and rs873601) and GSTP1 SNP rs1695 were detected using the Sequenom MassARRAY platform in 450 GC patients, 634 AG cases, and 621 healthy control subjects in a Chinese population.
RESULTS Two pairwise combinations (ERCC5 rs2094258 and rs873601 with GSTP1 rs1695) influenced AG risk (Pinteraction = 0.008 and 0.043, respectively), and the ERCC5 rs2094258-GSTP1 rs1695 SNP pair demonstrated an antagonistic effect, while ERCC5 rs873601-GSTP1 rs1695 showed a synergistic effect on AG risk OR = 0.51 and 1.79, respectively). No pairwise combinations were observed in relation to GC risk. There were no cumulative effects among the pairwise interactions (ERCC5 rs2094258 and rs873601 with GSTP1 rs1695) on AG susceptibility (Ptrend > 0.05). When the modification effect of Helicobacter pylori (H. pylori) infection was evaluated, the cumulative effect of one of the aforementioned pairwise interactions (ERCC5 rs873601-GSTP1 rs1695) was associated with an increased AG risk in the case of negative H. pylori status (Ptrend = 0.043).
CONCLUSION There is a multifarious interaction between the DNA repair gene ERCC5 SNPs (rs2094258 and rs873601) and the metabolic gene GSTP1 rs1695, which may form the basis for various inter-individual susceptibilities to AG.

INTERNATIONAL JOURNAL OF CLINICAL AND EXPERIMENTAL PATHOLOGY 2017; 10:9945-9950.

Abstract
This study was undertaken to detect the incidence of variations in exon 5 of GSTP1, a member of the glutathione-S-transferase family, in gastric cancer in relation to histological parameters. The study included 216 gastric cancers and 300 benign gastric diseases as controls. DNA was extracted from paraffin-embedded tissues and polymerase chain reaction-restriction fragment length polymorphism analysis was performed to examine the GSTP1 Ile105Val gene polymorphism in the study participants. A positive association between GSTP1 polymorphism and gastric cancer was observed in subjects carrying at least one G allele (AG and GG); the adjusted odds ratio (OR) for GSTP1 AA versus AG+GG was 1.416 (95% confidence interval [CI] 1.007 to 1.989, after controlling for age and gender). Patients over 50 years old more frequently carried the AG+GG genotype than those aged less than 50 (P=0.011) with adjusted OR (95% CI) of 2.758 (1.227-6.201). Compared with the well-differentiated group, the incidence of the GSTP1 AA genotype was decreased in the moderately [P=0.026; OR (95% CI)=3.559 (1.072-11.813)] and poorly [P=0.003; OR (95% CI)=6.015 (1.679-21.549)] differentiated groups. The incidence of the GSTP1 AA genotype in intestinal type was higher than that in diffuse type (adjusted P=0.014; OR [95% CI]=2.210 [1.160-4.210]). All results indicated that the GSTP1 Ile105Val variant was closely associated with an increased risk of gastric cancer, and was significantly associated with patient age, tissue differentiation degree, and Lauren classification but not with gender, gross classification, tumor size (diameter), infiltration depth, and lymph node involvement.
