The Analysis of NADPH Quinone Reductase 1 (NQO1) Polymorphism in Polish Patients with Colorectal Cancer. Biomolecules 2021; 11:biom11071024. [PMID: 34356648 PMCID: PMC8301863 DOI: 10.3390/biom11071024] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2021] [Revised: 07/05/2021] [Accepted: 07/11/2021] [Indexed: 12/24/2022] Open
Abstract
Colorectal cancer (CRC) is one of the most common malignancies in Poland. Based on the findings of clinical trials, it is safe to conclude that genetic predisposition and environmental factors are the main factors responsible for the formation of colorectal cancer.The NQO1 gene plays an important role in reducing endogenous and exogenous quinones as well as quinone compounds to hydroquinones. It is an enzyme which is a part of the body’s antioxidant defense system. The aim of the study was to evaluate the correlation between the 609C > T polymorphism of the NQO1 gene and colorectal cancer risk in the Polish population. A total of 512 people were recruited for the study, including 279 patients with colorectal cancer, diagnosed at the University Hospital, Pomeranian Medical University in Szczecin. Genomic DNA was isolated from peripheral blood and the analyzed polymorphism was determined by PCR-RFLP. In the present study, we analyzed the clinical valuesand frequency of NQO1 609C > T polymorphism in patients diagnosed with colorectal cancer and controls. In case of the carriers of the TT genotype of the NQO1 polymorphism, an elevated risk for colorectal cancer was observed (OR = 2.96; 95% CI: 1.02–10.40). The analysis of the clinical parameters concerning the location and characteristics of the tumor stage revealed a statistically significant increase in the risk for colorectal cancer in the carriers of the TT genotype of the NQO1 polymorphism.

Abstract
NQO1, NAD(P)H: quinone oxidoreductase 1, was first identified in rat and its role has been extensively studied. Even the roles of NQO1 in the maintenance of physiological function and disease were largely addressed, whether the tissue specific functions of the NQO1 in organ development remains unknown. In the current study, we identified two NQO1 isoforms (isoform 1 and isoform 2) and examined the expression of nqo1 variants in adult zebrafish organs and embryos at different stages. In adult organs, RT-PCR result indicated that nqo1 variant 1 was mainly expressed in stomach and intestine, while nqo1 variant 2 was expressed in all organs investigated except for heart. Further, RT-PCR result showed that the nqo1 variant 1 and variant 2 were expressed at all the embryonic stages, but nqo1 variant 1 expression level was much lower than that of nqo1 variant 2. To specifically examine the expression pattern of these two different nqo1 variants, we did whole mount in situ hybridization and the results demonstrated that, both of them were maternally expressed at 8-cell stage, and they were all expressed ubiquitously at early stage. At 24 hpf, nqo1 variant 2 was mainly expressed in yolk cells, and slightly in head and eyes. At 48 hpf, nqo1 variant 2 was restricted in lateral line neuromasts. From 72 hpf to 144 hpf, nqo1 variant 2 was mainly restricted in branchial arch, liver, swimming bladder and lateral line neuromasts, while from 124 hpf to 192 hpf, nqo1 variant 2 only restricted in liver, and disappeared in lateral line neuromasts. On the contrary, at the late embryonic stage, nqo1 variant 1 was only expressed in liver and swimming bladder while not in branchial arch and lateral line neuromasts. In conclusion, we systematically analyzed the expression pattern of nqo1 variant 1 and variant 2 in zebrafish at different embryonic stages, and our data implied the possible role of nqo1 in regulating liver, branchial arch and lateral neuromasts development.

Abstract
ABSTRACT BACKGROUND: Gastric cancer is the fourth most common cause of worldwide cancer. Also in contrast to the huge advances in curing, the chance of living is very low even in surgery cases. Having a genetic predisposition plays an important role in cancer development. The association between Metallothionein-2A gene polymorphisms and the risk of adenocarcinoma has been widely studied, yet there is only one study on stomach diseases. OBJECTIVE: In this study, we aimed to investigate the association between 2 (MT-2A) polymorphisms and adenocarcinoma. METHODS: This cross-sectional case control study was performed between Mach 2014 and January 2015 at the Tuba Hospital of Sari, Iran. Peripheral blood samples were collected in EDTA tube. DNA extraction was performed using the spin column procedure. The MT-2A polymorphisms MT-2A (rs1610216), (rs28366003) were determined by polymerase chain reaction-restriction fragment length polymorphism analysis in 95 a topic adenocarcinoma patients and 90 healthy individuals from Iranian population. RESULTS: The MT-2A rs1610216 polymorphism increased the risk of adeno carcinoma in our Iranian population [OR: 3.8533; 95%CI, 1.3155-11.2869; P=0.0139] and rs28366003 [OR: 4.0978; 95%CI, 1.2521-13.4108; P=0.0197]. CONCLUSION: The MT-2A gene polymorphism was associated with the risk of adenocarcinoma in the Iranian population.

Abstract
To explore the role of NQO1 overexpression for prognostic implication in hepatocellular carcinoma (HCC), NQO1 mRNA levels were detected in HCC fresh tissue samples of HCC and nontumor tissues, respectively. One hundred fifty-six cases of HCC meeting strict follow-up criteria were selected for immunohistochemical staining of NQO1 protein. Correlations between NQO1 overexpression and clinicopathological features of HCC were evaluated using χ2 tests, survival rates were calculated using the Kaplan-Meier method, and the relationship between prognostic factors and patient 5-year survival was analyzed using Cox proportional hazards analysis. In results, the levels of NQO1 mRNA were significantly up-regulated in 14 fresh tissue samples of HCC. Immunohistochemical analysis showed that the NQO1 expression and overexpression rates were significantly higher in HCC samples compared with either adjacent nontumor tissues or normal liver tissues. NQO1 overexpression correlated to tumor size, venous infiltration and late pTNM stage of HCC. NQO1 overexpression was also related to low disease-free survival and 5-year survival rates. In the late-stage group, disease-free and 5-year survival rates of patients with NQO1 overexpression were significantly lower than those of patients without NQO1 expression. Further analysis using a Cox proportional hazards regression model revealed that NQO1 expression emerged as a significant independent hazard factor for the 5-year survival rate of patients with HCC. Therefore, NQO1 plays an important role in the progression of HCC. NQO1 may potentially be used as an independent biomarker for prognostic evaluation of HCC.

Abstract
INTRODUCTION A FEW STUDIES HAVE REPORTED AN ASSOCIATION BETWEEN NADP(H): quinine oxidoreductase 1 (NQO1) C609T polymorphism and susceptibility to colorectal cancer (CRC). However, the results were inconsistent rather than conclusive. We performed a meta-analysis to examine this association in various populations. MATERIAL AND METHODS Eligible articles were identified by a search of several databases up until June 30, 2013. Summary odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the strength of the association. RESULTS Overall, 14 case-control studies with 4,461 cases and 5,474 controls were included in this meta-analysis. The results indicated that the NQO1 C609T polymorphism was significantly associated with CRC susceptibility (summary ORs (95% CIs): 1.30 (1.07-1.59) for CT vs. CC, 1.64 (1.15-2.33) for TT vs. CC, 1.34 (1.10-1.64) for TT/CT vs. CC, and 1.43 (1.10-1.87) for TT vs. CT/CC). Subgroup analyses indicated that the T allele was significantly associated with CRC susceptibility in both Asians and Caucasians, and was also observed in high quality studies and hospital-based case-control studies. Specifically, we found a positive association between the NQO1 C609T polymorphism and CRC susceptibility in smokers, but not in non-smokers. CONCLUSIONS The results of this meta-analysis suggest that the NQO1 C609T polymorphism significantly contributes to increased susceptibility to CRC in both Asians and Caucasians.

Abstract
NQO1 (NAD(P)H: quinone oxidoreductase, also known as DT-diaphorase) plays a prominent role in maintaining cellular homeostasis. NQO1 is abnormally elevated in many solid cancer types, including those of the adrenal gland, breast, colon, lung, ovary, and thyroid. However, little is known about the status of NQO1 in gastric adenocarcinoma (GAC). To investigate the clinicopathological significance of NQO1 expression in GAC, and thus evaluate its role as a potential prognostic marker, 203 cases of primary GAC, 31 of gastric dysplasia, and 53 of adjacent non-tumor tissues were selected for immunohistochemical staining of NQO1 protein. Correlations between NQO1 overexpression and clinicopathological characteristics were evaluated by χ(2) test and Fisher's exact test, while survival rates were calculated by Kaplan-Meier method. The relationship between prognostic factors and patient survival was analyzed by Cox proportional hazards model. Through these analyses it was found that the strongly positive rate of NQO1 protein in GAC was significantly higher than that in gastric dysplasia and adjacent non-tumor tissues. Analysis by qRT-PCR also confirmed that NQO1 mRNA levels were increased in GAC compared with those detected in either adjacent non-tumor tissues or normal gastric mucosa. Additionally, the NQO1 expression rate was positively correlated with tumor size, serosal invasion, tumor stage, and both disease-free survival and 5-year survival rates. Further analysis showed that although NQO1 was not an independent predictor of GAC, elevated expression of NQO1 could predict lower disease-free survival and 5-year survival times in late-stage patients. In conclusion, NQO1 plays an important role in the progression of GAC, and might be a potential, but not an independent, poor prognostic biomarker and therapeutic target of GAC.

Abstract
NAD(P)H quinone oxidoreductase (NQO1) and NRH:quinone oxidoreductase 2 (NQO2) catalyze the two-electron reduction of quinones and thereby prevent generation of toxic radicals. Quinone methides (QMs) covalently react with cellular macromolecules to form DNA adducts and/or protein conjugates resulting in toxicity and carcinogenesis. Based on similar structural features of quinones and QMs, it is logical to assume that NQO1 and/or NQO2 could also catalyze the two-electron reduction of QMs. However, hitherto the reduction of QMs, as both endogenous and/or exogenous biological substrates, by either NQO1/NQO2 has never been demonstrated. Here we show for the first time that both NQO1 and NQO2 can catalyze the reduction of electrophilic ortho-/para-QMs. The involvement of the enzyme in the reduction of p-cresol quinone methide (PCQM) and o-cresol quinone methide (OCQM) was demonstrated by reappearance of NQO1/NQO2-FAD peak at 450 nm after addition of the QMs to the assay mixture. Further reduction of methides by NQO1/NQO2 was confirmed by analyzing the assay mixture by tandem mass spectrometry. Preliminary kinetic studies show that NQO2 is faster in reducing QMs than its homolog NQO1, and moreover, ortho-QMs are reduced faster than para-QMs. Enzyme-substrate docking studies showed results consistent with enzyme catalysis. Thus, NQO1/NQO2 can play a significant role in deactivation of QMs.

Abstract
Gastric cancer is a lethal disease with a high mortality rate. Studies have suggested that prostate stem cell antigen (PSCA) rs2294008 polymorphism is associated with gastric cancer (GC). In this case-control study, we investigated rs2294008 polymorphism in the Tibet, Hui and Han nationalities in the Qinghai area of China. Genomic DNA was extracted from the peripheral blood of 286, 315 and 350 healthy volunteers and from 219, 233 and 265 Helicobacter pylori-negative non-cardia GC patients from the Tibet, Hui and Han populations, respectively. The rs2294008 polymorphism was analyzed by denaturing high-performance liquid chromatography. rs2294008 CT and TT genotypes were associated with GC both in the Tibet and Han populations (adjusted OR=1.51, 1.47, 2.01, 1.85; 95% CI, 1.04-2.19, 1.05-2.06, 1.04-3.88, 1.03-3.34; P=0.030, 0.025, 0.039, 0.040, respectively). rs2294008 TT genotype was associated with GC in the Hui population (adjusted OR=2.14; 95% CI, 1.29-3.55; P=0.003). Furthermore, when stratified by histopathology, the rs2294008 CT and TT genotypes were associated with diffuse GC in the Tibet and Han nationalities (adjusted OR=1.93, 1.73, 2.69, 2.86; 95% CI, 1.09-3.44, 1.01-2.95, 1.06-6.84, 1.27-6.46; P=0.025, 0.045, 0.038, 0.011, respectively). However, the rs2294008 TT genotype was associated with both intestinal and diffuse types of GC (adjusted OR=2.10, 2.21; 95% CI, 1.17-3.75, 1.12-4.38; P=0.012, 0.023, respectively) and the rs2294008 CT genotype was only associated with intestinal-type GC in the Hui nationalitiy group (adjusted OR=1.60; 95% CI, 1.04-2.47; P=0.034). The results therefore showed that rs2294008 may differentially contribute to GC among different nationalities in one area and its role is independent from Helicobacter pylori-infection.
