Abstract
Abstract
Background
The etiology of bladder cancer is not yet well known. In this study, we want to evaluate the effect of polymorphisms of genes that have an epigenetic effect (MTHFR, DNMT3A/B) on the susceptibility to develop bladder cancer (BC).
Methods
A systematic review was performed for MTHFR, DNMT3A, and DNMT3B, followed by a meta-analysis conducted for rs1801131, rs1801133, rs2274976, rs1550117, and rs1569686 SNPs. A sensitivity and a subgroup analysis were then used.
Results
20 studies were included, where no statistically significant association between any of the analyzed SNPs and the occurrence of BC was detected. Subgroup analysis revealed a statistically significant association in North African population with rs1801133: TT vs. TC + CC (P = 0.013; OR 95% CI = 0.52 [0.311–0.872]); TT vs.TC (P = 0.003; OR 95% CI = 0.448 [0.261–0.769]) and in North American population with rs1801131: CC vs. CA (P = 0.039; OR 95% CI = 0.71 [0.523–0.984]). A sensitivity analysis revealed that there is a statistically significant association between rs1801131 and the occurrence of BC (OR = 0.79, 95%CI [0.65–0.97]), (OR = 0.80, 95%CI [0.65–0.98]) and (OR = 0.78, 95%CI [0.63–0.96]) which correspond to CC vs. CA + AA; CC vs. CA; and CC vs. AA genetic models.
Conclusion
This is the first study to assess the effect of DNMTs on bladder cancer risk. No statistically significant association was found between polymorphisms of MTHFR, DNMT3A/B genes and bladder cancer development, except for the North African and the North American populations with rs1801133 and rs1801131, respectively, with a protective effect of rs1801131 based on a sensitivity analysis.

Hernández-González O, Herrera-Vargas DJ, Martínez-Leija ME, Zavala-Reyes D, Portales-Pérez DP. The role of arylamine N-acetyltransferases in chronic degenerative diseases: Their possible function in the immune system. BIOCHIMICA ET BIOPHYSICA ACTA. MOLECULAR CELL RESEARCH 2022; 1869:119297. [PMID: 35588943 DOI: 10.1016/j.bbamcr.2022.119297] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Revised: 05/11/2022] [Accepted: 05/12/2022] [Indexed: 06/15/2023]
Abstract
Since their discovery, arylamine N-acetyltransferases 1 and 2 (NAT1 and NAT2, respectively) have been associated with the metabolism of xenobiotics. NAT2 is the main factor in the therapeutic success of tuberculosis treatment due to its role in the biotransformation of isoniazid. However, researchers have started to investigate the possible participation of NAT1 and NAT2 (NATs) in carcinogenesis, although the mechanisms have not been elucidated fully. NATs enzymatic activity is essential in some types of cancer, such as breast cancer and acute lymphoblastic leukemia. Whether NAT1 and/or NAT2 participate in insulin resistance level in diabetes mellitus or in the immune system remains to be explored. Therefore, it is clear that its role in cell physiology has more implications than just metabolizing compounds.

Investigation of the relationship between MTRR A66G, MTR A2756G gene variations and cell anomalies in early diagnosis and progression of bladder cancer. Mol Biol Rep 2022; 49:7719-7729. [PMID: 35715601 DOI: 10.1007/s11033-022-07597-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Revised: 05/08/2022] [Accepted: 05/11/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND The aim of this study is to investigate the relationship between MTRR A66G, MTRA2756G gene variations and cell anomalies in the early diagnosis and progression of bladder cancer. METHODS PCR and RFLP methods were used to determine the genotype distributions of MTRR A66G and MTR A2756G gene variations. Peripheral smear preparations prepared from blood samples were fixed with methanol fixative and stained histochemically. Cellular morphological evaluations were made under the light microscope. RESULTS In our study, AA-GG haplotype was observed significantly more in the patient group than control group (OR: 3.304, 95% CI: 1.023-10.665, p = 0.046). The significant increase was determined in terms of histological damage parameters in the patient group compared to the control group (p < 0.05). For multiple vacuoles damage parameter (mild score), AA genotype of MTR A2756G gene variation was significantly different compared to AA genotype of MTRR A66G gene variation (OR: 0.211, 0.049-0.912, p = 0.037). AA genotype of MTR A2756G gene variation was observed more than AA homozygous genotype of MTR A66G gene variation for giant platelets with different sizes damage parameter (mild score) (OR: 0.062, 0.017-0.228, p < 0.001). CONCLUSIONS In conclusion, in Thrace population, AA genotype of the MTR A2756G gene variation was significantly higher than the AA homozygous genotype of the MTR A66G gene variation as a genetic risk factor for the multiple vacuoles damage parameter. In addition, AA genotype of MTR A2756G gene variation was determined as a genetic risk factor for giant platelets with different sizes damage parameter.

Maternal Haplotypes in DHFR Promoter and MTHFR Gene in Tuning Childhood Acute Lymphoblastic Leukemia Onset-Latency: Genetic/Epigenetic Mother/Child Dyad Study (GEMCDS).

Abstract
Childhood acute lymphoblastic leukemia (ALL) peaks around age 2–4, and in utero genetic epigenetic mother-fetus crosstalk might tune ALL onset during childhood life. Folate genes variably interact with vitamin status on ALL risk and prognosis. We investigated DHFR and MTHFR gene variants in 235 ALL children and their mothers to disclose their role in determining ALL onset age and survival. Pyrosequence of DHFR 19bp ins/del (rs70991108; W/D), MTHFR C677T (rs1801133; C>T), and MTHFR A1298C (rs1801131; A>C) was assessed in children and in 72% of mothers for dyad-analysis comparison. DHFR DD-children had delayed ALL onset compared to WW-children (7.5 ± 4.8 vs. 5.2 ± 3.7 years; P = 0.002) as well as MTHFR 1298 CC-children compared to AA-children (8.03 ± 4.8 vs. 5.78 ± 4.1 years; P = 0.006), and according to the strong linkage disequilibrium between MTHFR 677 T-allele and 1298C-allele, MTHFR TT-children showed early mean age of onset though not significant. Offspring of MTHFR 677 TT-mothers had earlier ALL onset compared to offspring of 677 CC-mothers (5.4 ± 3.3 vs. 7 ± 5.3 years; P = 0.017). DHFR/MTHFR 677 polymorphism combination influenced onset age by comparing DD/CC vs. WW/TT children (8.1 ± 5.7 vs. 4.7 ± 2.1 years; P = 0.017). Moreover, mother-child genotype combination gave 5.5-years delayed onset age in favor of DD-offspring of 677 CC-mothers vs. WW-offspring of 677 TT-mothers, and it was further confirmed including any D-carrier children and any 677 T-carrier mothers (P = 0.00052). Correction for multiple comparisons maintained statistical significance for DHFR ins/del and MTHFR A1298C polymorphisms. Unexpectedly, among the very-early onset group (<2.89 years; 25th), DD-genotype inversely clustered in children and mothers (4.8% vs. 23.8% respectively), and accordingly ALL offspring of homozygous DD-mothers had increased risk to have early-onset (adjusted OR (odds ratio) = 3.08; 1.1–8.6; P = 0.03). The opposite effect DHFR promoter variant has in tuning ALL onset-time depending on who is the carrier (i.e., mother or child) might suggest a parent-origin-effect of the D-allele or a two-faced epigenetic role driven by unbalanced folate isoform availability during the in-utero leukemogenesis responsible for the wide postnatal childhood ALL latency.

Abstract
BACKGROUND N-acetyl-transferase 2 (NAT2) polymorphisms have been demonstrated to be associated with acute leukemia (AL); however, the results remain controversial. The present meta-analysis was performed to provide more precise results. METHODS Pubmed, Embase, Cochrane Library, China National Knowledge Infrastructure, and Wanfang databases were used to identify eligible studies. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to evaluate the strength of the association between NAT2 polymorphisms and AL risk. RESULTS Increased risk was found under both heterozygous (OR 1.24, 95% CI 1.02-1.51) and recessive model (OR 1.28, 95% CI 1.06-1.55) for rs1801280. The slow acetylator phenotype (OR 1.22, 95% CI 1.07-1.40) also increased AL risk. Subgroup analysis demonstrated that rs1801280 increased AL risk under the recessive model (OR 1.14, 95% CI 0.93-1.41) in Caucasian population and the co-dominant (OR 1.77, 95% CI 1.40-2.23), homozygous (OR 3.06, 95% CI 1.88-4.99), dominant (OR 2.22, 95% CI 1.56-3.17), recessive model (OR 2.06, 95% CI 1.35-3.16) in the Mixed populations. Association between rs1799929 and decreased AL risk was found in the co-dominant (OR 0.82, 95% CI 0.70-0.97), homozygous (OR 0.65, 95% CI 0.46-0.93), heterozygous (OR 0.71, 95% CI 0.51-1.00), and the recessive model (OR 0.68, 95% CI 0.49-0.94) in the Caucasian group. As for rs1799931, the same effects were found in the co-dominant (OR 0.68, 95% CI 0.49-0.94) and the dominant model (OR 0.68, 95% CI 0.48-0.97) in the mixed group. CONCLUSION rs1801280 and the slow acetylator phenotype are risk factors for AL.

Impact of methylenetetrahydrofolate reductase C677T polymorphism on the efficacy of photodynamic therapy in patients with neovascular age-related macular degeneration. Sci Rep 2019; 9:2614. [PMID: 30796269 PMCID: PMC6385217 DOI: 10.1038/s41598-019-38919-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2018] [Accepted: 01/02/2019] [Indexed: 02/07/2023] Open
Abstract
The most severe visual impairments due to age-related macular degeneration (AMD) are frequently caused by the occurrence of choroidal neovascularization (CNV). Although photodynamic therapy with verteporfin (PDT-V) is currently a second-line treatment for neovascular AMD, it can be conveniently combined with drugs acting against vascular endothelial growth factor (anti-VEGF) to reduce the healthcare burden associated with the growing necessity of anti-VEGF intravitreal re-injection. Because the common 677 C > T polymorphism of the methylenetetrahydrofolate reductase gene (MTHFR-C677T; rs1801133) has been described as predictor of satisfactory short-term responsiveness of AMD-related CNV to PDT-V, we retrospectively examined the outcomes of 371 Caucasian patients treated with standardized, pro-re-nata, photodynamic regimen for 24 months. Responder (R) and non-responder (NR) patients were distinguished on the basis of the total number of scheduled PDT-V (TN-PDT-V) and change of best-corrected visual acuity (∆-BCVA). The risk for both TN-PDT-V and ∆-BCVA to pass from R to NR group was strongly correlated with CT and TT genotypes of MTHFR-C677T variant resulting, respectively, in odd ratios of 0.19 [95% CI, 0.12-0.32] and 0.09 [95% CI, 0.04-0.21] (P < 0.001), and odd ratios of 0.24 [95% CI, 0.15-0.39] and 0.03 [95% CI, 0.01-0.11] (P < 0.001). These pharmacogenetic findings indicate a rational basis to optimize the future clinical application of PDT-V during the combined treatments of AMD-related CNV, highlighting the role of thrombophilia to be aware of the efficacy profile of photodynamic therapy.

Abstract
Plenty of studies have investigated the effect of methionine synthase (MTR) A2756G polymorphism on risk of developing pediatric acute lymphoblastic leukemia (ALL), but the available results were inconsistent. Therefore, a meta-analysis was conducted to derive a more precise estimation of the association between MTR A2756G polymorphism and genetic susceptibility to pediatric ALL. The PubMed, Embase, Google Scholar, Web of Science, ScienceDirect, Wanfang Databases and China National Knowledge Infrastructure were systematically searched to identify all the previous published studies exploring the relationship between MTR A2756G polymorphism and pediatric ALL risk. Odds ratios (ORs) and 95% confidence intervals (CIs) were applied to evaluate the strength of association. Sensitivity analysis and publication bias were also systematically assessed. This meta-analysis finally included ten available studies with 3224 ALL cases and 4077 matched controls. The results showed that there was significant association between MTR A2756G polymorphism and risk of pediatric ALL in overall population (AG vs. AA: OR = 1.13, 95%CI = 1.02-1.26, P = 0.02; AG+GG vs. AA: OR = 1.13, 95%CI = 1.02-1.25, P = 0.01; G allele vs. A allele: OR = 1.10, 95%CI = 1.01-1.20, P = 0.03). In the stratification analyses by ethnicity, quality score and control source, significant association was found in Caucasians, population-based designed studies and studies assigned as high quality. In conclusion, this meta-analysis suggests that MTR A2756G polymorphism may influence the development risk of pediatric ALL in Caucasians. Future large scale and well-designed studies are required to validate our findings.

Abstract
BACKGROUND Numerous studies have focused on the association of methionine synthase (MS) A2756G polymorphism and acute hematological cancer risk. However, the results remain inconsistent. Therefore, a meta-analysis was performed to derive a more precise estimate of the association between them. METHODS This meta-analysis involved 25 articles (26 studies) including 8641 hematological cancer patients and 15,498 controls. The pooled odds ratios (ORs) and their corresponding 95% confidence intervals (CIs) of the association between MS A2756G polymorphism and the risk of hematological cancer were calculated. RESULTS Overall, no significant increased risks were found between MS A2756G polymorphism and hematological cancer risk under allelic homozygote (GA vs AA: OR = 0.98, 95% CI = 0.89-1.07, P = .62), heterozygote (GG vs AA: OR = 0.99, 95% CI = 0.85-1.15, P = .91), dominant (AG+GG vs AA: OR = 0.99, 95% CI = 0.90-1.08, P = .93), and recessive (GG vs AG+AA: OR = 1.00, 95% CI = 0.86-1.16, P = .97) models, respectively. In the stratified analyses by ethnicity and source of controls, there were still no significant associations between them in all genetic models. CONCLUSIONS Therefore, these findings demonstrate that MS A2756G polymorphism may not be a risk factor for hematological cancer.

Abstract
BACKGROUND Folic acid and its derivates, known as folates, are chemoprotective micronutrients of great interest because of their essential role in the maintenance of health and genomic integrity. The supplementation of folic acid during pregnancy has long been known to reduce the risk of neural tube defects (NTDs) in the foetus. Folate metabolism can be altered by many factors, including adequate intake through diet. Folate deficiency can compromise the synthesis, repair and methylation of DNA, with deleterious consequences on genomic stability and gene expression. These processes are known to be altered in chronic diseases, including cancer and cardiovascular diseases. MAIN BODY This review focuses on the association between folate intake and the risk of childhood leukaemia. Having compiled and analysed studies from the literature, we show the documented effects of folates on the genome and their role in cancer prevention and progression with particular emphasis on DNA methylation modifications. These changes are of crucial importance during pregnancy, as maternal diet has a profound impact on the metabolic and physiological functions of the foetus and the susceptibility to disease in later life. Folate deficiency is capable of modifying the methylation status of certain genes at birth in both animals and humans, with potential pathogenic and tumorigenic effects on the progeny. Pre-existing genetic polymorphisms can modify the metabolic network of folates and influence the risk of cancer, including childhood leukaemias. The protective effects of folic acid might be dose dependent, as excessive folic acid could have the adverse effect of nourishing certain types of tumours. CONCLUSION Overall, maternal folic acid supplementation before and during pregnancy seems to confer protection against the risk of childhood leukaemia in the offspring. The optimal folic acid requirements and supplementation doses need to be established, especially in conjunction with other vitamins in order to determine the most successful combinations of nutrients to maintain genomic health and wellbeing. Further research is therefore needed to uncover the role of maternal diet as a whole, as it represents a main factor capable of inducing permanent changes in the foetus.

Abstract
Cancer cells have epigenetic alterations that are known to drive cancer progression. The reversibility of the epigenetic posttranslational modifications on chromatin and DNA renders targeting these modifications an attractive means for cancer therapy. Cellular epigenetic status interacts with cell metabolism, and we are now beginning to understand the nature of how this interaction occurs and the biological contexts that mediate its function. Given the tremendous interest in understanding and targeting metabolic reprogramming in cancer, this nexus also provides opportunities for exploring the liabilities of cancers. This review summarizes recent developments in our understanding of the interaction of cancer metabolism and epigenetics.

Abstract
OBJECT Functionally relevant polymorphisms of methionine and folate metabolism have been shown to be associated with various human cancer entities including cerebral lymphoma and glioblastoma multiforme. The authors investigated the association of 7 functional polymorphisms of methionine metabolism with meningioma formation. METHODS This case-controlled, monocenter association study included 290 patients of Caucasian origin undergoing surgical resection for intracranial meningioma (World Health Organization [WHO] Grade I, 190 cases; WHO Grade II, 82 cases; WHO Grade III, 18 cases) and 287 age- and sex-matched local controls. The authors analyzed the following genetic variants: dihydrofolate reductase c.594+59del19, 5,10-methylenetetrahydrofolate reductase c.677C > T and c.1298A > C, 5-methyltetrahydrofolate-homocysteine S-methyltransferase (MTR) c.2756A > G, reduced folate carrier 1 c.80G > A, cystathionine beta-synthase (CBS) c.844_855ins68 and transcobalamin 2 c.776C > G. RESULTS The variant CBS c.844_855ins68 -- that is, the allele carrying the insertion ("ins" or "i") as opposed to the wild-type allele designated as deletion ("del" or "d") -- was significantly overrepresented in meningioma patients (dd/ id/ii: 0.81/0.18/0.01) in comparison with the controls (dd/id/ii: 0.88/0.12/0; 2 df, chi-square 8.97, p = 0.011; multiple nominal regression with age and sex as covariables). In addition, explorative analyses revealed an association of the MTR c.2756A > G variant with meningioma WHO Grade III (AA/AG/GG: patients, 1.0/0/0; controls, 0.64/0.32/0.04; 2 df, chi-square 14.44, p = 0.001). CONCLUSIONS The results of this study suggest that genetic variants of methionine metabolism are associated with meningioma formation.

Abstract
The cytogenetic effects of cigarette smoke has been evaluated as one of many potential confounders in a large number of biomonitoring studies of occupationally or environmentally exposed populations and control subjects. Despite the well-known presence of carcinogens in the cigarette smoke, the results in the scientific literature linking smoking habits to micronuclei (MN) frequency, one of the cytogenetic markers, are rather controversial. Here, we investigated the relationships among MN frequency, smoking habits and five folate metabolic enzyme gene polymorphisms (MTHFR C677T and A1298C, MTR A2756G, MTRR A66G and TYMS 3'UTR) in 132 healthy Japanese men who were non-habitual drinkers. In never- and former-smokers, no statistically significant differences in the mean MN frequencies were observed according to the five folate metabolic enzyme gene polymorphisms. In current-smokers, however, subjects with the AA genotype for MTRR had a significantly higher mean MN frequency than the AG genotypes for MTRR (p<0.05). Furthermore, among subjects with the AA genotype for MTRR, current-smokers were found to have a significantly higher mean MN frequency than never- and former-smokers (p<0.05). To further characterize this association, we stratified the smoking status into five groups: non-smokers (never-smokers and former-smokers), 1-10 cigarettes/day, 11-20 cigarettes/day, 21-30 cigarettes/day and >or=31 cigarettes/day. There was an overall trend for the mean MN frequency in subjects with the MTRR AA genotype to increase as the number of cigarettes smoked per day increased (p<0.01, Jonckheere-Terpstra test). The results of our preliminary study suggest that the MTRR AA genotype acts to increase the MN frequency resulting from cigarette smoking. Therefore, studies on human genotoxicity based on cytogenetic markers of MN should take into account both the MTRR polymorphism and the potential confounding effect of smoking, although these preliminary findings need to be validated in larger populations because of the relatively small sample size.

Abstract
Methionine metabolism provides two key cellular reagents: S-adenosylmethionine and glutathione, derived from the common intermediate, homocysteine. A majority of cancer cells exhibit a methionine-dependent phenotype whereby they are unable to grow in medium in which methionine is replaced by its precursor, homocysteine. Additionally, CpG island hypermethylation of tumor suppressor gene promoters is observed in a background of global hypomethylation in cancerous cells. In this study, we have profiled the expression levels of the homocysteine junction enzymes, methionine synthase (MS), MS reductase (MSR), and cystathionine beta-synthase (CBS) in the NCI60 panel of cancer cell lines. The doubling time of non-small lung cell cancer lines, which exhibit the lowest levels of MS within the panel, was significantly correlated with expression of MS. The ratio of MS to MSR varied over a 5-fold range in the different cell types, which may modulate methionine synthesis. Interestingly, markedly reduced CBS expression was seen in the methionine-dependent prostate cancer cell line, PC-3, but not in the methionine-independent cell line, DU-145. However, neither provision of the transsulfuration pathway product, cysteine, nor overexpression of CBS rescued the growth impairment, indicating that reduced CBS was not responsible for the methionine-dependent phenotype in this cell line.

Abstract
The methylenetetrahydrofolate reductase (MTHFR) 677C-->T polymorphism is thought to influence the partitioning of 1-carbon units between methylation and other components of 1-carbon metabolism and to influence the risk and etiology of several major cancers and cardiovascular disease. Our objective was to determine the effect of the MTHFR 677C-->T polymorphism and folate status on the relative rate and extent of in vivo synthesis of DNA precursors. Adequately nourished, healthy women (9 CC, 9 TT) were infused with [3-(13)C]serine and [(13)C(5)]methionine for 9 h before and after 7 wk of consumption of a low-folate diet. Blood was drawn over 5 d for monocyte DNA isolation. Isotopic enrichment of the nucleosides in DNA digests was determined by LC-MS/MS. Maximum thymidine enrichment tended to be higher (P = 0.07) in TT than in CC subjects, suggestive of marginally higher mean thymidylate synthesis. However, the subset of TT subjects who exhibited formyltetrahydrofolate in erythrocytes (an indicator of 1-carbon partitioning) had greater (P = 0.036) thymidine enrichment than CC subjects, who had no erythrocyte formyltetrahydrofolate. Purine enrichment was not affected by genotype or folate depletion. However, the deoxyadenosine to deoxyguanosine enrichment ratio was significantly higher in TT subjects, suggesting a greater relative rate of adenine synthesis. The approximately 40% greater (P = 0.012) labeling of the methyl group of methyldeoxycytidine during folate depletion suggests a change in the origin of this 1-carbon unit. This is the first time that 1-carbon incorporation into human DNA has been measured in vivo after infusion of (13)C-labeled 1-carbon precursors. These findings support the feasibility of further assessment of factors affecting deoxynucleotide synthesis and DNA methylation in human 1-carbon metabolism.
