Project description:A common and severe neural tube defect (NTD) phenotype, myelomeningocele (MM), results from the defective closure of the caudal end of the neural tube with herniation of the spinal cord and meninges through the vertebral column. The exact mechanisms for NTDs are unknown, but excessive oxidative stress, particularly in association with maternal diabetes, has been postulated as a mechanism for MM.The SNPlex Genotyping (ABI, Foster City, CA) platform was used to investigate single nucleotide polymorphisms (SNPs) across the superoxide dismutase (SOD) 1 and 2 genes to assess their association with MM risk. The study population included 329 trio (affected child and both parents) and 281 duo (affected child and one parent) families. Only cases with documented MM were studied. Seventeen SNPs across the SOD1 and SOD2 genes met the quality-control criteria to be considered for statistical analysis. Genetic association was assessed using the family-based transmission disequilibrium test in PLINK (a genome association analysis toolset).Four SNPs in the SOD1 gene (rs 202446, rs202447, rs4816405, and rs2070424) and one SNP in the SOD2 gene ( rs5746105) [corrected] appeared to be associated with MM risk in our population. After adjusting for multiple testing, these SNPs remained significant.This study provides the first genetic evidence to support association of myelomeningocele with superoxide scavenging. The rare alleles of the five specific SNPs within SOD1 and SOD2 appear to confer a protective effect on the susceptibility for MM risk in the MM population tested. Further evaluation of the roles of superoxide scavenging and neural tube development is warranted.

Project description:PurposeDrug-induced liver injury (DILI) is a serious issue often leading to discontinuation of the proper regimen of antituberculosis drugs (ATD). Previous studies have suggested that antioxidant enzymes play an important role in DILI.MethodsWe explored whether polymorphisms in superoxide dismutase genes, including Cu/Zn superoxide dismutase (SOD1), manganese superoxide dismutase (SOD2) and extracellular superoxide dismutase (SOD3) are associated with ATD-induced hepatitis. Genotype distributions of four single nucleotide polymorphisms (SNPs) in three genes (rs2070424, SOD1; rs4880, SOD2; rs2536512, and rs1799895, SOD3) were compared between 84 patients with ATD-induced hepatitis and 237 patients tolerant to ATD.ResultsIntron SNP rs2070424 of SOD1 showed a significant association with ATD-induced hepatitis. The frequency of genotypes carrying minor alleles (GA or GG) was significantly higher in the case group than that of controls (P=0.019, OR=2.26, 95% CI 1.14-4.49). For the other SNPs of SOD2 and SOD3, there were no differences in genotype frequencies between ATD-induced hepatitis and ATD-tolerant controls.ConclusionsThese findings suggest that rs2070424 of SOD1 is significantly associated with ATD-induced hepatitis. This genetic variant may be a risk factor for ATD-induced hepatitis in individuals from Korea.

Project description:Little is known about the contribution of each of the three superoxide dismutase isozymes (SODs) to the total SOD activity in extracellular fluids. This study was aimed to investigate the alterations in concentration/activity of (SODs) in plasma, in context of sex, obesity, exposition to cigarette smoke, and genotypic variability of five selected single nucleotide polymorphisms (SNPs) in genes SOD1, SOD2, SOD3. Men showed higher SOD1 concentration, lower SOD3 concentration and higher total antioxidative capacity (TAC) values. Intersexual variability was observed in concentration of copper, zinc, and cadmium. The obese showed higher total oxidative capacity regardless of sex. An increase in SOD2 activity was coexistent with obesity in men, and exposition to cigarette smoke in non-obese individuals. Additionally, in state of this exposition, Cu,Zn-SOD contribution to the total SOD was lower. Interestingly, over 90% of the obese were of C/T genotype of rs4880 (SOD2). Non-obese of T/T genotype (rs4880) were of lower total SOD activity due to decrease in both Cu,Zn-SOD and Mn-SOD activities. SNP rs2234694 was associated with differences in concentration of SODs, depending on obesity status. Correlations indicate that both TAC and SODs, together, may adapt to insulin resistance and inflammation-derived oxidative stress found in obesity. This topic should be further investigated.

Project description:Some epidemiological studies have investigated the relationship between genetic polymorphisms of DRD2, COMT, DBH, and MAO-A and migraine susceptibility, but the results are still inconsistent. Thus, our aim was to further assess the association through a meta-analysis.We examined 5 single nucleotide polymorphisms (SNPs) in 4 genes, including DRD2 rs1799732 and rs6275, DBH rs7239728, MAI-A-VNTR, and COMT rs4680, and performed a meta-analysis of 11 published case-control studies including 3138 cases and 4126 controls. Odd ratios (ORs) with 95% confidence intervals (95% CIs) were used to evaluate the association between the 5 genetic polymorphisms and migraine susceptibility.There was no significant relationship between migraine susceptibility and 4 genetic polymorphisms of DRD2 rs1799732 and rs6275, DBH rs7239728, and MAO-A-VNTR. Nevertheless, decreased risk of migraine was observed to be in association with COMT rs4680 polymorphism in overall analysis (AA vs. GG + GA: OR = 0.76, 95% CI = 0.60-0.97, PHet > 0.642, I = 0), and in Caucasian group after subgroup analysis (AA vs. GG + GA: OR = 0.75, 95% CI = 0.58-0.96, PHet > 0.433, I = 0).Studied polymorphisms of DRD2, DBH, and MAO-A genes may not be associated with migraine susceptibility. However, COMT rs4680 polymorphism may decrease the risk of migraine, especially in Caucasians. The failure to evaluate environmental influence and provide adjusted effect size estimates highlights the need for additional studies in a large number to take these factors into consideration, thus better elucidating the role of the genes tested in migraine.

Project description:PURPOSE:The association between GRIA1 rs548294 G>A and rs2195450 C>T polymorphisms and migraine risk has been reported in several case-control studies. However, the results of studies are inconsistent. Thus, we conducted a meta-analysis to more precisely estimate the association of the two polymorphisms with migraine risk. METHODS:Eligible studies were retrieved and screened from the online databases (EMBASE, PubMed, Web of Science, Wanfang, and Chinese National Knowledge Infrastructure). The pooled odds ratio (OR) with corresponding 95.0% confidence intervals (CIs) was assessed using random- or fixed-effects model. RESULTS:A total of 1233 cases and 1374 controls from four eligible studies were included. The pooled analysis showed that GRIA1 rs548294 G>A polymorphism was not significantly associated with migraine risk. GRIA1 rs2195450 C>T polymorphism was significantly associated with migraine risk under heterozygous model (CT vs. CC, OR = 1.23, 95%CI = 1.02-1.48, P Z = 0.03). Further subgroup analysis based on ethnicity showed a significant association of GRIA1 rs2195450 C>T polymorphism with migraine risk in Asian population, but not in Caucasian population. CONCLUSIONS:Our results indicates that GRIA1 rs2195450 C>T polymorphism is significantly associated with migraine risk. However, the number of studies included in the meta-analysis was small. Thus, more high quality case-control studies with a large sample size are still required to confirm these findings.

Project description:Increased free radical production had been documented in group A (?-hemolytic) streptococcus infection cases. Comparing 71 erysipelas patients to 55 age-matched healthy individuals, we sought for CAT, SOD1, and SOD2 single polymorphism mutation (SNPs) interactions with erysipelas' predisposition and serum cytokine levels in the acute and recovery phases of erysipelas infection. Whereas female patients had a higher predisposition to erysipelas, male patients were prone to having a facial localization of the infection. The presence of SOD1 G7958, SOD2 T2734, and CAT C262 alleles was linked to erysipelas' predisposition. T and C alleles of SOD2 T2734C individually were linked to patients with bullous and erythematous erysipelas, respectively. G and A alleles of SOD1 G7958A individually were associated with lower limbs and higher body part localizations of the infection, respectively. Serum levels of IL-1?, CCL11, IL-2R?, CXCL9, TRAIL, PDGF-BB, and CCL4 were associated with symptoms accompanying the infection, while IL-6, IL-9, IL-10, IL-13, IL-15, IL-17, G-CSF, and VEGF were associated with predisposition and recurrence of erysipelas. While variations of IL-1?, IL-7, IL-8, IL-17, CCL5, and HGF were associated with the SOD2 T2734C SNP, variations of PDFG-BB and CCL2 were associated with the CAT C262T SNP.

Project description:Population-based studies have established an association between migraine and cardiovascular disease (CVD). We sought to investigate whether genetic variants implicated in CVD are associated with migraine. We performed an association study among 25,713 women participating in the Women's Health Study, with information on 77 previously characterized polymorphisms. Migraine and migraine aura status were self-reported. We used logistic regression to investigate the genotype-migraine association. At baseline, 4705 (18.3%) women reported history of migraine; 39.6% of the 3306 women with active migraine indicated aura. Regarding any history of migraine, the multivariable-adjusted odds ratios (95% confidence intervals) for TNF rs673 were 0.52 (0.30 to 0.89), for TGFB1 rs1800469 0.93 (0.89 to 0.98), and for CCR2 rs1799864 1.12 (1.03 to 1.21). Among active migraine with aura, the odds ratios (95% confidence intervals) were 1.35 (1.0 to 1.81) for TNF rs1800750, 1.13 (1.02 to 1.26) for TNF rs1800629, and 1.22 (1.07 to 1.40) for CCR2 rs1799864; among active migraine without aura, 0.9 (0.84 to 0.97) for TGFB1 rs1800469, 1.13 (1.01 to 1.27) for NOS3 rs3918226, and 1.12 (1.02 to 1.24) for IL9 rs2069885. After correction for multiple testing using the false discovery rate, none of the results remained significant. Our data suggest an association of polymorphisms implicated in inflammatory pathways and migraine in women. TNF, CCR2, TGFB1, NOS3, and IL9 warrant further investigation.This article presents results from an association study of 77 polymorphisms, implicated in CVD, and migraine. Variants in TNF, CCR2, TGFB1, NOS3, and IL9 were found to be associated with migraine but did not remain significant after adjustment for multiple testing. Variations in these genes warrant further investigation.

Project description:INTRODUCTION: Migraine is a chronic, neurovascular polygenic disease where genetic and environmental factors are involved in its etiology. Dysfunction of neuronal ion transportation can provide a model for predisposition for common forms of migraine. Mutations in genes encoding ion channels disturb the rhythmic function of exposed tissue that may also explain the episodic nature of migraine. Our aim was to study the single nucleotide polymorphisms of CACNA1A gene in migraine patients. MATERIALS AND METHODS: The subjects were the patients of migraine, in the age range of 18-80 years, diagnosed by a Neurologist, as per the diagnostic criteria of International Headache Society (IHS) Classification 2004 after excluding other causes of headache by clinical examination and relevant investigations. The controls were the age and sex matched healthy persons from the same population excluding the relatives of patients. Only those patients and the controls, who voluntarily participated in the study, were taken and their blood samples were taken for the study. Deoxyribonucleic acid (DNA) extraction was performed according to the manufacturer's protocol for Qiagen DNA extraction kits (Qiagen, Hilden, NRW, Germany). DNA content was quantified by spectrophotometric absorption (Nanodrop Spectrophotometer, BioLab, Scoresby, VIC, Australia). Polymerase chain reaction was performed using an iCycler Thermal Cycler (Bio.Rad, Hercules, CA, USA). The polymorphic analysis of CACNA1A gene was carried out by two methods: Restriction fragment length polymorphism and sequencing. RESULTS: The study included a total of 25 patients of migraine, diagnosed on out-patient department basis as per IHS Classification 2004 and compared with age and sex matched 25 healthy controls. Most of the patients 23 (92%) were below the age of 50 years. 20 of the patients (80%) were females and 5 (20%) were males. The polymorphic analysis of CACNA1A gene revealed the presence of only the wild form of the gene for the codon E993V in both case and control groups. CONCLUSION: In our study, we could not find any polymorphism of CACNA1A gene in the selected patients. Instead the wild type of genotype was found in both patients and controls. This negative result presented here, implies that if the CACNA1A gene is involved in typical migraine (with and without aura), its contribution is very modest and therefore difficult to discern. Nevertheless, there are other genes that could be considered potential candidates for typical migraine susceptibility for which further research is needed.

Project description:To investigate the role of three common polymorphisms in the beta2-adrenoceptor gene in migraine.Migraine has been associated with increased risk of cardiovascular disease and asthma in which beta2-adrenoceptors play an important role; beta-adrenoceptor antagonists are used in migraine prevention. However, the role of variants in the beta2-adrenoceptor gene in migraine is unclear.Association study among 23,753 white women, participating in the Women's Health Study, for whom we had information on migraine at baseline and genotype status of the polymorphisms rs1042713 (Gly16Arg), rs1042714 (Gln27Glu), rs1800888 (Thr164Ile). Migraine was self-reported and we distinguished between any history of migraine, active migraine with and without aura, and prior migraine (history of migraine but not active migraine) in our analyses.At baseline 4339 women reported any history of migraine. Of these, 3041 had active migraine (1221 migraine with aura, 1820 migraine without aura) and 1298 prior migraine. No migraine was reported by 19,414 women. Genotype- and haplotype-based analyses did not show an association of any of the gene variants tested with any history of migraine. The multivariable-adjusted odds ratios (ORs) (95% confidence intervals) for any history of migraine in the additive model were 1.0 (0.96-1.05) for rs1042713, 1.0 (0.95-1.05) for rs1042714, and 0.84 (0.68-1.05) for rs1800888. In the haplotype analysis the ORs ranged from 0.83 (0.67-1.03) to 1.01 (0.94-1.07) with Gly16-Glu27-Thr164 as the reference. We also did not find associations in the genotype- and haplotype-based analyses within migraine-specific subgroups.Our results do not support a role of 3 investigated polymorphisms in the beta2-adrenoceptor gene in migraine pathophysiology.
