Joint effect of glutathione S-transferase genotypes and cigarette smoking on idiopathic male infertility

Inconsistent results of association studies investigated the role of glutathione S-transferase genes in idiopathic male infertility may be explained by ethnical differences in gene-gene and gene-environment interactions. In this study, we investigated a joint contribution of GSTM1, GSTT1 and GSTP1 gene polymorphisms and cigarette smoking to the risk of idiopathic infertility in Russian menyesBelgorod State National Research Universit

Key findings of research are to develop the functional model of the development mechanism of financial resources of the housing mortgage lending; to clarify the understanding of mortgage and housing mortgage lending. The article also shows the scheme of public-private partnerships in order to enhance the formation of financial resources for the construction of affordable housing for the population. The contents of the article may be used in the practice of commercial banks in attracting financial resources and regional authorities in order to improve the housing supply. © 2016 Savinova et al

Genetic variation at the catalytic subunit of glutamate cysteine ligase contributes to the susceptibility to sporadic colorectal cancer: a pilot study

Glutathione is a tripeptide detoxifying a variety of exogenous and endogenous free radicals and carcinogens, and a deficiency of glutathione is associated with an increased host susceptibility to oxidative stress, a pathological condition implicated in the development and progression of cancer. The catalytic subunit of glutamate-cysteine ligase (GCLC) is an enzyme responsible for the initial and rate-limiting step of glutathione biosynthesi

Влияние полиморфизма Pro198Leu гена глутатионпероксидазы 1-го типа на риск развития аллергической бронхиальной астмы у мужчин

The purpose of our pilot study was to investigate the association between Pro198Leu polymorphism in the glutathione peroxidase-1 gene (GPX1) and susceptibility to atopic and non-atopic asthma in Russian residents of the Central region of Russia. Blood samples from 213 asthmatics and 205 healthy controls matched on gender and age were analyzed for P198L polymorphism of the GPX1 gene using PCR-RFLP methods. The association of 198Pro/Leu GPX1 genotype (OR = 1,53; p = 0,05) with susceptibility to atopic BA was found. However, the 198Pro/Leu genotype of the glutathione peroxidase-1 gene was found to be associated with atopic BA in males only (OR = 2,21; p = 0,01).Впервые изучена связь полиморфизма Pro198Leu гена глутатионпероксидазы-1 (GPX1) с развитием аллергической и неаллергической форм бронхиальной астмы (БА). Материалом для исследования послужила популяционная выборка русских жителей ЦентральноЧерноземного региона России (213 больных БА и 205 здоровых добровольцев). Генотипирование полиморфизма Pro198Leu гена GPX1 проводилось методом полимеразной цепной реакции (ПЦР) и посредством анализа полиморфизма длин рестрикционных фрагментов (ПДРФ). Установлено, что частота гетерозигот 198L/P была выше среди больных аллергической БА, чем среди здоровых индивидов (OR = 1,53; p = 0,05). Однако обнаруженная нами впервые ассоциация полиморфизма Pro198Leu гена GPX1 с аллергической БА была характерна только для мужчин (OR = 2,21, p = 0,01)

Adult onset asthma and interaction between genes and active tobacco smoking: The GABRIEL consortium.

BACKGROUND: Genome-wide association studies have identified novel genetic associations for asthma, but without taking into account the role of active tobacco smoking. This study aimed to identify novel genes that interact with ever active tobacco smoking in adult onset asthma. METHODS: We performed a genome-wide interaction analysis in six studies participating in the GABRIEL consortium following two meta-analyses approaches based on 1) the overall interaction effect and 2) the genetic effect in subjects with and without smoking exposure. We performed a discovery meta-analysis including 4,057 subjects of European descent and replicated our findings in an independent cohort (LifeLines Cohort Study), including 12,475 subjects. RESULTS: First approach: 50 SNPs were selected based on an overall interaction effect at p<10-4. The most pronounced interaction effect was observed for rs9969775 on chromosome 9 (discovery meta-analysis: ORint = 0.50, p = 7.63*10-5, replication: ORint = 0.65, p = 0.02). Second approach: 35 SNPs were selected based on the overall genetic effect in exposed subjects (p <10-4). The most pronounced genetic effect was observed for rs5011804 on chromosome 12 (discovery meta-analysis ORint = 1.50, p = 1.21*10-4; replication: ORint = 1.40, p = 0.03). CONCLUSIONS: Using two genome-wide interaction approaches, we identified novel polymorphisms in non-annotated intergenic regions on chromosomes 9 and 12, that showed suggestive evidence for interaction with active tobacco smoking in the onset of adult asthma

The flavin-containing monooxygenase 3 gene and essential hypertension: The joint effect of polymorphism E158K and cigarette smoking on disease susceptibility

Gene encoding flavin-containing monooxygenase 3 (FMO3), a microsomal antioxidant defense enzyme, has been suggested to contribute to essential hypertension (EH). The present study was designed to investigate whether common functional polymorphism E158K (rs2266782) of the FMO3 gene is associated with EH susceptibility in a Russian population. A total of 2 995 unrelated subjects from Kursk (1 362 EH patients and 843 healthy controls) and Belgorod (357 EH patients and 422 population controls) regions of Central Russia were recruited for this stud

Synergism between the N-acetyltransferase 2 gene and oxidant exposure increases the risk of idiopathic male infertility

N-acetyltransferase (NAT2) is a phase-II xenobiotic-metabolizing enzyme participating in the detoxification of toxic arylamines, aromatic amines and hydrazines. The present study was designed to investigate whether two common single-nucleotide polymorphisms (SNP) of the NAT2 gene (481C>T, rs1799929; 590G>A, rs1799930) are associated with susceptibility to idiopathic male infertility and to assess if the risk is modified by oxidant and antioxidant exposures. A total 430 DNA samples (203 infertile patients and 227 fertile men) were genotyped for the polymorphisms by PCR and restriction fragment length polymorphism. No association was found between the NAT2 polymorphisms and idiopathic male infertilit
