In the present study we have investigated the association of three single nucleotide polymorphisms in glutathione peroxidase (GPx) genes GPX1 rs1050450 (P198L), GPX3 rs2070593 (G930A) and GPX4 rs713041 (T718C) with the risk of cerebral stroke (CS) in patients with essential hypertension (EH). A total of 667 unrelated EH patients of Russian origin, including(More)
Oxidative stress resulting from an increased amount of reactive oxygen species and an imbalance between oxidants and antioxidants has been implicated in pathogenesis of cerebral stroke. The purpose of this study was to investigate the relationship between common polymorphisms of glutathione S-transferase M1, T1, and P1 genes and risk of stroke in(More)
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(More)
AIM Reactive oxygen species an important role in the pathogenesis of cerebrovascular disorders. NAD(P)H oxidases are one of the main sources of superoxide anions in cerebral arteries. NAD(P)H oxidase represents molecular complex and its p22phox subunit is coded by the CYBA gene located in the long arm of chromosome 16. We studied the association between the(More)
The purpose of this study was to investigate whether a common polymorphism -463G>A (rs2333227) in the promoter of myeloperoxidase (MPO) gene, an oxidant enzyme producing hypohalogenic radicals, is associated with the risk of essential hypertension (EH) in Russian population. A total of 2044 unrelated subjects including 1256 EH patients and 788 normotensive(More)
The cardio-ankle vascular index is a measure of arterial stiffness, whereas oxidative stress underlies arterial pathology. This study aimed to investigate the association between the cardio-ankle vascular index and antioxidant-related gene polymorphisms in young Russians. A total of 89 patients (mean age, 21.6 years) were examined by the cardio-ankle(More)
AIM To investigate whether the functionally relevant -844G>A promotor polymorphism in the catalase (CAT) gene is associated with the development of essential hypertension (EH). SUBJECTS AND METHODS The investigation enrolled 2,339 unrelated ethnic Russian people, including 1,269 EH patients and 770 apparently healthy individuals. Genotyping of CAT -844G>A(More)
OBJECTIVE The present study was designed to investigate whether genetic polymorphisms of the aryl hydrocarbon receptor (AHR) signaling pathway are involved in the molecular basis of essential hypertension (EH). METHODS A total of 2160 unrelated Russian individuals comprising 1341 EH patients and 819 healthy controls were recruited into the study. Seven(More)
Numerous studies demonstrated an importance of cytochrome P-450 epoxygenase pathway of arachidonic acids metabolism for the pathogenesis of essential hypertension (EH). The present study was designed to investigate whether common single-nucleotide polymorphisms (SNP) of CYP2C gene subfamily such as CYP2C8 (rs7909236 and rs1934953), CYP2C9 (rs9332242), and(More)
AIM A noninvasive approach to assess atherosclerosis in young people is of great concern. The cardio-ankle vascular index (CAVI) and ankle-brachial index (ABI) reflect the arterial conditions, although the CAVI has not fully been studied in Russian populations. This study aimed to determine the CAVI and ABI in young Russians, to compare these findings with(More)
