OBJECTIVE: To investigate the association of the gene polymorphisms of: angiotensinogen (AGT), renin (REN), angiotensin II receptor 1 (AT1R) and angiotensin II receptor 2 (AT2R), in the pathogenesis of PE in South African Black women. METHODOLOGY (STUDY DESIGN): 603 pregnant women; 246 normotensive and 357 with PE (early-onset=187, late-onset=170), were recruited. Each study group was subdivided into HIV infected and uninfected groups. The distribution and frequencies of gene polymorphisms of AGT (M235T), REN (C-5312T), AT1R (A1166C) and AT2R (C3123A) were determined in purified DNA by Real Time Polymerase Chain Reaction...

The renin-angiotensin (RAS) pathway has an important role in the etiology of heart failure and given the importance of RAS as a therapeutic target in various cardiomyopathies, genetic polymorphisms in the RAS genes may modulate the risk and severity of disease in cardiomyopathy patients. In the present study, we examined the association of RAS pathway gene polymorphisms, angiotensin converting enzyme (ACE), angiotensinogen (AGT), and angiotensin receptor type 1 (AGTR1) with risk and disease severity in Asian Indian idiopathic cardiomyopathy patients...

The C allele of the M235T (rs699) polymorphism of the AGT gene correlates with higher levels of angiotensin II and has been associated with power and strength sport performance. The aim of the study was to investigate whether or not selected power-related variables and their response to a 12-week program of aerobic dance training are modulated by the AGT M235T genotype in healthy participants. Two hundred and one Polish Caucasian women aged 21 ± 1 years met the inclusion criteria and were included in the study...

BACKGROUND: At present, the patient preparation for IVF needs to undergo a series of planned tests, including the genotyping of single nucleotide polymorphism (SNP) alleles of some genes. In former USSR countries, such investigation was not included in overwhelming majority of health insurance programs and paid by patient. In common, there are prerequisites to the study of more than 50 polymorphisms. An important faced task is to determine the optimal panel for SNP genotyping in terms of price/number of SNP...

OBJECTIVE: Genes encoding key elements of the renin-angiotensin-aldosterone system (RAAS) cascade have been previously but inconsistently associated with blood pressure. Sex-dependency might be important here and functional genetic polymorphisms might exhibit epistatic effects. DESIGN AND METHOD: We assessed variation in the genes encoding renin (REN), angiotensinogen (AGT), angiotensin converting enzyme (ACE), angiotensin II type 1 receptor (AGTR1) and aldosterone synthase (CYP11B2)...

BACKGROUND: With an increase in the discovery of newer genetic loci/polymorphisms in complex multifactorial diseases, there is also an increased need for methods that can simultaneously genotype multiple loci in a cost-effective manner. Using coronary artery disease (CAD) as a model, the study aimed to develop an in-house multilocus assay for simultaneous detection of 17 genetic variants in 11 genes implicated in CAD. METHODS: A multiplex polymerase chain reaction (PCR)-based reverse line blot hybridization (MPCR-RLBH) approach was used, where each DNA sample was amplified using two separate MPCRs, and the alleles were genotyped using covalently immobilized, amino-linked sequence-specific oligonucleotide probes using an enhanced chemiluminescence system...

Endometrial cancer (EC) is the most common gynaecological malignancy and its incidence is increasing. Dysregulation of the endometrial renin-angiotensin system (RAS) could predispose to EC; therefore, we studied the prevalence of RAS single nucleotide polymorphisms (SNPs) in Australian women with EC. SNPs assessed were AGT M235T (rs699); AGTR1 A1166C (rs5186); ACE A240T and T93C (rs4291, rs4292) and ATP6AP2 (rs2968915). They were identified using TaqMan SNP Genotyping Assays. The C allele of the AGTR1 SNP (rs5186) was more prevalent in women with EC (odds ratio (OR) 1...

The rennin-angiotensin-aldosterone system (RAAS) is a critical pathway in regulating blood pressure and salt/water homeostasis, possessing an intimate relationship with the development of systemic artery hypertension (SAH). Once hypertension is considered a risk factor for coronary artery disease (CAD), the RAAS is also related to this pathology. This investigation aimed to analyse if the frequencies of AGT M235T (rs699) and ACE I/D (rs4646994) polymorphisms are associated with CAD and SAH in African-Brazilians and Caucasian-Brazilians...

Activity of the renin-angiotensin Aldosterone system is increased in patients with heart failure (HF). The Angiotensinogen gene and specifically M235T polymorphism has been linked to susceptibility to hypertension, coronary heart disease and atrial fibrillation. Its role in heart failure is not yet sufficiently demonstrated. The aim of the present study was to assess the association between rs699 (M235T) polymorphism and heart failure in terms of diagnosis and prognosis. We included all patients over 20 years old consulting in the Emergency Department for acute dyspnea...

Many studies have suggested that polymorphisms of three key genes (ACE, AGT and CYP11B2) in the renin-angiotensin-aldosterone system (RAAS) play important roles in the development of blood pressure (BP) salt sensitivity, but they have revealed inconsistent results. Thus, we performed a meta-analysis to clarify the association. PubMed and Embase databases were searched for eligible published articles. Fixed- or random-effect models were used to pool odds ratios and 95% confidence intervals based on whether there was significant heterogeneity between studies...

BACKGROUND: Currently, there are no predictive biomarkers for anti-angiogenic strategies in cancer, but response to anti-angiogenic drugs is associated with development of hypertension secondary to treatment. Therefore, this study explored the clinical relevance of genetic polymorphisms in some components of the renin-angiotensin system (RAS). MATERIAL AND METHODS: Genomic DNA was isolated from peripheral blood from 95 metastatic breast or colorectal cancer patients treated with bevacizumab, and AGTR1-A1166C (rs5186), AGT-M235T (rs699) SNPs and ACE I/D (rs4646994) polymorphisms were genotyped using RT-PCR...

Essential hypertension is an important risk factor for the development of cardiovascular disease. We aim in this study to analyse the relationship between AGT M235T gene variant and ACE I/D gene variant with essential hypertension in a sample of the Algerian population of the Oran city. A case-control study has been performed in 145 subjects including; 75 hypertensives and 70 controls from Algerian population of Oran city. Polymerase chain reaction (PCR) combined with restrictive fragment length polymorphism (RFLP) was used to detect the M235T variant of angiotensinogen (AGT) gene and a nested PCR to determine ACE I/D gene variant...

The common angiotensinogen (AGT) M268T polymorphism (rs699; historically referred to as M235T) has been identified as a significant risk factor for cerebrovascular pathologies, yet it is unclear if healthy older adults carrying the threonine amino acid variant have a greater risk for white matter damage in specific fiber tracts. Further, the impact of the threonine variant on cognitive function remains unknown. The present study utilized multiple indices of diffusion tensor imaging (DTI) and neuropsychological assessment to examine the integrity of specific white matter tracts and cognition between individuals with homozygous genotypes of M268T (MetMet n=27, ThrThr n=27)...

INTRODUCTION: The renin-angiotensin system (RAS) has been considered to play an important role in the regulation of blood pressure. This study aimed to investigate the correlation between RAS gene polymorphisms and essential hypertension (EH) in the Chinese Yi ethnic group. MATERIALS AND METHODS: A total of 244 EH subjects and 185 normotensive individuals from the Chinese Yi ethnic group were genotyped for AGT M235T (rs699), AT1R A1166C (rs5186), ACE I/D (rs4340) and ACE G2350A (rs4343) polymorphisms by the polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) method...
