Association between ACE gene polymorphisms and Alzheimer's disease in Han population in Hebei Peninsula.

ABSTRACT: PURPOSE:This study aimed to detect the association between angiotensin I converting enzyme (ACE) gene polymorphisms (rs4343 and rs1800764) and Alzheimer's disease (AD) in Han population in Hebei Peninsular. METHODS:We recruited 113 AD patients and 142 healthy individuals in this case-control study. Differences of genotypes, alleles and haplotypes in two groups were analyzed by chi-square test. Besides, odds ratios (ORs) and 95% confidence intervals (CIs) were used to represent the relative risk of AD. At last, the analyses of linkage disequilibrium and haplotypes were done with HaploView software. RESULTS:In the analyses of genotypes and alleles of ACE polymorphisms (rs4343 and rs1800764) in AD, no obvious association was found between genotypes and alleles of rs4343 with the susceptibility of AD. In rs1800764 polymorphism, only C allele had significant association with AD susceptibility (P=0.035, OR=1.473, 95% CI=1.027-2.111), which suggested that rs1800764 C allele is the susceptible allele of AD. Linkage disequilibrium analysis between rs4343 and rs1800764 polymorphisms indicated there existed 3 haplotypes (A-T, A-C and G-C). A-C haplotype might associate with the susceptibility of AD (P=0.023, OR=2.591, 95% CI=1.111-6.043). CONCLUSION:Rs4343 polymorphism of ACE gene had no relationship with AD risk. C allele of rs1800764 could increase the susceptibility of AD. A-C haplotype of rs4343 and rs1800764 polymorphisms might increase the risk of AD, and the ORs was 2.591.

Project description:AimsDilated cardiomyopathy (DCM) belongs to the common types of cardiomyopathies. The pathogenesis remains unclear despite the fact that various genes have been found associated with DCM. MMP2 is a zinc-dependent and calcium-containing secreted endoproteinases, which could cleave a broad spectrum of substrates including extracellular matrix components and cytokines. It has proved to play an important role in the cardiovascular diseases. This study aimed to investigate the potential role of MMP2 gene polymorphisms in DCM susceptibility and prognosis in a Chinese Han population.Methods and resultsA total of 600 idiopathic DCM patients and 700 healthy controls were enrolled. Patients with contact information were followed up for a median period of 28 months. Three tagged single nucleotide polymorphisms (rs243865, rs2285052, and rs2285053) in the promoter of MMP2 gene were genotyped. A series of function analysis were conducted to illuminate the underlying mechanism. The frequency of rs243865-C allele was increased in DCM patients when compared with healthy controls (P = 0.001). Genotypic frequencies of rs243865 were associated with the susceptibility of DCM in the codominant, dominant, and overdominant models (P < 0.05). Besides, rs243865-C allele presented a correlation with the poor prognosis of DCM patients in both dominant (HR = 2.0, 95% confidence interval [CI] = 1.14-3.57, P = 0.017) and additive (HR = 1.85, 95% CI = 1.09-3.13, P = 0.02) model. The statistical significance remained after adjustment for sex, age, hypertension, diabetes, hyperlipidaemia, and smoking status. There were significant differences in left ventricular end-diastolic diameter and left ventricular ejection fraction between rs243865-CC and CT genotypes. Functional analysis indicated that rs243865-C allele increased luciferase activity and the mRNA expression level of MMP2 by facilitating ZNF354C binding.ConclusionsOur study suggested that MMP2 gene polymorphisms were associated with DCM susceptibility and prognosis in the Chinese Han population.
