Matrix metalloproteinase 10 gene polymorphism and atherothrombotic cerebral infarction risk in a Han Chinese population.

ABSTRACT: BACKGROUND:Matrix metalloproteinase 10 (MMP10) plays an important role in ischemic stroke and has a close relationship with some stroke risk factors. The aim of this study was to investigate the relationship between two single nucleotide polymorphisms (SNP) in the exon regions of the MMP10 gene and atherothrombotic cerebral infarction risk. METHODS:Five hundred and thirty-seven hospital-based patients who had suffered first atherothrombotic cerebral infarction and 580 unrelated healthy controls were enrolled. Demographic and clinical features of the subjects were recorded, and two polymorphisms, rs17435959 (G>C), rs17293607 (C>T) were chosen to be genotyped by real-time polymerase chain reaction-restriction TaqMan probes using the ABI 7300 TaqMan platform. RESULTS:There were several clinical parameters, such as blood pressure, fasting blood glucose, total cholesterol, homocysteine, as well as carotid plaque and smoking, but not average age and sex ratios that showed significant differences between patients and control subjects. For rs17435959, there was no significant difference between the ischemic stroke group and the healthy control group in genotype frequency (OR=1.295, P=0.187, 95% CI (0.882-1.899)) or allele frequency (OR=1.267, P=0.202, 95% CI (0.881-1.823)). Moreover, in smoking, none smoking, having carotid plaque, no carotid plaque, male or female subtypes, there was significant difference between patients and control subjects in genotype frequencies or allele frequencies. The minor allele frequency of rs17293607 was 0.92%, prohibiting further study of this allele. CONCLUSIONS:These findings suggest that the rs17435959 SNP may not associated with atherothrombotic cerebral infarction risk. We also found that rs17293607 is not polymorphic in our study population.

Project description:Background and purposeAtherothrombotic cerebral infarction [atherothrombotic stroke (ATS)] shares common risk factors and pathophysiological mechanisms with coronary artery disease (CAD), and both diseases appear to have common susceptibility loci. The muscle RAS oncogene homolog gene (MRAS) has been identified as a susceptibility locus for CAD and is implicated in atherosclerosis. The aim of this study was to elucidate whether the single-nucleotide polymorphisms (SNPs) and haplotypes of MRAS are associated with increased risk of ATS in a population of Han Chinese.MethodsA case-controlled association study was conducted in which only patients with ATS (identified as a major subtype in the Korean modification of the Trial of Org 10172 in Acute Stroke Treatment classification) were enrolled. Subgroup analyses were carried out to determine whether the effect of the MRAS polymorphism was specific to age and gender among the subjects.ResultsIn total, 194 ATS and 186 control subjects were included in the present study. Two tagging SNPs were identified in MRAS (rs40593 and rs3755751). A multivariate regression analysis revealed a positive association between rs40593 and ATS under dominant and additive models after adjustment for covariates. Subgroup analyses revealed that there were no gender differences with respect to allele or genotype frequencies between the groups. The AG genotype for rs40593 (p=0.028), the CT genotype for rs3755751 (p=0.036), and G-allele carriers (AG plus GG) for rs40593 (p=0.015) exhibited a significant protective effect among those aged ≥45 years. For the haplotype analysis, ATS subjects aged ≥45 years had a higher frequency of the ACAC haplotype (76.0%) than the controls (68.1%; p<0.05); that haplotype was associated with an increased risk of ATS.ConclusionsThe obtained data suggest a positive association between MRAS and ATS among the Han Chinese. Further studies should be performed with larger sample and among different ethnic populations, and gene-gene or gene-environment interactions should be considered.
