Role for Functional SOD2 Polymorphism in Pulmonary Arterial Hypertension in a Chinese Population
AbstractThe superoxide dismutase 2 (SOD2) gene is a pivotal part of oxidative stress system, which could induce the onset of pulmonary arterial hypertension (PAH). In this study, we quantified the influence of a SOD2exonic polymorphism (rs4880) on PAH susceptibility. We genotyped this single nucleotide polymorphism (SNP) by TaqMan, and evaluated its association with PAH susceptibility in a case-control study of 460 patients and 530 controls in China. There were significant differences between PAH cases and controls in both CC and TC+CC genotypes (p = 0.013 and p = 0.010, respectively). Furthermore, the number of variant alleles followed a dose-response manner (p trend was 0.023). Besides, the mRNA level and protein expression also indicated that the C allele of this variant decreased the expression of SOD2 gene (p = 0.004 in mRNA level and p = 0.012 in protein level) after the transfection of plasmids containing the different genotype of rs4480. There is significant association between SOD rs4880 polymorphism and the PAH susceptibility, and this polymorphism influenced PAH susceptibility by altering the expression of SOD2. View Full-Text
