Hypomethylation of SNCA in blood of patients with sporadic Parkinson's disease
چکیده انگلیسی
SNCA is a pathogenic gene identified in rare familial PD, and over-expression of SNCA was suggested in the pathogenesis of familial and sporadic PD. Rep1 polymorphism of SNCA was associated with susceptibility to sporadic PD and SNCA expression in intro and in vivo. Hypomethylation in SNCA intron-1 was associated with increased SNCA expression and was observed in postmortem brains of patients with sporadic PD. We studied the methylation status of SNCA intron-1, SNCA mRNA levels and Rep1 genotypes in PBMCs of 100 sporadic PD patients and 95 controls and explored the relationship between DNA methylation, mRNA expression and Rep1 genotypes. Hypomethylation of SNCA intron-1 was detected in PBMCs of PD patients, and DNA methylation levels were associated with Rep1 polymorphism. The shorter allele was associated with higher level of SNCA intron-1 methylation, and genotypes carrying the shorter allele showed significantly higher methylation level of SNCA intron-1 than genotypes carrying the longer allele. However, SNCA mRNA levels were not associated with disease status, Rep1 polymorphism or DNA methylation of SNCA intron-1 in our study.
