DNA methylation and expression profiles of whole blood in Parkinson’s disease (Methylation)

Project description:Parkinson’s disease (PD) is the second most common age-related neurodegenerative disease. It is presently only accurately diagnosed at an advanced stage by a series of motor deficits, which are predated by a litany of non-motor symptoms manifesting over years or decades. Aberrant epigenetic modifications exist across a range of diseases and are non-invasively detectable in blood as potential markers of disease. We performed comparative analyses of the methylome and transcriptome in blood from PD patients and matched controls. Our aim was to characterize DNA methylation and gene expression patterns in whole blood from PD patients as a foundational step toward the future goal of identifying molecular markers that could predict, accurately diagnose, or track progression of PD. We found that differentially expressed genes (DEGs) were involved in the processes of transcription and mitochondrial function and that PD methylation profiles were readily distinguishable from healthy controls, even in whole blood DNA samples. Differentially methylated regions (DMRs) were functionally varied, including near transcription factor NFYA, receptor tyrosine kinase DDR1, ubiquitin ligase RNF5, acetyltransferase AGPAT1, and vault RNA VTRNA2-1. Expression quantitative trait methylation (eQTM) sites were found at long non-coding RNA PAX8-AS1 and transcription regulator ZFP57, among others. Functional epigenetic modules (FEM) were highlighted by IL18R1, PTPRC, and ITGB2. We identified patterns of altered disease-specific DNA methylation and associated gene expression in whole blood. Our combined analyses extended what we learned from the DEG or DMR results alone. These studies provide a foundation to support characterization of larger sample cohorts, with the goal of building a thorough, accurate and non-invasive molecular PD biomarker.

A splice isoform signature of Parkinson’s disease in peripheral blood

Project description:In these studies, we used splice variant-specific microarrays manufactured by the ExonHit company ( www.exonhit.com) on the Affymetrix platform. The goal was to identify splice isoforms whose expression is altered in whole blood of early-stage Parkinson’s disease patients compared to healthy and neurodegenerative disease controls. The study included 19 cases of Parkinson’s disease (PD) samples, 4 of multiple system atrophy (MSA), 4 progressive supranuclear palsy (PSP) and 10 healthy controls. Thirteen splice variants were confirmed in quantitative polymerase chain reactions and used to classify blinded samples from Parkinson’s disease patients and controls with 90% accuracy and 94% sensitivity.

Genome wide DNA methylation study of Parkinson's disease in whole blood samples

Project description:Genome wide DNA methylation profiling of whole blood and saliva samples in Parkinson's disease (PD) patients and PD-free controls. The Illumina Infinium 450k Human DNA methylation Beadchip was used to obtain DNA methylation profiles. Samples included 335 PD patients and 237 controls with blood DNA.
