Epigenome analysis of Parkinson's disease and control samples from the Systema Genomics Parkinson's disease (SGPD) consortium

Project description:Genome wide DNA methylation association analysis of Parkinson's disease and control samples. The Illumina Infinium 450k Human DNA methylation Beadchip was used to obtain DNA methylation profiles across approximately 450,000 CpGs in blood samples. Samples included 1001 Parkinson's disease cases and 973 controls.

Systematic meta-analysis and replication of genome-wide expression studies of Parkinson's disease: 2

Project description:Systematic meta-analysis and replication of genome-wide expression studies identifies molecular pathways of Parkinson's disease. Examination of substantia nigra from postmortem brains of 8 patients with Parkinson's disease (PD). The substantia nigra samples from 8 PD subjects were obtained from the Human Brain and Spinal Fluid Resource Center, VAMC, Los Angeles, CA, the Mind Unit Brain Bank at the University of Rochester, Rochester, NY, and from Dr. E. Masliah at UCSD, San Diego, CA, and 9 control subjects were obtained from the University of Rochester Alzheimer's Disease Center brain bank. The RNA was extracted using Trizol reagent (Invitrogen), DNAse treated with Qiagen DNAse, and analyzed on a bioanalyzer. The complementary RNA was fragmented and hybridized to Affymetrix human U133A arrays. The total 17 Affymetrix .CEL files were normalized to "all probe sets" in a standardized matter, and scaled to 100 by the MAS5 algorithm implemented in the Bioconductor package.

Transcriptional analysis of multiple brain regions in Parkinson's disease

Project description:Transcriptional analysis of multiple brain regions in Parkinson's disease supports the involvement of specific protein processing, energy metabolism, and signaling pathways, and suggests novel disease mechanisms. This SuperSeries is composed of the following subset Series: GSE20168: Transcriptional analysis of prefrontal area 9 in Parkinson's disease GSE20291: Transcriptional analysis of putamen in Parkinson's disease GSE20292: Transcriptional analysis of whole substantia nigra in Parkinson's disease Refer to individual Series

Systematic meta-analysis and replication of genome-wide expression studies of Parkinson's disease: 3

Project description:Systematic meta-analysis and replication of genome-wide expression studies identifies molecular pathways of Parkinson's disease. Analysis of substantia nigrae from postmortem brains of 6 patients with Parkinson's disease (PD). Results provide insight into the molecular processes perturbed in the PD substantia nigra. Substantia nigra samples from 6 PD and 5 control subjects were obtained. At autopsy, brain hemispheres were frozen in liquid nitrogen and stored at -80C in the Kathleen Price Bryan Brain Bank in the Alzheimer's Disease Research Center at Duke University. Using the RNAgents kit (Promega, Madison, Wis), RNA was extracted from SN and adjacent midbrain tissues. Double-stranded complementary DNA was made with a biotinylated T7(dT)-24 primer. Twenty micrograms of biotinylated complementary RNA was fragmented and hybridized to Affymetrix human genome U133A microarrays. The Affymetrix .CEL files were normalized to "all probe sets" in a standardized matter, and scaled to 100 by the MAS5 algorithm implemented in the Bioconductor package.
