DNA methylation in postmortem brain samples from autism cases and controls

ABSTRACT: We used the Illumina 450KMethylation BeadChip to measure DNA methylation at 485,512 loci across the genome for 40 postmortem brain samples. The purpose of our study was to identify differentially methylated regions (DMRs) associated with autism. Samples included 16 temporal cortex brain tissue samples (6 cases and 10 controls), 11 prefrontal cortex brain tissue samples (6 cases and 5 controls), and 13 cerebellum brain tissue samples (7 cases and 6 controls).

Transcription profiling of human adult postmortem brain tissue from subjects with bipolar disorder and healthy controls

Project description:This SuperSeries is composed of the following subset Series:; GSE5388: Adult postmortem brain tissue (dorsolateral prefrontal cortex) in subjects with bipolar disorder; GSE5389: Adult postmortem brain tissue (ortibtofrontal cortex) in subjects with bipolar disorder; Bipolar affective disorder is a severe psychiatric disorder with a strong genetic component but unknown pathophysiology. We used microarray technology (Affymetrix HG-U133A GeneChips) to determine the expression of approximately 22 000 mRNA transcripts in post-mortem brain tissue (dorsolateral prefrontal cortex and orbitofrontal cortex) from patients with bipolar disorder and matched healthy controls. Experiment Overall Design: Refer to individual Series

Transcription profiling of human adult postmortem brain tissue from Down syndrome and healthy control subjects

Project description:Down syndrome (DS) is the result of trisomy chromosome 21 but the mechanisms by which the genotype leads to the characteristic disease phenotype are unclear. We performed a microarray study using human adult brain tissue (dorsolateral prefrontal cortex) from DS subjects and healthy controls to characterise for the first time the human adult Down syndrome brain Experiment Overall Design: RNA extracted from human postmortem brain tissue from adult subjects with Down syndrome and healthy controls was hybridised to Affymetrix HG-U133A GeneChips to identify differentially expressed genes in the disease state.

Profiling Transcriptomic Alterations in Postmortem Prefrontal Cortex Tissues of Individuals with Alcohol Use Disorders

Project description:Analysis of transcriptiomic alternations related with alcohol use disorders (AUDs). The hypothesis is that chronic alcohol consumption might alter genome-wide gene expression patterns. The results suggest that differential gene expression in the prefrontal cortex is implicated in neuroadaptations to alcohol. Total RNAs were extracted from postmortem prefrontal cortex tissues from 23 AUD cases and 23 matched controls. Both AUD cases and matched controls were assessed with DSM-IV.

Transcription profiling of human postmortem brain samples with and without FTLD-U

Project description:FTLD-U is the most common pathological correlate of the neurodegenerative dementia frontotemporal dementia; We used microarrays to perform global expression profiling of FTLD-U brain samples Experiment Overall Design: Postmortem brain samples were isolated from normal controls, FTLD-U patients with progranulin gene mutations (progranulin) and FTLD-U patients without progranulin gene mutations (sporadic). Regional dissections were carried out from frontal cortex, hippocampus, and cerebellum.

Project description:Analysis of methylomic alternations related with alcohol use disorders (AUD). The hypothesis is that chronic alcohol consumption might alter genome-wide DNA methylation patterns. The results suggest that differential DNA methylation might be invovled in neuradaptations to alcohol. Genomic DNA was extraced from postmortem prefrontal cortex tissues of 23 AUD cases and 23 matched controls. Both AUD cases and matched controls are assessed with DSM-IV
