Single-nucleus RNA sequencing of dorsolateral prefrontal cortex from normal, pathological aging, and Alzheimer’s disease human brains

Project description:We performed single-nucleus RNA sequencing of the dorsolateral prefrontal cortex from 15 normal, pathological aging, and Alzheimer’s disease human brains that varied by APOE and TREM2 genotype to analyze cell-type specific transcriptomic changes across the range of Alzheimer’s disease pathology and genetic risk factors.

Gene expression profiling postmortem dorsolateral prefrontal cortex in schizophrenia

Project description:Schizophrenia-associated anomalies in gene expression in postmortem brain are caused by a combination of genetic and environmental influences. Given the small effect size of common variants it is likely that we may only see the combined impact of some of these at the pathway level in small postmortem studies. However, at the gene level we will see more impact from common environmental risk factors mediated by influential epigenomic modifiers. In this study we examine changes in cortical gene expression to identify regulatory interactions and networks associated with the disorder. Gene expression analysis in post-mortem prefrontal dorsolateral cortex (BA 46) (n=74 matched pairs of schizophrenia, schizoaffective and control samples) was performed using Illumina HT12 gene expression microarrays. Significant gene interaction networks were identified for differentially expressed genes in pathways of neurodevelopmental and oligodendrocyte function.

ANALYSIS OF NETWORKS IN THE DORSOLATERAL PREFRONTAL CORTEX IN CHRONIC SCHIZOPHRENIA: RELEVANCE OF ALTERED IMMUNE RESPONSE

Project description:The dorsolateral prefrontal cortex (DLPFC) is the association area in the anterior part of the frontal lobe and has a crucial role in cognitive functioning and negative symptoms in SZschizophrenia. However, limited information of altered protein networks is available in this region in schizophrenia. We performed a proteomic analysis using single-shot liquid chromatography-tandem mass spectrometry of grey matter of postmortem DLPFC in chronic schizophrenia subjects (n=20) and healthy individuals (n=20) followed by bioinformatic analysis to identify altered protein networks in SZ.

Expression data from human brain dorsolateral prefrontal cortex - including control samples and samples with major depression disorders (30 samples BA9_F)

Project description:Major depressive disorder is a heterogeneous illness with a mostly uncharacterized pathology. Large scale gene expression (transcriptome) analysis and genome-wide association studies (GWAS) for single nucleotide polymorphisms have generated a considerable amount of gene- and disease-related information, but heterogeneity and various sources of noise have limited the discovery of disease mechanisms. As systematic dataset integration is becoming essential, we developed methods and performed meta-clustering of gene coexpression links in 11 transcriptome studies from postmortem brains of human subjects with major depressive disorder (MDD) and non-psychiatric control subjects. We next sought enrichment in the top 50 meta-analyzed coexpression modules for genes otherwise identified by GWAS for various sets of disorders. One coexpression module of 88 genes was consistently and significantly associated with GWAS for MDD, other neuropsychiatric disorders and brain functions, and for medical illnesses with elevated clinical risk of depression, but not for other diseases (See publication for details). 30 total samples in 15 pairs were analyzed in postmortem tissue from the dorsolateral prefrontal cortex.

Whole transcriptome RNA-seq of undiseased human prefrontal cortex

Project description:We report the application of high-throughput RNA sequencing to the human prefrontal cortex. The brain dataset was obtained by sequencing total RNAs extracted from the dorsolateral prefrontal cortex of five deceased human patients with no apparent pathology, followed by depletion of ribosomal RNA to obtain all non-rRNA coding and non-coding RNAs in the human brain transcriptome. Five samples were sequenced, four coming from frozen brain tissue (frontal cortex) of deceased female human patients with no remarkable pathology, and one from a male patient with no remarkable pathology.
