Project description:Analysis of gene expression in two large schizophrenia cohorts identifies multiple changes associated with nerve terminal function. Schizophrenia is a severe psychiatric disorder with a world-wide prevalence of 1%. The pathophysiology of the illness is not understood, but is thought to have a strong genetic component with some environmental influences on aetiology. To gain further insight into disease mechanism, we used microarray technology to determine the expression of over 30 000 mRNA transcripts in post-mortem tissue from a brain region associated with the pathophysiology of the disease (Brodmann area 10: anterior prefrontal cortex) in 28 schizophrenic and 23 control patients. Post-mortem derived BA10 tissue from 28 schizophrenic and 23 control patients were compared. Age, gender, post-mortem delay and pH of brain lysates data were also captured.

Project description:Transcriptional analysis of the superior temporal cortex (BA22) in schizophrenia: Pathway insight into disease pathology and drug development Schizophrenia is a highly debilitating psychiatric disorder which is known to have heritable genetic and environmental components. To gain some insight into the mechanisms underpinning both positive and negative symptoms of the disease, we determined the genome wide expression of mRNA transcripts in post-mortem tissue from the superior temporal cortex (Brodmann Area 22, BA22) in schizophrenic and control patients. The BA22 region is known to mediate the positive pathophysiology of schizophrenia; we compared this to the anterior prefrontal cortex (BA10) from the same subjects, which is known to mediate negative symptoms. Following adjustments for confounding clinical, sample and experimental sources of variation, we carried out gene set enrichment analysis in each region using pathway data. We identified an over-representation of genes involved in cytoskeletal remodelling, neurodevelopment, cell adhesion, cellular signalling, neurotransmission and autophagy. Collectively our analysis indicates a disruption of processes underpinning synaptic plasticity in both regions. Region-specific changes support the dysregulation of distinct pathways in the BA10 and BA22 regions. This may highlight new therapeutic opportunities to treat both negative and positive symptoms of the disease. Post-mortem derived BA22 tissue from schizophrenic and control patients were compared. Age, gender, post-mortem delay and pH of brain lysates data were also captured.

Project description:Post mortem human brain tissue comparison between HD patients and controls from 3 brain regions - cerebellum, frontal cortex [BA4, BA9] and caudate nucleus. Gene expression analysed using linear models from LIMMA package in Bioconductor suite. Experiment Overall Design: Large sample sizes were used to examine brain tissue gene expression at various stages of HD pathology. Three brain regions were profiled, compared and analysed for differential gene expression. The broad aim was to capture early stage gene expression changes in HD brains.

Project description:Extension of glycogene expression pattern analysis in the prefrontal cortical region of Schizophrenic human post-mortem brain samples
| PRJNA138275 | ENA
Project description:The study included post-mortem brain tissue samples from 68 schizophrenia patients and 44 age and sex matched control subjects. Whole transcriptome poly-A selected paired-end RNA sequencing was performed on tissue from prefrontal cortex and orbitofrontal cortex. RNA expression differences were detected between case and control individuals, focusing both on single genes and pathways.
