Regional Differences in gene expression and promoter usage in aged human brains

Project description:Cap analysis of gene expression (CAGE) and massive parallel sequencing were used to profile the promoterome of aged human brains from five regions, namely: caudate, frontal cortex, hippocampus, putamen and temporal cortex. 25 RNA libraries from post-mortem brain tissue (five caudate, five frontal, 5 hippocampus, 5 putamen, five temporal RNA libraries from seven individuals) were processed using CAGE protocol and CAGE tags derived from the 25 libraries were sequenced with Illumina.

Blood RNAs predictive of molecular changes in the brain and clinical outcome in Parkinson’s disease

Project description:The ability to use blood to predict the outcomes of Parkinson’s disease (PD), including disease progression and development of cognitive and motor complications, would be of enormous clinical value. We undertook deep RNA sequencing from the caudate and putamen of postmortem PD (n=35) and control (n=40) striatum, and compared molecular profiles with clinical features, and samples obtained from antemortem peripheral blood from an independent cohort. Cognitive and motor complications of PD were associated with molecular changes in the caudate (e.g., stress response) and putamen (endothelial pathways) respectively. Later and earlier-onset PD were molecularly distinct, and disease duration was associated with changes in caudate (oligodendrocyte development) and putamen (cellular senescence) respectively. Molecular signatures in the postmortem PD brain were also evident in antemortem peripheral blood, and correlated with clinical disease features. Together, these findings identify molecular signatures in PD patients' brain and blood of potential pathophysiologic and prognostic importance

Transcriptome changes in human post-mortem PD striatum

Project description:We analyzed transcriptome differences in postmortem caudate and putamen from controls (n=40) and PD (n=35) as confirmed by autopsy. Further, we analyzed region specific differences in caudate and putamen associated with clinical variables.

Functional Gene Expression Differences between Inbred Alcohol-Preferring (iP) and non-preferring (iNP) Rats

Project description:The objective of this study was to test the hypothesis that innate differences in gene expression in the brain could contribute to the differences in alcohol drinking or response to alcohol between adult male inbred alcohol-preferring (iP) and -non-preferring (iNP) rats. Gene expression was determined in the nucleus accumbens (ACB), amygdala (AMYG), frontal cortex (FC), caudate-putamen (CPU) and hippocampus (HIP) of alcohol-naïve adult male iP and iNP rats, using Affymetrix Rat Genome U34A microarrays (n = 6/strain). Significant differences between the two strains for each region were determined using Statistical Analysis of Microarrays (SAM). Using a false discovery rate threshold of 0.2, there were 46 genes with higher expression in iP rats and 61 genes with lower expression in the ACB, 111 genes with higher and 56 genes with lower expression in the AMYG, 61 genes with higher and 25 genes with lower expression in the FC, 39 genes with higher and 42 genes with lower expression in the CPU, and 35 genes with higher and 51 genes with lower expression in the HIP. In the AMYG, iP rats had higher expression of genes that are involved in neuronal growth and neurogenesis, e.g., brain derived neurotrophic factor, neuritin, etc. In contrast, in the ACB, iP rats had lower expression of genes involved in neurogenesis or cellular plasticity, e.g. cyclin E, vascular endothelial growth factor A. Many of the differences were in genes involved in intracellular signaling, cell membranes, extracellular matrix, and metabolism. These regional gene differences between the iP and iNP rat lines may contribute to the divergent alcohol drinking phenotypes of these rats.

Transcription profiling of rat brain tissue samples from cocaine-treated and saline-treated control animals

Project description:The 10 samples below represent a study where gene expression levels were measured in 5 different parts of the rat brain under cocaine-treated (GSM4696, GSM4698 - GSM4701) and saline-treated control (GSM4702 - GSM4706) conditions. The regions studied were amygdala (amy), caudate putamen (cpu), nucleus acumbens (na), prefrontal cortex (cpu), and the ventral tegmental area (vta). The data were analyzed using two different computational techniques, viz. singular value decomposition (SVD) and self-organizing maps (SOM), to identify a common set of genes that were regulated by cocaine administration.
