Project description:RNA extracted from human frontal cortex area 8, the main area afected in FTLD, of controls (n=10), sporadic FTLD-TDP (sFTLD) (n=10) and C9ORF72-familial FTLD (fFTLD) (n=10) samples were analyzed using the Affymetrix Clariom™ D Assay, human (Affymetrix ref.902923). The present study identifies the main gene deregulation between sporadic forms of FTLD-TDP (sFTLD) and the major and most common genetic cause of FTLD, the C9ORF72 repeat expansion (fFTLD), when compare with control samples.
Project description:We used Affymetrix miRNA arrays to analyze the expression of miRNAs in the frontal cortex and hippocampus of 8-week-old C57BL/6J wt mice. We compared these microarray-based expression profiles to ones obtained by miRNA sequencing from the same brain regions of the same mouse strain. miRNA expression profiling of frontal cortex and hippocampus from C57BL/6J mice (N=3) was performed with Affymetrix miRNA array
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.
Project description:The inbred LOU/C/Jall rat is currently described as a model of successful aging. These rats have a longer healthy median lifespan than other strains, do not develop obesity, diabetes, or tumor and more importantly they do not show cognitive decline with aging. This is the first study to examine gene expression changes in the inbred LOU/C/Jall rat hippocampus and frontal cortex. Microarray data from LOU/C/Jall rats aged of 5 months were compared to the one measured in rats aged of 26 month. We have identified a set of 15 genes in the hippocampus and 70 genes in the frontal cortex that could be grouped into several clusters of similar expression profiles and that are involved in biological functions, namely regulation of plasticity, inflammatory response, metabolic, catabolic and homeostatic processes, and transcription. Genes were mainly up-regulated in aged brain. Gene expression profil in hippocampus and cortex frontal of LOU/C/Jall rats strain. Rats were 3 and 26 months old.
Project description:Here we used mass spectrometry-based proteomics technology to explore SEPs with potential function in five brain regions of the mouse. SEPs with unique peptides were identified in hippocampus, frontal cortex, temporal cortex, occipital cortex and parietal cortex.
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.
Project description:Survey of gene expression in ten common inbred strains of laboratory mouse. Seven brain regions examined: amygdala, basal ganglia, cerebellum, frontal cortex, hippocampus, cingulate cortex, olfactory bulb. Experiment Overall Design: Tissue from three animals was pooled on each array. Three biological replicates per strainxregion condition. Animals were 4-5 weeks of age.
Project description:Inbred mouse strains differ in their innate anxiety levels. We used RNA-sequencing to identify gene expression differences in hippocampus and frontal cortex of six mouse strains.
Project description:In order to elucidate the molecular mechanisms of action of Phenytoin, we examined by microarrays the effects of prolonged administration of Phenytoin on gene expression in hippocampus and frontal cortex of Sprague-Dawley rats chronically treated with Phenytoin.
