Project description:Neuronal cultures were treated with candesartan at neuroprotective concentrations followed by excitotoxic glutamate amounts. Candesartan significantly reduced glutamate-induced inflammation. To provide mechanistic insight into the potential targets and pathways that may underlie these benefits, we performed genome wide expression profile analysis and evaluated the data by Ingenuity Pathway Analysis (IPA) and Gene Set Enrichment Analysis (GSEA). We found that the inflammation signal transduction pathways were major components of the neuronal response to glutamate excitotoxicity, and that candesartan significantly ameliorated glutamate-induced alterations in gene expression. Further analysis showed significant associations of these genes with two independent published networks identified by microarray analysis of hippocampal samples obtained post-mortem from brains of patients diagnosed with AD . 8 days old rat Primary cerebellar granule cells (CGCs) were treated with DMSO, Glutamate, Candesartan or Glutamate +candesartan. Four replicates of each treatment were done.
Project description:Expression analysis was performed with in vitro cultured cerebellar granule neurons (CGNs) isolated from rat brain. The CGNs were culture for four weeks. Each sample was collected after interval of seven days. No treatment was given to any cultured neurons at any time point. The purpose of the experiment was to identify the genes differentially expressed during the senescence of CGNs. The experiment is useful in revealing the senescence associated genetic markers in neurons.
Project description:In order to establish a rat embryonic stem cell transcriptome, mRNA from rESC cell line DAc8, the first male germline competent rat ESC line to be described and the first to be used to generate a knockout rat model was characterized using RNA sequencing (RNA-seq) analysis.
Project description:Analysis of LBNF1 rat testes from controls, containing both somatic and all germ cell types and from irradiated rats in which all cells germ cells except type A spermatgogonia are eliminated. Results provide insight into distinguishing germ and somatic cell genes and identification of somatic cell genes that are upregulated after irradiation.
