Project description:Gene expression profiling was performed to identify Siah2-dependent changes in cells subjected to ER stress, hypoxia, and combined glucose/oxygen deprivation. To establish the magnitude of the Siah2 effect on the ER stress response, we have compared gene expression profiles of WT and Siah1a-/-::Siah2-/- mouse embryo fibroblasts (MEFs) that were subjected to glycosylation inhibitor tunicamycin (TM), thapsigargin (TG), glucose deprivation, or glucose/oxygen deprivation. Overall, this analysis confirmed changes associated with ER stress that had not previously been associated with Siah2 signaling, substantiating Siah2 as a key coordinator of ER stress through the ATF4 and sXbp1 pathways. WT and Siah1a/Siah2 KO MEF cells were treated with TM or TG for 6 h, or subjected for 12 h to oxygen deprivation, glucose deprivation or a combination of oxygen and glucose deprivation, in duplicate.
Project description:Migroglia cells were exposed to oxygen-glucose deprivation (OGD) for 3 h. The miRNA was isolated and the expression profiles of OGD-activated cells were compared with the profiles of resting cells.

Project description:To investigate the the expression profile and potential pathways involved in celluar ischemic stroke model, we established murine HT22 cell lines with oxygen-glucose deprivation/reoxygenation (OGD/R) in vitro
Project description:The goal of this study are to compare the transcriptome profiling (RNA-seq) of rat bone marrow mesenchymal stem cells (BMSC) transcriptome profiling (RNA-seq) under the condition of infection of different lentiviruses(shRac1 or shLuci) and/or oxygen-glucose deprivation (OGD).
Project description:Migroglia cells were exposed to oxygen-glucose deprivation (OGD) for 3 h. The miRNA was isolated and the expression profiles of OGD-activated cells were compared with the profiles of resting cells. Two samples were analysed. miRNAs that were differentially expressed (increased or decreased in expression by â¥1.5-fold) between theOGD-activated and resting cells were identified.
Project description:To detect miRNAs in oxygen and glucose deprivation (OGD) conditions we cultured cortical neurons Embryonic day 15 and subjected them to OGD We performed differentially expression analysis of miRNA-seq of wild-type and ciRS-7 KO neurons
