Project description:This SuperSeries is composed of the following subset Series:; GSE11256: KCl depolarization-regulated genes in mouse cortical neurons; GSE11258: Npas4-regulated genes in mouse hippocampal neurons Experiment Overall Design: Refer to individual Series
Project description:5’ ExoSeq of total RNA (rRNA & signal recognition particle RNA depleted) from mouse cortical neurons before and after membrane depolarization by potassium chloride (KCl).
Project description:Activation of neurons is one of the fundamental events for the functioning of nervous system. Neuronal activation relays information to next neurons. On the other hand, the activated neurons themselves are also influenced by neuronal activation. Depending on the type and condition of neuronal activation, these activated neurons change their gene expressions, thereby being able to process information more or less efficiently. We applied the microarray technology to identify hither-to-uncharacterized as activity-dependent genes. Especially, we screened the transcription factors, because early changes in the transcription factors should result in alterations of gene expression profiles and subsequent neuronal properties. Experiment Overall Design: Rat primary cortical neurons with or without KCl treatment were selected for RNA extraction and hybridization on Affymetrix microarrays. To identify the genes whose expression was induced by depolarization, we first compared gene expression profiles in control vs. 4 hr after KCl (25 mM) treated cortical neurons using Affymetrix Genechips specified for neurobiology. All four hybridizations were analyzed for correlation accuracy between the replicates of the same treatments .Control replicates (control 1, 2) KCl-treated replicates (KCl 1, 2)
Project description:RNA-seq of total RNA from Rad21lox/lox;NexCre/+ and Rad21+/+;NexCre/+ dissociated cortical neurons at Day In Vitro (DIV10) without stimulation or after treatment with TTX/D-AP5 and 1h or 6h of KCl depolarization.
Project description:5C-seq from Rad21lox/lox;NexCre/+ and Rad21+/+;NexCre/+ dissociated cortical neurons at Day In Vitro (DIV10) without stimulation or after treatment with TTX/D-AP5 and 1h of KCl depolarization. And, 5C of and doxycycline treated Rad21-TEV primary neurons transduced with NLS-TEV
Project description:To examine potential differences in activity-dependent gene expression, we analyzed mRNA expression in cultured neurons isolated from Wild-type vs MeCP2 S421A mice at 0 (unstimulated), 1 or 6 hours after membrane depolarization by exposure to high extracellular KCl (55mM) All mice were male littermates from one of three litters. We isolated RNA from dissociated cortical cultures (E16+7DIV) isolated from Wild-Type or MeCP2 S421A knock-in mice littermates. Cells were either left unstimulated or depolarized for 1 or 6 hours by addition of 55mM KCl to the media. mRNA expression was analyzed using the Affymetrix GeneChip Mouse Expression Set 430 2.0 microarray platform.
