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:We performed a DNA microarray experiment to identify activity-regulated genes that are misregulated in the absence of Npas4. Experiment Overall Design: We infected mouse hippocampal neurons with lentivirus expressing Npas4-RNAi or control-RNAi @ 3 DIV and depolarized the neurons @ 8 DIV with 50 mM of KCl for 0, 1, 3 or 6 hours. Neurons were lysed, mRNA isolated and hybridized to Affymetrix arrays. Data were collected from 3 independent experiments.
Project description:RNAi profiling of mouse hippocampal neurons infected with lentivirus expressing Npas4-RNAi or control-RNAi to study Npas4-regulated genes
Project description:To identify the activity-induced gene expression programs in inhibitory and excitatory neurons, we analyzed RNA extracted from cultured E14 mouse MGE- and CTX-derived neurons (DIV 10) after these cultures were membrane-depolarized for 0, 1 and 6 hrs with 55mM extracellular KCl. To identify the gene programs regulated in these cells by the activity-induced early-response transcription factor Npas4, we repeated the same experiment in the MGE- and CTX-cultures lacking Npas4 (Npas4-KO). Littermate mouse E14 MGE- or CTX-derived neurons (WT or KO for Npas4) were cultured for 9 days, quieted overnight with TTX and AP-5 and then membrane-depolarized for 0, 1 or 6 hours by raising the extracellular KCl-concentration to 55mM. RNA was then extracted and analyzed using Affymetrix GeneChip Mouse Expression Set 430 2.0 microarray platform.
