Identification of activity-induced genes in cortical inhibitory neurons (RNA-Seq)

ABSTRACT: To identify the activity-induced gene expression programs in inhibitory neurons, we analyzed RNA extracted from cultured E14 mouse MGE-derived neurons (DIV 10) after these cultures were membrane-depolarized for 0, 1 and 6 hrs with 55mM extracellular KCl.

Identification of activity-induced genes in cortical inhibitory neurons (RNA-Seq)

Project description:To identify the activity-induced gene expression programs in inhibitory neurons, we analyzed RNA extracted from cultured E14 mouse MGE-derived neurons (DIV 10) after these cultures were membrane-depolarized for 0, 1 and 6 hrs with 55mM extracellular KCl. Mouse E14 MGE-derived neurons 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 WT RNA-Seq was performed on ABi SOLiD

Identification of activity-induced Npas4-regulated genes in cortical inhibitory and excitatory neurons (array)

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.

Genome-wide activity-dependent MeCP2 phosphorylation regulates nervous system development and function [cultured cortical neurons]

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.

Transcription profiling of mouse KCl depolarization-regulated genes in cortical neurons

Project description:we used DNA microarray analysis to identify genes that are induced by neuronal activity in excitatory neurons at the time when inhibitory synapses are forming and maturing on them. Experiment Overall Design: We cultured cortical neurons for 7 DIV until the process of inhibitory synapse development was underway, and then depolarized the neurons with 50 mM of KCl to activate L-type voltage-sensitive calcium channels (L-VSCCs) for 0, 1 or 6 hours, the cells were lysed, mRNA isolated and hybridized to Affymetrix arrays. Data were collected from 3 independent experiments.

RNAi profiling of mouse hippocampal neurons infected with lentivirus expressing Npas4-RNAi or control-RNAi to study Npas4-regulated genes

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.
