NGF is a secreted molecular signal synthesized by neuronal target tissues.  In developing nociceptors, NGF engages the receptor tyrosine kinase TrkA to activate a gene transcriptional program involving the regulation of hundreds of transcripts.  To identify NGF-dependent genes in developing mouse nociceptors, we have designed and performed two separate microarray screens to compare gene expression profiles of DRG neurons either with or lacking NGF signaling. For the first screen comparing DRGs of Bax\u2212/\u2212 and Ngf\u2212/\u2212; Bax\u2212/\u2212 mice, DRGs were dissected and pooled from E14.5 Ngf\u2212/\u2212; Bax\u2212/\u2212 and Bax\u2212/\u2212 embryos.  Total RNA was extracted and directly subjected to microarray analysis.  For the second screen comparing mouse DRG explants grown in the presence or absence of NGF, E13.5 mouse DRG explants were cultured for two days with 50 ng/ml of either NGF or NT3.  Total RNA was extracted and then subjected to microarray analysis.", "source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-25611", "sample_source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-25611/samples/"}
