Expression data from FACS purified nociceptor neurons from peripheral sensory ganglia

Project description:The goal of this study was to analyze global gene expression in specific populations of nociceptor sensory neurons, the neurons that detect damaging/noxious stimuli. The dorsal root ganglia (DRG), trigeminal ganglia, and nodose ganglia are anatomically distinct peripheral sensory ganglia that contain nociceptors which innervate skin, gut, lungs, and other distinct organ tissues. We used flow cytometry to purify nociceptors from these ganglia and profiled their global gene expression signatures to compare gene expression between these different anatomically distinct nociceptors. Nav1.8-Cre were bred with Rosa26-TdTomato to generate Nav1.8-Cre/R26-TdTomato reporter progeny, where all peripheral nociceptor neurons are genetically marked with red fluroescence due to specific expression of the TTX- resistant sodium channel Nav1.8. Lumbar region dorsal root ganglia (DRG), trigeminal ganglia, and nodose ganglia were dissected from mice (3 mice were pooled/sample). Highly red fluorescent neurons were Facs purified, RNA extracted, and processed for microarray analysis.

DREAM in pain mechanisms in the trigeminal ganglia

Project description:Expression of DREAM in dorsal root ganglia and spinal cord is related to endogenous control mechanisms of acute and chronic pain. In primary sensory trigeminal neurons high levels of endogenous DREAM protein are preferentially localized in the nucleus, suggesting a major transcriptional role. Here, we show that DREAM participates in the control of trigeminal pain perception through the regulation of prodynorphin and BDNF. Furthermore, genome-wide analysis of trigeminal neurons in daDREAM transgenic mice revealed that cathepsin L (CTSL) and the monoglyceride lipase (MGLL) are new DREAM downstream targets and have a role in the regulation of trigeminal nociception.

Npr2-mediated cGMP signalling modulates S-palmitoylation and controls growth cone morphology of DRG neurons

Project description:A cGMP signalling cascade composed of the ligand C-type natriuretic peptide (CNP), the natriuretic peptide receptor 2 (Npr2) and the cGMP-dependent kinase Iα (cGKI) is implicated by growth cone splitting in the bifurcation of afferents from dorsal root ganglia (DRG), cranial sensory ganglia (CSG) and mesencephalic trigeminal neurons (MTN). To get further mechanistic insights into the process of axon bifurcation we applied different cell culture approaches to decipher downstream activities of cGKI in somatosensory growth cones. We demonstrate that CNP induces an enlargement of DRG growth cones via cGKI which can be blocked or stimulated by pharmacological reagents that interfere with S-palmitoylation. cGKI colocalizes primarily in the central domain of the growth cone with the palmitoylome and vesicular structures including the endoplasmic reticulum, early endosomes, lysosomes and in the soma in the Golgi apparatus. Consistently, an acyl-biotin-exchange chemistry-based screen indicated that cGMP signalling regulates S-palmitoylation of a restricted pool of proteins in the DRG-derived cell line F11.

Transcription profiling of mouse spinal and trigeminal sensory ganglia of Brn3a knockout and wild type mice reveals conserved and distinct regulatory targets of Brn3a at different levels of the sensory axis

Project description:General somatic sensation is conveyed to the central nervous system at cranial levels by the trigeminal ganglion (TG), and at spinal levels by the dorsal root ganglia (DRG). Although these ganglia have similar functions, they have distinct embryological origins, in that both contain neurons originating from the neural crest, while only the TG includes cells derived from the placodal ectoderm. Here we use microarray analysis of E13.5 embryos to demonstrate that the developing DRG and TG have very similar overall patterns of gene expression. In mice lacking the POU-domain transcription factor Brn3a the DRG and TG exhibit many common changes in downstream gene expression, but a subset of genes show increased expression only at cranial levels. Although silent in wild-type ganglia, the promoter regions of genes which are activated in the absence of Brn3a also exhibit increased histone H3-acetylation at levels similar to constitutively transcribed gene loci, and this H3-acetylation is tissue-specific for genes which are increased only in the TG. These results demonstrate that one developmental role of Brn3a is to repress potential differences in gene expression between sensory neurons generated at different axial levels, and to regulate a convergent program of developmental gene expression, in which functionally similar populations of neurons are generated from different embryological substrates. Experiment Overall Design: Microarrays used to compare the patterns of gene expression in the dorsal root ganglia and trigeminal ganglia of Brn3a knockout and wild-type mice. Embryonic day 13.5 (E13.5) was chosen because at this point in development mutant mice exhibit major defects in sensory axon growth, but have yet to undergo the period of extensive sensory neuron death associated with later stages.

Transcription profiling of trigeminal ganglia of Brn3a knockout and wild type mice to determine the regulatory targets of transcription factor Brn3a.

Project description:Mice lacking the POU-domain transcription factor Brn3a exhibit marked defects in sensory axon growth and abnormal sensory apoptosis. We have determined the regulatory targets of Brn3a in the developing trigeminal ganglion using microarray analysis of Brn3a mutant mice. These results show that Brn3 mediates the coordinated expression of neurotransmitter systems, ion channels, structural components of axons and inter- and intracellular signaling systems. Loss of Brn3a also results in the ectopic expression of transcription factors normally detected in earlier developmental stages and in other areas of the nervous system. Target gene expression is normal in heterozygous mice, consistent with prior work showing that autoregulation by Brn3a results in gene dosage compensation. Detailed examination of the expression of several of these downstream genes reveals that the regulatory role of Brn3a in the trigeminal ganglion appears to be conserved in more posterior sensory ganglia but not in the CNS neurons that express this factor. Experiment Overall Design: Microarrays used to compare the patterns of gene expression in the trigeminal ganglia of Brn3a knockout and wild-type mice. Embryonic day 13.5 (E13.5) was chosen because at this point in development mutant mice exhibit major defects in sensory axon growth, but have yet to undergo the period of extensive sensory neuron death associated with later stages.
