Project description:Sensory neurons of the dorsal root ganglion (DRG) play a crucial role in maintaining tissue homeostasis by sensing and initiating responses to stimuli. While most preclinical studies of DRGs are conducted in rodents, much less is known about the mechanisms of sensory perception in primates. We generated a transcriptome atlas for mouse, guinea pig, cynomolgus monkey, and human DRGs using a framework that implements a common laboratory workflow (i.e sequencing technologies, laboratory protocols, and sample archival methods) and multiple data-integration approaches to generate accurate cross-species mappings of sensory neuron subtypes.

Project description:Although DNA methylation plays a critical role in the development and function of mammalian central nervous system (CNS), its role in peripheral neurons has not been elucidated. To address this issue, we produced conditional knockout mice (CKO) specifically deleting the gene for maintenance DNA methyltransferase 1 (Dnmt1) during the development of neural crest cells. Despite global hypomethylation in the embryonic dorsal root ganglion (DRG) of the CKO mice, the number of sensory neurons was relatively unaffected. However, expression of many genes required for sensory neuron development was altered in embryonic mutant DRG, including down-regulation of Runx1 and TrkA genes as well as up-regulation of Id1 and Dtx1, two negative regulators for neurogenesis. Accompanied with the downregulation of an NGF receptor TrkA, the peripheral axonal projection and the branching of sensory neurons were impaired. Furthermore, the expression of the neuropeptide Galanin and several vanilloid receptors such as TrpV1 and TrpM8 were not detected in the DRG of the CKO mice during late embryonic and neonatal stages, suggesting that DNA methylation regulates the differentiation program for a subset of nociceptive sensory neurons. Taken together, our findings suggest that through transcriptional regulation of key developmental genes in sensory neurons, DNA methylation play a key role in the control of the axonal projection and fate specification of peripheral sensory neurons. We compared gene expression patterns in Wildtype and DNA methylation deficient (Wnt1-cre; Dnmt1 mutant) mouse dorsal cortex. We performed 4 replicates using different each individual mouse strain. The Sample GSM565172 table is the average log ratio for the 4 replicatesArrays were performed.

Project description:Calpains are non-lysosomal, Ca2+-dependent cysteine proteases, which are associated with various cellular functions but have so far been mainly studied in the context of disease. Their contribution to homeostasis in the healthy organism is still not well understood and their substrates have remained enigmatic in most cases. In the present study, we describe a previously unrecognized role for the calpain protease calpain2 in the regulation of neuronal differentiation of adult neural stem- and progenitor cells through cleavage and elimintation of the neuronal fate determinant MEIS2. Mass spectrometry analysis was performed on immunoprecipitated MEIS2 protein to identify phosphory¬lated residues in MEIS2 and on immunoprecipitated MEIS2 incubated with native porcine calpain2 to map calpain2-induced cleavage sites in the protein.

Project description:Aim: Dorsal root ganglion neuron-derived immortal cell lines including ND7/23 and F-11 cells have been used extensively as in vitro model systems of native peripheral sensory neurons. However, while it is clear that some sensory neuron-specific receptors and ion channels are present in these cell lines, a systematic comparison of the molecular targets expressed by these cell lines with intact peripheral neurons is lacking. Methods: we examined the expression of RNA transcripts in the human neuroblastoma-derived cell line, SH-SY5Y, and two dorsal root ganglion hybridoma cell lines, F-11 and ND7/23, using Illumina next-generation sequencing. Results: The expression profile of these three cell lines did not resemble any specific dorsal root ganglion neuron subclass. The cell lines lacked many markers for nociceptive sensory neurons, such as the transient receptor potential V1 gene, but expressed markers for both myelinated and unmyelinated neurons. Conclusion: This paper provides insights into the receptor repertoire expressed in common dorsal root ganglion neuron-derived cell lines, and illustrates the limits and potentials of these cell lines as tools for neuropharmacological exploration.

Project description:In order to establish a consensus catalog of dorsal rott ganglion cell types, we used comprehensive transcriptome analysis of single cells for unsupervised identification and molecular classification of sensory neurons independent of any a priori knowledge of sensory subtypes. RNA-Seq was performed on 799 dissociated single cells dissected from the mouse lumbar dorsal root ganglion distributed over a total of nine 96-well plates
