Mouse DRG RNA-Seq

ABSTRACT: Multiple myeloma (MM) is a neoplasia of B plasma cells that often induces bone pain. However, the mechanisms underlying myeloma-induced bone (MIBP) pain are mostly unknown. Using a localized MM mouse model, we investigated MM induced gene expression changes in the dorsal root ganglia (DRG) innervating the MM-bearing bone and found alterations in pathways associated with cell cycle, immune response and neuronal signalling. The MM transcriptional signature was consistent with metastatic MM infiltration to the DRG, a never-before described feature of the disease that we further demonstrated histologically. In the DRG, MM cells caused loss of vascularization and neuronal injury, which may contribute to late-stage MIBP.

scRNA-sequencing reveals subtype-specific transcriptomic perturbations in DRG neurons of PirtEGFPf mice in neuropathic pain condition

Project description:Functionally distinct subtypes/clusters of dorsal root ganglion (DRG) neurons may play different roles in nerve regeneration and pain. However, details about their transcriptomic changes under neuropathic pain conditions remain unclear. Chronic constriction injury (CCI) of the sciatic nerve represents a well-established model of neuropathic pain, and we conducted single-cell RNA-sequencing (scRNA-seq) to characterize subtype-specific perturbations of transcriptomes in lumbar DRG neurons on day 7 post-CCI. By using PirtEGFPf mice that selectively express an enhanced green fluorescent protein in DRG neurons, we established a highly efficient purification process to enrich neurons for scRNA-seq. We observed the emergence of four prominent CCI-induced clusters and a loss of marker genes in injured neurons. Importantly, a portion of injured neurons from several clusters were spared from injury-induced identity loss, suggesting subtype-specific transcriptomic changes in injured neurons. Moreover, uninjured neurons, which are necessary for mediating the evoked pain, also demonstrated cell-type-specific transcriptomic perturbations in these clusters, but not in others. Notably, male and female mice showed differential transcriptomic changes in multiple neuronal clusters after CCI, suggesting transcriptomic sexual dimorphism in DRG neurons after nerve injury. Using Fgf3 as a proof-of-principle, RNAscope study provided further evidence of increased Fgf3 in injured neurons after CCI, supporting scRNA-seq analysis, and calcium imaging study unraveled a functional role of Fgf3 in neuronal excitability. These findings may contribute to the identification of new target genes and the development of DRG neuron cell-type-specific therapies for optimizing neuropathic pain treatment and nerve regeneration.

Mouse DRG incision injury versus sham_DIA-MS

Project description:Acute pain after surgery is still managed insufficiently. One major need is, therefore, the identification of new targets specifically relevant for postoperative pain to develop effective and non-addictive analgesics. To this end, we have used the plantar incision model in male mice and DIA-MS to reveal unprecedented insights into proteome dynamics in dorsal root ganglia (DRG) 24 hours after incision.

Proteomics on Nav1.8-positive nociceptors of mouse DRG

Project description:Nociceptors play an essential role in both acute pain and chronic pain conditions. In this study, we examined the proteome of mouse dorsal root ganglia and compared NaV1.8Cre+/-; ROSA26-flox-stop-flox-DTA (Diphtheria toxin fragment A) mutant mice (NaV1.8Cre-DTA), in which NaV1.8-positive neurons (mainly nociceptors) in dorsal root ganglia (DRG) were ablated, with respective littermate wildtype controls.

Differentially expressed long non-coding RNAs and mRNAs in DRG of bone cancer pain and sham group rats based on microarray and bioinformatic analysis

Project description:Objective: The diagnostic roles of long non-coding RNAs (lncRNAs) and mRNAs in bone cancer pain are still not well defined. We aimed to identify differentially expressed DRG mRNAs in bone cancer pain and sham group rats systematically. Methods: Expression profile of mRNAs in DRG from bone cancer pain and sham group rats was analyzed by microarray assay. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway based approaches were used to investigate biological functions and signaling pathways affected by the differentially expressed mRNAs. GPR160 was selected for validation using Real-Time PCR. Results: Compared with sham group, a total of 807 differentially expressed mRNAs were revealed by heatmap and volcano-plot, including up-regulation in 720 and down-regulation in 87 (fold change ≥ 2 and P < 0.05), respectively. Pathways analysis based on upregulated mRNAs were mainly involved in antigen processing and presentation and phagosome pathway (P < 0.05). We first reported differentially expressed mRNAs in bone cancer pain and sham group rats systemically. Combined with the published dataset, we identified several differentially expressed mRNAs which might to be diagnostic or prognostic markers. The biological functions of those mRNAs should be further validated. Taken together, this study provided the basis for future treatment of bone cancer pain.

Project description:The present study is aimed to analyze the transcriptomic changes across the generation and development of cancer induced bone pain (CIBP) in primary afferent neuron, which would provide a comprehensive understanding of the molecular mechanisms of CIBP. The transcriptomic profiles of primary afferent neuron in DRG from different time points were examined by RNAseq technique, including gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. Our study provide the first detailed analysis of DRG transcriptomes during the generation and development of CIBP.

Anthrax toxins regulate pain signaling and can deliver molecular cargoes to Antxr2+ DRG sensory neurons

Project description:We found that intrathecal injection of anthrax edema toxin (ET), causes analgesia in adult B6J mice. In order to determine if DRG neuron transcriptional responses play a role in pain blockade, we performed a bulk RNA-seq experiment on dissected mouse DRG neurons. We report that anthrax edema toxin causes transcriptional responses in DRG neurons 2h after in vivo administration

The Nociceptive Activity of Peripheral Sensory Neurons is Modulated by the Neuronal Membrane Proteasome

Project description:Proteasomes are critical for peripheral nervous system (PNS) function. Here, we investigate mammalian PNS proteasomes and reveal the presence of the neuronal membrane proteasome (NMP). We show that specific inhibition of the NMP on distal nerve fibers innervating the mouse hind paw leads to reduction in mechanical and pain sensitivity. Investigating PNS NMPs we demonstrate their presence on the somata, proximal, and distal axons of a subset of dorsal root ganglion (DRG) neurons. Single-cell RNA sequencing experiments reveal that the NMP expressing DRGs are primarily MrgprA3+ and Cysltr2+. NMP inhibition in DRG cultures leads to cell autonomous and non-cell autonomous changes in Ca2+ signaling induced by KCl depolarization, ab-meATP, or the pruritogen histamine. Taken together, these data support a model whereby NMPs are expressed on a subset of somatosensory DRGs to modulate signaling between neurons of distinct sensory modalities and indicate the NMP as a potential target for controlling pain

A transcriptome data set for comparing skin, muscle and DRG between acute and chronic postsurgical pain rats.

Project description:Chronic postsurgical pain (CPSP), with a high prevalence and rising epidemic of opioids crisis, is typically derived from acute postoperative pain. Revealing the peripheral mechanisms behind the transition from acute to chronic pain after surgery is necessary. We established on two recognized animal models, the Lateral Paw Incision (LPI) model and the Skin/Muscle Incision and Retraction (SMIR) model, in simulation of acute and chronic postsurgical pain. The tissue of incisional skin, muscle and DRG at several time points are harvested and send for next-generation RNA sequencing (RNA-seq). Then the quality of sequencing results is validated. Our data could explain the time-course transcriptomic variation in the tissue of skin, muscle and DRG, and further to identify the potential origin and mechanism of CPSP.
