ABSTRACT: Genome-wide RNA expression analysis of rat dorsal root ganglion tissue after local absorbable collagen sponge implantation and BMP-2 exposure
Project description:Analysis of whole dorsal root ganglion tissue expression signatures in responses to absorbable collagen sponge implantation with and without BMP-2 exposure. The hypothesis is that inflammatory macrophage-associated responses to ACS implantation contributes to nociception in the DRG and spinal nerve.
Project description:We conducted RNA-sequencing of lidocaine hydrochloride in treating rat dorsal root ganglion neurons to detect lidocaine’s effect of transcriptome profiling changes compared with control.
Project description:Primary isolated rat dorsal root ganglion nerve cells (DRGs) were cultured with high glucose in vitro and divided into normal culture group and high glucose culture group
Project description:Inflammation plays a role in neuropathic pain conditions as well as in pain induced solely by an inflammatory stimulus. Robust mechanical hyperalgesia and allodynia can be induced by locally inflaming the L5 dorsal root ganglion (DRG) in rat. This model allows investigation of the contribution of inflammation per se to chronic pain conditions. Most previous microarray studies of DRG gene expression have investigated neuropathic pain models involving axon transection. To examine the role of inflammation, we used microarray methods to examine gene expression 3 days after local inflammation of the L5 DRG in rat. We observed significant regulation in a large number of genes (23% of observed transcripts), and examined 221 (3%) with a fold-change of 1.5-fold or more in more detail. Immune-related genes were the largest category in this group and included members of the complement system as well as several pro-inflammatory cytokines. However, these upregulated cytokines had no prior links to peripheral pain in the literature other than through microarray studies, though most had previously described roles in CNS (especially neuroinflammatory conditions) as well as in immune responses. The L5 dorsal root ganglion (DRG) was locally inflamed with zymosan/Incomplete Freund's Adjuvant. DRG were isolated 3 days later. Each sample was RNA extracted from a single DRG. 6 samples from rats with local DRG inflammation were compared with 6 samples from sham-operated rats.
Project description:We use dorsal root ganglion tissues of WT SD rats, or imiquimod(IMQ)-induced psoraisis-like rat model treated with or without epidural injection of 1% lidocaine. We isolated total RNA for RNA-sequencing.
Project description:We used microarray-based expression genomics in 25 inbred mouse strains to identify dorsal root ganglion (DRG)-expressed genetic contributors to mechanical allodynia a prominent symptom of chronic pain. Expression genetics identifies a role for the Chrna6 (alpha 6-nicotinic receptor) gene in pain in mice and humans. Dorsal root ganglion tissue across multiple inbred mouse strains, both male and female
Project description:We performed a data independent acquisition (DIA) -based quantitative proteomics strategy to investigate the global proteome alteration in the dorsal root ganglion (DRG) tissues from mice injected with oxaliplatin for different periods.
Project description:Painful diabetic peripheral neuropathy (PDPN) is a common complication of diabetes mellitus (DM). As one of the most disturbing symptoms, mechanical allodynia (MA) in PDPN remains largely unexplored. This dataset contains single-cell RNA sequencing results from rat dorsal root ganglion (DRG). The goal of this experiment was to investigate the transcriptional changes of distinct cell types in the DRG along MA development.
