Study on the Analgesic and Compatibility Mechanism of Yuan-Hu Zhi Tong Prescription for Alleviating CCI-induced Neuropathic Pain

ABSTRACT: Neuropathic pain (NP) is a complex chronic pain due to the nervous system damage or diseases.Yuan-Hu Zhi Tong Prescription (YZP) is a well-known Traditional Chinese Medicine (TCM) formula for pain relief, which is composed of Corydalis Rhizoma (Yuanhu, YH) and Angelicae Dahuricae Radix (Baizhi, BZ). However, understanding of the analgesic and compatibility mechanisms of YZP remains limited. The present study found that YZP was more effective in relieving mechanical allodynia and thermal hypersensitivity than YH and BZ administered alone. To understand the potential analgesic and compatibility mechanisms of YZP on neuropathic pain (NP), RNA-seq and bioinformatics analyses were performed. The results revealed that YZP exerts analgesic effects mainly by relieving inflammation in the spinal cord through various mechanisms, such as suppressing leukocyte activation and cytokine-mediated signaling pathways. Moreover, YZP can relieve NP by modulating the neuropeptide signaling pathway and promoting damaged tissue regeneration. In terms of compatibility, YH and BZ demonstrated synergistic effects on the inflammatory response and neuropeptide signaling pathway. Furthermore, BZ was found to regulate calcium ion transport and promote skeletal muscle tissue regeneration, thereby alleviating concomitant symptoms of NP. Hub genes such as Ucn, Ptgs2, Gal, and others may play a pivotal role in YZP analgesia and the synergistic effects of YH-BZ compatibility.

Levo-tetrahydropalmatine Ameliorates Neuropathic Pain via Suppressing the Activation of the Clec7a-MAPK/NF-κB-NLRP3 Inflammasome Axis

Project description:Due to the complex pathogenesis of neuropathic pain (NP), the therapeutic effect of existing drugs on NP is not satisfactory, which seriously affects the life quality of patients. Accumulating studies have indicated that neuroinflammation in the spinal cord may play a vital role in NP development and progression. Levo-tetrahydropalmatine (l-THP) has been extensively used for the treatment of a variety of chronic pain for decades. However, the analgesic effects and the underlying mechanisms of I-THP against NP have not been fully elucidated. To address this problem, we herein carried out RNA-seq and bioinformatics analyses to identify the effective target profiling of I-THP including 1113 upregulated and 132 downregulated genes in spinal cord obtained from Chronic constrictive injury (CCI) rats with or without I-THP administration.

Arraystar lncRNA and mRNA array data for dorsal root ganglia neurons of mice

Project description:Nerve injury induces long-lasting pathological pain, namely neuropathic pain (NP), which is dysfunction of the whole pain transmission process, including dorsal root ganglia (DRG) in peripheral nerve system (PNS). Melatonin is well known over a long period of time as hormone of circadian rhythm closely related with the various aspects of pain conditions. Melatonin and melatonin related receptors (MTR1A and MTR1B) exerted amazing analgesic effect in many acute and chronic pain experimental studies, including electrically induced pain, thermally induced pain, mechanical induction of pain and chemical induction of pain. However, the anti-nociceptive action of melatonin in NP is still controversial and unclear. In the present study, our research firstly demonstrated the expression of melatonin receptors in the DRGs, and what more interesting is that MTR1A and MTR1B have a completely different cell type location (MTR1A in the satellite cells and MTR1B in the neurons). In order to get a basic glance at the effects of melatonin and MTR1B on the DRG neurons, a microarray analysis is applied to screen the pain related different expression genes in the primary DRGs cultured neurons with treatment of 1mM melatonin, 100μM MTR1B agonist 8-M-PDOT or vehicle (1% ethanol of normal saline). Subsequent examination was performed, and the finding suggested that melatonin suppressed neuropathic pain via MTR1B dependent and independent pathways in dorsal root ganglia neurons. And MTR1B in DRG may be a potential therapeutic target for NP.

Project description:Neuropathic Pain (NP) is a clinically common chronic refractory pain syndrome which threat to approximately 7–10% of the global population physical and mental health. However, the mechanism of metabolism alteration in NP remains unclear. This study is intended to figure out the relationship between the alternation of metabolism and the progression of NP.

Novel drug-like RAR-Beta agonist induces BRCA1 to prevent neuropathic pain

Project description:Neuropathic pain (NP) is associated with profound gene expression alterations within the nociceptive system. DNA mechanisms, such as epigenetic remodelling and repair pathways have been implicated in NP. Here we have used a rat model of peripheral nerve injury to study the effect of a novel RARβ-agonist, C286, currently under clinical research, in NP. A four week treatment initiated two days after the injury normalised pain sensation. Genome-wide and pathway enrichment analysis showed that multiple mechanisms persistently altered in the spinal cord were restored to preinjury levels by the agonist. Concomitant upregulation of DNA repair proteins, ATM and BRCA1, the latter being required for C286 mediated pain modulation, suggest that early DNA repair may be important to prevent phenotypic epigenetic imprints in NP. Thus, C286 is a promising drug candidate for neuropathic pain and DNA repair mechanisms may be useful therapeutic targets to explore.

RNA Expression Profiling of spinal cord tissues in a Rat Model of Neuropathic Pain

Project description:Neuropathic pain (NP), defined as a complex chronic pain state caused by somatosensory nervous system lesions or diseases, is currently the most challenging clinical neurological disorder in the world. The main signs and symptoms of NP include spontaneous pain, abnormal pain and hyperalgesia. It is generally believed that the specific pathological causes of NP include spinal cord or peripheral spinal cord injury, postherpetic neuralgia, trigeminal neuralgia, and tumor invasion. While the critical role of mRNA in NP is well recognized, the involvement of mRNA in the development of NP remains to be elucidated. Therefore, in this study, we explored changes in mRNA expression profiles through transcriptome sequencing to provide a landscape of mRNA dysregulation in the NP spinal cord.

Effective control of neuropathic pain by interrupting C/EBPβ-CLEC7A cross-talk-mediated NLRP3 inflammasome-dependent pyroptosis

Project description:Neuropathic pain (NP) is a complex chronic pain due to the nervous system damage or diseases.During NP development and progression, the neuroinflammation has been observed along the pain pathways from the spinal cord to the thalamus and the parietal cortex. It may be caused by the activation of glial cells, especially microglia, with production of cytokines and other inflammatory mediators within the central nervous system (CNS), especially in spinal cord. In this study, we used microarrays to detect the global gene expression in spinal cord of rats in sham group and CCI model group(an animal model of neuropathic pain), and the differentially expressed genes between diseases and control group were obtained.
