P2X7 Receptor-Induced Bone Cancer Pain by Regulating Microglial Activity via NLRP3/IL-1beta Signaling
CONCLUSION: These findings suggest that targeting the microglial P2X7R activated NLRP3/IL-1beta signaling pathway could serve as a potential strategy for BCP treatment.PMID:36375190

CAV-1 Overexpression Exacerbates the Manifestation in EPAC-1-Induced Chronic Postsurgical Pain in Rats
CONCLUSION: CAV-1 mediates the functional coupling of microglia, astrocytes, and neurons, and thus EPAC-1/CAV-1 plays an important role in CPSP exacerbation.PMID:35958678 | PMC:PMC9357801 | DOI:10.1155/2022/8566840

Activation of Double-Stranded RNA –Activated Protein Kinase in the Dorsal Root Ganglia and Spinal Dorsal Horn Regulates Neuropathic Pain Following Peripheral Nerve Injury in Rats
AbstractDouble-stranded RNA (dsRNA) –activated kinase (PKR) is an important component in inflammation and immune dysfunction. However, the role of PKR in neuropathic pain remains unclear. Here, we showed that lumbar 5 spinal nerve ligation (SNL) led to a significant increase in the level of phosphorylated PKR (p-PKR) in both the dor sal root ganglia (DRG) and spinal dorsal horn. Images of double immunofluorescence staining revealed that p-PKR was expressed in myelinated A-fibers, unmyelinated C-fibers, and satellite glial cells in the DRG. In the dorsal horn, p-PKR was located in neuronal cells, astrocytes, and microglia...

SUMOylation of Kir7.1 participates in neuropathic pain through regulating its membrane expression in spinal cord neurons
CONCLUSION: SUMOylation of the Kir7.1 in the spinal cord might contribute to the development of SNI-induced mechanical allodynia by decreasing the Kir7.1 surface expression in rats.PMID:35633059 | DOI:10.1111/cns.13871

Grem1 accelerates nucleus pulposus cell apoptosis and intervertebral disc degeneration by inhibiting TGF- β-mediated Smad2/3 phosphorylation
This study aimed to investigate the mechanisms of Grem1 in the degenerative process of intervertebral discs. Dysregulated genes were determined by analyzing microarray profiles. The expression of Grem1 in 17 human disc samples (male:female = 9:8) and rat models (n = 5 each group) was measured by western blotting (WB), real-time quantitative PCR (RT-qPCR), and immunohistochemistry (IHC). The regulatory effects of Grem1 on apoptosis were examined using siRNAs, flow cytometry, immunofluorescence (IF), and WB. The therapeutic effect was evaluated by locally injecting specific Grem1 siRNA into IVDD rats. The expression of Grem1...

Metformin Relieves Bortezomib-Induced Neuropathic Pain by Regulating AMPKa2-Mediated Autophagy in the Spinal Dorsal Horn
Neurochem Res. 2022 Mar 12. doi: 10.1007/s11064-022-03571-7. Online ahead of print.ABSTRACTChemotherapy-induced neuropathic pain is a major clinical problem with limited treatment options. Here, we show that metformin relieves bortezomib (BTZ)-evoked induction and maintenance of neuropathic pain by preventing the reduction in the expression of Beclin-1, an autophagy marker, in the spinal dorsal horn. Application of rapamycin or 3-methyladenine, autophagy inducer and inhibitor, respectively, affected the mechanical allodynia differently. Co-application of 3-methyladenine and metformin partially inhibited the effect of metfo...
