Reduction of SIRT1-Mediated Epigenetic Upregulation of Nav1.7 Contributes to Oxaliplatin-Induced Neuropathic Pain
CONCLUSIONS: These findings suggest that reduction of SIRT1-mediated epigenetic upregulation of Nav1.7 in the DRG contributes to the development of oxaliplatin-induced neuropathic pain in rats. The intrathecal drug delivery treatment of activating SIRT1 might be a novel therapeutic option for oxaliplatin-induced neuropathic pain.PMID:37192244

γ-Aminobutyric Acid-Ergic Development Contributes to the Enhancement of Electroencephalogram Slow-Delta Oscillations Under Volatile Anesthesia in Neonatal Rats
CONCLUSIONS: Enhancement of cortical EEG slow-delta oscillations by volatile anesthetics may require mature GABAergic inhibitory transmission during neonatal development.PMID:36753442 | DOI:10.1213/ANE.0000000000006396

Phosphate NIMA-Related Kinase 2-Dependent Epigenetic Pathways in Dorsal Root Ganglion Neurons Mediates Paclitaxel-Induced Neuropathic Pain
CONCLUSIONS: pRSK2/JMJD3/H3K27me3/TRPV1 signaling in the DRG neurons plays as a key regulator for PTX therapeutic approaches.PMID:36753440 | DOI:10.1213/ANE.0000000000006397

Role of Tumor Necrosis Factor Receptor 1-Reactive Oxygen Species-Caspase 11 Pathway in Neuropathic Pain Mediated by HIV gp120 With Morphine in Rats
CONCLUSIONS: These results suggest that spinal TNFRI-mtROS-caspase 11 signal pathway plays a critical role in the HIV-associated neuropathic pain state, providing a novel approach to treating chronic pain in PLWH with opioids.PMID:36662639 | DOI:10.1213/ANE.0000000000006335

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

Oral squamous cell carcinoma–released brain-derived neurotrophic factor contributes to oral cancer pain by peripheral tropomyosin receptor kinase B activation
Oral cancer pain is debilitating and understanding mechanisms for it is critical to develop novel treatment strategies treatment strategies. Brain-derived neurotrophic factor (BDNF) signaling is elevated in oral tumor biopsies and is involved with tumor progression. Whether BDNF signaling in oral tumors contributes to cancer-induced pain is not known. The current study evaluates a novel peripheral role of BDNF-tropomyosin receptor kinase B (TrkB) signaling in oral cancer pain. Using human oral squamous cell carcinoma (OSCC) cells and an orthotopic mouse tongue cancer pain model, we found that BDNF levels were upregulated i...

Sympathectomy decreases pain behaviors and nerve regeneration by downregulating monocyte chemokine CCL2 in dorsal root ganglia in the rat tibial nerve crush model
In this study, we examined the effect of a localized “microsympathectomy,” ie, cutting the gray rami containing sympathetic postganglionic axons where they enter the L4 and L5 spinal nerves, which is more analogous to clinically used sympathetic blockade compared with chemical or surgical sympathectomy. We also examined manipulations of CCL2 (monocyte chemoattractant protein 1), a key player in both regeneration and pain. We used rat tibial nerve crush as a neuropathic pain model in which peripheral nerve regeneration can occur successfully. CCL2 in the sensory ganglia was increased by tibial nerve crush and reduced by...

OPN Deficiency Increases the Severity of Osteoarthritis Associated with Aberrant Chondrocyte Senescence and Apoptosis and Upregulates the Expression of Osteoarthritis-Associated Genes.
Conclusions: The findings of this study suggest that the OPN deficiency can result in accelerated OA, which is associated with enhanced senescence and apoptosis of OA chondrocytes and the upregulated expressions of OA-associated genes. PMID: 33144900 [PubMed - in process]
