Suppression of histone deacetylases by SAHA relieves bone cancer pain in rats via inhibiting activation of glial cells in spinal dorsal horn and dorsal root ganglia

Robust activation of glial cells has been reported to occur particularly during the pathogenesis of bone cancer pain (BCP). Researchers from our group and others have shown that histone deacetylases (HDACs) pl...

CONCLUSIONS: Intrathecal pioglitazone administration alleviates BCP by regulating the PPARγ/PTEN/mTOR signal in the SDH. Our data provided new insight in the therapeutic strategy in BCP management. PMID: 32942156 [PubMed - as supplied by publisher]

Cancer pain is one of the most common and serious symptoms of cancer patients. At present, the agents used for the prevention or treatment of cancer pain do not act with optimal safety and efficacy. The nuclear factor kappa B (NF-κB) signaling pathway and its downstream inflammatory factors interleukin-6 (IL-6), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α) play an important regulatory role in the developmental process of cancer pain. IKKβ is a key molecule of the IκB (IKK) kinase that propagates cellular responses to inflammation. Previous studies have shown that phosph...

In this study, the antinociceptive effects of liquiritin, which is an active component extracted from Glycyrrhizae Radix, were tested and the underlying mechanisms targeting spinal dorsal horn (SDH) were investigated. The BCP group displayed a significant decrease in the mechanical withdrawal threshold on days 6, 12, and 18 when compared with sham groups. Intrathecal administration of different doses of liquiritin alleviated mechanical allodynia in BCP rats. The results of immunofluorescent staining and western blotting showed that liquiritin inhibited BCP-induced activation of astrocytes in the spinal cord. Moreover, intr...

This study evaluated its antinociceptive effects in pain hypersensitivity and explored the underlying mechanisms. The data showed that subcutaneous lemairamin injection dose-dependently inhibited formalin-induced tonic pain but not acute nociception in mice and rats, while intrathecal lemairamin injection also dose-dependently produced mechanical antiallodynia in the ipsilateral hindpaws of neuropathic and bone cancer pain rats without affecting mechanical thresholds in the contralateral hindpaws. Multiple bi-daily lemairamin injections for 7 days did not induce mechanical antiallodynic tolerance in neuropathic rats. Moreo...

This study further explored the dual μ-opioid receptor and norepinephrine reuptake mechanisms underlying dezocine-induced mechanical antiallodynia in bone cancer pain, compared with tapentadol, the first recognized analgesic in this class. Dezocine and tapentadol, given subcutaneously, exerted profound mechanical antiallodynia in bone cancer pain rats in a dose-dependent manner, yielding similar maximal effects but different potencies: ED50s of 0.6 mg/kg for dezocine and 7.5 mg/kg for tapentadol, respectively. Furthermore, their mechanical antiallodynia was partially blocked by intrathecal injection of the specific ...
