Effects of Combination of Ketamine with NorBNI on DREAM Protein and Ketamine-Induced Antinociceptive Effect in Formalin-Induced Inflammatory Pain. Idris, L., Suppian, R., & Ismail, Z.
Website abstract bibtex Downstream Regulatory Element Antagonist Modulator (DREAM) protein modulates pain by
regulating c-Fos and prodynorphin genes transcription. The present study investigates the changes of
DREAM protein expression in rat’s spinal cord and ketamine-induced antinociceptive effects upon the
combining administration of ketamine and nor-binaltorphimine dihydrochloride (norBNI) following formalininduced
pain. Male Sprague Dawley rats were divided into several groups: rats administered with normal
saline (C), rats given only formalin injections (F), rats treated with preemptive administration of either norBNI
(N+F) or ketamine (K+F) with formalin injections, and the combination of norBNI and ketamine (NK+F)
administration with formalin injection. Formalin (5%) was injected subcutaneously to the rats’ hind paws, and
the pain behavior was recorded for one hour. After two hours, the rats were sacrificed, and their spinal cords
(L4-L5) were removed for western blot analysis. Results: Ketamine-induced antinociceptive effect on the pain
behavior responses were apparently suppressed following the combination with norBNI (NK+F). However,
there was no change in spinal DREAM protein levels detected between K+F and NK+F group. Conclusion:
The suppression effect of the ketamine-induced antinociceptive effect was attenuated when combined with
norBNI, though not through the modulation of genes transcriptional mechanism regulated by the DREAM
protein.
