title: The cyclic AMP response element-binding protein antisense oligonucleotide induced anti-nociception and decreased the expression of KIF17 in spinal cord after peripheral nerve injury in mice.
abstract: BACKGROUND
  The cyclic AMP response element-binding protein (CREB) plays an important role in neuropathic pain. Kinesin superfamily motor protein 17 (KIF17) is involved in long-term memory formation. CREB could increase the level of KIF17 when activated by synaptic input. This study is to investigate the role and mechanism of CREB antisense oligonucleotide (ODN) in neuropathic pain induced by chronic constriction injury (CCI) in mice.
  
  
  RESULTS
  CCI surgery decreased thresholds of mechanical allodynia and thermal hyperalgesia whereas CREB antisense oligonucleotide ODN significantly attenuated these pain behaviors (P < 0.05). CCI significantly induced the protein expression of phosphorylated CREB (pCREB) and KIF17, but not KIF5B, in the spinal cord of CCI mice (P < 0.05). Additionally, the mRNA expression of CREB and KIF17 was significantly increased by CCI (P < 0.05). However, CREB antisense ODN significantly decreased the protein expression of pCREB and KIF17 (but not KIF5B), and the mRNA expression of CREB and KIF17 (P < 0.05).
  
  
  CONCLUSIONS
  CREB antisense oligonucleotide ODN may reduce neuropathic pain through targeting CREB and decreasing the expression of pCREB and KIF17.
