Abstract:

Objective: The present study sought to detect spinal sirtuin 1 (SIRT1) and acetylation of histone H3 (Ac-H3) expression in rats with burn injury pain (BIP model). Procedures and Results: A BIP model was first established. BIP rats showed lower paw withdrawal threshold (PWT) from day 1, which persisted for 21 days following the burn injury. Spinal SIRT1/Ac-H3 expression increased following burn injury. The intrathecal use of resveratrol increased PWT and SIRT1 expression but induced down-regulation of Ac-H3 expression. We first demonstrated that the inhibition of SIRT1 significantly induced mechanical allodynia in naïve rats. The preinjection of SIRT1 inhibitor partly antagonized the analgesic effects of resveratrol in BIP rats. Conclusion: Inhibition of SIRT1 produces pain facilitation in the naïve rats. The expression of spinal SIRT1 increased after burn injury in the BIP model. The activation of spinal SIRT1 might mediate the resveratrol-induced analgesic effects.
