Abstract:
This study aimed to investigate the analgesic effect of chlorogenic acid on cisplatin-induced neuropathic pain and explored the underlying molecular mechanisms. The animal experimental protocol has been reviewed and approved by Laboratory Animal Ethics Committee of Xinxiang Central Hospital, in compliance with the Institutional Animal Care Guidelines. Von Frey hair and a radiant heat was employed to measure mechanical allodynia and thermal hyperalgesia; Western blot was used to examine transient receptor potential vanilloid type-1 (TRPV1) protein expression in the rat dorsal root ganglion (DRG); patch clamp was used to record TRPV1 currents in DRG neurons. The experimental results showed that chlorogenic acid could attenuate cisplatin-induce mechanical allodynia and thermal hyperalgesia in rats. The expression of TRPV1 protein in DRGs was increased in cisplatin-treated rats, while chlorogenic acid also could reverse cisplatin-induced the upregulation of TRPV1 protein. Forthermore, chlorogenic acid could attenuate cisplatin-mediated the upregulation of TRPV1 current density. These above results indicated that chlorogenic acid could alleviate cisplatin-induced pain hypersensitivity through inhibition of the expression and function of TRPV1 in rats.
