Abstract
Paclitaxel-induced peripheral neuropathic pain (PIPNP) is a major therapy- and dose-limiting side effect that is extremely laborious to treat. Resveratrol (Res), with a structure name of 3,5,40-trihydroxystilbene, is a kind of natural polyphenolic chemical with plenty of useful characteristics such as anti-inflammatory, and anti-oxidative stress. However, the impact of Res on PIPNP remains unclear. Therefore, the current study intends to examine the analgesic effect of Res on PIPNP. In the present study, the results revealed that Res could effectively prevent the development of paclitaxelinduced PIPNP in a dose-dependent manner when repeated doses of Res were given during PIPNP induction. This prophylactic effect of Res was involved in inhibited paclitaxel-induced up-regulation of TRPV1 instead of TRPA1 in the dorsal root ganglia. Furthermore, the inhibition of TRPV1 upregulation by Res may be involved in a phosphorylation of ERK mechanism. In summary, we conclude that Res plays an intriguing role in the prevention of PIPNP and thus may work as a therapeutic compound for treating and preventing PIPNP.
