miR-384-5p ameliorates neuropathic pain by targeting SCN3A in a rat model of chronic constriction injury.
Objective: To explore the potential regulation mechanisms of miR-384-5p in Neuropathic pain (NP). Methods: Rat model of chronic constriction injury (CCI) was established to induce NP in vivo. NP levels were assessed using Withdrawal Threshold (PWT) and Paw Withdrawal Latency (PWL). qPCR and Western blotting were used to determine the relative expression of miR-384-5p and SCN3A. ⋯ Dual-luciferase reporter assays indicated that SCN3A is a target gene of miR-384-5p. Conclusion: miR-384-5p is a negative regulator in the development of neuropathic pain by regulating SCN3A, indicating that miR-384-5p might be a promising therapeutic target in the treatment of neuropathic pain.
