چکیده انگلیسی
MicroRNA are significant regulators of neuropathic pain development. Neuroinflammation contributes a lot to the progression of neuropathic pain. miR-381 is involved in various pathological processes. However, the role of miR-381 in neuropathic pain development remains barely understood. Therefore, in our study, we aimed to investigate the effects of miR-381 on the process of neuropathic pain progression by establishing a rat model using chronic sciatic nerve injury (CCI). Here, we observed that miR-381 was dramatically decreased in CCI rats. Up-regulation of miR-381 strongly reduced neuropathic pain behaviors including mechanical and thermal hyperalgesia. In addition, inflammatory cytokine expression, including IL-6, IL-10 and TNF-α were significantly repressed by overexpression of miR-381. High mobility group box 1 protein (HMGB1) and Chemokine CXC receptor 4 (CXCR4) participate in neuropathic pain development. In our present study, HMGB1 and CXCR4 were predicted as direct targets of miR-381 by employing bioinformatics analysis. Overexpression of miR-381 was able to restrain the expression of HMGB1 and CXCR4 greatly. The direct correlation between HMGB1 and CXCR4 and miR-381 was confirmed in our research. Furthermore, we found that HMGB1 and CXCR4 were increased in CCI rats time-dependently. Moreover, it was demonstrated that silence of HMGB1 and CXCR4 in CCI rats depressed neuropathic pain progression greatly. In conclusion, it was indicated that miR-381could inhibit neuropathic pain development through targeting HMGB1 and CXCR4.
