Using i-Fect to Knock Down GLT-1 Gene in vivo

Pain Researchers continue to use our i-FectTM Transfection Kit for Gene Expression AnalysisValproate Prevents Dysregulation of Spinal Glutamate and Reduces the Development of Hypersensitivity in Rats After Peripheral Nerve Injury. The Journal of Pain, Volume 14, Issue 11, November 2013, Pages 1485–1491 http://dx.doi.org/10.1016/j.jpain.2013.07.007.Researchers use the kit to deliver Glutamate Receptor 1 siRNA in vivo.The present study examined whether the histone deacetylase inhibitor valproate prevents downregulation of glutamate transporters in the primary cultured astrocytes and in the spinal cord after L5-L6 spinal nerve ligation (SNL) and whether this action of valproate on spinal glutamate transporters prevents spinal glutamate dysregulation and development of hypersensitivity after SNL. In cultured astrocytes, valproate prevented downregulation of glutamate transporter-1 (GLT-1) and glutamate-aspartate transporter in a concentration-dependent manner. Repeated oral administration of valproate reduced the development of hypersensitivity and prevented the downregulation of spinal GLT-1 and glutamate-aspartate transporter expression in rats after SNL, but did not affect mechanical nociception and expression of those transporters in normal rats. Valproate's effects on hypersensitivity and spinal GLT-1 expression in SNL rats were blocked by intrathecal administration of the selective GLT-1 blocker dihydrokainic acid or the GLT-1 selective small interfering RNA (siRNA).
