Altered microRNA expression in the ischemic-reperfusion spinal cord with atorvastatin therapy

J Pharmacol Sci. 2013;121(4):343-6. doi: 10.1254/jphs.12235sc. Epub 2013 Mar 20.

Abstract

We explored the neuroprotection by atorvastatin in the ischemia/reperfusion model of rat and its microRNA-related mechanisms. At first, we uncovered a previously unknown alteration in temporal expression of a large set of microRNAs following spinal cord ischemia-reperfusion injury (IRI). The target genes for the differentially expressed microRNAs include genes encoding components that are involved in the inflammation, apoptosis, and neural damage that are known to play important roles in IRI. Atorvastatin pretreatment restored part of the up or down regulations. These findings suggest that altered expression of microRNAs may contribute to the mechanism of neuroprotection of statins in spinal cord IRI.
