Quantitative neuroproteomics of an in vivo rodent model of focal cerebral ischemia/reperfusion injury reveals a temporal regulation of novel pathophysiological molecular markers.

Cerebral ischemia or stroke, an acute neurological injury lacking an effective therapy, is the second leading cause of death globally. The unmet need in stroke research is to identify viable targets and to understand their interplay during the temporal evolution of ischemia/reperfusion (I/R) injury. Here we report a temporal signature of the ischemic hemisphere revealed by the isobaric tag for relative and absolute quantification (iTRAQ)-based 2D-LC-MS/MS strategy in an in vivo middle cerebral artery occlusion (MCAO) model of focal cerebral I/R injury.
