Epigallocatechin Gallate Extends the Therapeutic Window of Recombinant Tissue Plasminogen Activator Treatment in Ischemic Rats.
Journal of Stroke and Cerebrovascular Diseases : the Official Journal of National Stroke Association 2016 April
BACKGROUND: Ischemic stroke is the leading cause of death and disability worldwide. To date, recombinant tissue plasminogen activator (rt-PA) remains the only safe and effective pharmaceutical treatment for brain ischemia, but delayed rt-PA administration leads to hyperperfusion, which severely limits its clinical efficacy.
METHODS: In this study, we investigated the effect of epigallocatechin gallate (EGCG) in extending the therapeutic window of rt-PA using a rat middle cerebral artery occlusion (MCAO) model.
RESULTS: Simultaneous treatment of EGCG and rt-PA significantly recovered the neurobehavioral deficit, when administered even 4 hours after MCAO. Pathological examinations on the ischemic brain samples revealed that EGCG significantly alleviated the common side effects of delayed rt-PA treatment, including brain infarction, cerebral edema, and blood-brain barrier disruption. We further found that EGCG exerted its protective functions against delayed rt-PA through upregulation of plasminogen activator inhibitor-1, as well as downregulation of matrix metalloproteinases.
CONCLUSION: Our study has demonstrated for the first time in vivo results supporting the potential of EGCG to be coadministered with rt-PA, to extend its therapeutic window in treating acute brain ischemia.
