In the present study, we examined the contribution of mTOR and its downstream products to brain injuries and neurological deficiencies after cardiac arrest (CA) induced-transient global ischemia. CA was induced by asphyxia followed by cardiopulmonary resuscitation (CPR) in rats. Our results showed that expression of p-mTOR, mTOR-mediated phosphorylation of 4E-binding protein 4 (4E-BP1) and p70 ribosomal S6 protein kinase 1 (S6K1) pathways were amplified in CA rats compared to their controls. Blocking mTOR using rapamycin attenuated upregulation of pro-inflammatory cytokines (namely IL-1\u03b2, IL-6 and TNF-\u03b1), and Caspase-3, indicating cell apoptosis and also promoting the levels of vascular endothelial growth factor (VEGF) and its subtype receptor VEGFR-2 in the hippocampus. Moreover, the effects of rapamycin were linked to improvement of neurological deficits and increased brain water content observed in CA rats. In conclusion, activation of mTOR signal is engaged in pathophysiological process during CA-induced transient global ischemia and blocking mTOR pathway plays a beneficial role in regulating injured neuronal tissues and neurological deficits via PIC, apoptotic Caspase-3 and VEGF mechanisms. Targeting one or more of these specific mTOR pathways and its downstream signaling molecules may present new opportunities for neural dysfunction and vulnerability related to transient global ischemia.<\/jats:p>","DOI":"10.1515\/tnsci-2017-0005","type":"journal-article","created":{"date-parts":[[2017,5,3]],"date-time":"2017-05-03T10:01:41Z","timestamp":1493805701000},"source":"Crossref","is-referenced-by-count":4,"title":["Effects
