BECN1 and ischemic stroke: Several studies in recent years have reported on this, Wang et al. [31] found knockout in studies glucocorticoid-regulated kinase 1 (SGK1) knockdown upregulated beclin-1 and LC-3 expression mediated by Intracarotid cold saline infusion (ICSI), This suggests that ICSI has a neuroprotective effect on ischemic stroke after reperfusion through up-regulation of SGK1 and inhibition of autophagy.
