BECN1 and Cerebral ischemia: <h4>Objective</h4>To investigate the effects of postconditioning ischemia on the expressions of the hippocampus neuron autophagy-related proteins LC3-II and Beclin-1 in rats following cerebral ischemia reperfusion.<h4>Methods</h4>A total of 128 male Sprague-Dawley rats were randomly divided into 4 groups: control, cerebral ischemia-reperfusion (IR), cerebral ischemia post-conditioning group (IP), and PI3K/Akt inhibitor (LY294002).
