JNK-mediated Neuroprotective Mechanism after Ischemic Stroke in Rats / 中国生物化学与分子生物学报

In order to explore the protective mechanism of stress-activated protein kinase JNK on neurons after ischemic stroke,the model of middle cerebral artery occlusion (MCAO) in male SD rats was established by suture methods. Anisomycin (AN), a JNK agonist, was added at the characteristic time point of autophagy, and then Western blotting and immunofluorescence were used to detect the protein expression of autophagy flow pathways in ischemic penumbra, and the effects of JNK on the stability of Bcl-2-Beclin1 complex and autophagy flow pathway were analyzed. The results showed that compared with the MCAO+Veh group, the expression levels of LC3 (
