Analysis of p53 Apoptotic Pathways in Ischemic Stroke

In addition to extrinsic apoptosis pathway and intrinsic apoptosis pathway, another programmed cell death process is largely dependent on p53 in ischemic stroke. The tumor suppressor p53 regulates key cellular processes including cell cycle arrest, DNA repair, senescence, and apoptosis. A large number of in vitro and in vivo studies have demonstrated the role of p53 in neuronal apoptosis and its accumulation in apoptotic lesions after cerebral ischemia. Furthermore, genetic deletion and pharmacologic inhibition of p53 prevent neuronal injury and improve functional recovery after stroke. However, the specific mechanism of neuronal damage by p53 in ischemic stroke is unknown and requires further investigation. Understanding the mechanisms that mediate p53 regulation and brain damage after stroke may help identify targets for neuroprotective therapy.
