As an important mediator of apoptosis, p53 is activated by damages such as hypoxia.192 The combination of Notch with p53 is crucial for neuronal apoptosis during ischemic stroke, which majorly involves stabilization of p53 and transcriptional regulation of p53 and NICD target genes.193 Besides, Pin1, an isomerase that regulates p53 transactivation, is deemed to be involved in the pathogenesis of ischemic stroke, which is also related with Notch signaling and is responsible for ischemic stroke-induced neuronal death and neurological deficits.194. The gene discussed is PIN1; the disease is ischemic stroke.
