Complex Regulation of p73 Isoforms after Alteration of Amyloid Precursor Polypeptide (APP) Function and DNA Damage in Neurons

Abstract

Background: Alterations of the APP pathway or DNA damage induce neuronal cell death. Results: Alterations of the APP pathway or DNA damage increase TAp73 expression and reduce Delta Np73 protein levels. Conclusion: A tight control of the expression of p73 isoforms participates in neuronal cell death. Significance: p73 isoforms may play a role in neurodegenerative diseases such as Alzheimer and in the neurotoxicity of anticancer drug therapies
