Staurosporine‐Induced Activation of Caspase‐3 Is Potentiated by Presenilin 1 Familial Alzheimer's Disease Mutations in Human Neuroglioma Cells

Abstract excerpt

Familial Alzheimer's disease (FAD) mutant forms of presenilin 1 (PS1) and 2 have been shown to sensitize cells to apoptotic cell death. Here we explore the effects of FAD mutant forms of PS1 on caspase activation during apoptosis. We show that caspase activation leads to increased generation of alternative C-terminal fragments (CTFs) from mutant as compared to wild-type (wt) PS1. For this purpose, very low...
