Inhibition of neurite outgrowth by familial Alzheimer's disease-linked presenilin-1 mutations.

Abstract excerpt

Two (P117L; M146L) familial Alzheimer's disease (FAD)-causing presenilin-1 (PS1) mutations have been tested fortheir effect in stably transfected mouse neuroblastoma (N2a) cell lines. The P117L mutation is associated with the earliest onset of AD reported so far (24 years), while the M146L is less pathogenic with the onset at about 43 years. Overexpression of wild-type (wt) PS1 gene was associated with the marked...
