NERVE GROWTH FACTOR-INDUCED NEURONAL DIFFERENTIATION IS ACCOMPANIED BY DIFFERENTIAL SPLICING OF BETA-AMYLOID PRECURSOR MESSENGER-RNAS IN THE PC12 CELL-LINE
The effect of the neurotrophic factor nerve growth factor (NGF) on the expression of the beta-amyloid gene has been studied in the clonal nerve cell line PC12. The neuronal differentiation of PC12 cells in the presence of NGF was accompanied by a shift in the ratio of beta-amyloid precursor protein (APP) transcripts. In particular there was reduced expression of the transcript coding for the longest precursor form (APP770) and a concomitant increase in the shortest (APP695) transcript following NGF treatment.
