Tg(APPV717F)109Ili

Overexpression of a human APP (hAPP) minigene encoding the APP717V to F mutation associated with familial Alzheimer's Disease. The construct contained APP introns 6 - 8, allowing alternative splicing of exons 7 and 8. The transgene utilizes a platelet-derived growth factor promoter (PDGF-b) and the three major splicing variants of hAPP mRNA were expressed in transgenic mice. As determined by RNAse protection, line 109 expressed ~ 18-fold more APP than previously described neuron-specific enolase (NSE)-promoter-driven APP transgenes. (J:23080, J:100980)
