APP carboxyl-terminal fragment without or with A? domain equally induces cytotoxicity in differentiated PC12 cells and cortical neurons

Abstract: Mutations in the beta-amyloid precursor protein (APP) gene cause familial Alzheimer's disease (AD). Although amyloid beta peptide (Abeta) is the principal constituent of senile plaques in AD, other cleavage products of APP are also implicated in playing a role in the pathogenesis of AD. C-terminal fragments of APP (APP-CTs), that contain complete Abeta sequence, are found in neuritic plaques, neurofibrillary tangles and the cytosol of lymphoblastoid cells obtained from AD patients. Our previous report demonstr… Show more

“…To examine the Rab5 + endosomes in axons, we expressed C99 and C83 following NGF treatment. Consistent with earlier studies (73)(74)(75), expression of C99 markedly suppressed NGF-induced activation of Erk1/2 at both 5 and 30 minutes (Supplemental Figure 2, B and C). While having no effect at 5 minutes, C83 induced a small decrease in pErk1/2 at 30 minutes.…”

“…Generally, APP is a marker for cell differentiation, however, previous studies also demonstrated that the overexpression of APP could inhibite neurite outgrowth in N2a cell [16]. Its membrane location and its structural similarities with cysteine-rich growth factors suggest that APP might be functioning as a cell surface receptor or growth factor [17], and such proteins, such as G0 protein [18], Fe65 [19], and low density lipoprotein receptor-related protein [20], have been reported as its ligands.…”

“…AICD harbors several internalization and trafficking motifs and might possess transcriptional activity that resembles the Notch1-IC of Notch1 (Baek et al, 2002;Cao and Sudhof, 2001;Gao and Pimplikar, 2001). AICD regulates phosphoinositide-mediated calcium signaling in vitro (Leissring et al, 2002) and also induces apoptosis and cytotoxicity in neurons (Lee et al, 2000). Previous reports have suggested the possibility of crosstalk between the Notch and APP signaling pathways, which would manifest as -secretase substrate competition (Berezovska et al, 2001;Lleo et al, 2003).…”
