Abstract

The deposition and accumulation of amyloid-beta-peptide (Abeta) in the brain are considered a sine qua non for Alzheimer's disease. The experimental delivery of fibrilized Abeta serves as a cellular model for several facets of the disease including the induction of synaptic dysfunction and apoptosis. c-Abl kinase is involved in the regulation of apoptosis and its pro-apoptotic function is in part mediated by its interaction with p73, a p53 homologue. We found that c-Abl activation is involved in cell signals that regulate neuronal death response to Abeta fibrils. Abeta peptide fibrils induced an increase of the c-Abl activity in rat hippocampal neurons as well as an increase in nuclear p73 protein levels and the p73-c-Abl complex. The neuronal cell death induced by Abeta fibrils was prevented by the inhibition of c-Abl with imatinib mesylate (Gleevec or STI571) and by the inhibition c-Abl expression by RNAi. These results directly point to a therapeutic strategy for the treatment of Alzheimer's disease.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
