The β-site amyloid precursor protein cleaving enzyme 1 (BACE1) is an important regulator for the production of amyloid plaques, a characteristic of the Alzheimer’s disease (AD) brain. The proteolytic cleavage of the amyloid precursor protein (APP), by BACE1, produces an insoluble amyloid-β (Aβ) fragment which has the ability to aggregate and migrate onto the dendrites and cell body of neuronal ...

The gene encoding the beta-amyloid precursor protein has been assigned to human chromosome 21, as has a gene responsible for at least some cases of familial Alzheimer disease. Linkage studies strongly suggest that the beta-amyloid precursor protein and the product corresponding to familial Alzheimer disease are from two genes, or at least that several million base pairs of DNA separate the mark...

Cerebral deposition of beta-amyloid (Abeta) is an invariant event of Alzheimer's disease (AD). We recently described that the brain of aged transgenic mice expressing anti-nerve growth factor (NGF) antibodies (AD11 mice) show a dramatic neurodegenerative phenotype, reminiscent of AD, which includes neuronal loss, cholinergic deficit, and tau hyperphosphorylation, associated with neurofibrillary...

Flavonoids, a group of dietary polyphenols have been shown to possess cognitive health benefits. Epidemiologic evidence suggests that they could play a role in risk reduction in dementia. Amyloid precursor protein processing and the subsequent generation of amyloid beta (Aβ) are central to the pathogenesis of Alzheimer's disease, as soluble, oligomeric Aβ is thought to be the toxic species driv...

Extracting protein interaction relationships from textual repositories, such as MEDLINE, may prove useful in generating novel biological hypotheses. Using abstracts relevant to two known functionally related proteins, we modified an existing natural language processing tool to extract protein interaction terms. We were able to obtain functional information about two proteins, Amyloid Precursor ...
