Amyloid, the presenilins and Alzheimer's disease
Hardy J.. Trends in neurosciences, 1997-04-01
Topic: Disease mechanisms in lab and animal studies
Various mutations in the amyloid protein precursor and presenilin genes can lead to early onset, autosomal Alzheimer's disease. A series of mis-sense mutations (with one exception) in each of these genes has been shown to cause disease in a fully penetrant fashion. It has recently been shown, both in vivo and in model systems, that tissues expressing these mutations have increased production of amyloid (A beta) ending at residue 42. It has also recently been shown that this form of A beta is deposited early and selectively in the disease process and is more fibrillogenic in vitro. It is argued that these genetic and molecular biological data provide strong support for the veracity of the 'amyloid cascade hypothesis' for disease pathogenesis, and that this hypothesis offers a coherent framework for drug discovery.
Key findings
- It has also recently been shown that this form of A beta is deposited early and selectively in the disease process and is more fibrillogenic in vitro.

How this study scored 36/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
