Non-A.beta. Component of Alzheimer's Disease Amyloid (NAC) is Amyloidogenic
Abstract
The non-A beta component of Alzheimer's disease (AD) amyloid (NAC) was identified biochemically as the second major component in the amyloid purified from brain tissue of AD patients. NAC, derived from its 140 amino acid long precursor, NACP, is at least 35 amino acids long (NAC35) although its amino terminus is not definitely determined. An antiserum, anti-NAC-X1, was raised against the amino-terminal 9 amino acid sequence of NAC35 and purified on a peptide affinity column. This affinity-purified anti-NAC-X1 antibody immunostained amyloid in AD brain sections and recognized NAC35 but not NACP on Western or dot blot. In aqueous solutions, synthetic NAC35 self-aggregated in a time-, concentration-, and temperature-dependent manner. NAC35 was detected initially as a monomer with a molecular mass of 3500 Da but became aggregated as a function of time into a higher molecular mass component that could not migrate into the gel. The aggregate of NAC35 showed green-gold birefringence after Congo red staining when analyzed under polarized light and fiber-like structure when analyzed ultrastructurally. These results suggest that NAC can form amyloid after it has been cleaved out of its precursor and may be a crucial factor in amyloidosis in the AD brain.

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.
