Dynamics of gene expression for a hippocampal glycoprotein elevated in Alzheimer's disease and in response to experimental lesions in rat

Abstract

A hippocampal poly(A) RNA, pADHC-9, was cloned by differential screening of a human hippocampal cDNA library. By RNA blot analysis, pADHC-9 was elevated 2-fold in Alzheimer's disease hippocampus. In situ analyses identified pADHC-9 expression in pyramidal and non-pyramidal cells of the hippocampus and entorhinal cortex. Nucleotide sequence analysis identified pADHC-9 as a potential human homolog of rat sulfated glycoprotein 2 (SGP-2). SGP-2 expression increased in rat hippocampus following experimental lesions that mimic intrinsic neuronal loss and/or deafferentation. The function of pADHC-9 in brain has not been defined, but in serum, a similar protein inhibits complement-dependent cytolysis. Increased expression of pADHC-9 in Alzheimer's disease hippocampus may be a compensatory response mounted to retard a complement-driven neurodegenerative cascade.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Clusterin was first linked to Alzheimer's disease in 1990, when it was found elevated in the hippocampi of AD patients.

    “CLU was first associated with Alzheimer’s disease (AD) in 1990 when it was found to be increased in the hippocampi of AD patients (May, et al., 1990)”

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.
