Abstract

The underlying pathomechanisms in prion infections of the central nervous system are still insufficiently understood. The identification of genes with altered expression patterns in the diseased brain may provide insight into the disease development on the molecular level, which ultimately leads to neuronal loss. To provide a detailed analysis of changes in the molecular level in prion disease pathology we used a large-scale gene array based approach, which covers more than 11,000 functionally characterised sequences and expressed sequence tags, for the analysis of gene expression profile alterations in the cortex, medulla, and pons of scrapie-infected mice. The study identified in total 114 genes with altered mRNA levels, the majority of which were previously not known to be affected by the disease. Overall the gene array data demonstrate the presence of a strong inflammatory reaction and stress response, and show similarities to gene expression patterns found in brains affected by Alzheimer's disease and aging, respectively.

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.
