Abstract

Abnormalities in tau mRNA splicing cause frontotemporal dementia and parkinsonism linked to chromosome 17, and similar alterations are suggested in sporadic tauopathies such as progressive supranuclear palsy (PSP) or corticobasal degeneration (CBD). We have analyzed the expression of three-repeat (3R) and four-repeat (4R) tau isoforms in brains with familial and sporadic tauopathies. By RT-PCR analysis, decreased levels of 3R tau mRNA were detected not only in severely affected cases with progressive supranuclear palsy or corticobasal degeneration but also in cases with Alzheimer's disease or Pick's disease. Levels of 3R tau transcripts were closely correlated with levels of neurofilament transcripts. By contrast, expressions of glial fibrillary acidic protein and myelin basic protein were similar in all brains. These results suggest that decrease of 3R tau mRNA associated with loss of neuronal element may largely contribute to the increased ratio of 4R/3R tau mRNA in sporadic tauopathies.

  • 4R tau expression is increased in vulnerable brain regions and NFT bearing neurons in AD brain.

    “Expression of tau isoforms in AD brain is complicated; although it is still under debate that whether the overall 3R:4R tau ratio is altered, several studies support a notion that 4R tau expression is increased in vulnerable brain regions and NFT bearing neurons in AD brain [111, 113–118].”

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.
