Abstract

Introduction: Altered cell cycle reentry has been observed in Alzheimer's disease (AD). Denticleless (DTL) was predicted as the top driver of a cell cycle subnetwork associated with AD. Methods: We systematically investigated DTL expression in AD and studied the molecular, cellular, and behavioral endophenotypes triggered by DTL overexpression. Results: We experimentally validated that CDT2, the protein encoded by DTL , activated cyclin‐dependent kinases through downregulating P21, which induced tau hyperphosphorylation and Aβ toxicity, two hallmarks of AD. We demonstrated that cyclin‐dependent kinases inhibition by roscovitine not only rescued CDT2‐induced cognitive defects but also reversed expression changes induced by DTL overexpression. RNA‐seq data from the DTL overexpression experiments revealed the molecular mechanisms underlying CDT2 controlled cell cycle reentry in AD. Discussion: These findings provide new insights into the molecular mechanisms of AD pathogenesis and thus pave a way for developing novel therapeutics for AD by targeting AD specific cell cycle networks and drivers.

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

  • The reason for tau hyperphosphorylation is a mutation in the tau genes or dysregulation of kinases and phosphatases.

    “The reason stated for the hyper phosphorylation is a mutation in the tau genes or dysregulation of kinases as mentioned below and phosphatases which catalyze the phosphorylation process [7].”

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.
