Heat Shock Protein 90 Regulates the Metaphase-Anaphase Transition in a Polo-Like Kinase-Dependent Manner

Published version of a preprint

Abstract

We have shown previously that the molecular chaperone heat shock protein 90 (Hsp90) is required for a proper centrosome function. Indeed, this Hsp90 function seems to be reflected in Polo-like kinase stability. Inhibition of Hsp90 in HeLa cells results in cell cycle arrest either in G2 stage or at the metaphase-anaphase transition. Here, we show that this inhibition leads to inactivation of the anaphase-promoting complex or cyclosome by both dephosphorylation and induction of the spindle assembly checkpoint. Hsp90 inhibition compromises two of the main mitotic kinases, Polo-like kinase 1 (Plk1) and cdc2. Interestingly, this mitotic arrest does not occur in certain tumor cell lines where Hsp90 and Plk1 are not associated. Those cells are able to process mitosis successfully and have an active Plk1 despite Hsp90 inactivation. Therefore, it seems that Hsp90 regulates completion of mitosis depending on its association with Plk1.

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.
