Abstract

Significance: Cytotoxic therapy is still the backbone of effective chemotherapy, although most current pharmaceutical interest is in targeted therapy. Our findings concern a general adaptive response of cells that causes resistance to gemcitabine and 15 other FDA-approved cytotoxic drugs when cells are grown at high density. Although on the surface cell confluence seems like it could be an irrelevant property of cells in culture, our work shows that it is very relevant to tumors in mice and retrospectively to the success of chemotherapy in humans. On a fundamental cell biological level, these studies identify a previously unappreciated function of the enigmatic Hippo pathway, which controls this response. “Switching-off” this pathway could present an opportunity to overcome drug resistance in pancreatic cancer.

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.
