Abstract

Significance Oncogenic KRAS underlies 30–90% of lung, colon, and pancreatic cancers, but despite more than 30 y of research, clinical inhibitors of KRAS—and potential resistance mechanisms—remain elusive. Using CRISPR-mediated genome editing of oncogenic Kras , we show that some lung cancer cells can survive Kras knockout, indicating the existence of mechanisms that allow tumors to escape Kras oncogene addiction. We identify genes highly expressed in Kras knockout cells, including the Fas receptor gene. Antibodies that activate Fas receptor selectively induced apoptosis in Kras-independent lung cancer cells, suggesting a potential strategy for combinatorial therapies against Kras-driven tumors. These findings have direct translational implications for the treatment of lung cancer and other KRAS mutant cancer types.

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.
