Abstract

Five-year survival for pancreatic ductal adenocarcinoma (PDAC) patients remains below 7% due to the lack of effective treatments. Here, we report that combined ablation of EGFR and c-RAF expression results in complete regression of a significant percentage of PDAC tumors driven by Kras/Trp53 mutations in genetically engineered mice. Moreover, systemic elimination of these targets induces toxicities that are well tolerated. Response to this targeted therapy correlates with transcriptional profiles that resemble those observed in human PDACs. Finally, inhibition of EGFR and c-RAF expression effectively blocked tumor progression in nine independent patient-derived xenografts carrying KRAS and TP53 mutations. These results open the door to the development of targeted therapies for PDAC patients.

  • Combined inhibition of C-Raf and Egfr induced complete regression of pancreatic ductal adenocarcinomas in Kras/Trp53-driven GEM models and PDXs without apparent toxicity.

    “combined inhibition of C-Raf and Egfr induced complete regression of pancreatic ductal adenocarcinomas in Kras/Trp53-driven GEM models and PDXs without apparent toxicity (77).”

  • C-Raf, but not B-Raf or A-Raf, may mediate the oncogenic signaling in KRAS-driven cancer.

    “Together, these studies provided compelling evidence that C-Raf, but not B-Raf or A-Raf, may mediate the oncogenic signaling in KRAS-driven 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.
