c-Raf, but not B-Raf, is essential for development of K-Ras oncogene-driven non-small cell lung carcinoma

Open access

Abstract

We have investigated the role of individual members of the Raf/Mek/Erk cascade in the onset of K-Ras oncogene-driven non-small cell lung carcinoma (NSCLC). Ablation of Erk1 or Erk2 in K-Ras oncogene-expressing lung cells had no significant effect due to compensatory activities. Yet, elimination of both Erk kinases completely blocked tumor development. Similar results were obtained with Mek kinases. Ablation of B-Raf had no significant effect on tumor development. However, c-Raf expression was absolutely essential for the onset of NSCLC. Interestingly, concomitant elimination of c-Raf and B-Raf in adult mice had no deleterious consequences for normal homeostasis. These results indicate that c-Raf plays a unique role in mediating K-Ras signaling and makes it a suitable target for therapeutic intervention.

  • C-RAF rather than B-RAF plays a crucial role in mediating KRAS oncogenic signaling.

    “Recent studies showed that C-RAF rather than B-RAF plays a crucial role in mediating KRAS oncogenic signaling (74, 75).”

  • 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.
