Abstract

ABSTRACT Covalent inhibitors of the KRAS G12C oncoprotein have recently been developed and are being evaluated in clinical trials. Resistance to targeted therapies is common and likely to limit long-term efficacy of KRAS inhibitors (KRASi). To identify pathways of adaptation to KRASi and to predict drug combinations that circumvent resistance, we used a mass spectrometry-based quantitative temporal proteomics and bioinformatics workflow to profile the temporal proteomic response to KRAS G12C inhibition in pancreatic and lung cancer 2D and 3D cellular models. We quantified 10,805 proteins across our datasets, representing the most comprehensive KRASi proteomics effort to date. Our data reveal common mechanisms of acute and long-term response between KRAS G12C -driven tumors. To facilitate discovery in the cancer biology community, we generated an interactive ‘KRASi proteome’ website ( https://manciaslab.shinyapps.io/KRASi/ ). Based on these proteomic data, we identified potent combinations of KRASi with PI3K, HSP90, CDK4/6, and SHP2 inhibitors, in some instances converting a cytostatic response to KRASi monotherapy to a cytotoxic response to combination treatment. Overall, using our quantitative temporal proteomics-bioinformatics platform, we have comprehensively characterized the proteomic adaptations to KRASi and identified combinatorial regimens to induce cytotoxicity with potential therapeutic utility.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Acquired resistance to KRASG12C inhibition may be mediated by activation of multiple RTK regulators, including EGFR, FGFR, IGF1R, HER2, SHP2, and downstream RAS effectors such as MYC and mTOR.

    “Recent studies using preclinical models have indicated that acquired resistance to KRASG12C inhibition may be mediated by the activation of multiple receptor tyrosine kinase (RTK) regulators, including epidermal growth factor receptor (EGFR), fibroblast growth factor receptor (FGFR), insulin-like growth factor 1 receptor (IGF1R), human epidermal growth factor 2 (HER2), and Src homology 2 domain-”
  • Inhibition of multiple RTKs through adaptors like SOS and SHP2 has shown promise in preclinical studies for mitigating acquired resistance to KRAS inhibition.

    “Previously, inhibition of multiple RTKs through adaptors like SOS and SHP2, which function downstream of RTKs to promote RAS activation, has shown promise in preclinical studies aimed at mitigating acquired resistance to KRAS inhibition.7,22,26”
  • One major route leading to recovery of RAS activity is activation of RTKs through genetic or non-genetic mechanisms.

    “One major route leading to such recovery of RAS activity is the activation of RTKs through either genetic (e.g., gene amplification or fusion) or non-genetic mechanisms.2,4,5,6,7,8,22,23,24,25”

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.
