Genome-Wide CRISPR Screens Identify Multiple Synthetic Lethal Targets That Enhance KRASG12C Inhibitor Efficacy

Open access

Published version of a preprint

Abstract

Non–small lung cancers (NSCLC) frequently (∼30%) harbor KRAS driver mutations, half of which are KRASG12C. KRAS-mutant NSCLC with comutated STK11 and/or KEAP1 is particularly refractory to conventional, targeted, and immune therapy. Development of KRASG12C inhibitors (G12Ci) provided a major therapeutic advance, but resistance still limits their efficacy. To identify genes whose deletion augments efficacy of the G12Cis adagrasib (MRTX-849) or adagrasib plus TNO155 (SHP2i), we performed genome-wide CRISPR/Cas9 screens on KRAS/STK11-mutant NSCLC lines. Recurrent, potentially targetable, synthetic lethal (SL) genes were identified, including serine–threonine kinases, tRNA-modifying and proteoglycan synthesis enzymes, and YAP/TAZ/TEAD pathway components. Several SL genes were confirmed by siRNA/shRNA experiments, and the YAP/TAZ/TEAD pathway was extensively validated in vitro and in mice. Mechanistic studies showed that G12Ci treatment induced gene expression of RHO paralogs and activators, increased RHOA activation, and evoked ROCK-dependent nuclear translocation of YAP. Mice and patients with acquired G12Ci- or G12Ci/SHP2i-resistant tumors showed strong overlap with SL pathways, arguing for the relevance of the screen results. These findings provide a landscape of potential targets for future combination strategies, some of which can be tested rapidly in the clinic. Significance: Identification of synthetic lethal genes with KRASG12C using genome-wide CRISPR/Cas9 screening and credentialing of the ability of TEAD inhibition to enhance KRASG12C efficacy provides a roadmap for combination strategies.

  • The paper relies on this without support.

    The four KRAS G12C-mutant NSCLC cell lines with STK11 and KEAP1 co-mutations are representative of KRAS G12C-mutant NSCLC with these co-mutations.

    “we chose lines with co-mutations in STK11; three were also KEAP1-defective.”
  • The paper relies on this without support.

    CRISPR/Cas9 dropout under drug treatment in these cell lines identifies genes whose inactivation enhances drug efficacy.

    “we used genomewide CRISPR/Cas9 screening to identify genes whose inactivation enhances the efficacy of MRTX-849 alone or in combination with TNO-155 in four KRAS G12C -mutant NSCLC cell lines.”
  • The paper relies on this without support.

    The KCL mouse model and H2030 xenografts model human KRAS G12C NSCLC response and resistance.

    “we developed G12Ci-and G12Ci+SHP2i-resistant genetically engineered mouse models (GEMMs, see Methods for details).”
  • The paper relies on this without support.

    Enriched pathways in resistant mouse and patient tumors indicate resistance mechanisms relevant to human KRAS G12C NSCLC.

    “resistance pathways suggested by our CRISPR/ Cas9 SL screens and the resistant GEMMs also were enriched in these patient samples.”
  • The paper relies on this without support.

    KRAS G12C inhibitors have so far produced only modest efficacy in the clinic.

    “yet their efficacy in the clinic has thus far been modest.”
  • The authors state this as an assumption.

    VRK2 is expressed at the protein level in NSCLC.

    “assuming that VRK2 is also expressed at the protein level”

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.

A language model drew the claims from the paper on 2026-10-06, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-06 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Cited sources are checked with a language model’s help (gpt-6-sol).

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.
