Abstract

Combinatorial inhibition of effector and feedback pathways is a promising treatment strategy for KRAS mutant cancers. However, the particular pathways that should be targeted to optimize therapeutic responses are unclear. Using CRISPR/Cas9, we systematically mapped the pathways whose inhibition cooperates with drugs targeting the KRAS effectors MEK, ERK, and PI3K. By performing 70 screens in models of KRAS mutant colorectal, lung, ovarian, and pancreas cancers, we uncovered universal and tissue-specific sensitizing combinations involving inhibitors of cell cycle, metabolism, growth signaling, chromatin regulation, and transcription. Furthermore, these screens revealed secondary genetic modifiers of sensitivity, yielding a SRC inhibitor-based combination therapy for KRAS/PIK3CA double-mutant colorectal cancers (CRCs) with clinical potential. Surprisingly, acquired resistance to combinations of growth signaling pathway inhibitors develops rapidly following treatment, but by targeting signaling feedback or apoptotic priming, it is possible to construct three-drug combinations that greatly delay its emergence.

  • Drug combinations of MEK and SRC inhibitors have been carried out in vitro using various types of cancer cell lines and to a less degree in vivo using mouse models, where enhanced anti-cancer effects have been reported.

    “Notably, exploration of drug combinations of MEK and SRC inhibitors have been carried out in vitro using various types of cancer cell lines and to a less degree in vivo using mouse models, where enhanced anti-cancer effects have been reported [53–57].”
  • Adaptive resistance, in which the inhibited pathway is reactivated due to induction of RTKs/RTK ligand genes, is a common form of intrinsic resistance.

    “Adaptive resistance (termed “rebound” by some investigators), in which the inhibited pathway is reactivated due to induction of RTKs/RTK ligand genes, is a common form of intrinsic resistance (Anderson et al., 2017; Duncan et al., 2012; Lin et al., 2015; Manchado et al., 2016; Nazarian et al., 2010; Sun et al., 2014; Zawistowski et al., 2017).”

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.
