Abstract

The transcription factor NRF2 is a master regulator of the cellular antioxidant response, and it is often genetically activated in non-small-cell lung cancers (NSCLCs) by, for instance, mutations in the negative regulator KEAP1. While direct pharmacological inhibition of NRF2 has proven challenging, its aberrant activation rewires biochemical networks in cancer cells that may create special vulnerabilities. Here, we use chemical proteomics to map druggable proteins that are selectively expressed in KEAP1-mutant NSCLC cells. Principal among these is NR0B1, an atypical orphan nuclear receptor that we show engages in a multimeric protein complex to regulate the transcriptional output of KEAP1-mutant NSCLC cells. We further identify small molecules that covalently target a conserved cysteine within the NR0B1 protein interaction domain, and we demonstrate that these compounds disrupt NR0B1 complexes and impair the anchorage-independent growth of KEAP1-mutant cancer cells. Our findings designate NR0B1 as a druggable transcriptional regulator that supports NRF2-dependent lung cancers.

  • Compounds were discovered that bind a ligandable cysteine on NR0B1, which is regulated by NRF2, a KEAP1 substrate.

    “The authors discovered compounds that bind to a ligandable cysteine on the nuclear receptor NR0B1, which is regulated by NRF2, a substrate of KEAP1 (ref.181).”

  • Cysteine reactivity and ligandable sites were mapped in mutant KEAP1 and compared with wild-type KEAP1 NSCLC lines.

    “cysteine reactivity and ligandable sites were mapped in mutant Kelch-like ECH-associated protein 1 (KEAP1) and compared with those in wild-type KEAP1 NSCLC lines.”

    From Advances in covalent drug discovery (2022) · cites this paper as [181]

  • The authors observed limited overlap of enantioprobe targets with proteins that demonstrated ligandability in previous chemical proteomic studies using cysteine- or lysine-reactive electrophilic fragments.

    “We finally observed limited overlap of enantioprobe targets with proteins that demonstrated ligandability in previous chemical proteomic studies using cysteine-26,27 or lysine-reactive28 electrophilic fragments (Fig. 3b)”

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.
