Abstract

The transcription factor and tumor suppressor protein p53 is the most frequently mutated and inactivated gene in cancer. Mutations in p53 result in deregulated cell proliferation and genomic instability, both hallmarks of cancer. There are currently no therapies available that directly target mutant p53 to rescue wild-type function. In this study, we identify covalent compsounds that selectively react with the p53 somatic mutant cysteine Y220C and restore wild-type thermal stability. Significance: The tumor suppressor p53 is the most mutated gene in cancer, and yet no therapeutics to date directly target the mutated protein to rescue wild-type function. In this study, we identify the first allele-specific compound that selectively reacts with the cysteine p53 Y220C to rescue wild-type thermal stability and gene activation.

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.
