A proteomic and phosphoproteomic landscape of KRAS mutant cancers identifies combination therapies


ABSTRACT: KRAS mutant cancers, which feature the activation of multiple phosphorylation signaling pathways, remain a major challenge for cancer therapy. This study provides a landscape of the proteomics and phosphoproteomics of KRAS mutant cancers by analyzing different KRAS mutant human cancer cell lines across different tissues types. By integrating multi-omics analysis, we identify different robust subsets, which recapitulate the histological, pathological and prognostic features of human cancers.

KRAS mutant cancer, characterized by the activation of a plethora of phosphorylation signaling pathways, remains a major challenge for cancer therapy. Despite recent advancements, a comprehensive profile of the proteome and phosphoproteome is lacking. This study provides a proteomic and phosphoproteomic landscape of 43 KRAS mutant cancer cell lines across different tissue origins. By integrating transcriptomics, proteomics, and phosphoproteomics, we identify three subsets with distinct biologica  ...[more]
