Hyperactivation of extracellular signal-regulated kinase (ERK) by RAS-mediated signaling or inhibition of dual specificity phosphatase 6 (DUSP6) is associated with toxicity in lung adenocarcinoma cells with mutations in KRAS or EGFR
Abstract:We recently described the synthetic lethality that results when mutant KRAS and mutant EGFR are coexpressed in human lung adenocarcinoma (LUAD) cells, revealing the biological basis for the mutual exclusivity of KRAS and EGFR mutations in lung cancers. We have now further defined the biochemical events responsible for the toxic effects of signaling through the RAS pathway. By combining pharmacological and genetic approaches, we have developed multiple lines of evidence that signaling through extracellular sign… Show more
