COT/MAP3K8 drives resistance to RAF inhibition through MAP kinase pathway reactivation
[Paper-level Aggregated] PMCID: PMC3058384
Evidence Type(s): Oncogenic, Predictive, Functional
Justification: Oncogenic: The B-RAFV600E mutation is described as an oncogenic mutation found in a significant percentage of malignant melanomas, indicating its role in cancer development. Predictive: The B-RAFV600E mutation predicts a dependency on the MAPK signaling cascade in melanoma, which is supported by the success of RAF and MEK inhibitors in clinical trials. Functional: The study functionally interrogates resistance mechanisms to a selective RAF kinase inhibitor in B-RAFV600E cell lines, identifying MAP3K8 as a factor driving resistance, demonstrating the functional implications of the variant.
