Nat Commun 8:15262. doi: 10.1038/ncomms15262 PMID: 28497782
Objective: To investigate the contribution of Raf genes in tumor progression, from the onset of benign tumors to malignant tumor maintenance, in NRAS-induced mouse melanoma models
Summary: BRAF expression is required for ERK activation and nevi development, demonstrating a critical role in the early stages of NRAS-driven melanoma. After melanoma formation, single BRAF or CRAF ablation is not sufficient to block tumor growth, showing redundant functions for RAF kinases. Proliferation of resistant cells emerging in the absence of BRAF and CRAF remains dependent on ARAF-mediated ERK activation.
