Abstract
The BRAF inhibitor (BRAFi) vemurafenib improves survival of patients with melanoma with BRAFV600E mutations. However, effects of sustained BRAFis on BRAFi-resistant melanomas with dual mutations in BRAF and NRAS are not well characterized. Jandova and Wondrak (2021) report that vemurafenib selectively enhances expression of genes involved in the epithelial-to-mesenchymal transition in BRAFV600E/NRASQ61K melanoma cells, paradoxically promoting tumor growth and metastasis in mice. This preclinical study provides compelling reasons to be cautious in the use of BRAFis in patients with NRAS-driven melanoma.Entities:
