Activating BRAF mutations, most commonly BRAFV600E, are a major oncogenic driver of many cancers. We explored whether BRAFV600E promotes radiation resistance and whether selectively targeting BRAFV600E with a BRAF inhibitor (vemurafenib, BRAFi) sensitizes BRAFV600E thyroid cancer cells to radiotherapy.
