Synergistic Inhibition Of Mekerk And Braf V600e With

Background and aims The activating mutation BRAF V600E is a frequent genetic event in papillary thyroid carcinomas (PTC). Mutation BRAF V600E is associated with the loss of a sodium/iodine symporter (NIS), and subsequent radioiodide-refractory (RAI) metastatic disease. Use of BRAF V600E inhibitors could partly restore NIS expression and Iodide uptake by inhibition of mitogen-activated
