Why are dabrafenib and trametinib used together?

Why are dabrafenib and trametinib used together?

The combination of dabrafenib and trametinib blocks the signaling pathway of the abnormal BRAF molecules. This action slows or stops the out-of-control cell growth: Dabrafenib targets the V600E-mutated BRAF molecule to block its signaling.

What is the function of MEK?

MEK is a key enzyme in the Ras/Raf/MEK/ERK signal transduction pathway and mediates cellular responses to different growth signals. This pathway is frequently deregulated in cancer, which makes these enzymes a candiate target for pharmacological antineoplastic treatment.
