RAF inhibitors

Thursday 4 March 2010

Tumours with mutant BRAF are dependent on the RAF-MEK-ERK signalling pathway for their growth.

ATP-competitive RAF inhibitors inhibit ERK signalling in cells with mutant BRAF, but unexpectedly enhance signalling in cells with wild-type BRAF.

RAF inhibitors do not inhibit ERK signalling in cells that coexpress BRAF-V600E and mutant RAS. (20179705)
