RAF1 and colorectal carcinoma: The anti-proliferative effects of LY3009120 in KRASmut CRC cell lines phenocopied molecular inhibition of RAF isoforms by simultaneous siRNA-mediated knockdown of ARAF, BRAF and CRAF. Additionally, LY3009120 displayed significant activity in in vivo BRAFmut and KRASmut CRC xenograft models.
