This PDF file includes:

  • Fig. S1. AR cells are resistant to multiple MEK and BRAF inhibitors.
  • Fig. S2. The ability of AZD6244 and AZ628 to inhibit ERK phosphorylation is attenuated in AR cells.
  • Fig. S3. CRAF is not amplified in AR cells.
  • Fig. S4. Knockdown of BRAF, but not CRAF, restores the ability of AZD6244 to inhibit ERK phosphorylation.
  • Fig. S5. Resistance caused by overexpression of V600E BRAF can be overcome by combined MEK and BRAF inhibition.
  • Fig. S6. Enhanced inhibition of ERK phosphorylation underlies the increased sensitivity of parental cells to combination treatment with AZD6244 and AZ628.
  • Table S1. BRAF amplification in BRAF-mutant human colorectal cancer.
