BRAF and colorectal carcinoma: Next, to assess whether, as found in mice (Figure 1), ZEB1 expression affects the survival of patients with BRAF-mutant CRC, 38 patients with metastatic CRC harboring BRAFV600E were segregated into 2 cohorts based on ZEB1 expression above or below the upper tertile (n = 11 with high ZEB1 expression [ZEB1-high] and 27 with low ZEB1 expression [ZEB1-low]).
