High expression of CEACAM1 in the melanoma samples correlated with high cytoplasmic/nuclear Twist (φ = 0.20, p = 0.049) and also CEACAM1 staining in a certain area of an individual melanoma often correlated with cytoplasmic/nuclear TWIST staining intensity in the same area (serial sections, e.g. Supplementary Fig. 7). The gene discussed is CEACAM1; the disease is melanoma.
