High expression of CEACAM1 in the melanoma samples correlated with high LXN expression (φ = 0.37, p < 0.001) and also CEACAM1 staining in a certain area of an individual melanoma often correlated with LXN staining intensity in the same area (serial sections, e.g. Supplementary Fig. 5). The gene discussed is CEACAM1; the disease is melanoma.
