In the melanoma samples, ZEB1 level was positively related to CD4+ T cells (R = 0.338, p = 1.20e−13), CD8+ T cells (R = 0.203, p = 1.17e−5), macrophages (R = 0.152, p = 1.12e−03), dendritic cells (R = 0.008, p = 8.67e−1) and neutrophils (R = 0.528, p = 3.15e−34). This evidence concerns the gene ZEB1 and melanoma.
