Genes involved in migration or epithelial to mesenchymal transition (EMT) (ITGA2B, COL4A5, FSTL3, COL8A2, FN1, BMP1, TIMP1, FOXQ1, ITGA3, POSTN, CD63) correlated with MAPT expression positively or negatively depending on the cancer type (Fig. 1b). The gene discussed is COL4A5; the disease is cancer.
