DAB2 expression had significant positive correlations with mesenchymal markers (ZEB2, TGFβ1, SNAI2, ZEB1, FN1, MMP2, TWIST1 and MMP3) and CSC markers (CD44 and MYD88) in ovarian cancer cell lines (CCLE) and tissues (TCGA: RNA sequencing and microarray) (Fig. 5A). The gene discussed is FN1; the disease is ovarian cancer.
