Symbols correspond to the relative frequency within the subtype (o: very low frequencies [∼0%]; +++: very high frequencies; +/++: intermediate frequencies), and arrows indicate significant enrichment of subtype up- and down-regulated genes in most of the pathways of the given category. EMT, epithelial–mesenchymal transition; SC, stem cell; Wnt pw, Wnt pathway.
