Curiously, there were poor correlations between the levels of DHH and luminal markers (Pearson coefficient=0.025 or −0.054 for KRT8 or KRT18 with DHH) or basal markers (Pearson coefficient=0.001 or −0.017 for KRT5 or TP63 with DHH) in tumor samples (Table S1B), indicating that DHH expression is induced in a tumor context-dependent manner. Here, KRT5 is linked to neoplasm.
