Given that tumor aggressiveness has been linked with EMT ([51], reviewed in [52]) we examined the expression of MYB in a publically available microarray dataset series of human breast tumors [50] and observed that MYB expression was generally high in Luminal A and Normal-like tumors but dramatically lower in Basal and Her2 + tumors (Figure 5B). The gene discussed is MYB; the disease is neoplasm.
