First, we classified tumours with high and low BAZ2A levels (83 primary PCas for each group, BAZ2Ahigh, the top 25% of PCas with the highest BAZ2A expression; BAZ2Alow, the top 25% of PCas with the lowest BAZ2A expression) and identified 409 genes that were significantly down-regulated in BAZ2Ahigh compared with BAZ2Alow tumours (Fig 6A and B). This evidence concerns the gene BAZ2A and neoplasm.
