Consistently, western blot analyses of three available normal pancreases (NPs) and seven PDAC tissues for establishing patient‐derived xenograft (PDX) tumours indicated that while none of the three NP expressed DDX5, all seven of the PDAC tumours expressed DDX5 from high (PDX14244) to low (PDX12872) levels (Figure 5A). The gene discussed is DDX5; the disease is neoplasm.
