Immunohistological staining for the expressions of HIF-1α, PHD3, and Siah2 in surgical specimens from PDAC and HCC patients. a HIF-1α was positively stained in the nuclei of cancer cells in HCC specimens, but was negatively or extremely rarely stained in the PDAC specimens, and a semiquantitative analysis showed a significant difference between the groups (p < 0.05). b PHD3 was positively stained in many cancer cells in the PDAC specimens, but was negatively or weakly stained in the HCC specimens (p < 0.001). c The expression of Siah2 was negative or weak in both the PDAC and HCC specimens, but the semiquantitative analysis showed a significantly higher expression in the HCC specimens (p < 0.05)
