BACKGROUND:Pancreatic cancer is 1 of the most common and poorly treated tumors. In search of new therapeutic approaches, the oxygen sensors prolyl hydroxylases (PHD) are potential targets. PHD2 is considered the key oxygen sensor‐regulating hypoxia‐inducible factor (HIF). Currently, there is conflicting evidence regarding the exact role of PHD2 in tumorigenesis. The objective of this study was to...
We investigated the expression pattern and clinical significance of the costimulatory ligands B7-1, B7-2, B7-H1, and B7-DC, and their counter-receptors CTLA-4 and PD-1 in pancreatic cancer. Gene expression of all examined costimulatory molecules was significantly upregulated in pancreatic cancer tissues. B7-1, B7-2, B7-H1, and B7-DC protein was detectable in pancreatic cancer cells. Only the expression...
