Finally, levels of fibrin (the terminal protein of the coagulation cascade) were also positively correlated with HIF2α (but not HIF1α) expression in breast (RS=0.22; P<0.001, Fig. 6B) and pancreatic tumours (RS=0.33; P<0.01, Fig. 6C). The gene discussed is HIF1A; the disease is pancreatic neoplasm.
