Furthermore, KM survival analysis shows that PHD2 protein oxidation in pancreatic cancer tissue is closely related to the survival time of pancreatic cancer patients, and the survival time of patients with lower levels of PHD2 protein oxidation is significantly lower than those with higher PHD2 protein oxidation (8.25 months VS 22.25 months, P = 0.001) (Fig. 6E). The gene discussed is EGLN1; the disease is pancreatic neoplasm.
