The invention discloses application of p38 gamma in preparation of a pancreatic cancer prognosis diagnostic reagent. The inventor finds that expression of p38 gamma in cancer tissues of a pancreatic cancer patient is remarkably higher than that of p38 gamma in normal tissues, the expression level of p38 gamma is gradually increased along with disease progression, and the high expression of p38 gamma is related to adverse prognosis of the patient. A pancreatic duct adenocarcinoma animal model K-RasG12D-p53R172H-Pdx-Cre (KPC) is constructed as a control group for research. A pancreatic ductal epithelial cell p38 gamma knockout pancreatic cancer animal model (KPC-p38 gamma-KO) is constructed as an experimental group by applying a Cre/LoxP technology. The p38 gamma knockout is found to be capable of remarkably reducing the size of a tumor and prolonging the lifetime of KPC mice. The median survival time of the mice in the KPC group is 160 days, most KPC-p38 gamma-KO mice still survive in the statistical time, and the median survival time is longer than 300 days. A further experimental result shows that high expression of p38 gamma can promote invasion and metastasis of a pancreatic cancer. Therefore, p38 gamma can well determine the risk and prognosis of the pancreatic cancer.

The invention discloses application of PLD1 as a molecular marker for evaluating sensitivity of tumor patients to chemotherapeutic drugs. The invention finds that the expression level of PLD1 in pancreatic ductal adenocarcinoma is related to the sensitivity to gemcitabine, the expression of PLD1 in pancreatic cancer tumor cell nucleuses is related to the differentiation degree and T staging of tumors, and the total lifetime of patients with high expression of PLD1 in cancer ductal cell nucleuses is short, which indicates that the patients with high expression of PLD1 in pancreatic cancer ductal cells are related to postoperative recurrence and metastasis, and the patients with high expression of PLD1 in pancreatic cancer ductal cells are related to postoperative recurrence and metastasis.
