GAS/CCK-2R and function of its antagonists in treatment of the pancreatic cancer / 国际外科学杂志

ABSTRACT

Studies in recent years revel that there is a close relationship between gastrin/cholecystokinin-2 receptors (GAS/CCK-2R) and pancreatic cancer. CCK-2R is widely distributed in human body, but not in normal exocrine pancreas. However, CCK-2R is abnormally expressed in pancreatic carcinoma. The abnormal expression of CCK-2R in pancreatic tissues leads to the abnormal protein expression and activation, changes in acinar cells' morphology and phenotype and an increase in the sensitivity to carcinogenic substances. And some GAS/CCK-2R antagonists can be used for the early and late treatment of pancreatic cancer.
