Expression of neuropeptide Y and its receptors Y1 and Y2 in pancreatic intraepithelial neoplasia and invasive pancreatic cancer in a transgenic mouse model and human samples of pancreatic cancer.
Pancreatic ductal adenocarcinoma (PDAC) is among the most dismal of human malignancies. Neuropeptides have shown to be implicated in angiogenesis, tumor growth, and formation of distant metastases in various solid tumors. In the present study, we used a genetically engineered mouse model of pancreatic cancer to evaluate the impact of neuropeptide Y (NPY) and its receptors 1 (Y1) and 2 (Y2) in preneoplastic lesions and pancreatic cancer as a potential target with antiproliferative properties. In addition, human PDAC tissue was analyzed.. By interbreeding conditional LsL-Trp53. NPY and Y1 expressions were detected in human and murine pancreatic samples, but expression levels were similar in neoplastic and non-neoplastic tissue. Y2 revealed a significant increase of expression in the transgenic mouse model in PanIN lesions and pancreatic cancer compared to control. This holds also true for human samples of pancreatic cancer. Immunohistochemistry of Y2 in murine and human samples of PanINs and pancreatic carcinoma revealed an increased expression in PanIN lesions and pancreatic cancer.. Y2 is strongly overexpressed in pancreatic cancer and may modulate angiogenesis.
