C-Myc promotes lymphatic metastasis of pancreatic neuroendocrine tumor through VEGFC upregulation.

ABSTRACT: Pancreatic neuroendocrine tumor (pNET) is a pancreatic neoplasm with neuroendocrine differentiation. pNET in early stage can be treated with surgical resection with long-term survival, whereas the prognosis of pNET with locoregional or distant metastasis is relatively poor. Lymphangiogenesis is essential for tumor metastasis via the lymphatic system and may overhead distant metastasis. c-Myc overexpression is involved in tumorigenesis. The role of c-Myc in lymphangiogenesis is unclear. In this study, we evaluated the mechanism and effect of c-Myc on lymphangiogenesis of pNET via interaction of lymphatic endothelial cells (LECs) and pNET cells. Lymph node metastasis was evaluated in pNET xenograft mice. Potential target agents to inhibit lymph node metastasis were evaluated in an animal mod
