Slug represents an important regulator of E-cadherin expression in neuroendocrine tumor cells of the pancreas Abstract #110

Introduction: Neuroendocrine tumors of the pancreas form an inhomogenous group of epithelial neoplasms. They differ from other types of pancreatic cancers by showing an extended survival of patients, which is due to a mostly slow proliferation rate of the tumor. However, some of these neuroendocrine tumors are characterized by an early onset of metastases, which cannot be predicted by any available method. The epithelial to mesenchymal transition (EMT) represents a central part of cell migration and metastasis. During EMT, cells loosen their cellular contacts, leave the tissue, and become migrating single cells. One of the integral compounds of cell adhesion represents the E-cadherin adhesion module, which contains mostly E-cadherin and several catenins. A loss of this adhesion module is associated with tumor progression, migration and metastasis in many types of cancer.
Aim(s): We are interested in factors which are responsible for reduction of cellular adhesion and also in metastasis of neuroendocrine tumors.
Materials and methods: We analyzed 85 samples of surgically resected neuroendocrine tumors of the pancreas for E-cadherin and Slug expression. We investigated the relation of E-cadherin and Slug in the neuroendocrine tumor cell line BON-1.

Introduction: Pancreatic neuroendocrine tumors (PNET) remain an unmet clinical need. In this study, we show that targeting both nicotinamide phosphoribosyltransferase (NAMPT) and p21-activated kinase 4 (PAK4) could become a synthetic lethal strategy for PNET.

#2685 Apatinib Inhibits Tumor Growth and Angiogenesis in PNET Models
Introduction: Angiogenesis has a pivotal role in the growth and metastasis of pancreatic neuroendocrine tumors (PNETs). Apatinib inhibits angiogenesis as a highly selective KDR inhibitor and has been used to treat advanced gastric cancer and malignancies in clinical settings. However, the efficacy of apatinib in PNETs remains unclear.
