#801 Normal Gastrointestinal Neuroendocrine Cells Lack E-cadherin
Introduction: E-cadherin plays a crucial role in the adhesion between epithelial cells and thus epithelial integrity. Moreover, germ line mutations in the E-cadherin gene (CDH1) causing loss of E-cadherin function (adhesion) leads to hereditary gastric cancer of the diffuse type, according to Laurén. Even sporadic gastric carcinomas of the diffuse type often lose E-cadherin expression due to mutations. Lack of E-cadherin has been recorded at an early phase in such carcinomas.

#2256 Assessment of the Serum Levels of the Soluble Vascular Cellular Adhesion Molecule-1 (sVCAM-1) in Patients with Neuroendocrine Neoplasms
Introduction: Tumor growth and the ability to metastasize is a multistage process involving interactions between cancer cells and the vascular endothelium. These interactions have been reported to be mediated by various molecules including sVCAM-1. We have previously shown elevated serum concentration of sVCAM-1 in 82 neuroendocrine neoplasms (NEN) compared to controls. Here, we present results of the extension of the previous study.

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

#2199 Systematic Evaluation of the Immune Microenvironment of Neuroendocrine Tumors (NET)
Introduction: Immunotherapy is being explored in many tumour types with encouraging results, but
its role in the management of NET is yet to be defined.

#894 The Effects of cAMP in Different Neuroendocrine Tumorous Cells: The Role of Epac and PKA in Cell Proliferation and Cell Adhesion
Introduction: cAMP is implicated in the inhibition or stimulation of proliferation depending on cell type. Although the effects exerted by cAMP were initially attributed to the PKA activation, two cAMP-activated guanine nucleotide exchange (Epac1/2) have been later identified as cAMP targets.

#770 The Axon Guidance Molecules Slit2 and Robo Control Motility and Growth of Pancreatic Neuroendocrine Tumor Cells
Introduction: Dense vascularization and high frequency of metastasis in pancreatic neuroendocrine tumors (pNET) suggest a central role for the interaction of tumor cells and vessels. Slit2 and its receptors Robo1 and Robo4 act as guidance cues in neurogenesis, angiogenesis and epithelial morphogenesis, and hence represent attractive candidate regulators at the tumor cell/stroma interface.

#618 Angiogenic Characteristics of Radiological Hypervascular Liver Tumors (NET, Hepatocellular Carcinoma) and Hypovascular Colorectal Liver Metastases and Their Microenvironment.
Introduction: Tumor and microenvironment are important for tumor progression. Liver tumors can be hypervascular or hypovascular during the arterial phase of cross-sectional imaging.

#898 Evaluation of Tumor Response to Targeted Therapies in Precision-Cut Slices of Human Pancreatic Neuroendocrine Tumors
Introduction: Patients with PNET might benefit from new therapeutic approaches acting on the mTOR signaling pathway. Culture of precision-cut slices could allow testing these molecules in human tumors, allowing personalized treatments.
