#874 The pan-TRK Inhibitor GNF5837 Inhibits Cell Viability and Akt and MAPK Signaling in Human Neuroendocrine GOT1 Tumor Cells
Introduction: The tropomyosin receptor kinase family (TRKA, TRKB, TRKC) effects tumor cell growth in various models. Recent preclinical studies in neuroendocrine carcinoma of the lung cell lines have shown that Trk receptors might be a therapeutic target for neuroendocrine neoplasias.

#739 Aspirin Inhibits Cell Viability and mTOR Signalling in Neuroendocrine Tumor Cells
Introduction: Patients with multiple endocrine neoplasia (MEN) type 1 develop pancreatic NETs as well as thymic and bronchus carcinoids. Aspirin has been reported to inhibit mTOR signalling and exhibit antitumoral activity in colorectal cancer cells. So far, no data with aspirin on NETs have been published.

#1999 Study of Cell Cycle Protein Expression Pattern in Bronchial Carcinoids: A New Potential Target for Medical Therapy?
Introduction: Bronchial Carcinoids (BCs) are rare neuroendocrine neoplasms arising from respiratory epithelium. The only effective treatment option is surgery, but its efficacy is frequently limited by metastatic spread. Everolimus prolongs progression free survival but patients may develop resistance. Previous studies demonstrated that Everolimus reduces viability of NCI-H720 cells (Atypical Carcinoid) but not of NCI-H727 cells (Typical Carcinoid). Everolimus decreases Ciclyn D1 protein levels in both cell lines but NCI-H727 cells survive, indicating a derangement in cell cycle control.

#1089 Role of TGF beta-1 in Regulating Pancreatic Neuroendocrine Tumor Cell Viability
Introduction: Neuroendocrine tumors (NETs) are heterogeneous neoplasms arising from neuroendocrine cells spread in the respiratory and gastro-entero-pancreatic epithelium. The role of transforming growth factor beta-1 (TGF b-1) in NET biology is largely unknown. TGF b-1 signaling pathway is tumor suppressive in most non-transformed epithelial cell lines. In contrast, many human carcinomas are refractory to the growth–inhibitory effects of TGF b-1.

#1476 Efficacy of Everolimus and Somatostatin Analogs as Single Agents or in Combination in Human Pancreatic Neuroendocrine Tumors Primary Cultures
Introduction: Among the therapeutic options available for the treatment of neuroendocrine tumors, one targeted therapy, everolimus (RAD) has been approved for advanced progressive pancreatic neuroendocrine tumors (pNETs). It improve progression free survival but is not curative. Alterations of the PI3K/Akt/mTOR pathway in pNETs have given the rational for the use of this signaling pathway inhibitors.

#387 Combined Blockade of Several Signalling Pathways Shows Marked Anti-Tumor Potential in Two Novel Mouse Phaeochromocytoma Cell Lines
Introduction: The current study explores novel targeted therapies for malignant pheochromocytomas (PCCs) and paragangliomas, utilizing a more benign (MPC) and a more malignant (MTT) PCC cell line. We have previously shown that the dual PI3K/mTORC1 inhibitor NVP-BEZ235 significantly reduced MPC and MTT cell viability, but increased ERK signalling.

#1036 Abrogation of Autophagy by Chloroquine in Neuroendocrine Tumor Cells Treated with mTOR Inhibitors Induces Apoptosis, While Reduction of Cell Proliferation is Due to a Chloroquine, Autophagy Unrelated, Lysosomal Effect
Introduction: The therapy options for patients with advanced NETs are limited. The mTOR inhibitors (mTORi), Torin1 and NVP-BEZ235, are known to suppress cell proliferation in NETs. However, cancer cells may use mTORi-induced autophagy to prolong survival, evading the anti-cancer effect. Chloroquine (CQ) and hydroxychloroquine (HCQ) have been shown to inhibit autophagy.

#265 A Novel PKCßII Inhibitor Induces Antiproliferative Effects in Human Pancreatic Neuroendocrine Tumor Cells
Introduction: Deregulation of the protein kinase C (PKC) signaling pathway has been implicated in tumor progression.

#266 Everolimus Reduces Cell Viability in Selected Human Medullary Thyroid Carcinoma Primary Cultures
Introduction: It has been demonstrated that everolimus, an mTOR inhibitor, has a potent anti-proliferative effect in a human Medullary Thyroid Carcinoma (MTC) cell line, TT, and in two human MTC primary cultures.

#430 mTOR Inhibitors Hamper Cell Viability in Selected Human Medullary Thyroid Carcinoma Primary Cultures
Introduction: It has been demonstrated that mTOR inhibitors have potent anti-proliferative effects in a human Medullary Thyroid Carcinoma (MTC) cell line. We here explore the possible role of mTOR inhibitors, Everolimus and BEZ235 (which also inhibits the PI3K pathway) on the effects of Insulin-like Growth Factor-1 (IGF-1) in human MTC primary cultures.
