#945 Interference of Nutrient/Oxygen Availability with mTOR Activation and Inhibition in Lung Carcinoids: A Tissue and Cellular Study
Introduction: MTOR is capable of coupling cellular nutrient sensing to metabolic homeostasis. However, little is known of the interactions between cancer‐specific metabolic pathways and profiles of responsiveness to mTOR inhibition in neuroendocrine tumors.

#1810 FOXM1 Is Strongly Associated with Cell Proliferation and Is Not Influenced by Metabolic Syndrome in GEP-NETS
Introduction: Gastro-entero-pancreatic neuroendocrine tumors(GEP-NETs) and metabolic syndrome(MS) are both increasing exponentially. MS has been associated with several non NET cancers.

#1945 Metabolic Adaptation to Anti-Angiogenic Therapy
Introduction: Although anti-angiogenic inhibition (AI) therapy has demonstrable efficacy in mouse models of cancer and in certain types of human cancer, responses are typically transitory, followed by resumption of malignant progression that limits survival benefit. Unconventional modes of evasive/adaptive resistance underlay the eventual failures of anti-angiogenic therapy. Functionally established resistance mechanisms include revascularization mediated by alternative pro-angiogenic signals, protection by peri-vascular macrophages and monocytes to induce an immunosuppressive microenvironment, and normal vessel cooption via heightened local invasion and distant metastasis. All three mechanisms have been documented in the prototypical RIP-Tag2 mouse model of multistep tumorigenesis, in which the angiogenic switch is a discrete step in the pathway to invasive pancreatic neuroendocrine cancer.

#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.

#1166 mTOR Pathway Inhibition Sensitizes Insulinoma Cells to Streptozotocin Induced Apoptosis
Introduction: Pancreatic neuroendocrine tumors (pNETs) are generally chemoresistants probably due to low proliferation rate and defects in apoptotic pathway. Targeted therapies are new encouraging options for pNETs however; clinical trials show limited objective response. Combination of chemotherapy and targeted therapy could be a new solution in therapeutic care. Streptozotocin (STZ) is the 1st line of therapy for unresectable pNETs.

#453 Activation of Hedgehog Pathway in Neuroendocrine Tumor
Introduction: Neuroendocrine tumors (NETs) are rare tumors and often follow an indolent course, especially the tumors of low-to-intermediate grade. The genetic etiology of sporadic NET is largely unknown. It is well-known that a significant number of patients with NETs may have harbored the slow-growing lesions since very a young age, suggesting it could result from alterations of pathways involved in development. Hedgehog (Hh) signaling has been found to be important in embryonic patterning, stem cell maintenance and tissue repair; and is normally silenced in most mature adult tissue. However, it frequently undergoes gain-of-function mutations or reactivation due to ligand overproduction and has been linked to the etiology of a variety of tumors.

#726 Expression and Phosphorilation of mTOR Pathway and Antitumor Activity of mTOR Inhibitors in Neuroendocrine Tumors
Introduction: The mammalian target of rapamycin (mTOR) is a protein kinase involved in the control of cancer cell metabolism, growth and proliferation. The mTOR pathway has attracted broad scientific and clinical interest, particularly in light of the ongoing clinical cancer trials with mTOR inhibitors in pts with neuroendocrine tumors (NETs). To identify the best candidates for treatment with mTOR inhibitors is challenging.

#1362 Targeting Tumor Metabolism in NETs: A Novel Mechanism of Action of the Somatostatin Analog Lanreotide
Introduction: One of the hallmarks of cancer is reprogramming of energy metabolism, characterized by a shift to aerobic glycolysis. This metabolic switch provides cancer cells appropriate conditions required for enhanced proliferation and survival. The effects of somatostatin on tumor metabolism had not been determined yet.
