#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.

#1202 Role of Amplifications in the PIK3/Akt/mTOR-Pathway in Neuroendocrine Tumors of the Small Intestine
Introduction: Amplifications in the PIK3/Akt/mTOR pathway can lead to increased proliferation and reduced apoptosis, resulting in the development of various cancers. Recently, amplifications of Akt1/2, PDGFRα/β and mTOR in small intestine neuroendocrine tumors (siNET) have been shown.

#2008 Preliminary Evaluation of Influence of Different Targeted Drugs of Vascular Endothelial Growth Factor Signaling Pathway on the Proliferation of Neuroendocrine Neoplasm Cell Lines
Introduction: Sunitinib and bevacizumab are intracellular and extracellular inhibitor of vascular endothelial growth factor(VEGF) pathway respectively, the influence of both of which on the proliferation of neuroendocrine neoplasm (NEN) cell lines in vitro was not known yet.

#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.

#2781 Case Report: Whole Exon Sequencing of Primary Lesion and Metastatic Liver Lesion in Pancreatic Neuroendocrine Tumor
Introduction: Pancreatic neuroendocrine neoplasms(NENs) are classified into neuroendocrine tumors (NET) G1, G2, G3, and neuroendocrine carcinoma (NEC), which are different pathogenesis. The two kinds of tumors that occurs in the same lesion in one patient is very rare. We found high grade neuroendocrine neoplasms(NENG3) with a diameter of 0.1 cm in a patient with a pancreatic NETG2 (1.7 cm in diameter). The cells were significant atypia with Ki67 index of 60%, focal necrosis, while metastatic nodules in the liver (12, 0.1-1.1 cm in diameter) were all high grade NENG3.
