#1559 MTOR Controls an Epigenetic Program Leading to Autophagy and Cell Growth Control
Introduction: Makroautophagy represents an evolutionary highly conserved process involved in the clearance of proteins and organelles. The induction of this central cellular process is tightly connected with programs regulating cell growth control. While the cytoplasmic machinery that orchestrates autophagy is relatively well understood the key epigenetic events that initiate autophagy-related cell growth programs remain largely unknown.

#151 Rationale for combining mTOR with other targeted agents in the treatment of neuroendocrine tumors
Introduction: Advanced neuroendocrine tumors (NETs) are aggressive and incurable with standard treatment. Many cellular targets are being evaluated in this patient population, including mammalian target of rapamycin (mTOR), a kinase that is the central regulator of several signaling pathways related to cell growth, angiogenesis, and bioenergetics. Because mTOR serves as a neoplastic switch activated by many cancer-related mutations, mTOR inhibition may have broad efficacy across tumor types, including NETs. Somatostatin analogs (SSAs) have long been used to treat carcinoid symptoms in NET patients. The SSA octreotide long-acting release (LAR) demonstrated significant antitumor effects against advanced midgut NETs in the phase III PROMID study.

#820 ACTG2 Inhibits Growth and Is Epigenetically Repressed in Small Intestinal Neuroendocrine Tumors
Introduction: Small intestinal neuroendocrine tumors (SI-NETs) originate from the enterochromaffin cells in the ileum. Actin gamma smooth muscle 2 (ACTG2) is downregulated in lymph node metastases from SI-NETs. ACTG2 and microRNA-145 (miR-145) are aberrantly expressed in other cancers and ACTG2 can be induced by miRNA-145.

#119 Valproic acid induces apoptosis-mediated cell death of the ileal carcinoid cell line GOT1
Introduction: Downregulation of tumor suppressor genes, evasion from apoptosis, and reduced differentiation are hallmarks of cancer that can be due to abnormal epigenetic control. Histone deacetylase (HDAC) is an enzyme involved in the deacetylation of histone proteins, resulting in chromatin remodelling and altered gene transcription. HDAC inhibitors are emerging as useful anticancer drugs.

#969 Identification of Hypoxia Induced Epigenetic Changes in the Development of Pancreatic Neuroendocrine Tumors
Introduction: In VHL syndrome, pancreatic NETs develop through bi-allelic inactivation of VHL with subsequent HIF pathway activation. This also occurs in sporadic pancreatic NETs.

#219 Predictive Factors of Tumor Control in Patients with Well-differentiated Digestive Endocrine Carcinomas (WDEC) Treated with Lanreotide
Introduction: Somatostatin analogues (SSA) are indicated in the control of secretory symptoms of digestive endocrine tumors. The antiproliferative effect of SSA was recently demonstrated (Rinke et al, JCO 2009).

#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.

#970 Progression-Free Survival (PFS) and Tumor Growth with Lanreotide Autogel (LAN) in Patients (Pts) with Enteropancreatic NETs: Results from CLARINET, a Randomized, Double-Blind, Placebo (Pbo)-Controlled Study
Introduction: Prospective data on antiproliferative effects of somatostatin analogs are lacking in grade 2 and non-midgut tumors.

#86 Structure of complications in acromegalic patients at a single institute
Introduction: Acromegaly leads to reduced life expectancy, with an increase in the mortality rate. From several retrospective cohort studies, the predominant outcome is serum growth hormone (GH) concentration. Other factors associated with increased mortality include duration of symptoms prior to diagnosis, duration of disease, older age at diagnosis and the presence of cardiovascular disease, diabetes mellitus (DM) and hypertension at diagnosis.
