#198 Novel Insights in Octreotide Effects on Human Neuroendocrine Cell Line CNDT2.5
Introduction: Octreotide, the first synthetic somatostatin analog available for clinical use, efficiently binds somatostatin receptors (SSRs) 2 and 5 and may transduce its effects by using SSRs.

#1001 Forkheadbox Proteins as Novel Drug Targets in Gastroenteropancreatic Neuroendocrine Tumor Disease: Inhibition of FoxM1 Exerts Antiproliferative Effects in GEP-NEN Cell Lines
Introduction: Forkheadbox proteins (Fox proteins) are transcriptions factors. They are highly conserved key players in a large number of cellular processes. Fox proteins have been described as acting as both tumor suppressors and oncogenes. Most notably, they operate in the context of the majority of cancer-related pathways. Information about the fuunction of these proteins in gastroenteropancreatic neuroendocrine neoplasias is scant.

#174 Loss of Expression of the DNA Mismatch Repair Proteins MLH1 and MSH2 is Rare in Pancreatic and Small Intestinal Neuroendocrine Tumors
Introduction: Loss of expression of the DNA mismatch repair (MMR) proteins MLH1 and MSH2, which is known to correlate strongly with MSI, has not been well studied in pancreatic or small intestinal NETs.

#175 The Immunohistochemical (IHC) Expression and Prognostic Value of ER, PR, and HER2/neu in Pancreatic and Small Intestinal Neuroendocrine Tumors
Introduction: There has been limited study of ER and PR expression in gastrointestinal neuroendocrine tumors (GINETs) and data on HER2/neu overexpression in GINETS has been conflicting.

#62 Genome-wide DNA methylation profiling of pancreatic neuroendocrine tumors identifies distinct methylation profiles and differentially methylated gene promoter regions associated with low, medium and high grade tumors
Introduction: Integration of genetics and epigenetics has emerged as a powerful approach to studying cellular differentiation (Mikkelsen et al, 2009) and tumorigenesis (Shen et al, 2007). The study of DNA methylation is of particular importance in cancer, as causal involvement has been demonstrated and it is the most stable of all epigenetic modifications, making it a desirable marker for both early detection and treatment of tumors. Hypermethylation of CpG sites in gene promoter regions leads to decreased gene expression; if such a gene is a tumor suppressor, this leads to carcinogenesis. To date, there have been no studies of genome-wide DNA methylation profiling of NETs. This study sets out to determine the DNA methylation profiles of low, intermediate and high grade pancreatic NET liver metastases with the intention of identifying dysregulated biological pathways in the development of these tumors. A protocol for the analysis formalin-fixed paraffin embedded tissue (FFPE) has also been developed in order to study these tumors in significant numbers following this pilot study.

#167 Localization of Sporadic Neuroendocrine Tumors by Gene expression Analysis of Their Metastases
Introduction: Primary neuroendocrine tumors (NETs) are rare and often difficult to detect, leading to diagnosis late in their development. Cases in which the primary cannot be located are denoted as CUP-Syndrome.

#462 Genome-Wide Expression Profiling Reveals Downregulation of OTP and CD44 and Upregulation of RET as Indicators of Poor Prognosis in Lung Carcinoids
Introduction: Lung carcinoids comprise a heterogeneous group of neuroendocrine tumors. Only few parameters have been identified that correlated with poor disease outcome, including 11q22-q25 deletions. New biomarkers are required to further improve diagnosis and prediction of prognosis.

#654 Identification of Signaling Pathways Involved in Lung Carcinoid Progression Using Gene Expression Profiling
Introduction: Lung carcinoids are well-differentiated neuroendocrine tumors (NETs) usually associated with a favorable prognosis. Mechanisms underlying progression are poorly understood.
