#435 Olfactory Receptor 51E1 is a Novel Potential Tissue Biomarker for the Diagnosis and Prognosis of Small Intestine Neuroendocrine Tumors
Introduction: Small intestine neuroendocrine tumors (SI-NETs) get late diagnosis. We discovered the olfactory receptor 51E1 (OR51E1) as a potential target to develop as a novel biomarker.

#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.

#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.

#508 Differential Expression of Markers in a Midgut Carcinoid Tissue Microarray
Introduction: Molecular mechanisms driving well-differentiated midgut carcinoid (MGC) tumors are not well-established. To pursue higher resolution tumor diagnostics, we studied a panel of markers for their expression in MGC, including: serotonin, FGF2, b-catenin, and E-cadherin, in primary, lymph node, and liver metastases.

#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.

#1273 Tissue Prognostic Markers in Pancreatic Neuroendocrine Tumours
Introduction: Pancreatic neuroendocrine tumours (pNETs) are a rare, heterogeneous class of neoplasms, with a rising incidence. Prognosis is variable with 5-year survival as low as 16% in inoperable tumours.
