#200 Genome-Wide MicroRNA Expression in Small Intestine Neuroendocrine Tumors (“Midgut carcinoids”): Upregulation of miRNA-182, miRNA-183 and Downregulation of miRNA-215
Introduction: MicroRNAs (miRs) may regulate cell proliferation, differentiation, apoptosis and function as tumor suppressors or oncogenes. MiR expression is not characterized in neuroendocrine midgut carcinoids.

#355 MicroRNA Signatures as Novel Biomarkers in Small Intestine Neuroendocrine Tumors
Introduction: Small intestine (SI) neuroendocrine tumors (NET) arise from serotonin-producing intraepithelial cells in the SI referred to as enterochromafin cells. The detection of SI-NETs is often concomitant with the appearance of hepatic metastasis thus most patients with SI-NET have metastases at initial presentation. MicroRNAs (miRs) are post-transcriptional key regulators in tumorigenesis which regulate expression of other genes. Little evidence of miR expression or deregulation in SI-NETs has been reported.

#830 The Predictive Value of Gastrin Levels for the Diagnosis of Gastric Enterochromaffin-like Cells Hyperplasia, in Patients with Hashimoto’s Thyroiditis
Introduction: Gastrin and chromogranin A (CgA) levels have been tested for the diagnosis of enterochromaffin-like cell hyperplasia (ECLH), in patients with type 1 diabetes and autoimmune atrophic gastritis but there are no data for patients with Hashimoto's thyroiditis (HT).

#585 Global microRNA profiling of small intestine neuroendocrine tumors (SI-NETs) and establishment of a method to study serum microRNA expression from the same tumors

#422 The Somatostatin Analogue Octreotide Inhibits Growth of Neuroendocrine Tumor Cells by Triggering Janus Faced Proteins
Introduction: Octreotide is a somatostatin analogue, which improves the management of neuroendocrine tumor (NET) patients. Octreotide acts through somatostatin receptors (SSTRs). However, the molecular mechanisms leading to successful therapy or curative effects are largely unknown, particularly when SSTRs levels are low or absent.

#905 Cancer-Associated-Fibroblasts in Neuroendocrine Neoplasms: A Role in Cancer Progression
Introduction: Cancer-associated-fibroblasts (CAFs) secrete soluble factors that enhance tumor growth and invasion. Neuroendocrine tumor (NET) cells recruit fibroblasts within the lesional sites.

#424 Role of MicroRNAs in Small Intestine Neuroendocrine Tumors
Introduction: Small intestinal neuroendocrine tumors (SI-NETs) arise from enterochromaffin cells, which belong to the endocrine system. MicroRNAs (miRs) are post-transcriptional regulators. They control multiple biological processes often functioning either as tumor suppressor genes or oncogenes.

#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.

#801 Normal Gastrointestinal Neuroendocrine Cells Lack E-cadherin
Introduction: E-cadherin plays a crucial role in the adhesion between epithelial cells and thus epithelial integrity. Moreover, germ line mutations in the E-cadherin gene (CDH1) causing loss of E-cadherin function (adhesion) leads to hereditary gastric cancer of the diffuse type, according to Laurén. Even sporadic gastric carcinomas of the diffuse type often lose E-cadherin expression due to mutations. Lack of E-cadherin has been recorded at an early phase in such carcinomas.
