#1906 High Prevalence of the c.1546delC Germline Mutation in MEN1 Pancreatic Neuroendocrine Tumors
Introduction: Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant disease predisposing to pancreatic neuroendocrine neoplasms (NENs). Even though its genetics is relatively well known, specific phenotype-genotype correlations remain unproven at present. The Region of Murcia in southeast Spain is one of the areas with the highest incidence of MEN1

Keywords: MEN1 genetics
#262 Changes on Chromosome 18 are Involved in Sporadic and Familial Ileal Carcinoid Tumor Development
Introduction: Small intestine neuroendocrine tumors (ileal carcinoid) is generally considered a sporadic disease. We have identified nine families with an ileal carcinoid tumor diagnosed in two or more individuals.

#780 Epigenetic Regulation of Endogenous Somatostatin Expression in Neuroendocrine Tumors
Introduction: Somatostatin (SST) can regulate hormone secretion and cell proliferation in neuroendocrine tumors (NETs). SST expression levels in NETs likely differ between patients. DNA methylation inhibits gene transcription and can be reversed by the demethylating drug 5-aza-2-deoxycytidine (AZA).

#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.

#861 Targeted Next Generation Sequencing in the Screening for Familial Neuroendocrine Tumor Syndromes: A Tool for Personalized Medicine
Introduction: Multiple syndromes are described as conferring susceptibility to NETs; MEN1 & 2, NF1, familial PGL 1-5, TSC, VHL and germline mutations in the HIF2A, MAX, or TMEM127. Genetic testing covering these diagnoses may be extensively resource-demanding using traditional techniques due to the large extent of these loci.

#936 Promoter Hypermethylation at RASSF1 is a Feature of Small Intestinal Neuroendocrine Tumors
Introduction: Promoter hypermethylation of RASSF1 has been reported in many tumor types.

#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.

#976 Upregulation of Somatostatin Receptor Type 2 Expression in Neuroendocrine Tumors by Epigenetic Modulation
Introduction: The somatostatin receptor type 2 (sst2) is a target for treatment of neuroendocrine tumors (NETs). However, epigenetic mechanisms might account for the high variability in sst2 expression and treatment response between patients.

#1227 Molecular Profiling of Small Intestinal Neuroendocrine Tumours (SINETs)
Introduction: Aberrant DNA methylation plays an role in the pathogenesis of many cancers, however little is known about its role in SINET development.

#1465 Assocation Between miRNAs and HDACs in Pancreatic Neuroendocrine Tumors
Introduction: Epigenetic factors are essentially involved in carcinogenesis, tumor promotion and chemo resistance with their major key players of miRNAs and histone deacetylases (HDACs). As shown by own theoretical databank analysis, the crosstalk between miRNAs and HDACs are relevant in different human chronic diseases and cancerogenic pathways.
