#2739 Epigenetic Landscape of Pancreatic Neuro-Endocrine Tumors Reveals Distinct Cells of Origin and Means of Tumor Progression
Introduction: Pancreatic Neuroendocrine Tumors (PanNETs) arise from cells of the Islets of Langerhans. The majority of PanNETs are non-functional and their cell of origin cannot be defined analysing specific hormone production. Cell of origin assessment has proven importance to identify risk factors, prevent tumour development, and tailor treatment in many malignancies. Recent data on super-enhancer signatures has suggested a potential origin of PanNET from α- or β-cells. We and others have shown that distinct epigenetic profiles assessed by DNA methylation (DNAme) characterize genomic and prognostic groups of PanNET.

#3049 Organoid Models of Neuroendocrine Cell Growth and Tumorigenesis
Introduction: A paucity of in vitro and in vivo models has limited the study of Neuroendocrine neoplasms (NENs). Moreover, little is known about normal neuroendocrine (NE) cells and how they contribute to NEN formation.

#2905 DNA Methyltransferase Inhibitor Hydralazine Induces Upregulation of Somatostatin Type 2 Receptors in Human Neuroendocrine Tumor Cells
Introduction: Epidrugs like DNA methyltransferase inhibitors (DNMTi) can increase somatostatin receptor type 2 (SST2) expression in neuroendocrine tumor (NET) cells in vitro and in vivo. This effect could be used for NET patients with low SST2 expression who are currently ineligible for somatostatin analogue (SSA) treatment. However, the DNMTi known to stimulate SST2 have either a high toxicity profile or are not yet approved.

#2988 Epigenetic Treatment with Histone Deacetylase Inhibitor Enhances Uptake of [111In]In-DOTA-TATE by Increased SST2 Expression on Neuroendocrine Tumor Cells
Introduction: The somatostatin-2 receptor (SST2) is a target for peptide receptor radionuclide therapy (PRRT) in neuroendocrine tumors (NETs). By using epigenetic drugs, which can regulate gene transcription, PRRT efficacy may be further improved due to enhanced SST2 expression.

#3320 TGF-β increase caspase activation and migration in typical bronchial carcinoids
Introduction: Typical bronchial carcinoids (TBC) are well-differentiated neuroendocrine neoplasms (NEN) whose management can still be very challenging due to reduced sensitivity to therapy. Previous studies have reported TGF-β’s ability to activate mTOR pathway and induce epithelial to mesenchymal transition (EMT). Moreover, preliminary results show an overexpression of TGF-β signalling and caspase activation in TBC.

#2999 Aberrant Tryptophan Metabolism in Stromal Cells Is Associated with Mesenteric Fibrosis in Small Intestinal Neuroendocrine Tumours
Introduction: Increased levels of serotonin secretion are associated with mesenteric fibrosis (MF) in small intestinal neuroendocrine tumors (SI-NETs). However, only a proportion of patients with increased serotonin production will develop mesenteric fibrosis.

#2800 Thymosin Beta 4 Is an Autocrine Mitogen for Neuroendocrine Tumour Cells
Introduction: The most commonly used NET marker chromogranin A, has a sensitivity between 60-90% and a specificity of less than 50%, hence better NET markers are needed. Previous secretome analysis using BON1, NCI-H727 and SHP-77 cell lines has led to the discovery of various candidate NET markers. One such marker is Thymosin Beta 4 (TB4). TB4 is a small 43 amino acid intracellular peptide first isolated from bovine thymus tissue.TB4 or its oxidised form TB4SO are thought to play a role in various aspects of cancer biology including tumour invasion, metastasis and apoptosis.

#2827 Characterization of Epigenetic Modulation in Pancreatic Neuroendocrine Neoplasms
Introduction: Pancreatic neuroendocrine tumors (PanNETs) represent a rare and heterogeneous tumor entity. Despite advances in therapy cancer progression and resistance mechanisms are still challenging. Recent genome wide sequencing analyses in PanNETs identified a large number of mutated genes involved in epigenetic modulation.

#2908 Re-Cellularised Human Pancreas 3D Scaffolds as a Novel Model for Biomarker Discovery in Pancreatic Neuroendocrine Tumours (pNETs)
Introduction: The lack of preclinical models of pNETs has challenged identification of tissue specific biomarkers of disease. Culturing cancer cells in their native tissue enables the close study of cell-ECM interaction and tissue remodelling. The biological products of such interactions can form a basis for discovery of novel biomarkers of the disease, and were previously linked with a range of inflammatory and malignant conditions.
