#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.

#2898 Novel Preclinical Models of Small Bowel Neuroendocrine Tumors for Drug Screening
Introduction: The incidence of neuroendocrine tumors (NETs) from the small bowel (SBNETs) has increased markedly over the past several decades. Many patients with these tumors present with metastatic disease, and research into new treatment options for these tumors have been hindered by the limited number of patient-derived SBNET cell lines and in vivo models available for drug testing.

#220 The Global mTOR Inhibitor Torin1 is More Effective than the mTORC1 Inhibitor, Everolimus, Alone or in Combination with Histone Deacetylases Inhibitors, in Suppressing Neuroendocrine Tumors Cell Proliferation
Introduction: Torin1, a new mTOR inhibitor that globally inhibits both mTORC1 and mTORC2, seems to impair cell growth and proliferation to a greater degree than rapamycin; its effects in NET cells are unknown.

#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.

#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.

#2745 Integrative Genomic Characterization Identifies Molecular Subtypes of Lung Carcinoids
Introduction: Lung carcinoids (LCs) are rare and slow growing primary lung neuroendocrine tumors. The WHO classify LCs into atypical and typical carcinoids. Recent studies have shown that the reproducibility of LCs classification and its prognostic efficacy have high interobserver variability

#2902 DNA Methylation Analysis of the PDX1 Gene Can Be Used for PNET Subtyping and Has a Possible Prognostic Value
Introduction: Estimating prognosis of pancreatic neuroendocrine tumor (PNET) patients remains challenging. Mutation status of DAXX/ATRX/MEN1, histone modification patterns and immunohistochemistry for relevant transcription factors, including PDX1, were recently used to perform subtyping and distinguished two main types, A and B. These subtypes are linked to cell-of-origin and associated with clinical outcome.

#2975 Next Generation Sequencing of Pancreatic Neuroendocrine Tumors in Russian Cohort
Introduction: The appearance of next generation sequencing (NGS), - a powerful high-performance method, allowed accumulation of a large amount of information concerning genetic and epigenetic patterns, however, the problem of matching clinical, histological picture with genetic structure in pNETs remains open.

#119 Valproic acid induces apoptosis-mediated cell death of the ileal carcinoid cell line GOT1
Introduction: Downregulation of tumor suppressor genes, evasion from apoptosis, and reduced differentiation are hallmarks of cancer that can be due to abnormal epigenetic control. Histone deacetylase (HDAC) is an enzyme involved in the deacetylation of histone proteins, resulting in chromatin remodelling and altered gene transcription. HDAC inhibitors are emerging as useful anticancer drugs.

#616 Assessment of DNA Double-Strand Breaks in Blood Lymphocytes after Whole-Body Radiation Exposure in Patients with Neuroendocrine Tumors Undergoing 177Lu-Octreotate Therapy
Introduction: Peptide receptor radionuclide therapy using somatostatin receptor-binding peptides, such as 177Lu-Octreotate (LuTate), has been clinically proven to be effective in treating patients with inoperable neuroendocrine tumors. Despite the rather high radiation exposure, only few side effects have been reported. However, blood cells are very sensitive to radiation. Therefore, it is important to determine how much radiation they received. Recently, the detection by immunofluorescence of the phosphorylation of the histone variant H2AX (γ‐H2AX) has been established as a reliable and sensitive technique to monitor DNA double-strand breaks (DSBs) in blood lymphocytes.
