#1075 Filamin-A Is Required for Somatostatin Receptor 2 (SST2) Stabilization, Signaling and Angiogenesis Regulation in Gastroenteropancreatic Neuroendocrine Tumors
Introduction: Somatostatin receptor type 2 (SST2) is the main pharmacological target for GEP-NETs. A subset of patients is resistant to somatostatin analogs (SSa), although the molecular mechanisms responsible for resistance are poorly understood. Several studies identified cytoskeleton protein as determinant in receptor anchoring and signaling

#2944 Soluble ST2 (sST2) Levels in the Management of Carcinoid Heart Disease in Patients with Neuroendocrine Cancer
Introduction: The identification of a sensitive biomarker to detect the presence and severity of carcinoid heart disease could allow more selective use of clinical and echocardiographic screening. ST2 is a protein belonging to the family of interleukin 1 receptors, present both in the isoform of transmembrane (ST2L) and in the soluble one (sST2). sST2 blocks the anti-inflammatory, anti-hypertrophic, and anti-fibrotic effects of cytokine IL-33 on the myocardium and recent studies have shown that sST2 levels increase in the blood of patients diagnosed with heart failure.

#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.

#1118 Is There an Additional Value of Somatostatin Receptor Subtype 2A Immunohistochemistry Over Somatostatin Receptor Scintigraphy in Predicting Gastroenteropancreatic Neuroendocrine Tumor Response?
Introduction: It is not known whether tumoral somatostatin receptor subtype 2a (sst2a) immunohistochemistry (IHC) has additional value over OctreoScan® uptake in predicting response to PRRT in patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs).

#1097 Epigenetic Manipulation of the Somatostatin Receptor Type 2 in Neuroendocrine Tumor Cells
Introduction: The somatostatin receptor type 2 (sst2) is a target for treatment in patients with neuroendocrine tumors (NET). However, variability in tumoral sst2 expression might lead to variability in response. Epidrugs could increase sst2 levels and improve response to somatostatin analogues (SSA).

#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.

#3000 Patients with Somatostatin Receptor Type 2-Negative Neuroendocrine Tumors Have Sustained Inferior Survival Rates in a Propensity Score-Matched Analysis
Introduction: Sufficient expression of somatostatin receptor type 2 (SST2) in neuroendocrine tumors (NETs) is crucial for treatment with unlabelled somatostatin analogues (SSAs), or peptide receptor radionuclide therapy (PRRT) using radio-labelled SSAs. Impaired prognosis has been described for SST2-negative NET patients, however studies comparing matched SST2-positive and -negative subjects are missing.

#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.

#143 Association of somatostatin receptor 2 immunohistochemical expression with [111In]-DTPA octreotide scintigraphy and [68Ga]-DOTATOC PET/CT in neuroendocrine tumors
Introduction: In the absence of preoperative somatostatin receptor (sst) scans, knowledge of immunohistochemical sst2 tumor expression may help in predicting the success of somatostatin analogue-based follow-up studies and treatment of neuroendocrine tumors (NETs).

#447 SOMscan: Towards a Ga-68-labeled Pan-Somatostatin PET Imaging Probe Based on SOM230 (Pasireotide)
Introduction: The somatostatin receptor subtype sst2 is largely expressed on neuroendocrine tumors. However, current clinical studies indicate that the subtypes sst1, 3, 5 are of substantial relevance as well.
