#2984 AGTR1 Is Overexpressed in Neuroendocrine Neoplasms, Regulates Secretion and May Serve as a Target for Molecular Imaging and Therapy

Introduction: Peptide receptor targeting has proven to be a pivotal tool for diagnostic imaging and radioligand therapy of neuroendocrine neoplasms (NENs), which frequently express somatostatin receptors (SSTRs) on their cell surface. However, up to 30 % of NEN patients do not benefit from SSTR-based approaches, others develop a resistance.

#2294 Identification and Validation of the Angiotensin II Receptor Type 1 as a Possible Anti-Cancer Target in Neuroendocrine Tumors

Introduction: Neuroendocrine tumours (NETs) have been found to overexpress somatostatin receptors (SSTRs), which led to the development of somatostatin analogs utilized for diagnostics and therapeutics. However, around 30% of all NETs do not respond to somatostatin based approaches, leading to an interest to find and characterize alternative cell surface targets.
