#3505 DRD2 agonist cabergoline abolished the escape mechanism induced by mTOR inhibitor everolimus in pituitary neuroendocrine tumoral cells

Introduction: The mTOR inhibitor everolimus displays antimitotic effects on diverse neoplasms, including pituitary neuroendocrine ones (PitNETs); however, its effect is reduced by an escape mechanism that increases AKT phosphorylation (p-AKT) leading to survival pathway activation. Dopamine receptor type 2 (DRD2) reduces p-AKT in some non-functioning PitNETs (NF-PitNETs) and in lactotrophs MMQ cells, through a β-arrestin2-dependent mechanism.

#2271 Effects of Multi-Receptor Targeting Drugs in Neuroendocrine Tumors Using 3D Cell Culture

Introduction: Symptom control in functioning neuroendocrine tumors(NETs) may be difficult in some cases, thus, new therapeutic options, including multi-receptor targeting drugs are required.

#1581 Evaluation of Somatostatin and Dopamine Receptor Subtype 2 Expression in Pancreatic Neuroendocrine Neoplasms

Introduction: Although somatostatin receptor subtype 2 (SSTR2) and dopamine type 2 receptor (D2R) are reported to be expressed in neuroendocrine neoplasms (NEN), there is a lack of data from studies on a large number of patients with pancreatic NEN.

#819 Immunohistochemical and Genomic Evidence for the Expression of Somatostatin Receptors 1-5 and Dopamine Receptor 2 in Lung Carcinoids

Introduction: Expression of somatostatin receptors (SSTRs) and dopamine receptor 2 (DR2) in neuroendocrine tumors is of clinical importance, as they represent potential targets for diagnosis and treatment.
