#1936 The Expression of IGF Signaling Pathway Genes Is Frequently Elevated in Pancreatic Neuroendocrine Tumors, but Is Downregulated in Metastases

Introduction: Studies have implicated EGFR, IGF and mTOR signaling pathways in the regulation of pNET growth. Interpretation of these studies is complex due to tumor subtype heterogeneity and differences in molecular analysis.

#780 Epigenetic Regulation of Endogenous Somatostatin Expression in Neuroendocrine Tumors

Introduction: Somatostatin (SST) can regulate hormone secretion and cell proliferation in neuroendocrine tumors (NETs). SST expression levels in NETs likely differ between patients. DNA methylation inhibits gene transcription and can be reversed by the demethylating drug 5-aza-2-deoxycytidine (AZA).

#269 Expression of IGF/mTOR Pathway Components in Human Pheochromocytomas and In Vitro Inhibition of PC12 Rat Pheochromocytoma Cell Growth by mTOR Inhibitors

Introduction: The pathogenesis of pheochromocytomas (pheo) is poorly understood and malignant pheo need new treatment options. mTOR inhibitors, as sirolimus(S) and everolimus(E), are promising antineoplastic drugs.
