Novel Insights in Octreotide Effects on Human Neuroendocrine Cell Line CNDT2.5 Abstract #198

Introduction: Octreotide, the first synthetic somatostatin analog available for clinical use, efficiently binds somatostatin receptors (SSRs) 2 and 5 and may transduce its effects by using SSRs.
Aim(s): To elucidate molecular mechanisms of action of Octreotide in human neuroendocrine cell line CNDT2.5 by gene profiling.
Materials and methods: Gene profiling for CNDT2.5 cells was performed using Affymetrix microarrays. Q-RT-PCR and Western blots validated microarray results. Q-RT-PCR and immunohistochemistry were used to evaluate gene and protein expressions in neuroendocrine midgut primary tumor and metastasis tissues.

#108 Everolimus (RAD001) induces tumor response in patients with medullary thyroid cancer: an in vivo and in vitro study
Introduction: Medullary thyroid cancer (MTC) is a neuroendocrine tumor (NET) of the thyroid C cells which is known to express somatostatin receptors. Octreotide, a somatostatin analogue exerting both antisecretory and antitumor activity in different types of NETs, has shown low efficacy in MTC. Everolimus (RAD001), an inhibitor of mTOR, has shown antitumor effects in patients with NETs and synergistic effects when combined with octreotide. Until recently, RAD001 has never been evaluated in MTC.

#422 The Somatostatin Analogue Octreotide Inhibits Growth of Neuroendocrine Tumor Cells by Triggering Janus Faced Proteins
Introduction: Octreotide is a somatostatin analogue, which improves the management of neuroendocrine tumor (NET) patients. Octreotide acts through somatostatin receptors (SSTRs). However, the molecular mechanisms leading to successful therapy or curative effects are largely unknown, particularly when SSTRs levels are low or absent.

#674 Serum miRNA Expression in Small Intestine Neuroendocrine Tumors and Biological Function of miR-196a in Neuroendocrine Tumor Cells
Introduction: MicroRNAs (miRNAs), post-transcriptional regulators, function either as tumor suppressors or oncogenes. We recently identified five upregulated and four downregulated miRNAs in small intestinal neuroendocrine tumor (SI-NET) tissue. We then started new analysis on body fluids to detect tumor signatures using patients’ serum.
