mTOR Inhibitors Hamper Cell Viability in Selected Human Medullary Thyroid Carcinoma Primary Cultures Abstract #430

Introduction: It has been demonstrated that mTOR inhibitors have potent anti-proliferative effects in a human Medullary Thyroid Carcinoma (MTC) cell line. We here explore the possible role of mTOR inhibitors, Everolimus and BEZ235 (which also inhibits the PI3K pathway) on the effects of Insulin-like Growth Factor-1 (IGF-1) in human MTC primary cultures.
Aim(s): To this purpose, 20 MTCs were dispersed in primary cultures, treated without or with 1uM Everolimus, 10nM-1uM BEZ235, and/or 50nM IGF-I
Materials and methods: Cell viability and apoptosis were evaluated after 48 h. We observed the phosphorylation of p70s6k by ELISA.

#429 Bronchial Carcinoid Response to mTOR Inhibitors Depends on mTOR Expression Levels
Introduction: Bronchial carcinoids (BCs), originating from endocrine cells dispersed in the respiratory epithelium, can be divided into typical (TBC) and atypical (ABC). TBC are less aggressive, smaller, and much less likely to metastasize, while ABC are more aggressive and metastasize. mTOR has a central role in regulating cell growth, metabolism, and apoptosis. A differential mTOR activation in BCs has been previously demonstrated, suggesting that mTOR pathway might play a predictive role in patients eligible for mTOR-targeted therapies

#1086 mTOR Down-Stream Signaling Pattern May Predict pNET Response to Everolimus
Introduction: NETs are rare neoplasms arising from neuroendocrine cells spread in the respiratory and gastro-entero-pancreatic epithelium. The mammalian target of rapamycin (mTOR) pathway plays a central role in the regulation of cell growth, metabolism, and apoptosis representing a novel molecular target. This pathway is constitutively activated in pancreatic NETs (pNETs) providing the basis for the development of specific mTOR inhibitors as new therapeutic tools.

#226 Insulin-like Growth Factor-1 Receptor (IGF-1R) and its Inhibition in Non-functioning Neuroendocrine Tumors
Introduction: Insulin-like growth factor-1 receptor (IGF-1R) was reported to be expressed in NET (neuroendocrine tumor) cells but its biological roles and activation status in non-functioning NET are unknown.

#962 Cyclin D1 Levels are Involved in the Resistance to m-TOR Inhibitors in Human Bronchial Carcinoids
Introduction: Bronchial carcinoids (BC) are still orphans of medical therapy. We previously demonstrated that the typical BC human cell line NCI-H727 is sensitive to Everolimus, in terms of cell viability reduction, while the atypical human BC cell line NCI-H720 is not. However, the mechanisms underlying this phenomenon have not been fully clarified.

#1494 CDK-Inhibitors as New Therapeutic Treatment for Human Bronchial Carcinoids
Introduction: Bronchial Carcinoids (BC) are still orphan of medical therapy. We previously demonstrated that 70% of primary BC cultures are sensitive to Everolimus (E), an mTOR inhibitor, while 30% are not. We also observed that in 2 human BC cell lines, the NCI-H720 (sensitive to E) and NCI-H727 (resistant to E), mTOR resistance may be linked to a differential cell cycle protein expression (CyclinD1/E, CDK2/4, p27kip1/p27kip1phospho-Ser10), which is higher in BC resistant to E as compared to sensitive ones, suggesting an impaired p27 function
