#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.

#680 Role of EGF Pathway in Regulating Bronchial Carcinoid Cell Proliferation

Introduction: Bronchial carcinoids (BC) are rare neuroendocrine tumors. Surgery is not feasible for infiltrating and metastatic disease. Medical therapy is often tried but is represented by chemotherapy and radiation, while somatostatin analogues are employed for symptomatic control. It is necessary to identify new molecules capable of providing medical treatment in cases for which surgical removal is not feasible. EGF, TGFα are growth factors which were demonstrated to be important in neuroendocrine tumors. EGF and TGFα bind to the EGF receptor and lead to the transcription of genes that regulate cell proliferation.

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

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.

#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

#266 Everolimus Reduces Cell Viability in Selected Human Medullary Thyroid Carcinoma Primary Cultures

Introduction: It has been demonstrated that everolimus, an mTOR inhibitor, has a potent anti-proliferative effect in a human Medullary Thyroid Carcinoma (MTC) cell line, TT, and in two human MTC primary cultures.
