#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.

#894 The Effects of cAMP in Different Neuroendocrine Tumorous Cells: The Role of Epac and PKA in Cell Proliferation and Cell Adhesion

Introduction: cAMP is implicated in the inhibition or stimulation of proliferation depending on cell type. Although the effects exerted by cAMP were initially attributed to the PKA activation, two cAMP-activated guanine nucleotide exchange (Epac1/2) have been later identified as cAMP targets.

#87 Alterations of E-cadherin, beta-catenin and caveolin-1 expression in gastroenteropancreatic neuroendocrine tumors

Introduction: Gastroenteropancreatic neuroendocrine tumors (GEP NETs) comprise a heterogeneous group of neoplasm with different histological patterns and biological behavior. Only limited information is available on immunohistochemical prognostic factors of disease. Alterations in the cell-cell adhesion system are closely associated with cell invasion and metastasis in many malignancies, including those of endocrine origin. Abnormal expression of E-cadherin and beta-catenin has been reported to play an important role in these processes. Caveolin-1 has recently been identified as a tumor metastasis modifier factor, which might increase the cell metastasis potential through the interaction with E-cadherin. However, the role of caveolin-1 in GEP NETs cell invasion remains unknown.
