#1642 Angiogenic Circulating Biomarkers in Patients with Advanced Pancreatic Neuroendocrine Tumors Treated with Everolimus

Introduction: More than 10% of patient treated with Everolimus develop early onset of resistance. The lacking of adequate predictive factors in the targeted hera makes challenging the early identification of non-responders patients.

#1637 The Effect of the Autophagy Inhibitor Chloroquine (CQ), Alone or in Combination with mTOR Inhibitors, on Neuroendocrine Tumor (NET) Growth and Metastatic Spread in Mouse Models

Introduction: mTOR inhibitors (mTORi) such as RAD001 demonstrated promising anti-cancer effect in NETs. Autophagy, a cell survival mechanism, is activated by mTORi. We have recently shown in the human NET cell line BON1 that autophagy is essential for cell survival. Treatment with CQ alone or together with mTORi robustly inhibited cell proliferation and survival, suggesting that treatment with CQ may potentiate the anti-tumorigenic effects of mTORi.

#1172 Dual Inhibition of PI3K and mTORC1/C2 by PKI-587 (PF-05212384) as a Promising Therapeutic Option for Gastroenteropancreatic Neuroendocrine Tumor Disease and Its Effect on AKT-Signaling

Introduction: Gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN) are heterogeneous in their clinical behavior and therapeutic options are still not satisfactory. The “crosstalk” of different signaling pathways in NEN cells appears to be more complex as known already. PKI-587 is a highly potent novel dual inhibitor of PI3K and mTORC1/C2.

#1109 Expression and Role of the CXCR4/CXCL12/CXCR7 Axis and Crosstalk with the mTOR Pathway in Neuroendocrine Tumors (NETs)

Introduction: Chemokine receptor CXCR4 has been shown to signal on mTOR pathway in gastric and renal cancer. CXCR4 interacts with the chemokine CXCL12 to exert proliferative and chemotactic effects.

#1090 p27kip1 Is Involved in the Resistance of Human Bronchial Carcinoids to m-TOR Inhibitors

Introduction: Bronchial carcinoids (BC) are still orphan of medical therapy. We previously demonstrated that the typical BC human cell line NCI-H727 is sensitive to Everolimus (E), in terms of cell viability reduction, with a G0 cell-cycle arrest, while the atypical human BC cell line NCI-H720 is not. The mechanisms underlying this phenomenon have not been clarified
