#2980 Metabolic Dysregulation and Circadian Clock in Cellular Models of Neuroendocrine Tumors

Introduction: The circadian clock genes encode transcription factors whose interaction with nuclear receptors allows the regulation of cellular metabolism.The invalidation of the genes of the clock core is associated with the development of many endocrine diseases including neuroendocrine cancer. Recently, the family of transcriptional coactivators PGC-1a has been identified as a key element in the integration of cellular metabolic state with the circadian clock. PRC, as a member of the PGC-1 family, was able to interact with several transcription factors, including the CLOCK factor. The specific induction of this PRC factor by the cell cycle, to modulate the energy function, the MAPkinase pathway and the expression of microRNAs, makes it a key factor in the metabolic adaptation of cancer cells.

#2233 Potential Effects of Ketoconazole on ACTH-Producing and Non-ACTH-Producing Neuroendocrine Tumors

Introduction: Prolonged biochemical remission after treatment with steroidogenesis inhibitors has been described in patients with Cushing’s syndrome due to ectopic adrenocorticotropin hormone (ACTH) production. Some studies have suggested antiproliferative and apoptotic effect of ketoconazole in human cancer cells.

#2136 Combination of Capecitabine and Temozolomide for Advanced Thymic Neuroendocrine Tumors

Introduction: In vitro data indicate that the combination of capecitabine(CAP) and temozolomide(TEM) is synergistic for induction of apoptosis in neuroendocrine tumor cell lines. It has been proven that the CAPTEM regimen is associated with an exceptionally high and durable response rate in patients with metastatic pancreatic neuroendocrine tumors. However, there is less evidence to illustrate if the CAPTEM regimen is effective for thymic neuroendorine tumors(TNET).

#1542 Selective Inhibition of PI3Kalpha (BYL719) - Promising Therapeutic Option for Neuroendocrine Tumors?

Introduction: Neuroendocrine tumors are heterogeneous, often functional malignancies and their therapeutic options are limited. As the PI3 kinase signaling is ­in GEP-NENs, selective PI3Kalpha inhibitors may be more potent than panPI3K inhibitors.

#1003 Signalling Pathways in Bronchial Neuroendocrine Tumor Disease and Its Translation to Innovative Targets: The New Kid on the Block

Introduction: Bronchial neuroendocrine neoplasias comprise a wide spectrum of well-differentiated tumors (typical/atypical carcinoids) to undifferentiated carcinomas such as small (SCLC) and large cell (LC) neuroendocrine carcinomas with a fatal prognosis. Therapeutic options are unsatisfactory.
