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

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.
Aim(s): To investigate the cAMP effects in neuroendocrine tumorous cells on cell proliferation and adhesion to determine the role of Epac and PKA in mediating these effects.
Materials and methods: We tested the effects of different cAMP analogs (Epac-selective, PKA-selective, or non selective) on cell proliferation, evaluating also the cyclin D1 and p27 expression, and on cell adhesion, in neuroendocrine primary culture (gastroenteropancreatic-NET and bronchial carcinoid) and in appropriate cell lines (QGP1 and H727).

#1075 Filamin-A Is Required for Somatostatin Receptor 2 (SST2) Stabilization, Signaling and Angiogenesis Regulation in Gastroenteropancreatic Neuroendocrine Tumors
Introduction: Somatostatin receptor type 2 (SST2) is the main pharmacological target for GEP-NETs. A subset of patients is resistant to somatostatin analogs (SSa), although the molecular mechanisms responsible for resistance are poorly understood. Several studies identified cytoskeleton protein as determinant in receptor anchoring and signaling

#2001 The Anticancer Mechanism of Metformin in Pancreatic Neuroendocrine Tumor Cells
Introduction: Metformin, a widely used antidiabetic drug, has been reported to display potent anticancer properties in various types of cancers. In P-NETs, aryl hydrocarbon receptor-interacting protein (AIP) acts as a tumor suppressor and is up-regulated by the somatostatin analog octreotide.

Introduction: Carcinoid serotonin (5-HT) causes local fibrosis but the effect of 5-HT on hepatocytes has not been established. We hypothesized that tumors and hepatocytes form a metastasis-supportive environment.
