#3852 Novel insights to study the potential of the somatostatin system in NETs and NECs

Introduction: Neuroendocrine tumors (NETs) and carcinomas (NECs) are a heterogeneous group of cancers with increasing incidence worldwide. Surgery is the only curative choice, whereas an effective pharmacological approach for disseminated disease is still lacking. Somatostatin (SS) receptors (SSTs) provide a suitable pharmacological target to treat NETs with SS analogues (SSAs). However, a large proportion of NETs and, particularly most NECs, are unresponsive or resistant to SSAs. The underlying causes remain poorly understood and alternative strategies are needed. Recently, cortistatin (CST), a neuropeptide analogue of SS with comparable affinity to SSTs, emerged as an anti-inflammatory player, with potential antitumoral features.

#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.
