Somatostatin receptor type 2 (SST2) is the main pharmacological target of long-acting somatostatin analogues (SSA) widely used in patients with pancreatic neuroendocrine tumours (P-NETs). A subset of patients is resistant to SSA, although the molecular mechanisms responsible for resistance are poorly understood. Several studies identified cytoskeleton protein interactions as determinant in receptor anchoring, expression and signalling. Since SST2 was recently demonstrated to a...

cAMP is an ubiquitous second messenger that is implicated in the regulation of a wide variety of cell functions, including cell proliferation that is differently affected depending on the cell type. Although the effects exerted by cAMP were initially attributed to PKA activation, two exchange proteins directly activated by cAMP (Epac1/2) have been identified as cAMP targets able to mediate several cAMP effects. Aim of this study was to investigate the effect of cAMP on neuroen...
