#2141 Potential Role of SST5TMD4-Derived Peptides in the Malignancy of Neuroendocrine Tumors and Other Endocrine-Related Cancer Cells

Introduction: Extracellular fragments derived from membrane receptors can play relevant functional roles in certain tumoral pathologies and could provide novel diagnostic or therapeutic tools. We have identified a novel truncated somatostatin receptor type 5 variant, sst5TMD4, which is overexpressed and functionally active in different endocrine-related cancers, including neuroendocrine tumors (NETs). Interestingly, sst5TMD4 has 4 transmembrane domains and its C-terminal tail is consequently exposed towards the extracellular matrix, and could, therefore, be the substrate for proteolytic enzymes.

#1875 Potential Anti-Tumor Activity of Biguanides and Statins in Neuroendocrine Tumor Cells

Introduction: Recent studies have suggested that biguanides and statins have beneficial effects on various cancer types; however, the precise effects and the molecular mechanisms underlying this pathophysiological association are still not well understood in neuroendocrine tumor (NETs).

#1566 Splicing Dysregulation Impacts on Neuroendocrine Tumors: Evidence from Altered Spliceosoma Components and Somatostatin and Ghrelin Systems.

Introduction: Splicing is an emerging cancer hallmark influencing multiple tumor cell (dys)functions. We have shown that aberrantly spliced variants of somatostatin receptor subtype 5 (sst5TMD4) and of the pleiotropic neuropeptide ghrelin (in1ghrelin) are linked to poor prognosis in gastroenteropancreatic neuroendocrine tumors (GEPNETs) and may enhance their aggressiveness features.
