#2810 Development of a Personalized Human Immunocompetent Ex-Vivo Model of Neuroendocrine Liver Metastasis Using Precision Cut Tissue Slice Technology

Introduction: Liver metastasis (LM) are very frequent (65-95%) and represent a crucial prognostic factor in patients with gastroenteropancreatic neuroendocrine neoplasms (GEP NENs). The paucity of relevant experimental models has limited the understanding of the pathophysiology of NENs and the development of efficient therapeutic strategies

#2707 Investigating the Crosstalk between MEN1, p53 and Notch Reveals Biomarkers of Formation of Primary Pancreatic Neuroendocrine Tumors

Introduction: Pancreatic neuroendocrine tumors (PNETs) comprise a heterogeneous group of endocrine tumors. Previous studies showed that mutations of p53 are extremely rare; whereas genetic changes of MEN1 frequently occur and are correlated with poor prognosis in PNET. Still, their roles in tumorigenesis remain elusive.

#2692 Development of Ex-Vivo Models of Metastatic Neuroendocrine Neoplasms

Introduction: The lack of relevant in-vivo and in-vitro models has precluded investigations of the pathophysiology of metastatic NENs. Organotypic tumour slices retain the complexity of tumours in-vivo without extensive manipulation of the tissue.

#2073 Epigenetic Modulation of Autophagy in Pancreatic Spheroid Cells

Introduction: Pancreatic neuroendocrine malignancy is rising up in the last decade. Despite surgical resection and palliative therapy, an effective therapy has not been developed yet.

#1555 Antitumor Activity of Desmopressin (dDAVP) and the New Analog [V4Q5]dDAVP in Human Small Cell Lung Cancer

Introduction: Lung cancer is the main cause of cancer death. Non small cell lung cancer (NSCLC) cause about 85% of cases and small cell lung cancer (SCLC) represents 15%. Therapy resistance is commonly related with a transformation from adenocarcinoma to SCLC. SCLC shows neuroendocrine (NE) features and exhibits aggressive behavior. In vitro production of vasopressin (AVP) was reported in SCLC. The AVP V1 receptors are associated with mitogenic signaling pathways, while AVP V2 receptor (V2r) is related with an opposite effect. DDAVP is a synthetic analog of AVP that acts as a selective agonist for V2r. DDAVP displays cytostatic and antimetastatic properties in breast and colorectal cancer. In our laboratory a new analog, [V4Q5]dDAVP, showed improved cytostatic activity
