#4150 Uncovering the role of netrins and DCC (deleted in colorectal cancer) in pancreatic neuroendocrine neoplasms (PNEN) tumorigenesis

Introduction: DCC functions as a tumor suppressor and is altered in various tumors, including neuroendocrine neoplasms. Netrin (NTN)-1 serves as the primary ligand for DCC. Operating as a dependence receptor, DCC induces apoptosis without NTN and promotes cell survival in its presence. In some cancers like small cell lung cancer and neuroblastoma, upregulation of NTN-3 rather than NTN-1 has been observed. However, the precise involvement of NTNs and DCC in PNEN remains unclear.

#1847 CXCR4 Inhibition by Ulocuplumab Prevents EMT of pNET Cells in Vitro

Introduction: Neuroendocrine tumors (NETs) overexpress CXCR4. We have previously shown that stimulation of CXCR4 by its ligand SDF-1 promotes the epithelial-mesenchymal transition (EMT) and increases distant tumor spread. Ulocuplumab (Ulo) is a fully human IgG4 mAb designed to inhibit the binding of CXCR4 to SDF-1.

#730 Loss of Chromosome 18 in Neuroendocrine Tumors of the Midgut

Introduction: The genetic alterations in neuroendocrine tumors (NET) of the midgut, in particular of the appendix (aNET), are poorly characterized. The most frequent chromosomal aberration in ileal NET (iNET) is the loss of one chromosome 18. The relevance of this alteration is unclear.

#604 Expression of Netrin-1 and its Receptors in pNETs

Introduction: Netrin-1, a member of axon guidance molecules, and its dependence receptors (DCC, UNC5, neogenin) is involved in several cancer types (breast, neuroblastoma, colon etc) but its role in pNETs remains unknown.

#562 Expression of Chromosome 18 Related Tumor Suppressor Proteins in Ileal Neuroendocrine Tumors

Introduction: The genetic alterations in ileal neuroendocrine tumors (iNETs) are poorly characterized. The most frequent chromosomal aberration is the loss of one chromosome 18 in iNETs, however, the relevance of this alteration is unclear.
