Re-Cellularised Human Pancreas 3D Scaffolds as a Novel Model for Biomarker Discovery in Pancreatic Neuroendocrine Tumours (pNETs) Abstract #2908

Introduction: The lack of preclinical models of pNETs has challenged identification of tissue specific biomarkers of disease. Culturing cancer cells in their native tissue enables the close study of cell-ECM interaction and tissue remodelling. The biological products of such interactions can form a basis for discovery of novel biomarkers of the disease, and were previously linked with a range of inflammatory and malignant conditions.
Aim(s): To validate a decellularised human pancreas derived ECM scaffold as a novel and more clinically relevant platform for biomarker discovery and drug screening using cultured pNET cells.
Materials and methods: BON-1 and QGP-1 cell lines were cultured in decellularised pancreas derived ECM scaffolds. Viability, proliferation, and morphological characteristics were studied using viability assays and histology. Functional characterisation was performed using immunohistochemistry and genetic expression analysis with real-time PCR, and compared with 2D monolayer cultures.

Introduction: Pancreatic neuroendocrine tumors (PNET) remain an unmet clinical need. In this study, we show that targeting both nicotinamide phosphoribosyltransferase (NAMPT) and p21-activated kinase 4 (PAK4) could become a synthetic lethal strategy for PNET.

#2685 Apatinib Inhibits Tumor Growth and Angiogenesis in PNET Models
Introduction: Angiogenesis has a pivotal role in the growth and metastasis of pancreatic neuroendocrine tumors (PNETs). Apatinib inhibits angiogenesis as a highly selective KDR inhibitor and has been used to treat advanced gastric cancer and malignancies in clinical settings. However, the efficacy of apatinib in PNETs remains unclear.

#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.
