#4656 Development of a 3D patient-derived extracellular matrix hydrogel model of small intestinal neuroendocrine tumour and mesenteric fibrosis

Introduction: The pathogenesis of mesenteric fibrosis in small intestinal neuroendocrine tumours (SI-NETs) is poorly understood, limiting development of effective treatments and biomarkers. A major barrier to research is the lack of disease models.

#4157 Decoding and targeting of metabolic heterogeneity in pancreatic neuroendocrine tumors (PanNETs): MCT1 and MCT4 in the crosshair for precision therapy

Introduction: Mechanisms driving progression from indolent to aggressive and metastatic disease in PanNET are largely unknown. Recent transcriptome and epigenome analyses suggest a stepwise progression model leading to enhanced proliferation, de-differentiation, and metabolic reprogramming. However, the metabolic landscape at different stages and the therapeutic potential of targeting metabolic proteins remain largely uncharacterized.

#4041 Mesenteric fibrosis in small intestinal neuroendocrine tumors (SI-NETs): Pathogenesis and therapeutic targets

Introduction: Mesenteric fibrosis (MF) affects up to 50% of small intestine neuroendocrine tumor (SI-NET) patients, causing significant morbidity and mortality. MF pathophysiology is poorly understood, limiting treatment development and biomarker identification.

#3793 Decellularised pancreas explants as a novel 3D model for pancreatic neuroendocrine tumors (PNETs) biomarker discovery

Introduction: The lack of preclinical models of pancreatic neuroendocrine tumors (pNETs) challenges advancement in biomarker discovery. Culturing cancer cells in their native tissue enables the study of complex tumor cell-ECM interactions, products of which could be utilised as disease biomarkers.

#3358 Evaluation of Helicobacter pylori proteins in the pathogenesis of type 1 gastric neuroendocrine tumor and urticaria. In-silico approach

Introduction: Helicobacter pylori (Hp) has been linked to several diseases such as chronic spontaneous urticaria (CSU), gastritis, and type 1 gastric neuroendocrine tumors (T1-GNET). Although these diseases seem to have different mechanisms, their relationship with Hp suggests a possible common inflammatory pathway.
