Differential Claudin-1 Gene Expression in Neural Crest-Derived Tumors of Common Embryological Origin Abstract #459

Introduction: Pheochromocytoma and paraganglioma are neural crest-derived tumors originating from chromaffin cells, with the former being intra–adrenal in location, while the latter are extra-adrenal.
Aim(s): To investigate the expression of claudin-1(CLDN1), a tight junction protein marker for metastasis and tumor progression, in neural crest-derived tumors.
Materials and methods: Study comprised of 44 pheochromocytoma, 22 paraganglioma and 11 normal adrenal tissue served as control. RNA extracted from each FFPE tissue was reverse transcribed. Real time PCR experiments were performed to study the gene expression on each sample with GAPDH as control.

#16 Endoglin as indicator of metastatic neuroendocrine tumors of the pancreas
Introduction: Neuroendocrine tumors of the pancreas are rare, highly vascularized tumors. Endoglin, a Transforming Growth Factor-β co-receptor, is a marker for angiogenic endothelial cells. Angiogenesis is required for tumor progression and the development of metastases. Recently, endoglin expression was found to be a prognostic marker in pancreatic carcinomas. However, the role of endoglin in neuroendocrine pancreatic tumors has so far not been studied.

#17 Diagnostic efficacy of the secretin stimulation test for the Zollinger-Ellison syndrome: an intra-individual comparison using different dosages in patients and controls
Introduction: The diagnosis of Zollinger-Ellison syndrome is suspected in patients with symptoms of gastric acid hypersecretion, i.e., peptic ulcer disease, malabsorption or diarrhea, or with elevated fasting serum gastrin levels. However, symptoms can be masked by the use of proton pump inhibitors and fasting serum gastrin values are not always conclusive. Therefore, the secretin stimulation test is advocated as the principal diagnostic tool to identify the Zollinger-Ellison syndrome.
