On the basis of recently observed high levels of iNOS expression that correlated with intestinal inflammation in interleukin-2-deficient [IL-2(-/-)] mice, it was postulated that nitric oxide may damage colonic epithelial cells or impair intestinal ep

Somatostatin receptors and their ligands constitute the prototype targeting system for contrast-enhanced detection and radiotherapy of cancer. Radiolabeled synthetic analogs of somatostatin have been successfully used in routine molecular imaging of

Pancreatic islets contain and release high concentrations of GABA. GABA is thought to play a paracrine role in beta-cells. Searching for a paracrine function of GABA in neoplastic beta-cells we performed patch-clamp studies in isolated human insulino

Exocytosis in neuroendocrine cells, such as chromaffin cells, is under the regulatory control of heterotrimeric G proteins. LDCV from bovine adrenal medulla contains alpha o-, beta-, and gamma-subunits of G-protein heterotrimers. Probably G proteins

Similar to neuronal cells, neuroendocrine cells express voltage-dependent ion channels and fire action potentials. Ca2+ influx through voltage-dependent Ca2+ channels couples changes in membrane potential to Ca(2+)-dependent cellular processes, such

Neuroendocrine tumors (NETs) of the foregut type are frequently smaller than 2 cm in diameter and mainly located in the pancreas or the gastric and duodenal wall. Conventional cross-sectional imaging techniques, such as transabdominal ultrasonography

Neuroendocrine tumor (NET) cells of the gastroenteropancreatic system express a variety of voltage-operated Ca(2+) channels (VOCCs). In addition, NET cells release hormones and biogenic amines in distinct patterns, leading to typical hypersecretion s

Neuroendocrine tumors (NETs) are rare neoplasms. Approximately 75% of all cases manifest in the gastroenteropancreatic (GEP) system. Because of the low incidence of NETs, limited data about the clinical outcome and prognostic variables are available.
