Intra-acinar cell activation of trypsinogen during caerulein-induced pancreatitis in rats.
Supramaximal stimulation of the pancreas with the CCK analog caerulein causes acute edematous pancreatitis. In this model, active trypsin can be detected in the pancreas shortly after the start of supramaximal stimulation. Incubation of pancreatic acini in vitro with a supramaximally stimulating caerulein concentration also results in rapid activation of trypsinogen. In the current study, we ha...
متن کاملProtective effect of Tribulus terrestris fruit extract on cerulein-induced acute pancreatitis in mice
Objective: Antioxidant, anti-inflammatory, analgesic and antimicrobial activities of Tribulus terrestris (T. terrestris) could be helpful in the treatment of acute pancreatitis; thus, this study was designed to investigate the effects of T. terrestris on cerulein-induced acute pancreatitis in mice. Materials and Methods: Three doses (100, 200 and 400 mg/kg) of T. terrestris hydro-alcoholic extr...
متن کاملActivating transcription factor 3 promotes loss of the acinar cell phenotype in response to cerulein-induced pancreatitis in mice
Pancreatitis is a debilitating disease of the exocrine pancreas that, under chronic conditions, is a major susceptibility factor for pancreatic ductal adenocarcinoma (PDAC). Although down-regulation of genes that promote the mature acinar cell fate is required to reduce injury associated with pancreatitis, the factors that promote this repression are unknown. Activating transcription factor 3 (...
متن کاملInduction of IkappaB-kinase by cholecystokinin is mediated by trypsinogen activation in rat pancreatic lobules.
BACKGROUND AND AIMS Supramaximal concentrations of cholecystokinin (CCK) or cerulein induce the intracellular activation of trypsinogen and the transcription factor NF-kappaB, a key regulator of inflammatory gene expression. Both events occur early in the development of an acute pancreatitis. The aim of this study was to examine the relationship between intracellular trypsinogen and NF-kappaB a...
متن کاملChronic hypoxia does not cause wall thickening of intra‐acinar pulmonary supernumerary arteries
Chronic exposure to hypoxia causes pulmonary hypertension and pulmonary arterial remodeling. Although the exact mechanisms of this remodeling are unclear, there is evidence that it is dependent on hemodynamic stress, rather than on hypoxia alone. Pulmonary supernumerary arteries experience low hemodynamic stress as a consequence of reduced perfusion due to 90° branching angles, small diameters,...
