Cerulein pancreatitis: oxidative stress, inflammation, and apoptosis.
Cerulein pancreatitis is similar to human edematous pancreatitis, manifesting with dysregulation of digestive enzyme production and cytoplasmic vacuolization, the death of acinar cells, edema formation, and infiltration of inflammatory cells into the pancreas. Reactive oxygen species are involved in nuclear factor-kappaB activation, cytokine expression, apoptosis and pathogenesis of pancreatiti...
متن کاملThe endogenous scavengers in cerulein-induced acute pancreatitis.
Studies in animal models suggest that oxygen radicals are important in the pathogenesis of acute pancreatitis. Cerulein, a decapeptide isolated from the skin of the frog, Hyla caerula, is closely related to the C-terminus of cholecystokinin and it is a potent stimulant of pancreatic exocrine secretion. The aim of the present study was to measure the activity of endogenous scavengers, superoxide...
متن کاملBone Morphogenetic Protein Signaling Protects against Cerulein-Induced Pancreatic Fibrosis
Bone morphogenetic proteins (BMPs) have an anti-fibrogenic function in the kidney, lung, and liver. However, their role in chronic pancreatitis (CP) is unknown. The aim of this study was to define the anti-fibrogenic role of BMP signaling in the pancreas in vivo under CP induction. Mice with a deletion of BMP type II receptor (BMPR2(+/-)) were used in this study in comparison with wild-type mic...
متن کاملDocosahexaenoic Acid Inhibits Cerulein-Induced Acute Pancreatitis in Rats
Oxidative stress is an important regulator in the pathogenesis of acute pancreatitis (AP). Reactive oxygen species induce activation of inflammatory cascades, inflammatory cell recruitment, and tissue damage. NF-κB regulates inflammatory cytokine gene expression, which induces an acute, edematous form of pancreatitis. Protein kinase C δ (PKCδ) activates NF-κB as shown in a mouse model of cerule...
متن کاملPretreatment with obestatin inhibits the development of cerulein-induced pancreatitis.
Obestatin is a peptide derived from the proghrelin, a common prohormone for ghrelin and obestatin. Obestatin, like the ghrelin has been originally extracted from rat stomach, and the stomach seems to be a major source of circulating obestatin. Previous studies have shown that administration of ghrelin exhibits protective effect in the pancreas, inhibiting the development of acute pancreatitis. ...
