We have examined the secretogogue responsiveness and the pattern of secretory proteins produced by a transplantable rat pancreatic acinar cell tumor. Dispersed tumor cells were found to discharge secretory proteins in vitro when incubated with hormones that act on four different classes of receptors: carbamylcholine, caerulein, secretin-vasoactive intestinal peptide, and bombesin. With all horm...
Pancreatic morphology and amylase release from isolated pancreatic acimn in response to caerulein was studied in the course of an experimental bile induced acute pancreatitis without acinar necrosis. The inflammation was induced by retrograde microinfusion of 25 RI bile into the rat bile pancreatic duct. A dissociation between functional and structural findings was seen. One hour after the bile...
CD45, a transmembrane protein tyrosine phosphatase required for signal transduction in leukocytes, has recently been found in pancreatic acinar cells. We have investigated the relationship between kinetic expression of CD45 on acinar cells during acute pancreatitis (AP) and the ability of these cells to produce tumour necrosis factor-alpha (TNF-alpha) through mechanisms sensitive to the cellula...
Left portal hypertension and splenic vein occlusion commonly occur with pancreatic tumors, however these signs are rarely observed in patients with acinar cell carcinoma. This report describes a rare left portal hypertension in a patient who presented with a dilated esophagogastric vein upon esophagogastroduodenoscopic examination of a gastric polyp. A contrast-enhanced computed tomography scan...
Rabbit whole meibomian glands were isolated by microsurgical dissection and enzymatic digestion. Both ductal and acinar elements could be separated by subsequent microsurgical manipulation. Epithelial outgrowth could be derived from either the whole gland or the ductal/acinar elements using collagen gel in the serum-containing, growth factor-enriched medium. Two types of outgrowths were observe...
Notch signaling regulates cell fate decisions in a variety of adult and embryonic tissues, and represents a characteristic feature of exocrine pancreatic cancer. In developing mouse pancreas, targeted inactivation of Notch pathway components has defined a role for Notch in regulating early endocrine differentiation, but has been less informative with respect to a possible role for Notch in regu...
