MONOPHASIC STATE OF INSULIN SECRETION IN ISOLATED RAT ISLETS OF LANGERHANS BY K+, Ca2+ AND GLUCOSE

Isolation of rat islets of Langerhans was carried out by using collagenase and the destruction of exocrine tissue was performed through the injection of Hanks' solution into the common bile duct. The identification of the islets was done by techniques including the use of a stereomicroscope against a black background. Vital staining was done by an injection of neutral red solution through t...

The role of protein kinase C in the desensitization of rat pancreatic islets to cholinergic stimulation.

It is well known that protein kinase C (PKC) plays an important role in mediating insulin secretion in response to cholinergic stimulation. In various cells PKC also mediates a desensitization process. The role of PKC for homologous desensitization of the insulin response to repetitive stimulation with the muscarinic agonist carbachol (CCh) was investigated in perifusion experiments using isola...

Protein kinase C and calcium regulation of adenylyl cyclase in isolated rat pancreatic islets.

Rat islets express several isoforms of adenylyl cyclase (AC), and the regulation of AC activity in isolated islets by Ca(2+) and protein kinase C (PKC) was investigated. At basal 2.8 mmol/l glucose, the muscarinic receptor agonist carbamylcholine chloride (CCh) evoked a concentration-dependent increase in cAMP generation with a maximum increase at least 4.5-fold above control. In contrast, fors...

Glucose-induced translocation of protein kinase C in rat pancreatic islets.

The role of protein kinase C (PKC) as a mediator of glucose-induced insulin secretion has been a subject of controversy. Glucose-induced translocation of PKC has not been reported, and the relevant PKC isoenzymes in islets have not been identified. To address these issues, we developed specific antibodies to the alpha, beta, and gamma isoenzymes of PKC. Western blots of homogenates of freshly i...

The role of Langerhans islets in pancreatic ductal adenocarcinoma.

An intimate relationship between the exocrine and endocrine pancreas has been convincingly demonstrated in recent years. Animal experiments have shed some light into the complex dialog between the two tissues. This interaction is pronounced in diseases of the pancreas, especially in experimentally-induced and human pancreatic cancers. New evidence highlights the importance of intact islets in t...
