Effect of ATP-Dependent K+ Channel Openers and Blockers on Serum Concentration of Aldosterone in Rats
There are many reports for involvement of ATP-sensitive potassium channels in pancreatic, cardiac and vascular smooth muscle cells. This study examined the effect of single doses of K+ channel openers diazoxide, minoxidil and K+ channel blockers chlorpropamide, glibenclamide on serum concentration of aldosterone in male rats. Blood samples were obtained 60 minutes after drug treatment and serum...
متن کاملUpregulation of an inward rectifying K+ channel can rescue slow Ca2+ oscillations in K(ATP) channel deficient pancreatic islets
Plasma insulin oscillations are known to have physiological importance in the regulation of blood glucose. In insulin-secreting β-cells of pancreatic islets, K(ATP) channels play a key role in regulating glucose-dependent insulin secretion. In addition, they convey oscillations in cellular metabolism to the membrane by sensing adenine nucleotides, and are thus instrumental in mediating pulsatil...
متن کاملMomordica dioica Stimulated Insulin Secretion from Rat Pancreatic Islets is Independent of ATP-Sensitive K Channel
Antidiabetic and insulin secretagogues activity of Momordica dioica has been reported earlier. In the present work, the effect of Aqueous Extract of Momordica dioica (AEMD) was studied on insulin secretion with an evaluation of its mechanisms of action. Phytochemical analysis of AEMD was also carried out. AEMD showed the presence of alkaloids, saponins, flavonoids, tannins, and sugars. Isolated...
متن کاملK(ATP) channel openers protect rat islets against the toxic effect of streptozotocin.
We examined the influence of two K(ATP) channel openers, diazoxide and an analog (NNC 55-0118), on experimental beta-cell damage induced by streptozotocin (STZ; 0.5 mmol/l). Rat pancreatic islets were exposed to diazoxide or NNC 55-0118 for 30 min and were further incubated for 30 min after the addition of STZ. The islets were then washed and cultured for 24 h. Islets exposed to STZ alone showe...
متن کاملModeling K,ATP--dependent excitability in pancreatic islets.
In pancreatic ?-cells, K,ATP channels respond to changes in glucose to regulate cell excitability and insulin release. Confirming a high sensitivity of electrical activity to K,ATP activity, mutations that cause gain of K,ATP function cause neonatal diabetes. Our aim was to quantitatively assess the contribution of K,ATP current to the regulation of glucose-dependent bursting by reproducing exp...
