Myocardial ischemia and infarction are associated with substantially increased morbidity and mortality among patients with diabetes mellitus. Although many factors contribute to the increased morbidity and mortality, in patients with non-insulin-dependent (type II) diabetes mellitus, one contributor may be the use of sulfonylurea drugs, the most widely used oral hypoglycemic agents. Such a poss...
The pancreatic ATP-sensitive potassium (K(ATP)) channel consisting of four inwardly rectifying potassium channel 6.2 (Kir6.2) and four sulfonylurea receptor SUR1 subunits plays a key role in insulin secretion by linking glucose metabolism to membrane excitability. Syntaxin 1A (Syn-1A) is a plasma membrane protein important for membrane fusion during exocytosis of insulin granules. Here, we show...
Murraya koenigii L. is a perennial shrub, belonging to the family Rutaceae. Traditionally, the leaves of this plant are extensively used in treatment of a wide range of diseases and disorders including pain and inflammation. Although researchers have revealed the antinociceptive effects of this plant's leaves during past few years, the mechanisms underlying these effects are still unknown. Ther...
Expression and function of ATP-dependent potassium channels in zebrafish islet β-cells." Royal function of ATP-dependent potassium channels in zebrafish islet β-cells. ATP-sensitive potassium channels (K ATP channels) are critical nutrient sensors in many mammalian tissues. In the pancreas, K ATP channels are essential for coupling glucose metabolism to insulin secretion. While orthologous gene...
Understanding mechanisms by which glibenclamide stimulates insulin release is important, particularly given recent promising treatment by glibenclamide of permanent neonatal diabetic subjects. Antidiabetic sulfonylureas are thought to stimulate insulin secretion solely by inhibiting their high-affinity ATP-sensitive potassium (K(ATP)) channel receptors at the plasma membrane of beta-cells. This...
BACKGROUND Cardiac myocytes demonstrate significant swelling and associated reduced contractility in response to stress that is prevented by the ATP-sensitive potassium channel opener, diazoxide (DZX) via an unknown mechanism. One proposed mechanism of cardioprotection is mitochondrial matrix swelling. To establish the relationship between mitochondrial and cellular volume during stress, this s...
Infection may result in early abnormalities in respiratory movement, and the mechanism may involve central and peripheral factors. Peripheral mechanisms include lung injury and alterations in electrolytes and body temperature, but the central mechanisms remain unclear. In the present study, brainstem slices harvested from rats were stimulated with lipopolysaccharide at different doses. Central ...
