Sulfonylurea drugs stimulate endogenous insulin secretion by blockade of ATP-sensitive potassium channels in pancreatic beta cells. These drugs are widely used in the treatment of type 2 diabetes. However, as ATP-sensitive potassium channels also exist in cardiomyocytes and coronary and peripheral arterial vascular smooth muscle cells, sulfonylurea drug usage in theory may cause unwanted cardio...
Neurons express a variety of plasma-membrane potassium channels that play important roles in regulating neuronal excitability and synaptic transmission, but also contain mitochondrial ATP-sensitive potassium channels, the functions of which are unknown. Studies of cardiac cells suggest that similar mitochondrial ATP-sensitive potassium channels are involved in the process of ischemic preconditi...
A model has been used to simulate potassium (K) uptake by wheat in a pot culture experiment. Three soils from India, namely Alfisol, Inceptisol and Vertisol, were differentially K exhausted by Sudan grass (Surghum vulgare var. Sudanensis) for a period of 280 days and were used to simulate potassium uptake by wheat (Triticum aestivum) and also to predict the amounts of K released or fixed during...
Racial differences in erythrocyte potassium effluxes mediated by two loop-diuretic sensitive modes of cotransport were compared. In red cells loaded to contain approximately equimolar amounts of sodium and potassium, black subjects had lower bumetanide-sensitive sodium-dependent net potassium effluxes as compared to whites. In fresh, washed erythrocytes pretreated with N-ethylmaleimide (NEM), m...
Pinacidil belongs to a novel group of compounds that enhance the potassium permeability of vascular smooth muscle. Evidence also exists that this drug enhances the potassium permeability of cardiac tissue. The purpose of the present investigation was to determine if pinacidil alters potassium-channel activity in heart and, if so, which potassium channel is the target. We used the whole-cell arr...
