Stimulation of Na+ -dependent amino acid uptake by activation of the Ca2+ -dependent K+ channel in the Ehrlich ascites tumor cell. 1982

M Valdeolmillos, and J García-Sancho, and B Herreros

The activation of Ca2+ -dependent K+ channel by propranolol or by ascorbate-phenazine methosulphate stimulates Na+ -dependent transport of alpha-aminoisobutyric acid. This stimulation arises from a membrane hyperpolarization due to the specific increase of membrane K+ conductance. The same treatment does not modify the Na+ -independent uptake of the norbornane amino acid.

D011188	Potassium	An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
D011433	Propranolol	A widely used non-cardioselective beta-adrenergic antagonist. Propranolol has been used for MYOCARDIAL INFARCTION; ARRHYTHMIA; ANGINA PECTORIS; HYPERTENSION; HYPERTHYROIDISM; MIGRAINE; PHEOCHROMOCYTOMA; and ANXIETY but adverse effects instigate replacement by newer drugs.

D002118	Calcium	A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
