BACKGROUND Membrane transport of choline cations is elevated in renal failure in erythrocytes and cerebral tissue but the origins and clinical importance of this are unknown. METHODS The membrane transport changes have been characterized using erythrocytes from patients on maintenance haemodialysis (HD), patients on continuous ambulatory peritoneal(More)
Na(+)-dependent phosphate uptake by rat hepatocytes in primary culture is inhibited in a time-dependent fashion by cyclic AMP and by the myristate, acetate ester of phorbol. After incubation for 15 min at 37 degrees C with 10(-7) M dibutyryl cAMP, the Vmax of transport is decreased from 0.52 to 0.23 nmol Pi/min per mg protein but the Km value of(More)
