- W40698093 abstract "The cardiac subtype of Na+/H+ exchanger (NHE-1) plays an important role in the regulation of intracellular pH (pHi) and also can be a major route for Na+ influx. Although intracellular ATP is required for the optimal function of NHE-1, the regulation of the exchanger by ATP is less well characterized. This study was designed to investigate which intracellular ATP generated by oxidative phosphorylation or by glycolysis is dominant for the activation of NHE-1 in intact cardiac myocytes. Isolated guinea pig ventricular myocytes were loaded with the pHi-sensitive fluorescent indicator, 2'-7'-bis(carboxyl)-5',6'-carboxy fluorescein (BCECF), and exposed to 20 mM 2-deoxyglucose (2-DG) or 2 mM sodium cyanide (CN) to inhibit glycolysis or oxidative phosphorylation, respectively. The activity of NHE-1 was estimated with pHi recovery following transient application of 15 mM NH4Cl (NH4Cl prepulse). After the NH4Cl prepulse, pHi decreased from 7.00 +/- 0.03 (mean +/- S.E.) to 6.60 +/- 0.06 and recovered to 6.94 +/- 0.13 at 10 min (n = 7). The pHi recovery was suppressed in the presence of 2-DG (6.67 +/- 0.05, p < 0.01, n = 7), but was not changed in the presence of CN (6.88 +/- 0.18, n = 6). Since there was no difference in the intrinsic H+ buffering power, the estimation of the net acid efflux demonstrated that the activity of NHE-1 was significantly depressed in 2-DG. The inhibitory effect of 2-DG was not due to more extensive depletion of global intracellular ATP or secondary to the change in either intracellular Na+ or Ca2+ concentration. We concluded that ATP generated by glycolysis rather than by oxidative phosphorylation is essential to activate NHE-1 in ventricular myocytes." @default.
