1 Accordingly, we determined the contribution of NHE-1 to cardiac glycoside-induced hypertrophy. Glycosides solute carrier family 9 member A1 Rattus norvegicus
2 Conversely, both glycosides increased NHE-1 expression in cardiomyocytes by approximately two-fold and significantly increased intracellular sodium concentrations by more than 60% (P < 0.05). Glycosides solute carrier family 9 member A1 Rattus norvegicus
3 CONCLUSION: When taken together, these studies show that NHE-1 inhibition attenuates the hypertrophic effect of cardiac glycosides without affecting inotropic parameters and suggest a possible approach to limiting glycoside-induced hypertrophic responses while preserving therapeutic, i.e. inotropic, actions.
