Aldosterone increases NHE-1 expression and induces NHE-1-dependent hypertrophy in neonatal rat ventricular myocytes.

We determined the effect of 24-hour aldosterone (100 nmol/L) treatment on hypertrophic responses in rat neonatal ventricular myocytes and the possible role of Na+-H+ exchange isoform 1 (NHE-1). Aldosterone significantly increased cell size by 61% and expression of atrial natriuretic peptide by 2-fold. NHE-1 mRNA expression and protein abundance were significantly increased, and intracellular Na...

Na+/H+ exchangers, NHE-1 and NHE-3, of rat intestine. Expression and localization.

Na-H exchange (NHE) is one of the major non-nutritive Na absorptive pathways of the intestine and kidney. Of the four NHE isoforms that have been cloned, only one, NHE-3, appears to be epithelial specific. We have examined the regional and cellular expression of NHE-3 in the rat intestine. NHE-3 message in the small intestine was more abundant in the villus fractions of the small intestine than...

High-Mobility Group Box 1 Induces Calcineurin-Mediated Cell Hypertrophy in Neonatal Rat Ventricular Myocytes

Cardiac hypertrophy is an independent predictor of cardiovascular morbidity and mortality. In recent years, evidences suggest that high-mobility group box 1 (HMGB1) protein, an inflammatory cytokine, participates in cardiac remodeling; however, the involvement of HMGB1 in the pathogenesis of cardiac hypertrophy remains unknown. The aim of this study was to investigate whether HMGB1 is sufficien...

NHE-1 and NHE-6 activities: ischemic and reperfusion injury.

The study 1 published in this issue of Circulation Research showing that a null mutation of NHE-1 improves the tolerance of the heart to ischemia and reperfusion (I/R) is an important contribution for the following reasons: (1) In the animals with null mutation, contracture during the ischemic period was less and ATP levels were preserved compared with wild-type animals. This observation, on th...

The obesity-associated peptide leptin induces hypertrophy in neonatal rat ventricular myocytes.

One of the major manifestations of obesity is increased production of the adipocyte-derived 16-kDa peptide leptin, which is also elevated in heart disease, including congestive heart failure. However, whether leptin can directly alter the cardiac phenotype is not known. We therefore studied the effect of leptin as a potential hypertrophic factor in cultured myocytes from 1- to 4-day-old neonata...
