dc.description.abstractThe aim of this study was to investigate whether the presence of endogenous estradiol alters the effects of a high-fat (HF) diet on activity/expression of the cardiac Na+/K+-ATPase, via PI3K/IRS and RhoA/ROCK signalling cascades in female rats. For this study, female Wistar rats (8 weeks old, 150-200 g) were fed a standard diet or a HF diet (balanced diet for laboratory rats enriched with 42% fat) for 10 weeks. The results show that rats fed a HF diet exhibited a decrease in phosphorylation of the alpha(1) subunit of Na+/K+-ATPase by 30% (p LT 0.05), expression of total alpha(1) subunit of Na+/K+-ATPase by 31% (p LT 0.05), and association of IRS1 with p85 subunit of PI3K by 42% (p LT 0.05), while the levels of cardiac RhoA and ROCK2 were significantly increased by 84% (p LT 0.01) and 62% (p LT 0.05), respectively. Our results suggest that a HF diet alters cardiac Na+/K+-ATPase expression via molecular mechanisms involving RhoA/ROCK and IRS-1/PI3K signalling in female rats.en
