dc.description.abstractThe aim of this study was to investigate in vivo effects of estradiol on Na+/K+-ATPase activity/expression in high fat (HF) diet fed rats. Adult male Wistar rats were fed normally (Control, n = 7) or with a HF diet (Obese, n = 14) for 10 weeks. After 10 weeks, half of the obese rats were treated with estradiol (Obese + Estradiol, n = 7, 40 mu g/kg, i.p.) as a bolus injection and 24 h after treatment all the rats were sacrificed. Estradiol in vivo in obese rats in comparison with obese non-treated rats led to a statistically significant increase in concentration of serum Na+ (p LT 0.05), Na+/K+-ATPase activity (p LT 0.01), expression of alpha 1 (p LT 0.01) and alpha 2 (p LT 0.05) subunit of Na+/K+-ATPase, both PI3K subunits p85 (p LT 0.01), p110 (p LT 0.05), and association of IRS-1 with p85 (p LT 0.05), while significantly decrease expression of AT1 (p LT 0.05) and Rho A (p LT 0.01) proteins. Our results suggest that estradiol in vivo in pathophysiological conditions, such as obesity accompanied with insulin resistance stimulates activity and expression of Na+/K+-ATPase by a mechanism that involves the participation of IRS-1/PI3K/Akt signaling. In addition, the decreasing level of AT1 and Rho A proteins estradiol probably attenuates the detrimental effect of obesity to decreased IRS-1/P13K association and consequently reduce Na+/K+-ATPase activity/expression.
