  • Title: [The hormonal regulation of mRNA Na,K-ATPase expression in rat kidneys in postnatal ontogeny].
    Author: Logvinenko NS, Khlebodarova TM, Solenov EI, Ivanova LN, Broude NE, Monastyrskaia GS.
    Journal: Tsitologiia; 1991; 33(11):18-25. PubMed ID: 1668047.
    Abstract:
    A study was made of effects of aldosterone, aldosterone+dexamethasone, and aldosterone+spironolactone on Na,K-ATPase mRNA expression in renal cortex of adult and 10 day old rats, when kidney is not sensitive to the hormone injection. It is shown that hormonal induction of synthesis of Na,K-pump mRNA occurs in the early postnatal period apart from mineral corticoid receptors. It seems probable that aldosterone exerts its action in 10 day old rats by interaction with glucocorticoid receptors inducing synthesis of different amounts of alpha- and beta-subunits of Na,K-ATPase.
