DOCA treatment and salt depletion of mice increases serum FGF23 concentration.
In osteoblasts aldosterone enhances and spironolactone decreases Ca2+ entry (SOCE).
Aldosterone increases FGF23 transcript levels in osteoblasts.
The effect of aldosterone is blunted by mineralocorticoid receptor blockers.
The aldosterone effect is blunted by inhibition of SGK1, NFκB or Ca2+ channels.
