18715944 Leite-Dellova DC, Oliveira-Souza M, Malnic G, Mello-Aires M: Genomic and nongenomic dose-dependent biphasic effect of aldosterone on Na+/H+ exchanger in proximal S3 segment: role of cytosolic calcium. Am J Physiol Renal Physiol. 2008 Nov;295(5):F1342-52. Epub 2008 Aug 20.

Spironolactone, actinomycin D, or cycloheximide did not affect the effects of aldosterone (15- or 2-min pi) but inhibited the effects of aldosterone (1-h pi) on pHirr and on [Ca2+] i.
The data indicate a genomic (1 h, via MR) and a nongenomic action (15 or 2 min, probably via GR) on [Ca2+] i and on the basolateral NHE1 and are compatible with stimulation of the NHE1 by increases in [Ca2+] i in the lower range (at 10 (-12) M aldosterone) and inhibition by increases at high levels (at 10 (-6) M aldosterone) or decreases in [Ca2+] i (at 10 (-6) M aldosterone plus RU 486).

The altered activity of NHE1 was consistent with an increase of both transcription and translation of the antiporter, as the utilization of actinomycin D and cycloheximide significantly inhibited the upregulation of NHE1 induced by serum withdrawal.

NHE3 activity was not detected in IGF-1-treated cells that had been incubated with the protein synthesis inhibitor cycloheximide, although NHE1 activity was unaffected.
