Genomic and Non-genomic Effects of Aldosterone


The last two decades have witnessed a growing number of experimental observations regarding the mineralocorticoid physiopathology, leading to a new understanding of the molecular basis of the aldosterone-induced target organ damage. As a matter of fact, although it has long been known that the combined administration of mineralocorticoids and salt leads to extensive vascular lesions in the target organs, the recognition that aldosterone is able to induce direct toxic effects on the various cell types that make up the cardiovascular organ has built up recently. Moreover, non-genomic effects have been attributed to aldosterone, i.e. effects which do not depend on the activation of the cellular transcription machinery, whose physiopathologic relevance is still being investigated. These advances in our understanding of aldosterone physiopathology have shed light on the biological reasons which are at the base of the impressive results obtained in clinical trials of aldosterone antagonism.
