Research Abstract

We have investigated the molecular mechanisms of aldosterone-induced tissue injury using neuronal and vascular smooth muscle cells. We found that aldosterone induced the genes related to ion-channels, Ca-regulated transcription factors, inflammation, and rennin-angiotensin system. We also found that the co-expression of gluocorticoid receptor and/or steroid receptor cofactor(s) is necessary for aldosterone/MR mediated gene transcription.
