Expression data from mDCT cell-line over-expressing hMR

Target gene of mineralocorticoid receptor (MR) is comparatively unknown, although distal convoluted tubule (DCT) expresses MR in in vivo. We used microarray and immortalized murine DCT cell-line overexpressing human MR with treatment of aldosterone to elucidate target genes of MR in DCT. mDCT overexpresses human MR by lipofection and is treated for 3 hours with ethanol (g1), or 10^-9 M aldosterone (g2), or 10^-7 M aldosterone (g3), or 10^-7 M aldosterone with pretreatment of 5 x 10^-6 M spironolactone (g4) for 2 hours.
