Cardiac aldosterone regulated genes in mice with cardiomyocytes targeted mineralocorticoid receptor overexpression (MR-Cardio mice) and their controls (Ctrl mice)

ABSTRACT: Inappropriate mineralocorticoid receptor (MR) activation is involved in cardiac diseases. The mechanisms are still unclears. Mice overexpressing MR in cardiomyocytes (MR-Cardio) and their controls (Ctrl) were treated for 7 days with aldosterone and a whole genome microarray analysis was performed.

Cardiac aldosterone and corticosterone regulated genes in mice with cardiomyocytes targeted mineralocorticoid receptor overexpression (MR-Cardio mice) and their controls (Ctrl mice)

Project description:Inappropriate mineralocorticoid receptor (MR) activation is involved in cardiac diseases. MR binds aldosterone, but also glucocorticoids; the identity of the ligand responsible for the deleterious effects of cardiac MR activation is still unclear. Mice overexpressing MR in cardiomyocytes (MR-Cardio) and their controls (Ctrl) were treated for 7 days with aldosterone or corticosterone and a whole genome microarray analysis was performed.

Cistrome of the Aldosterone-activated Mineralocorticoid Receptor in Human Renal Cells

Project description:Aldosterone, the main mineralocorticoid hormone in Humans, has a major role in maintaining the hemo-electrolytique homeostasis, by acting in the distal part of nephron. This steroid hormone mainly acts through its binding to a ligand-induced transcription factor, the mineralocorticoid receptor (MR). MR binds to specific genomic sequences, where it recruits transcriptional coregulators, to activate or repress target gene transcription. The aim of this work was to access the whole aldosterone-dependand MR target genes, by comparing sequenced data from aldosterone or vehicle-treated samples. Anti-MR ChIP-seq in Human Kidney GFP-hMR cells treated with vehicle or Aldosterone.

Aldosterone-inducible genes in mineralocorticoid receptor expressed human endothelial cell lines

Project description:To elucidate the aldosterone-regulated genes in vascular endothelial cells, we developed human endothelial cell line (EAhy926) stably expressing human mineralocorticoid receptor by retroviral system (MR-EAhy). Then gene expression profile of MR-EAhy stimulated with or without aldosterone was compared using DNA microarray analysis. MR-EAhy were serum-deprived for 24h with 0.2% dextran-coated charcoal-treated FBS, and then stimulated with or without aldosterone (10-9 M) for 6 hr. Then cells were harvested for RNA extraction.

Aldosterone-Regulated Expression Data in Mouse Aorta

Project description:The steroid hormone aldosterone plays a role in vascular function and disease. Aldosterone activates the mineralocorticoid receptor (MR), a ligand-activated transcription factor. MR have been found to be expressed in vascular cells and vessels. We used microarrays to identify the global programme of gene expression changes in mouse aortas treated with vehicle (DMSO) or aldosterone. Wild type C57Bl6 male mice were treated with spironolactone (20 mg/kg/day, an MR antagonist) for 5 days by Sub-cutaneous pellet to suppress basal MR-mediated gene expression. Aortas were then harvested and treated ex vivo in organ culture with vehicle or 100 nM aldosterone for 2, 4, or 8 hours. Three aortas were pooled for each timepoint and treatment, and three pooled biological replicates were performed.

Effect of Mineralocorticoid Receptor deletion on glucocorticoid signalling in the macropahge

Project description:Inappropriate excess of the steroid hormone aldosterone, which is a mineralocorticoid receptor (MR) agonist, is associated with increased inflammation and risk of cardiovascular disease. MR antagonists are cardioprotective and antiinflammatory in vivo, and evidence suggests that they mediate these effects in part by aldosterone- independent mechanisms. We used affymetrix to characterize the effect of Mineralocorticoid Receptor deletion on macrophage transcriptional profile, and identify its requirement in normal glucocorticoid signalling. We isolated mouse peritoneal macrophages from Myeloid MRKO mice and Floxed Controls, cultured in the presence or absence of corticosterone. RNA was extracted for Affymetrix cDNA hybridization. Each sample was pooled from experiments performed in triplicate.
