Differential antagonistic effects of finerenone and spironolactone on the aldosterone transcriptome in human kidney cells.

Project description:Aldosterone, the main mineralocorticoid hormone in humans, controls, via gene transregulation, various renal functions including water and sodium reabsorption and potassium excretion. Dysregulations in the aldosterone signaling pathway lead to renal dysfunctions, including chronic kidney disease and renal fibrosis, that can be prevented or treated with mineralocorticoid receptor antagonists (MRAs). To understand the global effects of aldosterone on the human renal transcriptome, and how it is antagonized by the MRAs spironolactone and finerenone, we used RNA-sequencing on a human kidney cells HK-GFP-hMR. Our data provide the first complete transcriptome for aldosterone on a human renal cell line and support at the RNA level the benefit of finerenone for the treatment of kidney injury and fibrosis.

RNA-seq of the whole retina of rat intravitreally injected with aldosterone

Project description:The mineralocorticoid receptor is expressed in the rat and human retina. We previously showed that intravitreal injection of aldosterone in rat eyes induced retinal œdème and choroidal vasodilation and permeability through regulation of ion/water channels (Zhao et al. Faseb J, 2009; Zhao et al. J Clin Invest 2012). Illicit activation of MR induces inflammation, oxidative stress and tissue remodeling in cardiovascular and renal diseases independent of hypertension. We performed a full transcriptomic study destinated to identify genes regulated by aldosterone in the whole retina of rat.

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.

Calcineurin increases expression of aldosterone synthase via dephosphorylation of NFATc4

Project description:The mineralocorticoid hormone, aldosterone, is secreted by the adrenal zona glomerulosa (ZG) in response to high plasma K+ and hypovolemia and promotes renal Na+ reabsorption and K+ secretion. Hence, the regulation of aldosterone secretion is critical for the control of ion homeostasis and blood pressure. While the kinase pathways regulating aldosterone production are well studied, little is known about the involved phosphatases. Using the human adrenocortical carcinoma cell line NCI-H295R, we found that the mRNA expression of the aldosterone synthase increases significantly within 6 hours after K+ exposure. This increase was inhibited in a dose-dependent manner by the calcineurin inhibitors tacrolimus and cyclosporine A. Calcineurin (Cn) is a serine-threonine-specific, Ca2+ and CaM-activated protein phosphatase essential for lymphocyte, neuronal and cardiac function. The physiologic role of Cn in the ZG cells and the molecular pathways by which Cn regulates the K+-stimulated secretion of aldosterone are unknown. To answer these questions, we stimulated NCI-H295R cells with K+ with or without Tacrolimus and studied the phosphorylation pattern of cytoplasmic proteins by phospho-proteomics. We generated a map of the changes in the Ser/Thr phosphorylation in adrenocortical cells upon stimulation with K+ and identified Cn-regulated phosphoproteins.

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.

Expression data from human primary skeletal muscle myotubes treated with aldosterone, spironolactone, or vehicle.

Project description:To test for a function effect of mineralocorticoid receptor modulation in skeletal muscle, global gene expression analysis was conducted on human myltubes treated with a mineralocorticoid receptor agonist or antagonist. 9 total samples were analyzed. 3 biological replicates for each of the following treatment groups were included: 1) aldosterone; 2) spironolactone; 3) vehicle (ethanol). Pairwise comparison between groups were carried out and a fold-change ≥2 were selected.

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.
