| Summary |
Mineralocorticoids play a critical role in maintaining sodium and potassium homeostasis and pathophysiological processes including hypertrophy, inflammation and fibrosis. Mineralocorticoid antagonists (MRAs) have shown to protect from kidney and heart disease, however, their molecular mechanism of action is poorly understood. Here we performed single nuclei and bulk transcriptomics and chromatin accessibility analysis to characterize the mode of kidney protection by steroidal and non-steroidal MRA treatment in a rat model of mineralocorticoid-induced cardiorenal end-organ damage. We define mineralocorticoid sensitive cell types and gene network in the kidney. We show that in diseased kidneys specific proximal tubule cells develop an injured profibrotic phenotype expressing Spp1 and Il34. Nonsteroidal finerenone protects from profibrotic differentiation of proximal tubule cells. Profibrotic gene signature can classify human kidney tissue samples and predict prognosis. Our multi-omics approach elucidates target cell types and potential mechanisms of renal protection by finerenone.

| Overall design |
We provided three types of datasets of rat kidneys: (i) single nuclei RNA-seq as follows: 3 Control - 3 DOCA treated - 2 DOCA+Finerenone treated - 3 DOCA + Spironolactone treated, (ii) single nuclei ATAC-seq as follows: 1 Control - 1 DOCA treated - 1 DOCA+Finerenone treated - 1 DOCA + Spironolactone treated, and (iii) Bulk RNA-seq as follows: 4 Control - 4 DOCA treated - 4 DOCA+Finerenone treated - 4 DOCA + Spironolactone treated
