- Researchers utilized several databases to identify targets of finerenone and analyzed their interactions with a focus on disease-related targets, employing protein-protein interaction networks and enrichment analysis techniques.
- The study identified 111 potential cardiorenal targets and pointed to key mechanisms involving lipids, atherosclerosis, and diabetic complications, while confirming finerenone's protective effects through histopathological studies and protein expression analysis in diabetic mice.
Article Abstract
Introduction: Large prospective trials have demonstrated that finerenone could reduce the risk of cardiovascular death and progression of renal failure among patients with chronic kidney disease associated heart failure and/or type 2 diabetes mellitus (T2DM). The aim of this study was to explore the molecular mechanism of finerenone in the treatment of cardiorenal diseases through network pharmacology.
Methods: The STITH, SwissTargetPrediction, PharmMapper, DrugBank, and ChEMBL databases were used to screen the targets of finerenone. The disease-related targets were retrieved from the DisGeNET, GeneCards, CTD, OMIM, and MalaCards databases. The protein-protein interaction (PPI) network was conducted with STRING database and Cytoscape software. The clusterProfiler R package was used to perform Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. The interactions of key targets and finerenone were analyzed by molecular docking in Autodock software. Diabetes mellitus was induced by intraperitoneal injection of streptozotocin. Histopathology of myocardial and renal tissues was observed by hematoxylin-eosin (HE) staining, and detection of protein expressions was conducted using Western blotting.
Results: A total of 111 potential cardiorenal targets of finerenone were identified. The main mechanisms of action may be associated with lipids and atherosclerosis, fluid shear stress and atherosclerosis, AGE-RAGE signaling pathway in diabetic complications, and diabetic cardiomyopathy. The hub targets demonstrated by the PPI network were CASP3, ALB, MMP9, EGFR, ANXA5, IGF1, SRC, TNFRSF1A, IL2, and PPARG, and the docking results suggested that finerenone could bind to these targets with high affinities. HE staining revealed the cardiorenal protection of finerenone on diabetic mice. In addition, the protein expressions of CASP3 and EGFR were increased while ALB was decreased in myocardial and renal tissues in diabetic mice compared with control mice, which were reversed by finerenone.
Conclusion: This study suggested that finerenone exerts cardiorenal benefits through multiple targets and pathways.
