Key result
Extracellular vesicle-encapsulated microRNAs protect against vascular calcification but are depleted in CKD rodent models.
Why the study?
Molecular mechanisms of cardiovascular-kidney-metabolic syndrome remain largely unknown, and validated prognostic markers are lacking.
MicroRNAs encapsulated in circulating small extracellular vesicles are being investigated as potential prognostic markers for cardiovascular and kidney outcomes in cardiovascular-kidney-metabolic (CKM) syndrome.
Adverse organ crosstalk among the kidney, cardiovascular system, and metabolic pathways has been conceptualized as the “cardiovascular–kidney–metabolic (CKM) syndrome”. Its molecular mechanisms remain largely unknown, and validated prognostic markers are lacking. We previously identified a set of micro (mi) RNAs encapsulated in circulating small extracellular vesicles (cEVs) that are physiologically protective against vascular calcification and are depleted in blood from chronic kidney disease (CKD) model rodents.
