Circulating microRNA-126 increases after different forms of endurance exercise in healthy adults.

Abstract

MicroRNAs (miRNAs) are small non-coding molecules regulating gene expression. Recently circulating miRNAs could be detected in the plasma, serving as novel biomarkers. Different forms of exercise mobilize progenitor cells from the bone marrow, helping in tissue repair. Data of different forms of exercise on endothelial cell damage are lacking. The aim of the study was to evaluate the impact of different exercise modalities on the plasma concentration of miRNA-126, as a marker for endothelial damage.
