A study in humans demonstrated that the mir-590 was significantly negatively correlated with age in peripheral blood from physiologically unaffected individuals, with a correlation of -0.486 and a raw P value of 6.97E-07 [Meder et al. DOI:10.1373/clinchem.2014.224238]. A study in humans demonstrated that plasma exosomal miR-4516, miR-203, and SFRP1 levels were significantly elevated in acute myocardial infarction patients and exhibited high diagnostic efficiency, with exo-miR-4516 also correlating with coronary lesion severity [Liu et al. DOI:10.3892/mmr.2023.13010]. The literature also notes that the mir-590 is associated with cardiac function recovery post-AMI by inducing mitosis, as referenced in introductory discussions [Jia et al. DOI:10.3389/fcell.2022.861451].
