miR-17-3p was significantly downregulated in peripheral blood exosomes from patients with cardiac I/R injury. (a) The morphology of the peripheral blood exosomes was detected by TEM (n = 3, bar = 100 μm). (b) The concentration and diameters of exosome particles were determined using the NTA assay (n = 3). (c) The expression of exosomal markers (CD63, CD9, and TSG101) was evaluated by Western blotting (n = 3). (d) The expression of exosomal miR-17-3p in the peripheral blood was measured by qRT-PCR (n = 15). U6 was used as a control. Data are presented as the mean ± SD; ∗∗∗∗P < 0.001, I/R injury vs. control.
