Figure 2. IH reduces miR-3574 expression, and miR-3574 is differentially expressed in H9c2 cardiomyocytes after cell transfection. (A) The expression of miR-3574 was detected by RT-qPCR. (B) Cells were transfected with miR-3574 inhibitor, miR-3574 mimics, and scrambled control. Relative miR-3574 expression was normalized to U6. IH: intermittent hypoxia. Data are represented as the mean ± SD from three independent experiments. * p < 0.05, ** p < 0.01.
