Figure 3. miR-3574 attenuates IH-induced cells injury in H9c2 cardiomyocytes. H9c2 cells were exposed to IH after transfection of miR-3574 mimics, and negative control. (A) Cell viability. (B, C) The expression of apoptosis-related proteins. NC: negative control. IH: intermittent hypoxia. Data are represented as the mean ± SD from three independent experiments. * p < 0.05, ** p < 0.01.
