Figure 1. MicroRNA-30a-3p decreased in the restenotic ASO artery. (A) SM-α-actin and microRNA-30a-3p were stained in ASO and normal vascular sections (n=8); We used DAPI to stain the nuclei. (A, B) The IOD of the microRNA-30a-3p-stained vascular sections was calculated and compared. (C) Relative microRNA-30a-3p levels in ASO and normal arteries (qRT-PCR, n=8). (D) Relative microRNA-30a-3p levels in the three layers of ASO arteries (qRT-PCR, n=8). Scale, 200 μm; ***=0.001.
