TGFBR3 and coronary artery disorder: To further validate the expression of miR-513a-5p and TGFBR3, we extracted RNA from patients with coronary artery disease and healthy controls and performed qRT-PCR experiments for miR-513a-5p and TGFBR3, respectively, which showed increased expression of miR-513a-5p and significantly decreased expression of TGFBR3 in the blood of patients with coronary artery disease (Fig. 4E, F).
