Fig 1: HOXA9 inhibitors alleviate damage induced by AS via downregulating PF4 and E-selectin/VCAM-1 proteins in coronary arteries and thoracic aorta samples. (A) Results of western blotting. Relative expression levels of (B) HOXA9, (C) PF4, (D) E-selectin and (E) VCAM-1 normalized to ß-actin. (F) Association between HOXA9, PF4 and E-selectin/VCAM. **P<0.01 vs. NC group; ##P<0.01 vs. AS group; &&P<0.01 as indicated; AS, atherosclerosis; NC, normal control; si, small interfering; HOXA9, homeobox A9; PF4, platelet factor-4; VCAM-1, vascular cell adhesion molecule-1.
