MicroRNA-146a (miR-146a) in the vasculature restrains endothelial cell (EC) activation and atherosclerosis. A, Schematic of lethally irradiated Ldlr−/− or double knockout (DKO) mice given bone marrow transplantation (BMT) from wild-type (WT BM) donors followed by high cholesterol diet (HCD) for 12 wk. B, Circulating proinflammatory markers, soluble intercellular adhesion molecule-1 (sICAM-1), IL-6 (interleukin-6), and TNF-α (tumor necrosis factor-α), measured by ELISA (n=5–8). C, Circulating cholesterol, high-density lipoprotein (HDL), triglycerides (TG), low-density lipoprotein (LDL) and glucose levels after 12 wk of HCD (n=5). D, Quantification of spleen weight after 12 wk of HCD (n=12–15). E, Fluorescence-activated cell sorting (FACS) analysis of myeloid cells from spleen, BM, and peripheral blood (n=12–15). F, Gene expression in BM cells from BM transplanted animals (n=3–7). G, Percentage of Oil Red-O (ORO) region per aortic arch measured by en face staining (n=11–14). Representative images are shown to the right. Data on EC activation in the aorta are given in Online Figure VIII.
