Micro RNAs (miR) are short non-coding RNAs that regulate several genes under pathophysiological conditions. Accumulating evidence suggest the involvement of miR in atherogenesis. However, limited information is available about atherogenic miR and the underling mechanisms by which miR affect atherogenesis. Our data shows that 12 weeks of western diet (WD) in LDL receptor-knockout (LDLR-KO) mice upregulated 99 and downregulated 50 miR in the aorta. Among the 41 differentially expressed miR associated with macrophage inflammation and apoptosis, expression of micro RNA-21 (miR-21) was increased by 1.4-fold (P
