Completed

1) To interrogate whether elevated miR-34a and reduced miR-883b in adipose tissues are important contributors to obesity-associated adipose tissue inflammation, vascular dysfunction and atherosclerosis in rodents and humans; 2) To investigate the molecular mechanism by which miR-34a and miR-883b fine-tunes macrophage infiltration and polarization in adipose tissues; 3) To elucidate how the two small lipid-binding adipokines (A-FABP and lipocalin-2) mediate obesity-induced M2→M1 macrophage polarization and vascular dysfunction in rodents; 4) To validate whether A-FABP and lipocalin-2 are viable therapeutic targets for obesityinduced adipose inflammation, endothelial dysfunction and atherosclerosis in pigs.
