Outline of Final Research Achievements

The process of progression of atherosclerosis during childhood and its molecular mechanisms are not fully understood. We aimed to examine the developmental changes of atherosclerosis using vascular tissue samples ranging in age from 0 to 71 years old. In human coronary arterial smooth muscle cells, prostaglandin E receptor EP4 was highly expressed among EP receptors. Physiological intimal thickening was observed from newborn infants. We analyzed ApoE-/- EP4+/+ and ApoE-/- EP4+/- mice and found that EP4 deficiency inhibited atherosclerotic plaque formation. These data suggested that EP4 contributes to progression of atherosclerotic remodeling from childhood.
