To clarify the involvement of peroxisome proliferator-activated receptors (PPARs) in atherosclerotic plaque formation, we investigated the expression patterns of mRNA and protein of PPARalpha and PPARgamma in human aorta. Atheromatous plaque, fatty streak, and diffuse intimal thickening (DIT) were separated macroscopically, and each sample was divided into halves. Half of them were used for analysis of mRNA expression with reverse transcription-polymerase chain reaction and the others were used for histologic analysis. Both PPARalpha and PPARgamma mRNA were detected in all atheromatous plaques, all fatty streaks, and in some DIT. However, expressions of PPARalpha and PPARgamma were obviously less frequently found in DIT than in atheromatous plaques, and the intensity of these expressions was stronger in the atheromatous plaques than in the DIT. Compared with PPARalpha, PPARgamma mRNA was expressed more frequently in atheromatous plaques. In atheromatous plaques, PPARgamma mRNA was expressed independently, whereas PPARalpha mRNA was coexpressed with PPARgamma. PPARgamma protein was obviously found in the nuclei of endothelial cells, macrophages, mononuclear cells, and smooth muscle cells in the aortic intima. These results suggest that expressions of PPARalpha and PPARgamma in human aortic wall are involved in atherogenesis from the early stages.
