To assess the potential physiological activity of PPAR ligands on cardiac muscular cells, the effects of PPAR\u03b1 agonist, WY-14, 643, on both rat hearts and a rat cardiomyocyte cell line(H9c2 cells)were investigated. Male F344 rats were fed a diet containing WY-14, 643 at a concentration of 100 ppm for 26 weeks. Cardiac muscular hypertrophy was revealed by morphometric analysis in which the diameter of the muscular fibers in WY-14, 643-treated rats was larger than those of control rats. Using H9c2 cells in vitro, the protein content per cell was increased in a dose-dependent manner with the treatment of WY-14, 643. The transcription of myosin light chain-2(MLC-2), a parameter of myocardial hypertrophy, was increased in H9c2 cells transfected with the rat MLC-2/luciferase fusion gene by WY-14, 643 as well as other peroxisome proliferators, clofibrate and di(2-eth-ylhexyl)phthalate. In addition, accumulation of myosin light chain protein was confirmed in H9c2 cells treated with W\\\u003cbr/\u003eY-14, 643 at 10 \u03bcg/ml for 7 days or more by immunohistochemistry. These results suggest that PPAR\u03b1 ligands have a potential to regulate MLC-2, which is a contractile protein in cardiomyocytes and may play a part of role in the pathogenesis of cardiac hypertrophy.", "subitem_description_type": "Abstract"}]}, "item_12_relation_54": {"attribute_name": "\u7570\u7248\u3067\u3042\u308b", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf",
