Light micrographs of a myocytes in hematoxylin–eosinstained sections and c interstitial and e perivascular fibrosis in Sirius red-stained sections of the LV wall in representative wild-type and Ahr^−/− mice treated with Ang II and fenofibrate. Scale bars, 100 μm. Quantitative analysis of b myocyte cross-sectional area, c interstitial fibrosis, and f perivascular fibrosis and in the left ventricle of wild-type and Ahr^−/− mice treated with Ang II and fenofibrate. Data are mean ± SEM of six mice per group. *P < 0.05 vs. wild-type control mice; ^#P < 0.05 vs. wild-type Ang II mice; ^†P < 0.05 vs. Ahr^−/− Ang II mice
