Noxa1deletion attenuates ROS levels and atherogenesis inApoe-/-andLdlr-/-mice fed a Western diet. A, Representative images and quantification of en face oil red O-positive area of aortas (mean±SEM, n = 12). B, Representative images and quantification of lesion volume of oil red O stained aortic root sections. Data presented was atherosclerotic lesion volume integrated from serial transverse sections (mean±SEM, n = 12). C, Representative images and quantification of DHE fluorescence in aortic root sections. Data presented was integrated density of DHE fluorescence (mean±SEM, n = 8). D, Representative images and en face analysis of oil red O-positive area of aortas (mean±SEM, n = 10). E, Representative images and quantification of lesion volume of oil red O stained aortic root sections. Atherosclerotic lesion volume was integrated from serial transverse sections (mean±SEM, n = 9). F, Representative images and quantification of DHE fluorescence in aortic root sections (mean±SEM, n = 9). Scale is 100 µm.
