Expression of the protein damage marker, nitrotyrosine, in normal, BH, DCIS and IBC tissue. A. Tissues were subjected to IHC using a nitrotyrosine-specific antibody. Representative slides are shown at 40× magnification. B. The relative mean intensity was determined from 6-8 images for each BH (n = 13), DCIS (n = 13) or IBC (n = 23) section and is shown graphically. The intensity of normal mammary tissue is equal to one (dashed line).
