Immunohistochemical analysis of Dicer protein expression in normal and breast cancer tissues. (A) Low-intensity staining in the cytoplasm of epithelial luminal normal breast cells. Non-specific staining of mast cells. (B) Low-intensity staining in the cytoplasm of infiltrating ductal carcinomatous cells. (C) High-intensity staining in the cytoplasm of infiltrating ductal carcinomatous cells. Images are shown at magnification, × 40 (panels A–C).
