Figure 4:Overexpression of HSP60 and α-B crystallin in infiltrating ductal carcinoma tissues of the breast (Hamrita et al., 2008). Formalin-fixed, paraffin-embedded sections were immunostained with rabbit polyclonal antibody against α-B crystallin or antibody against HSP60. A strong staining (brown) in tumor cells has been observed, whereas α-B crystallin and HSP60 were expressed at lower levels in normal epithelial cells. a, c, d: HSP60 expression in IDCA tissues (a: 100× magnification; c,d:400× magnification). b: HSP60 expression in non-tumor tissues (100× magnification). E-h: α-B crystallin expression in IDCA tissues. i, j: α-B crystallin expression in nontumor tissues (400× magnification).
