Immunohistochemical analysis of protein 4.1B expression in prostate cancer and benign prostatic glands. A and B: Heterogeneous expression of protein 4.1B in benign prostatic glands. Note stronger expression levels in basal cells (arrows) than in secretory epithelial cells. C-D: Comparison of 4.1B expression levels in tumor glands (TU) and corresponding benign prostatic glands (N): C and D: equivalent and slightly decreased, respectively, 4.1B expression in cancer cells compared to secretory cells of normal glands. Original magnifications: A, D, x200; B, x400; C, x100. E: negative control without primary antibody.
