Expression of CIP2A in benign prostatic hyperplasia and in prostate cancer. Immunohistochemical detection of CIP2A protein expression in benign prostatic hyperplasia specimens (A) and in prostate cancer specimens (B-C). The representative Gleason scores of 6 (B) and 9 (C) are presented. Diffuse, weak cytoplasmic staining of CIP2A was present in hyperplastic tissues, whereas the staining pattern in cancer cells showed coarsely granular cytoplasmic positivity. Magnification × 100, and in inserts × 400.
