bcl-2 is expressed in several epithelial tissues,2,3,9,12,13 including the prostatic epithelium.2,3 It is expressed in normal prostatic epithelium, in prostatic ducts and in prostatic tumors, as reported previously.13 The expression is more common in tumors that exhibit malignant features, such as the invasive growth type and high proliferation rate of cancer cells, although a previous analysis of a small cohort of cases has suggested no significant relationship between histological differentiation and the expression of bcl-2 protein.13 Here, BCL2 is linked to cancer.
