Abstract
The expression of the mutant p53 tumor suppressor gene was evaluated in 33 human prostate carcinomas. Using an immunohistochemical method with monoclonal antibodies PAb 1801 and PAb 240, 26 (79%) tumors demonstrated positive immunostaining for mutant p53. Only areas of glandular tumor were positive, with adjacent stromal elements and areas of glandular hyperplasia being negative. The predominant staining pattern was cytoplasmic. This pattern may be related to p53 binding to certain heat shock proteins (HSP 72/73), as a monoclonal antibody to these proteins demonstrated a cytoplasmic location as well. These results demonstrate that abnormal p53 expression is a frequent event in prostate cancer.
