The p53 homologue p63 encodes
for different isotypes able to either transactivate p53
reporter genes (TAp63) or act as
p53-dominant-negatives (
Np63). p63 is
expressed in the basal cells of many epithelial organs and its germline
inactivation in the mouse results in agenesis of organs such as skin
appendages and the breast. Here, we show that prostate basal
cells, but not secretory or neuroendocrine cells,
express p63. In addition, prostate basal cells in culture
predominantly express the
Np63
isotype. In contrast, p63
protein is not detected in human prostate adenocarcinomas.
Finally, and most importantly,
p63(-/-) mice do not develop the prostate. These
results indicate that p63 is required for prostate development and
support the hypothesis that basal cells represent and/or include
prostate stem cells. Furthermore, our results show that p63
immunohistochemistry may be a valuable tool in the differential
diagnosis of benign versus malignant prostatic lesions.
