(a) Effect on height of dorsolateral prostatic epithelium. After aged rats were treated with 10–90 μg/kg BPA for 3 months, BPA significantly increased the height of DLP epithelium in a dose-dependent way, *P < 0.01, compared with the vehicle controls. BPA: bisphenol A. (b) The expression of the PCNA in DLP. The expression of PCNA was increased obviously in BPA-treated groups. *P < 0.05: compared with the vehicle controls; *P < 0.01, compared with the vehicle controls. BPA: bisphenol A.
