Tissue-specific quantification and localization of androgen and estrogen receptors in prostate cancer.

ABSTRACT: Androgens and estrogens, working together, promote prostate cancer (PRCA) initiation and progression, with androgens acting via androgen receptor (AR) and estrogens acting primarily through estrogen receptor α (ERα). While the interplay between these steroid hormones has been established, the interaction between steroid hormone receptors in prostatic disease remains unstudied. The goal of this study was to objectively determine the incidence, stage specificity, and tissue/cell type specificity of AR and ERα expression, both independently and simultaneously, during the progression of PRCA. Using multiplexed immunohistochemistry and multispectral imaging analysis, AR, ERα, and smooth muscle α-actin expression was detected and quantitated in benign prostate tissue (BPT), high-grade prostatic
