Bulk mRNA-seq data from wild-type and prostate cancer-developing mice reveal a reprogramming of the estrogen and androgen responses after carcinogenesis.

Sex hormones are necessary for the development and functions of the normal prostate as well as for the initiation and progression of prostate tumors. Indeed, androgens and estrogens can activate their respective nuclear receptors to modulate the expression of multiple genes and pathways in prostate cells. Nevertheless, the androgen and estrogen responses in the normal prostate, and the transcriptomic changes occurring after carcinogenesis, remain poorly understood. Here, wildtype mice and transgenic mice that spontaneously develop prostate cancer (C57BL/6J PB-Cre4; ) were castrated to ensure hormone deprivation. After three days, animals received injections of testosterone and/or estradiol. After one day, the prostates were harvested, and RNA was purified for sequencing. Sequencing data were then analyzed to study transcriptional modulations following hormonal exposures in normal and tumoral murine prostates. New analyses can be carried out with specific fold-change thresholds for gene expression, or with different pair-wise combinations between conditions (treatments and/or mouse models). Together, the data generated herein are a useful tool to study hormonal transcriptional responses in prostate and prostate cancer biology.
