Although prolactin's action on the mammary gland is well known, it is also found in the circulation of males and its receptor (PRLR) is expressed in the prostate. Furthermore, studies have supported the contribution of the canonical PRLR-Jak2-Stat5a/b pathway to prostate cancer tumorigenesis and progression. In this Review, the authors discuss the data regarding the role of prolactin in the prostate and consider the therapeutic potential of targeting prolactin signaling pathways in the treatment of advanced prostate cancer.
