    Abstract Background: Conversion of adrenally produced dehydroepiandrosterone (DHEA) to the potent androgen dihydrotestosterone (DHT) is an important mechanism by which prostate cancer reaches castration resistance. At the start of this pathway is a branch point at which DHEA can be converted to Δ
    Methods: Prostate cancer cells (LNCaP cell line) were incubated with steroids (DHEA and Δ
    Results: The two reactions displayed very different saturation profiles, with only the 3βHSD-catalyzed reaction beginning to saturate within a physiological substrate concentration range. Strikingly, incubating LNCaP cells with low (in the ~10 nM range) concentrations of DHEA resulted in a large majority of the DHEA undergoing 3βHSD-catalyzed conversion to Δ
    Conclusion: Contrary to expectations from previous studies that used purified enzyme, cellular metabolism of DHEA by 3βHSD begins to saturate in the physiological concentration range, suggesting that fluctuations in DHEA concentrations could be buffered at the downstream active androgen level.

    Abstract Activation of the androgen receptor (AR) and AR-driven transcriptional programs is central to the pathophysiology of prostate cancer. Despite successful translational efforts in targeting AR, therapeutic resistance often occurs as a result of molecular alterations in the androgen signaling axis. The efficacy of next-generation AR-directed therapies for castration-resistant prostate cancer has provided crucial clinical validation for the continued dependence on AR signaling and introduced a range of new treatment options for men with both castration-resistant and castration-sensitive disease. Despite this, however, metastatic prostate cancer largely remains an incurable disease, highlighting the need to better understand the diverse mechanisms by which tumors thwart AR-directed therapies, which may inform new therapeutic avenues. In this review, we revisit concepts in AR signaling and current understandings of AR signaling-dependent resistance mechanisms as well as the next frontier of AR targeting in prostate cancer.

    Abstract In the treatment of metastatic prostate cancer, resistance to hormonal therapy is a major obstacle. With antiandrogen therapies that suppress androgen signaling through the androgen receptor (AR), the primary driver of prostate cancer, some malignancies are able take advantage of the closely related glucocorticoid receptor (GR). Escape from AR dependency often involves a simple functional switch from 1 steroid receptor to another. Recent research efforts have outlined the mechanism enabling this switch, which involves alterations in glucocorticoid metabolism that occur with antiandrogen therapy to increase tumor tissue glucocorticoids and enable GR signaling. Targeting this mechanism pharmacologically by blocking hexose-6-phosphate dehydrogenase shows promise in normalizing glucocorticoid metabolism and restoring responsiveness to antiandrogen therapy. This perspective reviews what we have learned about this resistance mechanism, examines potential implications, and considers how this knowledge might be harnessed for therapeutic benefit.
