Prostate cancer is the most common cancer in males in the UK, with approximately 47,700 new cases diagnosed each year. The goal was to characterize androgen receptor gene (AR) amplifications and mutations detected in circulating tumor DNA (ctDNA) from patients with prostate cancer in relation to non‐AR gene alterations detected in the ctDNA landscape. The study included 892 patients with prostate cancer with AR alterations in ctDNA. 2015-07-06 · However, in the researchers’ previous clinical trial of 62 men with advanced prostate cancer, the 18 patients who were AR-V7–positive showed no reduction in PSA levels with hormonal therapies. 2020-08-19 · The sensitivity of AR-positive cells is due to a distal K79 methylation-marked enhancer in the MYC gene bound by AR and DOT1L not present in AR-negative cells. DOT1L inhibition leads to reduced MYC 2014-04-08 · AR-V7-positive patients had worse responses to enzalutamide compared with patients who had no AR-V7 mRNA detected in CTCs. PSA levels failed to drop in the blood of all 12 AR-V7-positive patients.

The study was funded by the Prostate Cancer Foundation. 3.1 Enzalutamide‐resistant prostate cancer cells express higher levels of AR‐V7.

We recently identified an AR-V7 positive patient who responded to Abiraterone. Thus, we hypothesized that a subgroup of patients might benefit from next generation ADT despite expression of AR-V7 in CTCs. 2020-08-19 2021-01-20 AR-V7 Associated With Poorer Outcomes in Castration-Resistant Prostate Cancer The presence of androgen receptor splice variant-7 mRNA in circulating tumor cells was associated with poorer outcomes for men with castration-resistant prostate cancer assigned to novel hormonal therapies. Emmanuel S. Antonarakis, MD Emmanuel S. Antonarakis, MD SRC-1 expression is associated with prostate cancer aggressiveness, and suppression of SRC-1 expression reduced growth and altered AR target gene regulation in prostate cancer cells . However, in a murine prostate cancer model, the role of SRC-1 is nonessential for carcinogenesis and different from the essential contribution of SRC-3, which is required for prostate cancer progression and 2021-04-06 Circulating tumor cell (CTC)-based androgen receptor splice variant-7 (AR-V7) testing was validated as a prognostic test for men with castration-resistant prostate cancer (CRPC) receiving hormone Importantly, an administration of DHT to mice bearing castrated xenograft of AR-positive prostate cancer cells for 12 h prior to radiation resulted in a tumor growth delay compared to radiation AR‐V7 signaling and β‐catenin signaling reciprocally regulate each other in JDCaP‐hr cells, and therefore, GSK3 inhibition can repress AR‐V7 transcriptional activity by accumulating intracellular β‐catenin. Notably, LY‐2090314 selectively inhibited the growth of AR‐V7‐positive prostate cancer cells in vitro.

Androgen deprivation followed by acute androgen stimulation selectively sensitizes AR-positive prostate cancer cells to ionizing radiation Mohammad Hedayati, Michael C. Haffner, Jonathan B. Coulter , Raju R. Raval, Yonggang Zhang, Haoming Zhou, Omar Mian, Emma J. Knight, Nina Razavi, Susan Dalrymple, John T. Isaacs , Aileen Santos, Russell Hales , William G. Nelson , Srinivasan Combination therapy with androgen receptor N‐terminal domain antagonist EPI‐7170 and enzalutamide yields synergistic activity in AR‐V7‐positive prostate cancer Yukiyoshi Hirayama Genome Sciences Centre, BC Cancer, Vancouver, BC, Canada Provides easy-to-interpret results (a positive or negative result).

2014-09-03 · The prostate-cancer cell lines that served as positive and negative controls for AR-V7 detection by means of RNA in situ hybridization are shown in Figure S6 in the Supplementary Appendix.

2014-02-01 In 2014, it was first reported that the detection of androgen receptor splice variant 7 (AR-V7) messenger RNA (mRNA) in circulating tumor cells (CTCs) isolated from the blood of patients about to start a new line of therapy for castration-resistant prostate cancer (CRPC) was associated with a lack of response to abiraterone and enzalutamide [ A critical unmet need in advanced prostate cancer (PCa) management is how to best sequence the available life-prolonging therapies to maximize clinical benefit for the individual patient and, in particular, to identify those men most likely to respond to a next-generation hormonal agent (abiraterone or enzalutamide) versus a taxane agent (docetaxel or cabazitaxel).

Taken together, our data suggest that the main mechanism of trichostatin A-induced cell death in AR-positive prostate cancer is inhibition of AR gene expression. The synergistic effect of simultaneous treatment with trichostatin A and doxorubicin is mediated via inhibition of AR expression, induction of protease activity, increased expression of p53, and proteolysis of p21.

ARD-69 potently inhibits cell growth in these AR-positive prostate cancer cell lines and is >100 times more potent than AR antagonists.
