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.

Prostate Carcinoma + AR is altered in 15.78% of prostate carcinoma patients [ 4 ]. AR Positive is an inclusion criterion in 2 clinical trials for prostate carcinoma, of which 1 is open and 1 is closed.

These data indicate that CDK11p58is an anti-metastasis gene product in prostate cancer. Taken together, we demonstrate a new role for CDK11p58as an anti-metastasis gene in prostate cancer. A recent phase III trial of the MET kinase inhibitor cabozantinib in men with castration-resistant prostate cancer (CRPC) failed to meet its primary survival end point; however, most men with CRPC have intact androgen receptor (AR) signaling. AR‐V7‐positive metastatic prostate cancer is a lethal phenotype with few treatment options and poor survival. AR-independent prostate cancer cells can re-express AR protein through exogenous stimuli (in green) that block AR repression. Once re-activated, AR can re-sensitize those cells to ARSi.

1 and 2; ref. 4), we aimed to determine if exposure of AR-positive cells to supraphysiological levels of androgens for 6 hours (the point of maximal induction of DSBs, but absence of significant androgen mediated cell cycle progression as shown in Fig. 1 and 2) could synergize with IR. MicroRNA-135b regulates ERα, AR and HIF1AN and affects breast and prostate cancer cell growth.

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.

Pancreatic cancer is a deadly cancer with a high unmet medical need.

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.

Background: AR-V7 status is considered a predictive biomarker for non-response to next generation androgen deprivation therapy (ADT) such as abiraterone and enzalutamide.

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. AR promotes prostate cancer survival and proliferation in prostate cancer cells [Balk, 2002; Feldman and Feldman, 2001].

AR-V7 is an androgen receptor splice variant that can be detected in circulating tumor cells of metastatic prostate cancer patients and is predictive of resistance to some drugs.

doi: 10.1016/j.clgc.2019.09.015. ARD-69 potently inhibits cell growth in these AR-positive prostate cancer cell lines and is >100 times more potent than AR antagonists. A single dose of ARD-69 effectively reduces the level of AR protein in xenograft tumor tissue in mice. We examined associations between AR-V7 status (positive vs. negative) and prostate-specific antigen (PSA) response rates (the primary end point), freedom from PSA progression (PSA progression AR-V7 is an androgen receptor splice variant that can be detected in circulating tumor cells of metastatic prostate cancer patients and is predictive of resistance to some drugs.
