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 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.

Mutation of this methylation site on AR results in a transcriptionally hyperactive AR, suggesting that the proliferative effects of Prostate cancer (PC) is the most commonly diagnosed nonskin malignancy and the second most common cause of cancer death among men in the United States. Epigenetics is the study of heritable changes in gene expression caused by mechanisms other than changes in the underlying DNA sequences. Two common epigenetic mechanisms, DNA methylation and histone modification, have … 2016-07-15 2014-01-31 PPAR ligands regulate AR signaling within human prostate cancer cells. In AR-positive castration-sensitive prostate cancers such as LNCaP and VCaP cells (a), PPAR agonists and the PPAR antagonist GW9662 have been shown to decrease AR transcriptional activity. Agonist-induced reductions in AR signaling appear to occur independently of PPAR, while it is currently not known if PPAR is required 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.

Androgen receptor (AR) positive vs negative roles in prostate cancer cell deaths including apoptosis, anoikis, entosis, necrosis and autophagic cell death Androgen/androgen receptor (AR) signaling plays pivotal roles in the prostate development and homeostasis as well as in the progression of prostate cancer (PCa). Androgen receptor (AR) is a steroid receptor transcriptional factor for testosterone and dihydrotestosterone consisting of four main domains, the N-terminal domain, DNA-binding domain, hinge region, and ligand-binding domain. AR plays pivotal roles in prostate cancer, especially castration-resistant prostate cancer (CRPC). Prostate Adenocarcinoma + AR is altered in 15.92% of prostate adenocarcinoma patients [ 4 ]. AR Positive is an inclusion criterion in 1 clinical trial for prostate adenocarcinoma, of which 0 are open and 1 is closed. Androgen Receptor Splice Variant, AR-V7, as a Biomarker of Resistance to Androgen Axis-Targeted Therapies in Advanced Prostate Cancer Clin Genitourin Cancer . 2020 Feb;18(1):1-10.

2017-10-27 · AR-V7-positive prostate cancer should be considered a novel prostate cancer subtype that should be distinguished upon initial biopsy. The main limitation of this study is its observational nature.

2017-10-10 2019-05-16 2014-09-03 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. 2014-04-08 AR (androgen receptor) is a gene that encodes the androgen receptor protein.

Herein, we report a case that presented with a retroperitoneal cancer of unknown primary that was confirmed as an androgen receptor‐positive adenocarcinoma without prostate‐specific antigen elevation. 3.1 Enzalutamide‐resistant prostate cancer cells express higher levels of AR‐V7. The role of AR‐V7 in the mechanism of resistance to ENZ was first tested in two different ENZ‐resistant prostate cancer cell lines, VCaP‐ENZR and C4‐2B ENZR. 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 Prostate cancer is in its latest stages when it has spread to nearby locations such as bones, lymph nodes, and organs. While survival rates for all stages before this are extremely high, once prostate cancer has metastasized to other parts of the body, the survival rates over the next five years are below 30 percent, according to the ACS. 2014-01-08 · CDK11p58 promoted the prostate cancer cell apoptosis and inhibited its metastasis in a kinase dependent way. And finally CDK11p58 could inhibit the metastasis of AR positive prostate cancer cells through inhibition of integrin β3 and MMP2.

[abstract]. Abstract. Androgen receptor (AR) gene aberrations are rare in prostate cancer before primary hormone treatment but emerge with castration resistance.To determine AR gene status using a minimally invasive assay that could have broad clinical utility, we developed a targeted next-generation sequencing approach amenable to plasma DNA, covering all AR coding bases and genomic regions that are Androgen deprivation followed by acute androgen stimulation selectively sensitizes AR-positive prostate cancer cells to ionizing radiation February 11, 2016 The current standard of care for patients with locally advanced prostate cancer is a combination of androgen deprivation and radiation therapy. We initially focused our experiments on the AR-positive prostate cancer cell line LNCaP because the majority of research on IL6-mediated AR activity has been performed with those cells.

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.
