(Submitter supplied) The overall goal of this study was to identify genes that were differentially-expressed in C4-2B MDVR cells treated with Indocin. C4-2B MDVR were either treated with Indocin (20 uM) or DMSO vehicle control for 3 days, followed by isolation of total cellular RNA. Transcriptome analysis was performed with RNA-Sequencing (RNA-Seq) in order to identify differentially-expressed genes (DEGs) induced by Indocin treatment.

(Submitter supplied) Background. Androgen receptor splice variant-7 (AR-V7) is a truncated form of the androgen receptor protein which lacks the ligand-binding domain, the target of enzalutamide and abiraterone, but remains constitutively active as a transcription factor. We hypothesized that detection of AR-V7 in circulating tumor cells (CTCs) from men with advanced prostate cancer would be associated with resistance to enzalutamide and abiraterone. more...

(Submitter supplied) Prostate cancer is the most commonly diagnosed and second-most lethal cancer among men in the United States. The vast majority of prostate cancer deaths are due to castration-resistant prostate cancer (CRPC) – the lethal form of the disease that has progressed despite therapies that interfere with activation of androgen receptor (AR) signaling. One emergent resistance mechanism to medical castration is synthesis of intratumoral androgens that activate the AR. more...

(Submitter supplied) Since its discovery, there has been one central issue of significant clinical relevance related to expression of the truncated androgen receptor splice variant-7 (AR-v7), which lacks the C-terminal ligand binding domain and thus acquires ligand-independent transcriptional activity in castration-resistant prostate cancer (CRPC). That question is whether AR-v7 is simply a marker of enhanced AR transcriptional activity characteristic of resistance to 2nd generation androgen receptor signaling inhibitors (ARSi) like Abiraterone and Enzalutamide, or whether it drives lethal resistance to ARSi. more...

(Submitter supplied) Constitutively active androgen receptor (AR) signaling confers resistance to AR-targeted therapies. Here we show that the ubiquitin-mediated proteolysis pathway plays a critical role in the degradation of AR and its variants, particularly variant 7 (AR-V7). AR/AR-V7 proteinhomeostasis (proteostasis) requires interaction of the E3 ubiquitin ligase STUB1 and HSP70complex. STUB1 disassociates AR/AR-V7 from HSP70, leading to AR/AR-V7 ubiquitination and degradation. more...

(Submitter supplied) Prostate cancer is the second leading cause of cancer death among men in the United States. The androgen receptor (AR) antagonist enzalutamide is a FDA-approved drug for treatment of patients with late-stage prostate cancer and is currently under clinical study for early-stage prostate cancer treatment. After a short positive response period to enzalutamide, tumors will develop drug resistance. In this study, we uncovered that DNA methylation was deregulated in enzalutamide-resistant cells. more...

(Submitter supplied) Androgen Receptor (AR) is a key player in prostate cancer development and progression. Here, we applied immunoprecipitation mass spectrometry of endogenous AR in LNCaP cells to identify individual components of the AR transcription complex. In total, 66 known and novel AR interactors were identified in the presence of R1881, which were critically and selectively required in AR-driven prostate cancer cell proliferation. more...

(Submitter supplied) RNA-sequencing data of the prostate cancer xenograft PC346C-DCC-K model. Tumor bearing mice were treated daily with Enzalutamide (N=10, 60mg/kg) or placebo (N=5, vehicle) for a period of 7 days. Tumor were subsequently isolated and snap-frozen. Tumor tissue was lysed and homogenized in QIAzol (ref #79306, Qiagen, Hilden, Germany) using an Ultra-Turrax T25 (Janke & Kunkel, Staufen, Germany). Total RNA was isolated using the miRNA-easy mini kit (ref # 217004, Qiagen), and RNA quality was measured using the Bioanalyzer RNA 6000 Nano assay (ref #5067, Agilent, Santa Clara, California, USA). more...

(Submitter supplied) Background: Most forms of castration-resistant prostate cancer (CRPC) are dependent on the androgen receptor (AR) for survival. While, enzalutamide provides a substantial survival benefit, it is not curative and many patients develop resistance to therapy. Although not yet fully understood, resistance can develop through a number of mechanisms, such as AR copy number gain, the generation of splice variants such as AR-V7 and mutations within the ligand binding domain (LBD) of the AR. more...

(Submitter supplied) Epidemiological and molecular evidence indicate that sphingolipids may play a role in the resistance of prostate cancer to androgen receptor signalling inhibitors such as enzalutamide, through the metabolism of ceramide into sphingosine-1-phosphate (S1P) which activates specific G-protein coupled receptors present on cancer cells and immune cells. Sphingosine kinase inhibitors which prevent the production of S1P have anti-cancer effects in vitro and in animal models. more...

(Submitter supplied) Enzalutamide (formerly MDV3100 and available commercially as Xtandi), a novel androgen receptor (AR) signaling inhibitor, blocks the growth of castration-resistant prostate cancer (CRPC) in cellular model systems and was shown in a clinical study to increase survival in patients with metastatic CRPC. Enzalutamide inhibits multiple steps of AR signaling: (1) binding of androgens to AR, (2) AR nuclear translocation, and (3) association of AR with DNA. more...
