(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) The development of resistance to current standard-of-care treatments, such as androgen receptor (AR) targeting therapies, remains a major challenge in the management of advanced prostate cancer. There is an urgent need for new therapeutic strategies targeting key resistant drivers such as AR variants like AR-V7 and steroidogenic enzymes such as AKR1C3 to overcome drug resistance and improve outcomes for patients with advanced prostate cancer. more...

(Submitter supplied) Prostate cancer C4-2B cells were cultured in enzalutamide in a dose-escalation manner. After sixty passages cells were resistant to enzalutamide, with a specific sets of genes been deregulated. We performed global gene expression analysis by cDNA microarrays to identify genes responsible for enzalutamide resistance in C4-2B-MDVR cells.

(Submitter supplied) The purpose of this study was to characterize the downstream transcriptomic effects of ARVib-mediated degradation of AR/AR-V7, particularly in attenuating AR/AR-V7 target gene expression in prostate cancer cells. Towards this goal, next-generation sequencing (NGS)-based gene expression profiling (RNA-Sequencing; RNA-Seq) was performed on castration-resistant prostate cancer (CRPC) C4-2B MDVR cells that were treated with vehicle control or one of the AR/AR-V7 inhibitors (ARVib), ARVib-7 or ARVib-31.

(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...

MED12 and cyclin-dependent kinase 8 (CDK8) or its paralog CDK19 are components of its kinase module that regulate the proliferation of prostate cancer cells. In this study, we investigated how MED12 and CDK8/19 influence cancer-driven processes in prostate cancer cell lines, focusing on AR activity and enzalutamide resistance.

(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) Continued androgen receptor (AR) signaling is an established mechanism underlying castration-resistant prostate cancer (CRPC), and suppression of AR signaling remains a therapeutic goal of CRPC therapy. Constitutively active androgen receptor splicing variants (AR-Vs) lack the AR ligand-binding domain (AR-LBD), the intended target of androgen deprivation therapies (ADT) including new CRPC therapies such as abiraterone and MDV3100. 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) 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...
