(Submitter supplied) We report the application of ChIP and RNA sequencing to identify the mechanism whereby stable overexpression of MED19 in androgen-dependent LNCaP cells promotes growth under conditions of androgen deprivation. We determined the MED19 and AR transcriptomes and cistromes in control and MED19 LNCaP cells. We also examined genome-wide H3K27 acetylation in both the absence and presence of androgens. We found that MED19 overexpression selectively alters AR occupancy, H3K27 acetylation, and gene expression. more...

(Submitter supplied) We report the application of RNA sequencing to uncover the process through which sustained overexpression of the canonical MED19 isoform in androgen-dependent LNCaP cells enhances growth under conditions of androgen deprivation. We identified the canonical MED19 transcriptome by comparing control LNCaP cells with those expressing canonical MED19. This research offers significant understanding of the mechanism by which prostate cancer cells grow under low androgen conditions, emphasizing the key role of the canonical MED19 isoform in this process.

(Submitter supplied) The androgen receptor (AR) is a mediator of both androgen-dependent and castration- resistant prostate cancers. Identification of cellular factors affecting AR transcriptional activity could in principle yield new targets that reduce AR activity and combat prostate cancer, yet a comprehensive analysis of the genes required for AR-dependent transcriptional activity has not been determined. Using an unbiased genetic approach that takes advantage of the evolutionary conservation of AR signaling, we have conducted a genome-wide RNAi screen in Drosophila cells for genes required for AR transcriptional activity and applied the results to human prostate cancer cells. more...

(Submitter supplied) The androgen receptor (AR) directs diverse biological processes through interaction with coregulators such as androgen receptor trapped clone-27 (ART-27). The impact of ART-27 on genome-wide transcription was examined. The studies indicate that loss of ART-27 enhances expression of many androgen-regulated genes, suggesting that ART-27 inhibits gene expression. Surprisingly, classes of genes that are upregulated upon ART-27 depletion include regulators of DNA damage checkpoint and cell cycle progression, suggesting that ART-27 functions to keep expression levels of these genes low. more...

(Submitter supplied) The androgen receptor (AR) plays a key role in progression to incurable androgen-ablation resistant prostate cancer (PCA). We have identified three novel AR splice variants lacking the ligand binding domain (designated as AR3, AR4 and AR5) in hormone insensitive PCA cells. AR3, one of the major splice variants expressed in human prostate tissues, is constitutively active and its transcriptional activity is not regulated by androgens or antiandrogens. more...

(Submitter supplied) The androgen receptor (AR) antagonist darolutamide has very recently been approved for the treatment of non-metastatic castration resistant prostate cancer (PCa). Here we determined the genome-wide effects of darolutamide on cis-acting regulatory elements involved in androgen signaling with a focus on enhancer and super-enhancer (SE) regions. Darolutamide strongly depleted the AR from regulatory elements and abolished the AR transcriptional signaling. more...

Analysis of late passage (LP50) LNCaP cells treated with AR shRNA or control shRNA, grown in hormone-free media to deplete androgen, and treated with androgen R1881 or vehicle. Results provide insight into molecular mechanisms underlying acquired androgen independence of late passage LNCaP cells.

(Submitter supplied) Prostaste cancer (PC) is the most commonly diagnosed male malignancy and an important cause of mortality. Androgen signaling plays a key role in PC pathogenesis and the understanding of the mechanisms involved in the regulation of AR function might pave the ground for the development of more efficacious and long-lasting therapeutic strategies for PC patients. DNA/RNA helicases are emerging as important regulators of many cellular processes. more...

(Submitter supplied) Long intergenic non-coding RNA (lincRNA) PVT1 is an oncogene known to be overexpressed in various types of cancer. PVT1 high expression is associated with increased prostate cancer (PCa) risk while androgen-independent PCa progression is correlated with increased androgen receptor (AR) expression. However, the mechanism of PVT1 and AR involvement in the development of prostate cancer is still unclear. more...
