(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) Although the vital role of the androgen receptor (AR) has been well demonstrated in primary prostate cancers, its role in the androgen-insensitive prostate cancers still remains unclear. Here, we used a small hairpin RNA approach to directly assess AR activity in prostate cancer cells. Reduction of AR expression in the two androgen-sensitive prostate cancer cell lines, LNCaP and LAPC4, significantly decreased AR-mediated transcription and cell growth. more...

(Submitter supplied) Androgen receptor (AR) is a ligand-dependent transcription factor that plays a key role in the onset and progression of prostate cancer. Surprisingly little is known of AR binding sites and collaborating transcription factors in the human genome. Here we have identified the DNA sequence motifs that are significantly enriched within the authentic 90 AR target regions found on chromosomes 21 and 22 in human prostate cancer cells by combining chromatin immunoprecipitation for AR with chromosome-scale tiled oligonucleotide microarrays. more...

(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) To study the importance of PIAS1 (protein inhibitor of activated STAT1) for the androgen-regulated transcriptome of VCaP prostate cancer cells, we silenced its expression by RNAi. Transcriptome analyses revealed that a subset of the androgen-regulated genes is significantly influenced, either activated or repressed, by PIAS1 depletion. The depletion also exposed a completely new set of genes to androgen regulation, suggesting that PIAS1 can mask genes from androgen receptor (AR). more...

(Submitter supplied) Expression levels of retinoic acid receptor gamma (NR1B3/RARG, encodes RARG), are commonly reduced in prostate cancer (PCa). Therefore we sought to establish the cellular and gene regulatory consequences of reduced RARG expression, and determine RARG regulatory mechanisms. RARG shRNA approaches in non-malignant (RWPE-1 and HPr1-AR) and malignant (LNCaP) prostate models revealed that reducing RARG levels, rather than adding exogenous retinoid ligand, had the greatest impact on prostate cell viability and gene expression. 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...
