(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) The majority of breast cancer subtypes express androgen receptor (AR) in addition to estrogen receptor α (ERα). Depending on the breast cancer subtype androgen signaling has either stimulatory or inhibitory roles in breast cancer cell growth. We have mapped AR cistrome in ERα negative human molecular apocrine breast cancer MDA-MB453 cells and analyzed it in relation to the androgen-regulated transcriptome in the same cells. more...

(Submitter supplied) Crosstalk of androgen signaling induced with dihydrotestosterone (DHT) and proinflammatory signaling induced with tumor necrosis-factor alpha (TNFa) was analyzed in prostate cancer cells (LNCaP) by following chromatin binding of androgen receptor (AR), p65 (activating subunit of nuclear-factor kappa-B [NFkB]), FOXA1 and PIAS1+2 chromatin binding using ChIP-seq and transcriptional changes using GRO-seq.

(Submitter supplied) We report the androgen receptor recruitment to the chromatin of androgen responsive prostate cancer cell lines, LNCaP-1F5 and VCaP in response to physiological androgen 5a-dihydrotestosterone (DHT) using ChIP-sequencing. We compare the AR recruitment by DHT to that by partial agonist/antagonist cyproterone acetate (CPA), mifepristone (RU486) and bicalutamide (Bica) in LNCaP-1F5 cells. We also report the role of glucocorticoid receptor recruitment in presence of dexamethasone (Dex) in androgen responsive prostate cancer cells. more...

(Submitter supplied) Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare AR binding activity in LNCaP cells with and without knockdown of GATA2. Methods: LNCaP cells between passage number 32-34 were used for assay. Cells are transfected with GATA2 specific or nonspecific siRNA and ChIP was performed, the ChIP producted was further used to generate library with illumina ChIP-seq kit. more...

(Submitter supplied) Androgen receptor (AR) is typically overexpressed in castration-resistant prostate cancer (CRPC). CRPC-derived VCaP cells display an excessive number of chromatin AR-binding sites (ARBs). This study analyzed direct transcription programs of the AR, the prevalence of AR enhancers and the transcriptional regulators involved in the regulation of at the enhancer regions. The analysis utilized global nuclear run-on sequencing (GRO-seq). more...

(Submitter supplied) FoxA1 has been shown critical for prostate development and prostate-specific gene expression regulation. In addition to its well-established role as an AR pioneering factor,several studies have recently revealed significant AR binding events in prostate cancer cells with FoxA1 knockdown. Furthermore, the role of FoxA1 itself in prostate cancer has not been carefully examined. Thus, it is important to understand the role of FoxA1 in prostate cancer and how it interacts with AR signaling.

(Submitter supplied) Androgen receptor (AR) plays an important regulatory role during prostate cancer development. AR’s transcriptional activity is regulated by androgenic ligands, but also by post-translational modifications. To study the role of the AR SUMOylation in genuine chromatin environment, we compared androgen-regulated gene expression and AR chromatin occupancy in PC-3 prostate cancer and HEK293 cell lines stably expressing wild-type (wt) or SUMOylation site-mutated AR (AR-K386R,K520R). more...
