(Submitter supplied) We report the high-throughput profiling of histone modification and DNase I hypersensitivity sites in prostate cancer and breaset cancer cells. We found that while AR binding is associated with nucleosome depletion, ER binding is not. We showed that a quantitative measure of DNase I hypersensitivity changes is a powerful tool in indentifying transcription factor cistromes.

(Submitter supplied) Estrogen Receptor (ESR1) drives growth in the majority of human breast cancers by binding to regulatory elements and inducing transcription events that promote tumor growth. Differences in enhancer occupancy by ESR1, contribute to the diverse expression profiles and clinical outcome observed in breast cancer patients. GATA3 is an ESR1 co-operating transcription factor mutated in breast tumors, however its genomic properties are not fully defined. 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) 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) 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) Using DNase-seq, mRNA-seq and publicly available ChIP-seq data sets, we examined the role of chromatin accessibility (DNase-seq) in androgen receptor binding to the genome (ChIP-seq) and AR-mediated transcriptional changes (mRNA-seq). Our data reveals genome-wide changes in chromatin structure that correspond to AR binding and differential gene expression. A focused examination of DNase-seq data around androgen receptor motifs within androgen receptor ChIP-seq peaks reveals distinct patterns of protection from DNaseI cleavage.

DNA was then recovered, and single-end Illumina sequencing libraries were prepared using the Crawford DNase-seq method (Song and Crawford, 2010).
