(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) We report the dual role of FoxA1 in androgen receptor recruitment to the chromatin of androgen responsive prostate cancer cell line LNCaP-1F5 using ChIP-sequencing. Depletion of FoxA1 reprograms both androgen and glucocorticoid receptor recruitment and subsequent gene expression. The ChIP-seq has been performed using AR, FoxA1, GR, H3K4me2 antibodies. We have also mapped the DNaseI-hypersensitive sites (DHS) using deep sequencing.

(Submitter supplied) AR is tightly regulated by many transcriptional cofactors, including key pioneer factor such as FOXA1 and GATA2. While FOXA1 was recently shown to be able to redistribute AR across the genome, how GATA2 regulates AR cistrome has not been carefully investigated. Here, we report that, unlike FOXA1, GATA2 is unable to reprogram AR, but instead it enhances AR program by inducing AR expression and augmenting AR co-occupancy, thereby acting as a pure AR coactivator, rather than a pioneer factor. 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...

(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) signaling is a key driver of prostate cancer (PCa) growth and progression. Understanding the factors influencing AR-mediated transcription provides new opportunities for therapeutic intervention. We have previously discovered that a genetic variant in one of the DNA repair genes, PARP2, is associated with aggressive PCa. Here, we show that a high expression level of PARP2 in PCa tumors is associated with high Gleason scores and biochemical recurrence using The Cancer Genome Atlas (TCGA) dataset. more...
