(Submitter supplied) Androgen receptor (AR) is a ligand-dependent transcription factor that plays a key role in the onset and progression of prostate cancer. We investigated AR-induced gene expression in prostate cancer cells LNCaP and abl by transfecting siAR / siControl or treating cells with androgen (DHT) over a time course. Keywords: siRNA transfection and androgen stimulation time course

(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) 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) Androgen receptor (AR) orchestrates an intricate transcriptional regulatory network that governs prostate cancer initiation, development and progression. To understand this network in detail, we generated genome-wide maps of AR occupancy by ChIP-seq in LNCaP cells. We found NKX3-1, an androgen-dependent homeobox protein well-characterized for its role in prostate development and differentiation, being recruited to AR binding sites (ARBS) in response to androgen signaling. more...

(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) 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) 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) Prostate cancer is the most common cancer in men and AR downstream signalings promote prostate cancer cell proliferation. We identified RUNX1 is an androgen-regulated gene. In order to investigate the RUNX1 function in prostate cancer cells, we performed gene expression in AR-positive prostate cancer cell lines after siRUNX1 treatment. We also treated cells with vehicle or androgen to analyzed the effects of RUNX1 on AR function.
