Project description:Signaling through the vitamin D receptor (VDR) has been proposed to suppress the development of epithelial cancers, including prostate cancer. We conducted ChIP-seq to identify the VDR binding sites in the genome of the prostate epithelial cell line, RWPE1. This analysis reveals a large number of VDR binding sites in both control cells and in cells treated with 10 nM 1,25 dihydroxyvitamin D3 for 3 hours. These peaks are associated with genes controlling a wide variety of cellular functions.

Project description:The NKX3.1 homeobox gene functions in mitochondria to regulate oxidative stress To investigate the role of NKX3.1 in regulation of oxidative stress, we employed transcriptome analysis of mouse prostate ( from 4 month old Nkx3.1+/+ and Nkx3.1-/- mice treated with paraquat), and human prostate cells ( RWPE1 cells engineered with empty vector (altered pTRIPZ), NKX3.1 wild type over-expression, and NKX3.1 (R52C) over-expression treated with paraquat). Mouse tissue or human cells were snap frozen for subsequent molecular analysis.

Project description:We investigated the genomic activity of vitamin D in primary prostate epithelial cells (PrE) through vitamin D receptor (VDR)-ChIP-sequencing. PrE cells treated with 50 nM 1,25D showed nuclear localization the VDR within 1 hr, persisting until 4 hr, and a 2 hr treatment was selected for ChIP-seq. Rigorous testing of the ChIP conditions and VDR antibody were performed. Nearly 5,000 VDR binding sites were identified.

Project description:Background: Prostate cancer is the second leading cause of cancer mortality among US men. Epidemiological evidence suggests that high vitamin D status protects men from prostate cancer and the active form of vitamin D, 1α,25 dihydroxyvitamin D3 (1,25(OH)2D) has anti-cancer effects in cultured prostate cells. Still, the molecular mechanisms and the gene targets for vitamin D-mediated prostate cancer prevention are unknown. Results: We examined the effect of 1,25(OH)2D (+/- 100 nM, 6, 24, 48 h) on the transcript profile of proliferating RWPE1 cells, an immortalized, non-tumorigenic prostate epithelial cell line that is growth arrested by 1,25(OH)2D (Affymetrix U133 Plus 2.0, n=4/treatment per time and dose). Our analysis revealed many transcript level changes at a 5% false detection rate: 6 h, 1571 (61% up), 24 h, 1816 (60 % up), 48 h, 3566 (38 % up). 288 transcripts were regulated similarly at all time points (182 up, 80 down) and many of the promoters for these transcripts contained putative vitamin D response elements. Functional analysis by pathway or Gene Set Analysis revealed early suppression of WNT, Notch, NF-kB, and IGF1 signaling. Transcripts related to inflammation were suppressed at 6 h (e.g. IL-1 pathway) and suppression of proinflammatory pathways continued at later time points (e.g. IL-17 and IL-6 pathways). There was also evidence for induction of anti-angiogenic pathways and induction of transcripts for protection from oxidative stress or maintenance of cell redox homeostasis at 6 h. Conclusions: Our data reveal of large number of potential new, direct vitamin D target genes relevant to prostate cancer prevention. In addition, our data suggests that rather than having a single strong regulatory effect, vitamin D orchestrates a pattern of changes within prostate epithelial cells that limit or slow carcinogenesis. Experiment Overall Design: RWPE1 cells were treated with medium containing 100 nM of 1,25(OH)2D or vehicle (0.1% ethanol) for 6, 24 or 48 hours (n=4 per treatment, 24 total samples). The transcripts levels in each sample were measured by using the Affymetrix HU133 plus 2.0 GeneChip (Affymetrix, Santa Clara, CA).

Project description:Analysis of transcriptional changes during Myc or PI3K induced oncogenic transformation in RWPE1 cells (benign prostate epithelial cell line). The aim of the present study was to identify key epigenetic gene silencing events that occur during the oncogenic transformation events, hence emphasis was placed on downregulated genes. Results provide important information on which are the tumor suppressive pathways or genes that will be epigenetically silenced by during Myc or PI3K induced oncogenic transformation. Total RNA obtained from oncogenic transformed RWPE1 cells which were either overexpressing Myc or constitutive active mutant of PI3K (E545K) as compared to RWPE1 cells expressing the empty vector control PMN.

Project description:Analysis of acute effects of ligand-treatment on vitamin D receptor binding genome-wide using ChIP-seq. THP-1 monocytic leucemia cells were treated with 1?,25(OH)2D3 (1,25D) or left unstimulated to investigate the acute effects of VDR chromatin occupancy. We identified in total 2340 VDR binding sites with and without the ligand. Without the ligand, there is a considerable presence of VDR already on the chromatin. However, upon a short (40 min) ligand treatment VDR shifts from sites that rarely contain a DR3 type element to sites that frequently contain one or more DR3-type element. Genome-wide identification of VDR binding in THP-1 cells at the unstimulated state and after 40 min ligand (10 nM 1?,25(OH)2D3 (1,25D, calcitriol)) treatment.

Project description:Precise gene regulation is needed for the correct differentiation and function of cells. This is especially important when putting cells through stimuli that would change their characteristics. To understand the changes in chromatin accessibility of prostate cells when stimulating them with testosterone, we performed the ATAC-seq (Assay for Transposase Accessible Chromatin using sequencing). We have worked with the normal epithelial prostate cell line RWPE1, an heterogenous cell line composed of two subpopulations: WPE-stem (stem cell phenotype) and WPE-int (intermediate cellular subtype) and treated it with DHT. Our aim was to study haemoglobin gene regulation in prostate cells, and check whether changes in cell stimulus would lead to changes in chromatin accessibility in both haemoglobin loci. Nevertheless, the results obtained could be used to compare chromatin accessibility between DHT treated and untreated cells on any loci.
