Analysis of RWPE1 cells, an immortalized, non-tumorigenic prostate epithelial cell line, treated with 1,25(OH)2D (i.e., the active form of vitamin D), for up to 48 hrs. RWPE1 cells are growth arrested by 1,25(OH)2D. Results provide insight into the role of vitamin D in prostate cancer prevention.

(Submitter supplied) 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. more...

Comparisons between each treatment groups provide evidence for the crosstalk between VDR and AR mediated signaling events at the transcriptional levels, which may have significant clinical impact in patient care.

(Submitter supplied) 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. more...

(Submitter supplied) High grade prostate intraepithelial neoplasia (HGPIN) is a precursor lesion for prostate cancer. The APT121 mouse is a model of early stage prostate cancer that develops PIN lesions that progress to adenocarcinoma over a period of 6 months. At 12 wks of age APT121 mouse prostate contains mostly high grade PIN lesions. We compared the transcript profile of RNA from the anterior prostate of age- and genetic background matched wild type and APT121 mice using Affymetric microarrays.

(Submitter supplied) A major goal in prostate stem cell biology is to identify genes, pathways, or networks that control self-renewal and multilineage differentiation. We hypothesize that 1,25 dihydroxyvitamin D3 can induce differentiation of prostatic progenitor/stem cells, thus serving as an in vitro model with which to study the molecular mechanisms of stem cell differentiation by 1,25 dihydroxyvitamin D3. 1,25 dihydroxyvitamin D3 elicits its effects primarily through transcriptional regulation of genes, so microarray studies were used to gain insight into the cellular response to 1,25 dihydroxyvitamin D3. more...

(Submitter supplied) d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxicity) in brain tissue. The transcriptomic changes that occur in the brain after d-serine exposure have not been fully explored. more...

(Submitter supplied) Inflammatory signals must be regulated and kept in check in order to prevent tissue damage.  This is especially true in the cornea, where damage can induce loss of transparency, essential for vision.  Toll-like receptors (TLRs) are present at the ocular surface and, in addition to being protective against infection, have also been implicated in the pathogenesis of dry eye syndrome, an inflammatory condition that affects millions of individuals in the United States each year.   Therefore, an important area of research is the development of new anti-inflammatory therapeutics that limit aberrant ocular surface inflammation.  Vitamin D has been studied for its role in suppressing inflammation in other tissues.  In previous studies, we have demonstrated that vitamin D is able to decrease proinflammatory mediators induced by TLRs in human corneal epithelial cells (HCEC).  Therefore, the goal of the current study was to examine this mechanism further through an evaluation of vitamin D’s influence on gene expression in two different HCEC cell lines. more...

(Submitter supplied) Open chromatin regions have been shown to associate with the location of transcriptiotal enhancers, i.e., the binding locations of DNA-binding transcription factors. To investigate the effects of short-term treatment by the nuclear hormone 1α,25-dihydroxyvitamin D3 (VD), a specific ligand of the transcription factor vitamin D receptor, on chromatin accessibility, FAIRE-seq was utilized on the chromatin samples from THP-1 monocytic leukemia cells that were treated with 100 nM 1α,25-dihydroxyvitamin D3 for 20, 40, 60, 80, 100 and 120 min, or with vehicle (0.1% (v/v) ethanol) for 20 and 100 min.

(Submitter supplied) Cancer cells differentiate along specific lineages that largely determine their clinical and biologic behavior. Distinct cancer phenotypes from different cells and organs likely result from unique gene expression repertoires established during lineage commitment in the embryo and maintained after malignant transformation. We used comprehensive gene expression analysis to examine this concept in the prostate, an organ with a readily manipulable developmental program and a high propensity for cancer. more...

(Submitter supplied) 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.
