Transcriptome profiles of alternative MED19 LNCaP and control LNCaP cells cultured under androgen deprivation with vehicle or R1881

Project description:We report the application of ChIP and RNA sequencing to identify the mechanism whereby stable overexpression of MED19 in androgen-dependent LNCaP cells promotes growth under conditions of androgen deprivation. We determined the MED19 and AR transcriptomes and cistromes in control and MED19 LNCaP cells. We also examined genome-wide H3K27 acetylation in both the absence and presence of androgens. We found that MED19 overexpression selectively alters AR occupancy, H3K27 acetylation, and gene expression. Under conditions of androgen deprivation, genes regulated by MED19 correspond to genes regulated by ELK1, a transcription factor that binds the AR N-terminus to induce select AR target gene expression and proliferation. This study provides important insight into the mechanisms of prostate cancer cell growth under low androgen, and underscores the importance of the MED19 in this process.

Transcriptome profiles of canonical MED19 LNCaP and control LNCaP cells cultured under androgen deprivation with vehicle or R1881 treatment

Project description:We report the application of RNA sequencing to uncover the process through which sustained overexpression of the canonical MED19 isoform in androgen-dependent LNCaP cells enhances growth under conditions of androgen deprivation. We identified the canonical MED19 transcriptome by comparing control LNCaP cells with those expressing canonical MED19. This research offers significant understanding of the mechanism by which prostate cancer cells grow under low androgen conditions, emphasizing the key role of the canonical MED19 isoform in this process.

Chromatin immunoprecipitation of human LNCaP cells treated with synthetic androgen R1881 or ethanol (vehicle) using androgen receptor antibody

Project description:LNCaP cells were grown in charcoal stripped media for 48hrs and then treated for 1hr with the synthetic androgen R1881 or ethanol (vehicle). Cell extracts from both treatment conditions were then subjected to chromatin-immunoprecipitation using an anti-androgen receptor antibody, before labeling and hybridisation to a microarray containing 24,000 gene promoter regions.

Expression data from androgen treated LNCaP cells

Project description:Androgens are required for the development of normal prostate, and they are also linked to the development of prostate cancer. We used microarrays to understand the role of androgen in an androgen dependent, androgen receptor (AR) positive human metastatic cell line, LNCaP. LNCaP cells were grown in RPMI medium and they were subjected to stay in phenol-red free, RPMI with charcoal stripped serum for 48h. Synthetic androgen R1881 was added and the cells were allowed to grow for 48h. Control cells were given with corresponding amount of ethanol as vehicle which is used for the solubilization of R1881. Cells were harvested and RNA was isolated for microarray analysis.

Androgen arrays for Resveratrol-Induced Gene Expression Profiles in Human Prostate Cancer

Project description:Arrays for Expression levels of androgen-responsive genes in LNCaP cells exposed to dihydrotestosterone, R1881. Gene-expression changes in LNCaP treated with 1 nmol/L R1881 at 7, 9, 18, 24, 50, and 72 hours; 10 nmol/L dihydrotestosterone at 18 and 50 hours; 100 nmol/L dihydrotestosterone and 1 5mol/L dihydrotestosterone at 24 hours; and androgen deprivation at 46 and 70 hours. This set corresponds to Figure 2 of the publication. An all pairs experiment design type is where all labeled extracts are compared to every other labeled extract. Keywords: all_pairs

Identification of direct androgen-target genes in the prostate cancer cell line LNCaP

Project description:Transcriptional profiling of the LNCaP cell line treated with R1881 synthetic androgen and/or cycloheximide. LNCaP cells were stimulated with R1881 alone, with cycloheximide alone, or with R1881 in the presence of cycloheximide for 24h and compared to control untreated cells. Two independent cell culture experiments for each treatment condition were performed for microarray analysis. Each experiment was repeated with a switch in fluorescent Cy3/Cy5 labels to account for dye effects to produce four data points per hybridization spot.

Fine mapping of androgen regulated genes in LNCaP cells

Project description:Detailed analysis of androgen regulated gene expression in the LNCaP prostate cancer cell line. Since androgens and the AR are known to be important for prostate cancer cell proliferation and invasion we aimed to identify androgen receptor (AR) regulated genes by combining this detailed Illumina beadarray study of androgen regulated gene expression with AR ChIP-sequencing data. LNCaP cells were grown in RPMI medium supplemented with 10% charcoal dextran stripped (steroid depleted) FBS for 72h, before treatment with 1nM R1881 or vehicle control. Total RNA was harvested every 30min for 4h and then every hour up to 24h using trizol (Sigma), quantified using a Nanodrop spectrophotometer (ND-1000). RNA samples were prepared for analysis on Illumina Human 6 v2 BeadArrays and Biotrove Realtime PCR panels according to the manufacturers protocols (see Supplementary Methods for details). Expression array data were normalised in R using the beadarray software and BASH (see Supplementary Methods for details) (Cairns et al., 2008; Dunning et al., 2007).
