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.

Long-term androgen withdrawal and treatment (R1881) of LNCaP-FGC prostate cancer cells

Project description:LNCaP cells were cultures in steroid depleted medium for 5 days before treatment with synthetic androgen (R1881, 10nM) for 16h. Transcriptomics analysis was performed to compare gene expression changes induced by androgen withdrawal or androgen treatment. Genome-wide transcriptomic analysis of LNCaP cells grown in steroid depleted medium, normal (steroid-containing) medium and R1881 treated cells was performed using the Agilent platform

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.

RNA-sequencing of LNCaP prostate cancer cells with and without treatment of enzalutamide

Project description:LNCaP prostate cancer cells were stimulated with the synthetic androgen R1881. RNA-sequencing was performed to identify changes induced by enzalutamide treatment on the transcriptome level.

Prostate cancer cell line LNCaP treated for 2, 4, 6, 8 h with the synthetic androgen R1881 (1nM)

Project description:Time series of the prostate cancer cell line LNCaP, treated for 2, 4, 6 and 8 hours with the synthetic androgen R1881. As control, the cells were cultured for 2, 4, 6 and 8 hours in the presence of the same concentration of solvent (ethanol). With this short treatment time, we aimed to identify mainly direct targets of the androgen receptor. LNCaP has a very low growth rate in steroid stripped medium and resumes growth on addition of androgens. Keywords: Time course

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.

Androgen repsonsive microRNAs in LNCaP cell Lines

Project description:The goals of this study were to evaluate changes in microRNA expression following androgen treatment. Four treatment groups were studied: untreated and those treated with 0.1, 1.0, and 10.0 nM of synthetic androgen (R1881). Data is relative to the untreated sample.

Genome-wide RNA-sequencing (RNA-seq) of benign and malignant prostate cell lines without and with androgen (R1881) stimulation.

Project description:RNA-seq data were obtained from hTERT immortalized human prostate transit amplifying EP156T cells (+/- 10 nM R1881 for 48 hrs), progeny tumorigenic EPT3-M1 cells recovered from mouse metastatic tumor (+/- 10 nM R1881 for 48 hrs) and the prostate cancer cell lines LNCaP (+/- 10 nM R1881 for 48 hrs), VCaP (+/- 1 nM R1881 for 24 hrs) and 22Rv1 (+/- 1 nM R1881 for 24 hrs) (obtained from the American Type Culture Collection). All cells were either stimulated or not stimulated with the synthetic androgen R1881 (1 or 10 nM for 24 or 48 hrs) prior to lysis (Qiagen miRNeasy minikit lysis buffer) and total RNA purification and DNase treatment.

Contribution of WDR77 and p53 to androgen response in prostate cancer cells

Project description:To decipher the contribution of WDR77 and p53 to androgen-responsive gene expression, effect of siRNA-mediated silencing of WDR77 and p53 on expression of androgen-dependent genes was studied. Human LNCaP prostate cancer cells were transfected with individual siRNA SmartPools targeting WDR77 or p53 or a non-targeting siRNA SmartPool. Forty-two hours after transfection, cells were treated with synthetic androgen R1881 (5nM) or vehicle. Three biological replicates were generated per treatment group. Forty-eight hours later, total RNA was isolated and processed for Illumina oligoarray analysis.
