Transcription profiling of human PC3 cells transfected with androgen receptor treated with various concentration of androgens

ABSTRACT: We compared PC3 cells with or without harboring the wild-AR construct in the growth conditions of 1nM R1881, 10nM R1881 and ethanol (the solvent for R1881). The MOCK control is PC3 cells transfected with the empty vectors. Experiment Overall Design: 2 PC3 Samples transfected with empty vector, without R1881, 2 PC3 Samples transfected with AR, treated with Ethanol, 2 PC3 Samples transfected with AR, treated with 1nM R1881, 1 PC3 transfected with AR, treated with 10nM R1881.

Genome-wide profiling of H3K27ac, H3K4me1, H3K27me3 and H3K9me3 (ChIP-seq) in U2OS-GR and U2OS-AR cells

Project description:We performed ChIP-seq targeting the H3K27ac, H3K4me1, H3K27me3 and H3K9me3 in the U2OS-GR and U2OS-AR cell lines. The cell lines are derived from U2OS ATTC:HTB-96 and stably transfected with an expression construct for either rat GR or human AR, respectively. The U2OS-GR cells were treated with dexamethasone (1 µM) or vehicle (ethanol) for 90 minutes. The U2OS-AR cells were treated with R1881 (5 nM) or vehicle (DMSO) for 4 hours.

ChIP-seq of the androgen receptor (AR) in MDAMB453 cells after androgen stimulation

Project description:Serum starved MDAMB453 cells were serum starved and treated for 4 hours with vehicle control (ethanol), 5α-dihydrotestosterone (DHT; 10nM) or medroxyprogesterone acetate (MPA; 10nM). AR binidng peaks were determined. Subsequent analysis showed that binding sites for androgen receptor are enriched at breast cancer risk loci.

TALEN-Engineered AR Gene Rearrangements Reveal Endocrine Uncoupling of Androgen Receptor in Prostate Cancer

Project description:This experiment addressed the question of whether full length Androgen receptor and Androgen Receptor variant ARv567es have similar transciptional activities. The transcriptomes of R1-AD1, a AR full length expressing cell line, are compared in an AR on (1nM DHT) to an AR off (ethanol vehicle) state. R1-D567 was derived from R1-AD1 and modified with TALENs in such a way as to express only AR-V567es. The AR on and off states were induced with a control siRNA (AR on) or a siRNA targeting exon 1 (AR off). R-AD1 was cultured for 24 hours in either base RPMI media with 1nM DHT or ethanol vehichle and RNA extracted. R1-D567 cells were electroporated with control siRNA or siRNA targeting exon 1 of AR and allowed to recover 48 hours and then cultured in base media with 1nM DHT or ethanol for 24 hrs. Each conditon was done in triplicate.

The role of the transcription factors GATA2 and FOXA1 in immortalized basal-like prostate epithelial cells

Project description:GATA2 and FOXA1 are pioneering factors for Androgen Receptor (AR) in prostate cancer cells. Less is known about their role in benign epithelial prostate cells. We investigated if they had the ability to induce differentiation in an undifferentiated prostatic context. Benign basal-like prostate epithelial cells 957E/hTERT-AR cells (a gift from John T. Isaacs lab, Johns Hopkins, MD, USA) were transduced with LentiORF RFP control lentiviral particles. The 957E/hTERT-AR-RFP cells were then transduced with GATA2 and FOXA1 lentiviral particles, and we called the new cell lines hTERT/AR-GATA2 and hTERT/AR-FOXA1, respectively. hTERT/AR-GATA2 is a stable selected cell line and treated with 1 nM anabolic steroids, R1881, or ethanol (ET-OH) for 48 hrs. 957E/hTERT/AR-FOXA1 is a transient cell line, because FOXA1 protein is quickly lost. Twenty four hours post transduction with FOXA1 lentivral particles, 1 nM androgen R1881 or ethanol (ET-OH) were added at time for medium exchange and further treated for 24 hours. GATA-2 and FOXA1 ability to induce differentiation was assessed.

Androgen receptor splice variants mediate enzalutamide resistance in castration-resistant prostate cancer cell lines

Project description:The goal of this experiment was to compare the gene expression programs mediated by androgen/AR vs. constitutively active, truncated AR variants in castration-resistant CWR-R1 prostate cancer cells. Because constitutive activity of truncated AR variants can mask androgen/AR target genes, the androgen/AR transcriptional program was assessed by silencing the trucnated AR 1/2/3/CE3 variant with siRNA targeting AR exon CE3 and treating cells with vehicle (ethanol) or 1nM DHT. Similarly, because full-length AR activity can mask truncated AR variant target genes, the AR variant transcriptional program was assessed under castrate conditions by selectively silencing full-length AR with siRNA targeting AR exon 7, and comparing this profile with CWR-R1 cells transfected wtih siRNA targeting AR exon 1, which silences all AR expression (full-length and truncated AR variants). CWR-R1 cells were maintained under castrate conditions in long term culture in order to enrich for the population of cells harboring a 48kb intragenic deletion in AR intron 1. These late-passage CWR-R1 cells were electroporated with siRNAs targeting AR exon 1, AR exon 7, or AR exon CE3. Electroporated cells were seeded in RPMI 1640 medium containing antibiotics and 5% charcoal-stripped, steroid-depleted medium and allowed to recover for 48h. After this 48h recovery, electroporated cells were switched to serum-free RPMI 1640 with 1nM DHT or 0.1% ethanol (vehicle control) for an additional 24h prior to extraction of total RNA. Three independent biological replicates were performed.

Gene expression of LNCaP cells grown in 2D cultures and polyethlene glycol-based hydrogels with the presence of synthetic androgen, R1881

Project description:Analysis of LNCaP cell molecular differences and their response to R1881 in 2D and 3D cultures. Androgen regulated genes were differentially expressed between 2D and 3D cultures. These results provide insights into factors that influence the expression of androgen regulated genes In this study, LNCaP cells cultured in tissue culture plastic (2D) and in the hydrogel (3D) were maintained up to 3 days and 24 days respectively in serum containing media before they were androgen-starved for 48 hours. Cells were either treated with 1nM R1881 or continued to be androgen-deprived (without R1881 with 0.008% ethanol) for another 48 hours prior to cell harvest for gene expression analysis. Biological triplicates were prepared for each condition.

Genome-wide expression profiling of Hic-5 knockdown in PshTert-AR human myofibroblasts

Project description:Identifying the effect of the co-regulator Hic-5 (TGFB1I1) on global androgen receptor transcriptional activity in PShTert-AR prostate fibroblast cells with view to further elucidating the broader biological role of Hic-5 on fibroblast spceific androgen signaling. Knockdown of Hic5 for 48 hours in PShTert-AR cells significantly altered the androgen regulation of approximately 1347 genes. The effect of Hic-5 knockdown was to suppress androgen regulation of approximately 85% of those transcripts, by either reducing androgen mediated repression or activition of gene expression. PShTert-AR cells were transfected with 10nM non-specific control siRNA (NS) or with commercially avaliable Hic-5 specific siRNA (siHic5) for 24hrs. Cells were kept in 5% hormone stripped FBS RPMI for a further 24 hours and subsequently treated with either ethanol vehicle control or 10nM DHT for 16hr. Total RNA was extracted. Nine independent vehicle and 9 DHT siNS and siHic5 samples were pooled into three groups of vechicle and DHT treated siNS and siHic5 samples and hybrydised to Affymetrix Human Gene 1.0 ST array chips.
