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

ABSTRACT: 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.

Expression data from LNCaP cells treated with DHT and enzalutamide

Project description:Enzalutamide (formerly MDV3100 and available commercially as Xtandi), a novel androgen receptor (AR) signaling inhibitor, blocks the growth of castration-resistant prostate cancer (CRPC) in cellular model systems and was shown in a clinical study to increase survival in patients with metastatic CRPC. Enzalutamide inhibits multiple steps of AR signaling: (1) binding of androgens to AR, (2) AR nuclear translocation, and (3) association of AR with DNA. Here we used Affymetrix human genome microarray technology to investigate the global programme of gene expression of LNCaP cells in response to enzalutamide alone and in the context of DHT-stimulated androgen receptor gene expression. LNCaP cells were grown in RPMI 1640 supplemented with 5% hormone depleted FBS and treated with vehicle (control sample) , DHT (100 nM), enzalutamide (1 or 10 M-BM-5M) or DHT (100 nM) plus enzalutamide (1 or 10 M-BM-5M)for 16 hours for RNA extraction and hybridization. Each condition was done in triplicate.

RNA sequencing of LNCaP cells treated with castration and/or enzalutamide

Project description:The goal of this study was to determine how androgen receptor inhibition alters transcriptional programs in prostate cancer cells. LNCaP prostate cancer cells were grown in 10% charcoal-stripped serum (CSS) supplemented with 0.5 nanomolar dihydrotestosterone (DHT), in CSS without DHT modeling castration, with CSS + DHT but in the presence of 10 micromolar enzalutamide, or in CSS without DHT (castrated) and in the presence of enzalutamide for 72 hours. Analysis shows that androgen receptor target genes are reduced with castration, enzalutamide or the combination of castration + enzalutamide.

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.

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

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

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.

Enzalutamide resistance in prostate cancer cells

Project description:Castration resistant prostate cancer (CRPC) develops resistance to antiandrogens affecting Androgen Receptor (AR) signaling through a variety of mechanism. Because of this, the efficacy of androgen receptor targeted therapy remains limited for many patients with CRPC. We developed LNCaP-enzalutamide (ENZU) and resistance cells to study changes in transcriptomic profile compared to parental cells.
