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
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.
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.
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.
Project description:Transcriptional profiling of LNCaP prostasphere-forming cells, comparing control untreated sphere-forming cells with hormone treated sphere-forming cells. Both estrogen (estradiol) and androgen (R1881) promote the sphere formation of human prostate cancer cell LNCaP. Goal was to determine the effects of hormones on global gene expression of LNCaP sphere-forming cells.

Both estrogen (estradiol) and androgen (R1881) promote the sphere formation of human prostate cancer cell LNCaP. Goal was to determine the effects of hormones on global gene expression of LNCaP sphere-forming cells. Five samples were analyzed. Control (ethanol 1hr), estradiol 1 hour, estradiol 24 hour, R1881 1 hour, R1881 24 hour.
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.
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.
Project description:LNCaP prostate cancer cells were infected by lentivirus expressing either ctrl or HOTAIR, and the cells were cultured in hormone-deprived condition (Ethl) or in the presence of androgen (R1881). C4-2B prostate cancer cells were infected by lentivirus expressing either shCtrl or shHOTAIR, and the cells were cultured in hormone-deprived condition (Ethl) or in the presence of androgen (R1881).
