Project description:The androgen receptor is considered as the key promoter of prostate cancer. It is a transcription factor that controls the transcription of hundreds of its target genes. In this project we focuses on how androgen receptor stimulation by the synthetic androgen R1881 can affect the proteome of peroxiosmes and the antioxidant enzymes in LNCaP 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.
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: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
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).
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. Five samples were analyzed. Control (ethanol 1hr), estradiol 1 hour, estradiol 24 hour, R1881 1 hour, R1881 24 hour.
Project description:We generated and characterized an androgen-independent LNCaP-AI cell line by long-term culture of androgen-dependent LNCaP cells in RPMI-1640 medium containing charcoal-stripped serum. This approach used to generate the line mimics the castration resistant condition for treating prostate cancer, supporting the relevance of the LNCAP-AI cell line to Castration Resistant Prostate Cancer.
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.
