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.
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:NQO1 silencing by a specific shRNA against NQO1 increased migration and hormone-independent survival in hormone-dependent human prostate cancer cells LNCaP. Genome wide array revealed that NQO1 blockade significantly upregulated pro-inflammatory mediators (e.g., IL-32, CCL2, IL-8, IL-17C, IL-10RA, CXCR2, CXCR7, NOS3) associated with prostate tumorigenesis. Two-condition experiment, control vs. NQO1 knockdown LNCaP cells. Biological replicates: 3 control replicates, 3 NQO1 knockdown replicates.
Project description:Chromosomal rearrangements involving ETS factors, ERG and ETV1, occur frequently in prostate cancer. We here examine human prostate cancer cells control VCaP and LNCaP cells with ERG- or ETV1-silenced VCaP or LNCaP cells, respectively, in hormone deprived and stimulated conditions.
Project description:Transcriptional profiling of human prostate cancer cell line LNCaP treated with Metformin or AICAR compared to control non-stimulated LNCaP.
Project description:Methylation profiling of human prostate cancer tissues and cell lines. We mapped the global DNA methylation patterns in prostate tissues (n=17) and cells (n=2) from fifty nanograms of genomic DNA using Methylplex-Next Generation Sequencing (M-NGS). In addition, genes methylated in LNCaP and significantly overexpressed after 5’Azacytidine treatment of LNCaP cells are assessed by Agilent gene expression microarray. The comprehensive methylome map presented here will further our understanding of epigenetic regulation of the prostate cancer genome. [Gene expression] Two-condition experiment, control DMSO-treated vs. 5'aza-treated LNCaP at two time points (@24 and 48 hours) in replicates.
Project description:Comparison of miRNA expression profiles directly comparing PC3 cells to LNCaP cells using unamplified and amplified miRNA. Keywords: Expression profiling of hormone sensitive vs. insensitive prostate cancer cell lines and evaluation of amplification fidelity
Project description:Chromosomal rearrangements involving ETS factors, ERG and ETV1, occur frequently in prostate cancer. We here examine human prostate cancer cells control VCaP and LNCaP cells with ERG- or ETV1-silenced VCaP or LNCaP cells, respectively, in hormone deprived and stimulated conditions. VCAP and LNCaP cells, 24 hr after ERG or ETV1 RNA interference, respectively, were grown in hormone-depleted conditions for 2 days, and then in the presence of EtOH (vehicle) or 10nM DHT for 16hr. Total RNA was extracted from three biological replicates. This was used to hybridize to Affymetrix expression arrays using the HG-U133 Plus 2.0 platform.
Project description:Genome-wide DNA methylation profiling of human PC3 invasive prostate cancer cell line treated with vehicle control (SAH, S-adenosylhomocysteine) and with SAM (S-adenosylmethionine) as well as of untreated human LNCaP non-invasive prostate cancer cell line. The Illumina Infinium 450k Human DNA Methylation BeadChip v1.2 was used to obtain DNA methylation profiles across approximately 450,000 CpGs in human cell lines exposed to described treatments. Samples included biological triplicate of PC3 control (SAH treated), biological triplicate of PC3 treated with SAM, and biological duplicate of LNCaP untreated.
