Project description:Prostate cancer is the most common cancer in men and androgen receptor (AR) downstream signalings promote prostate cancer cell proliferation. To investigate the AR signaling, we performed directional RNA sequence analysis in AR positive prostate cancer cell line, LNCaP and VCaP. Using Noncode and GENCODE data sets. We identified androgen-regulated long non-coding RNAs (lncRNAs) in prostate cancer cells. Directional RNA sequence analysis of androgen-regulated lncRNAs in prostate cancer cells

Project description:Androgen receptor (AR) is a master transcription factor that drives prostate cancer (PCa) development and progression. Alterations in the expression or activity of AR coregulators significantly impact the disease's outcome. To identify all the essential components of the AR coregulator complex, we utilized a proteomic approach called rapid immunoprecipitation of endogenous proteins (RIME) to systematically identify all coregulator proteins of the AR interactome in PCa cells.

Project description:The goal of this analysis is to profile AR-regulated genes, especially non-coding RNAs in three androgen sensitive prostate cancer cell lines, MDA-PCA-2B, LNCaP and VCaP. The two cell lines were serum-starved first, followed by dihydrotestosterone (DHT) stimulation or treated with Enzalutamide (AR inhibitor) without starvation. Transcriptome profiling was generated by RNA-sequencing from polyA-selected RNA. These experiments are followed by knock-down experiments of AR and ARlnc1 in MDA-PCA-2B, and also Enzalutamide (anti-androgen) treatment of LNCaP cells.

Project description:We profiled androgen receptor (AR) genomic targets using high-throughput sequencing of chromatin-immunoprecipitated (ChIP) DNA from TMPRSS2-ERG fusion gene positive DUCaP prostate cancer cells. ChIp-seq and microarray gene expression profiling datasets were integrated with the NHGRI GWAS PCa risk SNPs catalog to identify disease susceptibility SNPs localized within functional androgen receptor binding sites (ARBSs). Eighty GWAS index or linked SNPs were found to be localized in ARBSs. Among these rs11891426:T>G in the 7th intron of the melanophilin gene was found located within a novel putative auxiliary AR binding motif, which we found enriched in the neighborhood of canonical androgen responsive elements. T→G exchange attenuated the transcriptional activity of the ARBS in an AR reporter gene assay of prostate cancer cell models. It went also in line with decreased melanophilin protein level in primary prostate tumors with G allele.These results unravel a hidden link between androgen receptor and a functional PCa risk SNP, whose allele alteration affects androgen regulation of its host gene melanophilin . Genomic profile of androgen receptor binding sites of androgen or vehicle treated DUCaP cells using ChIP-seq. IgG precipiated DNAs from both treatments served as controls.

Project description:Prostate epithelial cells depend on androgens for survival and function. In early prostate cancer, besides survival, androgens also regulated tumor growth, which is exploited by androgen ablation/ blockade therapies in metastatic disease. The aim of the present study was to characterize the role of the androgen receptor pathway in prostate cancer progression and to identify potential disease markers. Microarray analysis was used to establish the androgen-regulated gene expression profile, upon stimulation with the synthetic androgen R1881 or the antiandrogen hydroxyflutamide, of the androgen-responsive PC346C cell line and its derivative castration-resistant sublines: PC346DCC (vestigial AR levels), PC346Flu1 (AR overexpression) and PC346Flu2 (T877A mutated AR)

Each condition was performed in dye-swap, using biological duplicates. PC346DCC was only stimulated with R1881, not hydroxyflutamide.
