Project description:Transcriptional regulator REST plays a key role in repressing neuronal specific genes in prostate cancer and other non-neuronal tissues. Moreover, loss of REST is observed in neuroendocrine prostate tumors. Here, we use ChIP-seq analysis to study genome–wide REST occupied regions in the prostate cancer cell line, LNCaP. REST occupied regions were then correlated to gene expression changes occurring between prostate adenocarcinoma and neuroendocrine prostate tumors in vivo.

Project description:To identify genomic regions which display concordant gene expression in prostate cancer, we performed expression profiling of normal prostate epithelial cells (PrEC) and the prostate cancer cell line LNCaP. These expression arrays were integrated ChIP-on-chip studies of active and repressive epigenetic marks in same cells to discover and characterise regions of Long Range Epigenetic Silencing (LRES) in prostate cancer.

Project description:To identify genomic regions which display concordant epigenetics alterations in prostate cancer, we performed MeDIP and ChIP-on-chip profiling of normal prostate epithelial cells (PrEC) and the prostate cancer cell line LNCaP. These promoter arrays were integrated with expression arrays of the same cells to discover and characterise regions of Long Range Epigenetic Silencing (LRES) in prostate cancer.

Project description:BACKGROUND. Human prostate cancer LNCaP and PC-3 cell lines have been extensively used as prostate cancer cell models to study prostate cancer progression and to develop therapeutic agents. Although LNCaP and PC-3 cells are generally assumed to represent early and late stages of prostate cancer development, respectively, there is limited information regarding comprehensive gene expression patterns between these two cells lines and relating these cells to prostate cancer progression based on their gene expression. METHODS. Comprehensive gene expression analysis was performed in LNCaP and PC-3 cells. Total RNA was isolated from cultured cells and hybridized to Illumina human Ref-8 version 3 BeadChips representing 24,526 transcripts. Bioinformatics approach was applied to identify genes, their functional roles and interaction networks that are unique in either LNCaP or PC-3 cells. RESULTS. We observed large differences in gene expression between LNCaP and PC-3 cells.Using robust statistical analysis and very high significance criteria to identify tractable number of genes 115 and 188 genes were identified uniquely expressed in LNCaP and PC-3 cells, respectively. Genes uniquely expressed in LNCaP cells contained UDP-glucosyltransferases as a signature for this cell line. This cell line demonstrated upregulation of various metabolic pathways on gene expression level. Talα/β, GATA-1 and c-Myc/Max were identified by in silico analysis as possible transcription factors regulating unique LNCaP genes. PC-3 cells were characterized by cytosceleton-related genes, keratins in particular. Several other well known genes (VEGFC, IL8, TGFβ2 and others) scattered throughout literature were identified and summarized in the discussion. CONCLUSIONS. This study demonstrated that LNCaP and PC-3 cells represent two distinct prostate cancer cell lineages. LNCaP cells retain many prostate cell specific properties, whereas PC-3 cells have acquired more aggressive bone-like characteristics following bone metastasis and show little resemblance to prostate cells. Microarray studies confirmed previously published results and provided more information between these two prostate cancer cell lines. Future studies need to consider their similarities and differences in gene expression between localized and metastasized prostate cancer.

Project description:Understanding the systemic regulation of normal prostate gene expression by cholesterol diet is critical for deciphering the mechanisms responsible for the transition from healthy to pathogenic prostate conditions. To understand mechanism under cholesterol effect on prostate, we performed microarray analysis using LNCaP human prostate cells cultured in low cholesterol medium. The RNA is obtained from LNCaP human prostate cells serum-starved for 0h, 3h, 16h followed by CLM medium.
