Project description:The primary goal of this experiment was to determine the endogenous miRNA that are differentially expressed between prostate adenocarcinoma cells, DU-145 and prostate immortalized epithelial cells, PWR-1E. Subsequently, we performed other analysis with BLAST and in silico algorithm searches to determine the appropriate miRNA that could regulate a novel gene MIEN1.

Project description:MiRNAs are small non-coding RNAs that regulate the expression of specific mRNA targets mainly by translational repression, mRNA deadenylation or cleavage. This series is meant to identify miRNAs deregulated in prostate cancer (PCa) by comparing the PCa cell lines LNCaP, PC3 and Du-145 to the normal prostate epithelial cell line RWPE-1. We analyzed three arrays each for LNCaP, PC3, Du-145 and RWPE-1 cell lines

Project description:Withaferin A (WA), a major chemical component of an Indian herb Withania somnifera, induces cell death (apoptosis/necrosis) in a variety of tumor cells, but its molecular mechanism remains elusive. We report that WA induces cell death selectively in high-grade prostate (PC-3 and DU-145) and tongue (SAS) cancer cells but not in normal human fibroblast (TIG-1) and low-grade prostate cancer (LNCaP) cells. To identify genes whose expression levels were up- or down-regulated in prostate cancer cells following WA treatment, we examined the transcriptome profiles of mRNA prepared from TIG-1, LNCaP, PC-3 and DU-145 cells using Agilent’s Whole Human Genome Microarray.

Project description:Disseminated prostate cancer cells colonize the skeleton to progress into macroscopic lesions only if they successfully adapt to the bone microenvironment. We previously reported that the ability of prostate cancer cells to generate skeletal tumors in animal models correlated with the expression of the alpha-receptor for Platelet-Derived Growth Factor (PDGFRa). In this study we aimed to identify PDGFRa-regulated genes responsible for the acquisition of a bone-metastatic prostate phenotype. We performed genome-wide expression comparative analyses of human prostate cancer cell lines that differ for PDGFRa expression and propensity to establish tumors in the skeleton of animal models. We investigated the genes that were differentially regulated in the highly bone-metastatic PC3-ML cells and their low-metastatic counterpart PC3-N cells, and the genes differentially regulated between PC3-N and PC3-N with overexpression of PDGFRa (PC3NRa). We have previously shown that DU-145 cells lack PDGFRa and fail to survive longer than three days as disseminated tumor cells after homing to the mouse bone marrow. Interestingly, and in contrast to PC3-N cells, the exogenous expression of PDGFRa did not promote metastatic bone-tropism of DU-145 cells in our model. Thus, we examined the genes that were differentially regulated between DU-145 and DU-145(Ra) and excluded them from our candidate genes. Finally, to refine our findings and compensate for PC3 and DU-145 genetic disparity, we performed a comparative analysis of the genes differentially regulated between two bone metastatic single-cell progenies that were derived from PC3-ML cells.

Seven human prostate cancer cell lines were analyzed in total for this study. Each cell line was analyzed in duplicate from two different passages in culture.

Project description:Microarray-based DNA methylation and gene expression profiling was carried out using a panel of prostate cancer cell lines (LNCaP-FGC, DU-145, and PC-3) and the control normal prostate RWPE1 cell line. The identification of prostate cancer-specific methylation markers was based on the following criteria: a difference in DNA methylation level (β) of at least 0.5, and at least a 2-fold difference in expression level between cancer and control cells. Using highly stringent selection criteria, we identified novel hypermethylated genes whose expression was silenced in prostate cancer cells.
