Profiling of RWPE cells stably over-expressing ETV1

Project description:RWPE benign prostatic epithelial cells were infected with a lentivirus expressing ETV1 or GUS (control), and stable clones were isolated by puromycin selection. ETV1 over-expression, recapitulating ETS gene rearrangements observed in vivo, confers invasiveness in the benign prostate cell line RWPE. Keywords: genetic modification Four hybridizations in total were performed using RWPE cells stably expressing ETV1 or GUS (control) on Agilent Whole Human Genome Oligonucleotide Microarrays. RWPE-ETV1 (Cy5) / RWPE-GUS (Cy3) and a dye flip were performed in duplicate

Expression profiling of human prostate non-tumorigenic RWPE-1 cells after overexpressing ERG and ETV1, and ERG and ETV1 silencing on prostate cancer cells LNCaP and VCaP, respectively

Project description:Chromosomal rearrangements involving ETS factors, ERG and ETV1, occur frequently in prostate cancer. We here examine human prostate non-tumorigenic RWPE-1 cells with ERG- or ETV1-expressing stable RWPE-1 cell. RWPE-1 stable cell clones overexpressing ERG and ETV1 were grown under normal conditions. 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.

Gene expression changes upon knockdown or over-expression of the ETS gene ETV4 in prostate cancer cell lines

Project description:Chromosomal abnormalities that give rise to elevated expression levels of the ETS genes ETV1, ETV4, ETV5, or ERG are prevalent in prostate cancer, but the function of these transcription factors in carcinogenesis is not clear. Previous work implicates ERG, ETV1, and ETV5 as regulators of invasive growth but not transformation in cell lines. Here we show that the PC3 prostate cancer cell line provides a model system to study the over-expression of ETV4. Anchorage independent growth assays and microarray analysis indicate that high ETV4 expression is critical for the transformation phenotype of PC3 cells. However, genes up-regulated upon ETV4 over-expression were very similar to genes up-regulated by ETV1 over-expression in the RWPE-1 normal prostate cell line. Together these data indicate that the ETV4 dependent transformation phenotype observed in PC3 cells is due to the genetic background of the cell line, rather than a distinct characteristic of ETV4. Furthermore, these findings suggest that the function of ETS genes in prostate cancer may differ based on other genetic alterations in a tumor. Two sets of two color experiments. First is PC3 cells expressing one of two independent ETV4 shRNAs versus PC3 cells expressing a control shRNA (luciferase). Second is RWPE-1 cells expressing 3xFlag tagged ETV4 versus RWPE-1 cells with a control (empty) vector.
