Gene expression profile of LNCaP prostate cancer cells with exogenous HNF4G expression

Project description:To determine genes regulated by HNF4G, we retrovirally infected LNCaP cells in triplicates to express HNF4G and empty vector as control. cDNA for HNF4G in pDONR201 vector was obtained from Harvard medical school Plasmid database (ID:HsCD00022314) and was cloned into an murine stem cell virus (MSCV)-based retroviral vector with puromycin selection marker (Addgene) using Gateway technology.

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.

Effect of hyper-and hypoactivation of Notch signaling in IL-4-stimulate THP-1

Project description:MSCV-GFP-IRES (IRES), MSCV-GFP-Myc-NIC1 (NIC1) and MSCV-GFP-DNMAML (DNMAML) were retrovirally transduced in to THP-1 cell (pCL-Ampho was used as packaging plasmid). GFP positive cells were sorted for selective desired cell. Then IRES, NIC1 and DNMAML overexpressing THP-1 were pretreated with PMA (5ng/ml) for 48 h before stimulation with IL-4 (20 ng/ml) for 3 h.

shRNA-mediated knockdown of ETV4 and MED25 in the prostate cell line PC3 reveals set of genes potentially coregulated by MED25 and ETV4

Project description:Our in vitro binding studies support a model whereby MED25 exhibits multivalent interactions with a subset of related ETS factors, ETV1/4/5. We hypothesize that the interaction would allow for coregulation of genes by ETV1/4/5 and MED25, acting perhaps to link the ETVs to the Mediator complex. To explore this possibility, we compared the genome occupancy for FLAG-tagged MED25 and ETV4 in the prostate cancer cell line PC3, which overexpresses ETV4. We also tested for relevance of MED25 and ETV4 binding to for gene expression in PC3s. We found a high degree of overlap in the FLAG-MED25 and ETV4 ChIPs datasets consistent with our model, and also identified a subset of target genes co-dependent on Med25 and ETV4.

Aberrant stabilized ETV4 expression cooperates with loss of p53 to promote invasive prostate carcinoma

Project description:Chromosomal translocations or upregulations involving ETS transcription factor are frequent events in prostate cancer pathogenesis and significantly co-occurrence with p53 or PTEN loss. Caused by the low stabilities of ETS proteins in cytosol, mouse models with aberrant expression of wild type ETS transcription factors had subtle phenotypes and only drive prostate cancer progression in the setting of Pten loss. Here we show that prostate specific aberrant expression of mutated ETV4 (V70P71D72-AAA, ETV4-AAA), which is resistence to COP1 mediated protein degradation, results in more stabilized ETV4 protein in mouse prostate. We found that ETV4-AAA mice develop marked prostatic intraepithelial neoplasia (mPin) and p53-dependent cell senescence within 2 weeks, but without tumor development when aged. Interestingly, ETV4-AAA positive cells reduce dramatically in a PTEN loss background, which means that there is no cooperation between ETV4-AAA and PTEN loss. Aberrant ETV4-AAA expression promotes progression of mPin to prostatic adenocarcinoma in a Tp53 deficiency or haploinsufficiency background. In contrast to PTEN loss induced mouse prostate cancers which loss NKX3.1 expression and resistant to castration therapy, these ETV4-AAA tumor cells well maintain AR and NKX3.1 expression and are sensitive to castration therapy.

Expression profile of HNF1A knockdown and overexpression in 22RV1 and LNCaP cells respectively

Project description:To determine genes regulated by HNF1A in 22Rv1, we performed siRNA mediated knockdown of HNF1A using pooled siHNF1A (L-008215-00-0005 5 nmol) and pooled siSCR purchased from Dharmacon. RNA was harvested 3 days after transfection and gene expression profiling was performed. Similarly to determine genes regulated by HNF1A in LNCaP, we performed retroviral transduction of LNCaP cells in duplicate for HNF1A and empty vector control expression. cDNA for HNF1A in RC211201 vector (origene) was subcloned into a murine stem cell virus (MSCV)-based retroviral vector with hygromycin selection marker (Addgene). After 3 days of transduction, cells were selected for four days in hygromycin and later on RNA was harvested for gene expression profiling.

Murine ES Cells: Control vs. ETV4/5 double KO

Project description:ETS-related transcription factors ETV4 and ETV5 play crucial roles for organogenesis and morphogenesis. We compared the transcriptional profiles between wild-type and ETV4 and ETV5 double knockout (ETV4/5 dKO) ES cells by an oligo DNA microarray analysis. Self-renewal capacity and pluripotency are known to be controlled by an ES cell-specific transcription factor network; therefore, we focused on transcription-associated genes. Of 1258 transcription-related genes, 47 genes were significantly downregulated and 98 genes were significantly upregulated in ETV4/5 dKO ES cells. Several genes whose expression is specific to undifferentiated ES were repressed in ETV4/5 dKO ES cells. In contrast, expression of differentiation markers was enhanced in ETV4/5 dKO ES cells.
