Genes regulated by HS3ST2

ABSTRACT: We used Affymetrix HG U133 Plus 2.0 GeneChips to compare the transcriptome of HS3ST2-transfected and control vector-transfected MDA-MB-231 cells. MDA-MB-231 cells were transfected with HS3ST2- or control-vector. Subsequently, total RNA was collected and processed for analysis using Affymetrix microarrays. Three independent replicates were prepared for each comparison group.

Heparan sulfate 3-O-sulfotransferase 2 (HS3ST2), an enzyme mediating 3-O-sulfation of heparan sulfate (HS), is silenced by hypermethylation in breast cancer. As HS has an important co-receptor function for numerous signal transduction pathways, the phenotypical changes due to HS3ST2 reexpression were investigated in vitro using high and low invasive breast cancer cell lines. Compared to controls, highly invasive HS3ST2-expressing MDA-MB-231 cells showed enhanced Matrigel invasiveness, transendot ...[more]

Genes regulated by miR-145

Project description:We used Affymetrix HG U133 Plus 2.0 GeneChips to compare the transcriptome of miR-145-overexpressing MDA-MB-231 cells against negative control miRNA precursor-transfected cells. MDA-MB-231 cells were transfected with pre-miR-145 or a negative control pre-miRNA, and subsequently total RNA was collected and processed for analysis using Affymetrix microarrays. Three independent replicates were prepared for each comparison group.

miRNAs were significantly regulated by myocardin and ERM-NM-1

Project description:Using microarray, we compared miRNAs expression profiles of MDA-MB-231 cells transfected with myocardin and empty vector (pcDNA3.1) and found that 25 miRNAs were significantly changed in myocardin-transfected groups (17 up-regulated and 9 down-regulated miRNAs). Moreover, we showed that 18 of 25 miRNAs significantly regulated by myocardin were inhibited by ERM-NM-1 in MDA-MB-231 cells. In addition,through a microarray approach, we identify the subset of miRNAs modulated by ERM-NM-1 in MDA-MB-231 cells. Our results determined that ERM-NM-1 may function as tumor-promoter through down-regulating expression of 3 miRNAs (miR-26b, miR-146a and miR-331-3p) in MDA-MB-231 cells. There are 4 samples in this experiment (pcDNA3.1-transfected, myocardin-transfected, ERM-NM-1-transfected, myocardin plus ERM-NM-1 co-transfecteded groups) and each sample was replicated 3 times. The vector-pcDNA3.1 was used as control.

Transcription profiling of human MDA-MB-231 breast cancer cells in vitro and in vivo as xenografts to assess the effect of ectopic expression of sFRP1

Project description:RNA was isolated from ectopically sFRP1-expressing MDA-MB-231 cells and control MDA-MB-231 cells and as well from tumor lysates arising from these cells as nude mouse xenograft. Gene expression profiles for these samples were investigated using Affymetrix arrays. Experiment Overall Design: MDA-MB-231 human breast cancer cells were stably transfected with human sFRP1 encoding vector or empty vector as control. After the selection with antibiotics, three clones of MDA-MB-231/sFRP1 and three clones of MDA-MB-231/control were selected. These six clones were cultured individually in DMEM 10% FCS with 1mg/ml G-418. When cells reached 70-80% confluence, RNA was isolated from the cells. In parallel, the three clones of MDA-MB-231/sFRP1 and the three clones of MDA-MB-231/control were pooled respectively. One million of cells from each pool were suspended in 100ul PBS and injected to fat pads of female balb/c nude mice (6 mice were injected with MDA-MB-231/sFRP1 and 5 mice were injected with MDA-MB-231/control) to do a xenograft experiment. A few - several weeks after, mice were sacrificed when tumor reached a certain size, tumors were taken and RNA was isolated using trizol reagent.

The miRNA profiling in MDA-MB-231, MDA-MB-231/E1A and knockdown of Dicer in MDA-MB-231/E1A cells

Project description:Dicer, RNase III endonuclease, is an essential enzyme in miRNA biogenesis that regulates target gene expression, and it has been reported that aberrant expressions of Dicer associate with the clinical outcomes of patients in various cancers. To explore the miRNA differencial expression regulated by Dicer in MDA-MB-231/E1A cells, the microarray profiling analysis was employed to conduct differentially expressed miRNAs in stable MDA-MB-231/vector, MDA-MB-231/E1A, and MDA-MB-231/E1A/shDicer cells.
