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. The four groups including vector control, E1A-expressing and Dicer knockdown in E1A-expressing MDA-MB-231 cells were harvested and RNA were isolated. Two independent experiments were performed for each group.

Project description:To determine gene expression changes in vasculogenic mimicry competent human breast cancer cells with loss of FOXC2 we performed RNA-seq of MDA-MB-231 cells with FOXC2 knockdown.
Project description:Identification of MUC4-associated expression of genes by comparing MUC4 knockdown (MDA-MB-231-shMUC4) and control (MDA-MB-231-SCR).
Project description:CD44, an adhesion molecule that binds to extracellular matrix, primarily to hyaluronan (HA), has been implicated in cancer cell migration, invasion, and metastasis. CD44 has also recently been recognized as a marker for stem cells of several types of cancer. However, the roles of CD44 in the development of bone metastasis still remain unclear. To explore this issue, we established the MDA-MB-231 human breast cancer cells stably expressing short hairpin RNA against CD44. The CD44-knockdown MDA-MB-231 cells (MDA-MB-231 shCD44-2 and shCD44-3) were analyzed. As control, MDA-MB-231 cells stably expressing shRNA against firefly luciferase (shLuc) were used. Total of three samples. No replicates.
Project description:To investigate the differential expression of genes in human tumor xenografts of control MDA-MB-231 primary tumors (Ctrl) and srGAP1 knockdown MDA-MB-231 primary tumors.
Project description:Identification of genes that are involved in self-seeding by comparing gene expression profiles between parental MDA-MB-231 cells and seeder cells (MDA-231-S1a and S1b) 2 replicates from each sample (parental MDA-MB-231, MDA-MB-231 S1a and MDA-MB-231 S1b) were analyzed
Project description:Identification of MUC4-associated expression of genes by comparing MUC4 knockdown (MDA-MB-231-shMUC4) and control (MDA-MB-231-SCR). Two-condition experiment, MUC4 knockdown cells vs. control. Biological replicates: 2 control, 2 sh-MUC4 transfected, independently grown and harvested. one replicate per array.
