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.
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

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:MDA-MB-435 breast cancer cells were treated with 2ME2 (2 µM) or vehicle alone. RNA was extracted and genomic profiling was performed using 22k Agilent microarrays. Keywords: Treatment-response

Project description:The project profiled the expression patterns in hypoxia induced secretomes between MDA-MB-231 parental and MDA-MB-231 Bone Tropic (BT) breast cancer cell lines which have been previously generated by Massague and colleagues (Kang et al. Cancer Cell 2003).
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:Human breast cancer cells MDA-MB-435 had higher metastatic potential and other aggressive characteristics than MCF-7 cells. Next-generation RNA sequencing (RNA-Seq) was used to clear this concern through comparison the transcriptomic expression profiles of these two cells.
Project description:In an effort to identify novel signaling molecules modulated by α-TEA, microarray analyses were performed. DNA array data obtained from human MDA-MB-435 breast cancer cells treated with 40 µM α-TEA for 12 h revealed over 400 genes that were consistently either up- or down-regulated. Thirty-four genes were selected based on their possible involvement in the known biological activities of α-TEA, and three: phorbol-12-myristate 13-acetate-induced protein (PMAPI) which codes for the protein NOXA, ABL2 which codes for the protein referred to as ARG (Abelson-related gene) and THBS1 which codes for thrombospondin 1, TSP-1 were chosen for further study. Keywords: Anti-cancer drug (aTEA at 40 uM 12 hour) treatment for MDA-MB-435 cells
