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:We used RNA sequencing to analyze gene expression profiles of MDA-MB-231 and its brain metastasis variant (231-BR). The goal of this study is to explore genes that are differentially expressed in 231-BR and MDA-MB-231.
Project description:To determine the differentially expressed miRNAs in MDA-MB-231-GATA3 cells vs. MDA-MB-231-Control cells Pooled polyclonal cells from MDA-MB-231 breast cancer cells +/- GATA3 over-expression were analyzed for miRNA expression
Project description:To investigate the function of Neuropilin-1 (NRP-1) in breast cancer MDA-MB-231 cells. CRISPR-Cas9 gene editing was used to knockout (KO) the NRP-1 gene in MDA-MB-231 human triple-negative breast cancer cells. Differentially expressed genes (DEGs) were determined in NRP-1 KO and parental MDA-MB-231 cells using whole transcriptome next-generation sequencing.
Project description:RNA-Sequencing of basal subtype triple negative breast cancer cells, MDA-MB-231. MDA-MB-231 cells were lentivirally transduced with pLKO short-hairpin (sh) luciferase control or shZnf148 in triplicates. Differentially expressed genes by the shRNA compared to the control were determined.
Project description:RNA-Seq profiling of MCF-7 and MDA-MB-231. We profiled RNA expression in the estrogen-receptor-positive (ER+) MCF-7 and the triple-negative MDA-MB-231 breast cancer cells. The objective was to find genes differentially expressed between these cell lines as potential drivers of invasiveness of the triple-negative MDA-MB-231. We further utilized the identified differential genes to validate expression-responsive module of non-canonical Wnt signaling pathway.

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:Proteomic analysis of differentially expressed proteins in MDA-MB-231 and MCF-10A cell lines when miR-200c and miR-203 were transiently expressed or inhibited, respectively.
