Project description:Knock-down of LSD1 using siRNA approach induced regulation of several proliferation-associated genes in ER-negative breast cancer cells MDA-MB-231. To identify changes on gene expression caused by treatment with siRNA directed against LSD1 (si) or control siRNA (control) in MDA-MB-231 cells, total RNA was purified from the cells after treatment for 6 days (2 rounds of transfection). Three biological replicates were used.

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.
Project description:We cultured the ER negative breast cancer cell line MDA-MB-231 and the ER positive breast cancer cell line MCF7 in serine-free media for 24h. RNA was extracted from the cells and submitted for RNA sequencing.
Project description:To examine the role of NONO in estrogen-independent breast cancer, MDA-MB-231 cells were treated with siRNA targeting NONO or control siRNA (siControl). Microarray analysis revealed NONO-regulated genes in MDA-MB-231 cells.
Project description:The high-throughput sequencing technology was performed after the treatment of human triple negative breast cancer cells MDA-MB-231 and BT549 with Lespedeza bicolor root extracted by ourselves, to explore the expression of genes related to cell proliferation, adhesion, migration and invasion of human triple negative breast cancer cells MDA-MB-231 and BT549 after the treatment of Lespedeza bicolor root changes, and to find an interesting target gene.
Project description:MDA-MB-231 are a metastatic triple-negative breast cancer cell line that bears a missense p53 mutation (R280K). We depleted endogenous mutp53 in MDA-MB-231 cells by siRNA transfection, and treated the cells with Tumor Necrosis Factor (TNF)-alpha. Microarray analysis was performed to evaluate the impact of mutant p53 on the transcriptional response triggered by TNFα in these cells. MDA-MB-231 cells transfected with control or p53 siRNA were treated with TNFα for 20 hrs or left untreated. The study comprises four experimental points, each in triplicate.
