Project description:To characterize the effect of Core regulatory element (CRE) deletion in breast cancer cell line (MDA-MB-231 cells), we performed gene expression RNA-seq analysis for WT and KO (Core Regulatory Element deleted) MDA-MB-231 cells after 0h, 6h and 24h of P/I treatment.
Project description:Aurora Kinase B and ZAK interaction model
Equivalent of the stochastic model used in "Network pharmacology model predicts combined Aurora B and ZAK inhibition in MDA-MB-231 breast cancer cells" by Tang et. al. 2018.
The only difference is cell division and partitioning of the components, which are available in the original model for SGNS2.
Project description:Data-independent acquisition (DIA) mass spectrometry was used to study the effect of JAG1 protein in ECM organization in breast cancer. TNBC cell line samples including MDA-MB-231 cells (Jag1WT), JAG1 knock-out of MDA-MB-231 cells (Jag1KO), empty vector transfected to Jag1KO, and JAG1 rescued to Jag1KO cocultured with mouse embryonic fibroblasts (MEFs) as spheroids were used to compare the ECM proteins by mass spectrometry.
Project description:p63 ChIP-SEQ in a p63 expressing basal-subtype breast cancer cell line, MCFDCIS and in a p63 deficient claudin-low subtype breast cancer cell line, MDA-MB-231 p63 ChIP-SEQ on MCFDCIS and MDA-MB-231 cell lines
Project description:To identify typical enhancers and super-enhancers in the MDA-MB-231 triple-negative breast cancer cell line, we performed ChIP-seq using DNA isolated from untreated MDA-MB-231 cells using an H3K27ac antibody.
Project description:Membrane-derived extracellular vesicles, referred to as microvesicles (MVs), have been proposed to participate in several cancer diseases. In this study, MV fractions were isolated by differential ultracentrifugation from a metastatic breast cancer (BC) cell line MDA-MB-231 and a non-cancerous breast cell line MCF10A, then analyzed by nano-liquid chromatography coupled to tandem mass spectrometry. A total of 1,519 MV proteins were identified from both cell lines. The data obtained were compared to previously analyzed proteins from small extracellular vesicle (sEV), revealing 1,272 proteins present in both MVs and sEVs derived from the MDA-MB-231 cell line. Among the 89 proteins unique to MDA-MB-231 MVs, three enzymes: ornithine aminotransferase (OAT), transaldolase (TALDO1) and bleomycin hydrolase (BLMH) have been previously proposed as cancer therapy targets. These proteins were enzymatically validated in cells, sEVs and MVs derived from both cell lines. The specific activity of OAT and TALDO1 was significantly higher in MDA-MB-231-derived MVs than in MCF10A10A MVs. BLMH was highly expressed in MDA-MB-231-derived MVs, compared to MCF10A MVs. This study shows that MVs carry functional metabolic enzymes and provides a framework for future studies of their biological role in BC and potential in therapeutic applications.
