ABSTRACT: To identify gene expression changes associated with treatment of EV that carry high levels of miR-105 (from MDA-MB-231 and MCF10A/miR-105 cells) in human breast tumor derived CAF, we analyzed RNA isolated from PBS- or EV-treated CAF. Gene expression in CAF treated with EV from MDA-MB-231 or MCF10A/miR-105 cells was compared to cells treated with PBS or EV from MCF10A cells, both of which served as controls in this experiment.
Project description:To identify gene expression changes in liver associated with circulating EV that carry high levels of miR-122 (from MDA-MB-231 and MCF10A/miR-122 cells), we analyzed RNA isolated from the liver of PBS- or EV-treated female NOD scid gamma (NSG) mice. Mice had received tail-vein injected EV (or PBS) twice a week for 5 weeks (~10 ug EV per injection). Gene expression in liver from mice treated with EV from MDA-MB-231 or MCF10A/miR-122 cells was compared to cells treated with PBS or EV from MCF10A cells, both of which served as controls in this experiment.
Project description:To identify gene expression changes associated with treatment of EVs from MDA-MB-231 [231] and MCF10A [10A] cells) in NIH3T3 cells, we analyzed RNA isolated from PBS- or EV-treated NIH3T3 cells. Gene expression in NIH3T3 cells treated with EV from MDA-MB-231 cells was compared to cells treated with PBS or EV from MCF10A cells, both of which served as controls in this experiment.
Project description:To compare gene expression changes in skeletal muscle caused by EVs from normal (MCF-10A) and cancer (MDA-MB-231) cells, we analyzed RNA isolated from the GA muscle of EV-treated female NOD scid gamma (NSG) mice. Mice had received tail-vein injections of EVs twice a week for 5 weeks (~10 ug EV per injection). Gene expression in muscle from mice treated with MDA-MB-231-derived EVs was compared to mice treated with MCF-10A-derived EVs.
Project description:This Series reports results of miRNA profiling of estrogen-receptor-positive (MCF7) and estrogen-receptor-negative (MDA-MB-231) cells. Retinoic Acid (RA) induces mir-21 in MCF-7 but not in MDA-MB-231 cells. MCF-7 and MDA-MB-231 cells were treated (or not) with retinoic acid (RA) and grown for either 6 hours or 48 hours.
Project description:To investigate the effects of breast cancer derived EVs on liver metabolism,we inoculated MDA-MB-231,231 /Rab27A KD and 231 /miR-9 KO cells into subcutaneous tumor in NSG mice. We then performed gene expression profiling analysis using data obtained from RNA-seq of liver from mice xenografted MDA-MB-231 cells (tumor bearing) or MDA-MB-231/Rab27A KD cells (231/Rab27A KD) or MDA-MB-231 /miR-9 KO (231/miR-9 KO) and tumor free mice.
Project description:MDA-MB-231 cells were treated with PBS, LPS, IL1b, TNFa, IL6, and TGFb respectively and expression profile were assayed by Arraystar human lncRNA array 2.0
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.
