NanoString assays of miRNA in MCF7 and MCF10A cells and in extracellular vesicles (EVs) derived from these cells.

Project description:The goal of this study is to identify unique miRNA profiles of EVs from MCF7 and MCF10A cells that distinguish their cellular origin. 654 human mature miRNAs were analyzed in NanoString assays to identify miRNA with high abundance in MCF7 EVs and the greatest fold change for MCF7 EVs relative to MCF10A EVs.

Differential Gene Expression between MCF10A and MCF7 cells

Project description:These RNA-seq data were generated to correlate with genomic interaction data in a related Hi-C analysis. MCF10A is a normal-like mammary epithelial cell line and MCF7 is a transformed estrogen responsive breast cancer cell line derived from a metastatic site; both are commonly used in models of breast cancer progression. Analysis revealed a set of genes related to repression of WNT signalling that were both up-regulated in MCF7 and located in genomic regions that had transitioned from closed to open structure in MCF7. RNA-seq of MCF10A and MCF7 cells. 3 replicates each. Sequencing was strand-specific and conducted on ribo-depleted RNA.

Crosstalk between the effects of extracellular vesicles (Evs) and TNF on U937 human monocyte cell line

Project description:Under physiological conditions, extracellular vesicles (EVs) are present simultaneously in the extracellular compartment together with cytokines. Thus, we hypothesized that EVs in combination with cytokines induce different responses of monocyte cells compared to EVs or cytokines alone. Human monocyte U937 cells were incubated with EV-containing or EV-free CCRF human T-cell supernatant, with or without the addition of TNF. U937 cells cultured in EV-free supernatant, supernatant containing CCRF t-cell derived EVs, TNF or both. Each treatment option was measured in 3 replicates.

RNA-seq of NIH3T3 cells treated with PBS or extracellular vesicles (EV) from MCF10A or MDA-MB-231 cells

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.

Transcriptomics indicate nuclear division and cell adhesion not recapitulated in MCF7 and MCF10A compared to luminal A breast tumours

Project description:To better understand the tumour-modelling efficacy of cell lines, we performed RNA-seq analyses on 2D and 3D cultures of tumourigenic MCF7 and non-tumourigenic MCF10A and augmented our data with published datasets. To our knowledge, this was the first RNA-seq dataset comprising 2D and 3D cultures of MCF7 and MCF10A within the same experiment. We then compared tumourigenesis within cell lines (MCF7-vs-MCF10A) and tumourigenesis within clinical tissues (Luminal A-vs-Normal) from the TCGA-BRCA dataset and considered whether the same cancer-related processes could be observed.

microRNA expression profile in isolated human pancreatic islets and in human pancreatic islet-derived extracellular vesicles -EVs-

Project description:Human pancreatic islets were isolated from pancreas of deceased donors by Ricordi's procedure and cultured in CMRL 1066 medium additioned with human albumin. EVs were isolated from conditioned medium derived from islet culture after isolation. Once isolated, RNA of islets and islet-derived EVs was extracted and analyzed for microRNA expression within 48 hours after isolation.

Effect of long-term education with EVs from women with obesity on MCF7 gene expression

Project description:Breast adipose tissue is an important contributor to the obesity-breast cancer link. Dysregulated cell metabolism is now an accepted hallmark of cancer. Extracellular vesicles (EVs) are nanosized particles containing selective cargo, such as miRNAs, that act locally or circulate to distant sites to modulate target cell functions. Here, we found that long-term education of breast cancer cells (MCF7, T47D) with EVs obtained from breast adipose tissue of women who are overweight or obese (O-EVs) leads to sustained increased proliferative potential. RNA-Seq of O-EV-educated MCF7 cells demonstrates increased expression of genes, such as ATP synthase and NADH: ubiquinone oxidoreductase, involved in oxidative phosphorylation.
