The effect of colorectal cancer (CRC) organoid-derived extracellular vesicles on the expression profile of fibroblasts

ABSTRACT: Extracellular vesicles (EV) are membrane-surrounded vesicles secreted by cells that carry biologically important molecules to the target cells. EVs form a heterogenous group and they represent a novel way of intercellular communication. To study the importance of colorectal cancer (CRC)-derived EVs on stromal fibroblasts, we applied CRC patient-derived 3D organoid cultures and commercially available human colon fibroblasts. We studied the gene expression changes in fibroblasts in the presence and absence pf CRC-derived EVs.

The influence of melanoma extracellular vesicles on benign melanocytes, dermal fibroblasts and microvascular endothelial cells (part1)

Project description:This study investigates the role of PRAME (Preferentially Expressed Antigen in Melanoma), a cancer-testis antigen, in melanoma progression, particularly its function in melanoma-derived extracellular vesicles (EVs) and its impact on benign primary melanocytes (PM), primary fibroblasts(PF) and microvascular endothelial cells (EN).

Effects of (−)-Epigallocatechin-3-O-gallate (EGCG) on miRNAs’ expression in extracellular vesicles (EVs) derived from human umbilical vein endothelial cells (HUVECs)

Project description:EGCG, one of the major catechins in green tea, exerts an antifibrotic property, although its mechanism remains unclear. Recently, it has been reported that microRNA (miRNA) transported by extracellular vesicles (EVs) from vascular endothelial cells (VECs) are involved in PF. In this study, we assessed the effects of EGCG on miRNAs’ expression in EVs derived from HUVECs.

Questioning the purity of the media - Extracellular small non-coding RNA contaminants in fetal bovine serum and serum-free media

Project description:In the research field of extracellular vesicles (EVs), the use of EV-depleted fetal bovine serum (FBS) for in vitro studies is highly recommended to eliminate the confounding effects of media derived EVs. EV-depleted FBS may either be prepared by ultracentrifugation or bought commercially, nevertheless these depletion methods do not guarantee an RNA-free preparation. In this study we have addressed the RNA contamination issue in FBS, ultracentrifuged EV-depleted FBS, commercially available EV-depleted FBS, and also from our recently developed filtration based EV depleted FBS. Commercially available serum-free, xeno-free defined media were also screened for RNA contamination.

The human pericardial fluid is enriched with cardiovascular-expressed microRNAs

Project description:The pericardial fluid (PF) surrounds the heart and it is contained in the pericardial sac. PF contains myocardial-derived factors. MicroRNAs (miRNAs) are negative post-transcriptional regulators of their target genes and they can be released into extracellular vesicles (EVs) contributing to cell-to-cell communication. We hypothesize that the PF contains miRNAs of myocardial origin and that represents a niche for the exchange of miRNAs between heart cells. In order to investigate whether PF contains functionally active miRNAs, miRNA expression profiles on PF samples collected from three patients undergoing aortic valve replacement (AVR) surgery performed during cardiopulmonary-bypass (CPB), were genereted.

The transcriptome profile of the stomach fibroblasts with high-metastatic or low-metastatic gastric cancer cell-derived extracellular vesicles.

Project description:Cancer-associated fibroblasts (CAFs) have an important role in the tumor progression. CAFs are heterogeneous, and its subpopulation with distinct functions have been regarded as the major obstacle to CAF targeting therapy. However, it is still unclear how cancer cells mediate CAF subpopulations and create preferable tumor microenvironment for their metastasis. In this study, by using the metastatic cancer cell line models of diffuse-type gastric cancer (DGC), we demonstrate that high-metastatic cancer cell-derived extracellular vesicles (EVs) contribute to the formation of activated fibroblast subpopulations. High-metastatic DGC cells create at least two types of CAF subpopulations: myofibroblastic feature and chemokine producing feature. The CAF subpopulation with chemokine producing feature was selectively induced by high-metastatic DGC cell-derived EVs. We also found that high-metastatic DGC cell-derived EVs contain various miRNAs to induce chemokine expression in the fibroblasts. Our findings suggest that intercellular communications via EVs contribute to establishing the appropriate tumor microenvironment toward cancer metastasis. To study the effect of EVs derived from GC cell lines on gene expression in the stomach fibroblasts, transcriptome analysis for the stomach fibroblasts with EVs derived from GC cell lines was performed.

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.
