Project description:Human mesenchymal stem cell (hMSC) derived extracellular vesicles (EVs) have shown therapeutic potential in recent studies. However, the corresponding therapeutic components are largely unknown, and scale-up production of hMSC EVs is a major challenge for translational applications. In the current study, hMSCs were grown as 3D aggregates under wave motion to promote EV secretion. Results demonstrate that 3D hMSC aggregates promote activation of the endosomal sorting complexes required for transport (ESCRT)-dependent and -independent pathways. mRNA sequencing revealed global transcriptome alterations for 3D hMSC aggregates. Compared to 2D-hMSC-EVs, the quantity of 3D-hMSC-EVs was enhanced significantly (by 2-fold), with smaller sizes, higher miR-21 and miR-22 expression, and an altered protein cargo (e.g., upregulation of cytokines and anti-inflammatory factors) uncovered by proteomics analysis, possibly due to altered EV biogenesis. Functionally, 3D-hMSC-EVs rejuvenated senescent stem cells and exhibited enhanced immunomodulatory potentials. In summary, this study provides a promising strategy for scalable production of high-quality EVs from hMSCs with enhanced therapeutic potential.

Project description:Extracellular vesicles (EVs) contain proteins, enzymes and metabolites that contribute to the therapeutic potential of human mesenchymal stem cells (hMSCs). However, scale-up production of hMSC EVs has become a major challenge. In current study, hMSCs were grown as 3D aggregates under wave motion to promote EV secretion (3D EVs). mRNA sequencing reveals global transcriptome alterations (e.g., upregulated Wnt, TNF, and Hippo signaling and downregulated cellular senescence) for 3D aggregates. Compared to 2D EVs, the quantity of 3D EVs was enhanced significantly with smaller size, higher miR-21 and miR-22 expression, and the altered protein cargo revealed by proteomics. 3D hMSC aggregates promote activation of the endosomal sorting complexes required for transport (ESCRT) pathway and ESCRT-independent pathway. In addition, 3D EVs rejuvenated stem cells expressing cellular senescence and modulated immune response determined by T lymphocyte and macrophage phenotype assays. In summary, this study provides a promising strategy for high-quality EV production from hMSCs with enhanced therapeutic potentials.

Project description:Colorectal cancer (CRC) shows the high mortality and morbidity. The mortal number of patients and the morbid number of patients with CRC is also increasing. However, the genes which relate to promote tumorigenesis in CRC remain unclear. In order to investigate specific genes and pathways involved in CRC tumorigenesis, we compared genes expressed between three dimensional cultures and control two-dimensional cultures. Total RNA was prepared from the CRC cell lines under the condition of two-dimensional culture and three dimensional culture.

Project description:Similar to bacterial proteins that are targeted to distinct macrophages organelles via extracellular vesicles, we propose that these vesicles also traffic small RNAs to modulate specific host factors. To test this, we aim to sequence extracellular vesicle derived sRNA, and whole bacterial small RNAs to determine selectivity, and to identify their bacterial and mammalian targets (Experimental Plan in Table-1). For this we will collect highly purified vesicles from N. gonorrhoeae (strain MS11A). We will also treat mouse derived primary macrophages with extracellular vesicles and compare their RNA response to untreated macrophages (Table-2). This will provide novel insights into how macrophages respond to N. gonorrhoeae infections. This data is part of a pre-publication release.

Project description:Background: There is some evidence demonstrating the effect of psychological interventions in improvements in health biological parameters. To best of our knowledge, no study had addressed the impact of any psychological intervention on extracellular vesicles. In addition, Mindfulness-Based Cognitive Therapy (MBCT) and Emotion Focused Therapy for Cancer Recovery (EFT-CR) in the group have never been explored regarding extracellular vesicles and the effectiveness of these was not compared yet.
Objectives:
1. To explore and compare the effect of MBCT and EFT-CR on biological parameters and psychological variables in distressed people who have had breast, prostate and colorectal cancer;
2. In addition, we will explore the acceptability through recruitment and retention rates of MBCT and EFT-CR in group and evaluate whether these interventions are appropriate for a larger clinical trial.
Methods: The design of this study is a parallel randomized controlled trial. Participants will be randomized into MBCT, EFT-CR or usual care. Outcome measures will be assessed before, at the end of the intervention (8 weeks) and follow-ups (24 and 52 weeks from the baseline moment).
Hypotheses: The researchers expected that both interventions will have an effect on extracellular vesicles and other study biomarkers as well as improvements in psychological outcomes, compared to treatment as usual (TAU) group. Regarding the comparative effectiveness, we did not have evidence to hypothesize which one of the interventions will be superior in both biological (extracellular vesicles) and psychological outcomes.
Contribution for practice: The results of this preliminary study would permit to know if there are benefits of these psychological interventions on changes in extracellular vesicles and on psychological outcomes related to health. In addition, this study will permit to determine the acceptability of conducting a larger randomized controlled trial.

Project description:To further investigate the molecular mechanisms by which EVs mediated the abnormal localization of tight junction proteins and adherence junction protein, we performed miRNA microarray analysis of extracellular vesicles isolated from breast cancer cells. miRNA expression in extracellular vesicles was collected from MDA-MB-231-D3H1, MDA-MB-231-D3H2LN, BMD2a and BMD2b breast cancer cell lines.
