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.

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:Human neurodevelopment requires differentiating neurons to establish large networks of connections in a highly stereotyped manner. Neuronal differentiation in particular, requires RNA-binding proteins to spatiotemporally regulate thousands of different mRNAs. Yet, how these proteins precisely relate to neuronal development and coordinate the expression of functionally coherent genes in a cell type specific manner is only partially understood. To address this, we sought to understand how the paradigmatic RNA-binding protein IMP1/IGF2BP1, an essential developmental factor, selects and regulates its RNA targets transcriptome-wide during the differentiation of human neurons. We used a combination of systemic and molecular analyses to show that IMP1 directly binds to and regulates the expression of a large set of mRNAs that govern microtubule assembly, an essential process and a key driver of neuronal differentiation. We also show that m6A methylation during the transition from neural precursors to neurons drives both the selection of IMP1 mRNA targets and their translation potential. Our findings establish m6A methylation as a key mechanism coordinating the regulatory action of IMP1 on human neuronal architecture.

Project description: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.

Project description:A growing body of evidence in mammalian cells indicates that secreted vesicles can be used to mediate intercellular communication processes by transferring various bioactive molecules, including mRNAs and microRNAs. Based on these findings, we decided to analyze whether T. cruzi-derived extracellular vesicles contain RNA molecules and performed a deep sequencing and genome-wide analysis of a size-fractioned cDNA library (16M-bM-^@M-^S40 nt) from extracellular vesicles secreted by noninfective epimastigote and infective metacyclic trypomastigote forms. Our data show that the small RNAs contained in these extracellular vesicles originate from multiple sources, including tRNAs. In addition, our results reveal that the variety and expression of small RNAs are different between parasite stages, suggesting diverse functions. Taken together, these observations call attention to the potential regulatory functions that these RNAs might play once transferred between parasites and/or to mammalian host cells. Small RNAs profiles (16-40 nt) of epimastigote-derived extracellular vesicles, metacyclic trypomastigote-derived extracellular vesicles and metacyclic trypomastigote parental cells.
