Dual targeted extracellular vesicles regulating oncogenic genes in pancreatic cancer [sRNAseq]

Project description:Pancreatic ductal adenocarcinoma (PDAC) tumors carry multiple gene mutations and respond poorly to treatments. There is currently an unmet need for drug carriers that can deliver multiple gene cargoes to high solid tumor burden like PDAC. Here, we report a dual-targeted extracellular vesicle (EV) carrying high loads of RNA that effectively suppresses large PDAC tumors in mice. The EV surface contains a CD64 protein that has a tissue targeting peptide and a humanized monoclonal antibody. Cells sequentially transfected with plasmid DNAs encoding for the RNA and protein of interest by Transwell®-based asymmetric cell electroporation released abundant targeted EVs with high RNA loading. Together with a low dose chemotherapy drug, Gemcitabine, dual-targeted EVs effectively suppressed large orthotopic PANC-1 and patient derived xenograft tumors in mice and extended animal survival. This work presents a clinically accessible and scalable way to produce abundant EVs for delivering multiple gene cargoes to large solid tumors.

Impact of Group Psychological Interventions on Extracellular Vesicles in People Who Had Cancer

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.

miRNA expression of extracellular vesicles

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.
