Project description:Proteomic analysis of EVs produced by DCs differentiated in vitro from blood monocytes isolated from control, initial PD and advanced PD
Project description:Venous thromboembolism (VTE) is a major contributor to morbidity and mortality in patients with advanced lung adenocarcinoma. Extracellular vesicles (EVs) are established mediators of the associated hypercoagulable state. We conducted a transcriptomic analysis of plasma EVs to identify molecular signatures specific to cancer-associated thrombosis (CAT) for refined risk stratification and therapeutic targeting. Methods: Plasma EVs from lung adenocarcinoma patients with (n=10) and without (n=11) VTE were analyzed by RNA-Sequencing. Differentially Expressed Genes (DEGs) were analyzed for pathway enrichment. Results: RNA-Seq identified 483 DEGs in VTE patients, with significant enrichment in pathways related to inflammation, neutrophil degranulation (NETs), and blood coagulation. Conclusion: Plasma EVs carry a potent, multi-cellular derived immuno-thrombotic mRNA signature that distinctly underlies CAT in lung adenocarcinoma.
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.
Project description:Identification of transcriptional profile of several genes involved in diabetes in islet-derived extracellular vesicles (Evs). Recently, EVs are identified as a new mechanism in cell-to-cell communication by transfer of protein and genic information (mRNA, microRNA). Their role is under investigation in immunology, stem cell and cancer, but not in islets and diabetes. The aim of this experiment is to identify mRNA transcripts (in particular, mRNA transcripts involved in diabetes pathophysiology) present in islet Evs.
Project description:As a part of study to characterize the effects of fluid flow shear stress to mouse muscle cells, small RNA sequencing was performed with muscle cell-derived extracellular vesicles (Myo-EVs).
Project description:To identify specific miRNAs carried by hUCMSC-EVs, and explore their crucial roles in hUCMSC-EV-based improvement of inflammatory diseases.
Project description:Extracellular vesicles (EVs) play a crucial role in facilitating intercellular communication. The microRNA profiles carried by EVs often exhibit variations between tumor patients and healthy individuals, making them promising biomarkers. These biomarkers are implicated in oncogenic processes and tumor metastasis upon uptake by recipient cells. To investigate the impact of EV biomarkers on tumorigenesis, we exposed HCT-116 cell lines to EVs isolated from the serum of both tumor patients and healthy individuals. In comparison to cell lines treated with extracellular vesicles (EVs) from healthy individuals and blank controls, cell lines treated with EVs from HCC sources exhibit significant alterations in the expression of certain genes associated with pathways related to liver cancer. Our findings shedlight on the intricate interplay between EVs and tumor progression.
Project description:Vascular calcification often occurs with osteoporosis, a contradictory association called “calcification paradox”. We find that extracellular vesicles (EVs) released from aged bone matrix (AB-EVs) during bone resorption favor adipogenesis rather than osteogenesis of BMSCs and augment calcification of vascular smooth muscle cells (VSMCs). Intravenous or intramedullary injection of AB-EVs promotes bone-fat imbalance and exacerbates Vitamin D3 (VD3)-induced vascular calcification in young or old mice. To explore the involvement of miRNAs in the AB-EVs-induced promotion of adipocyte formation and vascular calcification, the Agilent miRNA array was conducted to compare the miRNA expression profiles in AB-EVs and YB-EVs from mouse bone specimens. Our study uncovers the role of AB-EVs as a messenger for calcification paradox by transferring functional miRNAs.
