Project description:Chronic kidney disease (CKD) accelerates vascular calcification (VC) via phenotypic switching of vascular smooth muscle cells (VSMCs). We investigated the roles of circulating small extracellular vesicles (sEVs) between the kidneys and VSMCs and uncovered relevant sEV-propagated microRNAs (miRNAs) and their biological signaling pathways. We established CKD models in rats and mice by adenine-induced tubulointerstitial fibrosis. The miRNA transcriptome of sEVs revealed a depletion of several miRNAs in CKD. Their expression levels in sEVs from CKD patients were correlated to kidney function. This study revealed the transcriptomic landscape of miRNAs propagated in sEVs in CKD. We investigated the therapeutic potential of miRNAs in VC.
Project description:Comparative RNA profiling between tumor cells and their secreted extracellular vesicles. Results revealed enrichment in genes involved in cellular migration and metastasis in extracellular vesicles, in agreement with their role as mediators of tumor progression. Mice were orthotoplically transplanted with MDA-MB-231 Breast Adenocarcinoma cells. Cells and extracellular vesicles (EVs) from the resulting tumors were isolated. EVs were characterized by electron microscopy and Nanoparticle Tracking Analysis before total RNA isolation for comparative analysis with cellular RNA. Three biological replicates were analyzed in (technical) duplicate.
Project description:To determine whether the microRNA content of CSF vesicles changes throughout life we performed experiments including miRNA microarrays. Hierarchical clustering analysis indicated that the miRNA content of CSF vesicles changes when patients less than 2 years are compared to those older than 70 years of age. CSF vesicles were fractionated and isolated from patients of different ages, total RNA extracted, and subjected to miRNA microarray analysis
Project description:We report the application of FAIRE seq and ChIP seq in breast cancer cell line, MDAMB231. Examination of FAIRE and ChIP assay in MDAMB231
Project description:Total RNA secreted or excreted by C. elegans incubated for 5h or 24h in M9 culture media and isolated. Extracellular vesicles were isolated by differential ultracentrifugation, and subjected to miRNA sequencing.
Project description:We analyzed ChIP-seq profiles for H3K4me3, H3K27ac, BRG1, ARID1A, PPAR? and JMJD1A and FAIRE-seq open chromatin profile in immortalized brown adipocytes (iBATs) treated with 1 ?M isporoterenol (ISO) or vehicle for 2 hr ChIP-seq profiles for H3K4me3, H3K27ac, BRG1, ARID1A, PPAR? and JMJD1A and FAIRE-seq open chromatin profile in iBATs at Day 8 of differentiation treated with 1 ?M isporoterenol (ISO) or vehicle for 2 hr
