Project description:Cells secrete extracellular RNA (exRNA) to their surrounding environment and exRNA has been found in many body fluids such as blood, breast milk and cerebrospinal fluid. However, there are conflicting results regarding the nature of exRNA. Here, we have separated two distinct exRNA profiles released by mast cells, here termed high-density (HD) and low-density (LD) exRNA. The exRNA in both fractions was characterized by microarray and next-generation sequencing. Both exRNA fractions contained mRNA and miRNA, and the mRNAs in the LD exRNA correlated closely with the cellular mRNA, whereas the HD mRNA did not. Furthermore, the HD exRNA was enriched in lincRNA, antisense RNA, vault RNA, snoRNA, and snRNA with little or no evidence of full-length 18S and 28S rRNA. The LD exRNA was enriched in mitochondrial rRNA, mitochondrial tRNA, tRNA, piRNA, Y RNA, and full-length 18S and 28S rRNA. The proteomes of the HD and LD exRNA-containing fractions were determined with LC-MS/MS and analysed with Gene Ontology term finder, which showed that both proteomes were associated with extracellular vesicles. Additionally, the proteins in the HD fractions tended to be associated with the nucleus and ribosomes, whereas the LD fraction proteome tended to be associated with the mitochondrion. We show that the two exRNA signatures released by a single cell type can be separated by floatation on a density gradient. These results show that cells can release multiple types of exRNA with substantial differences in RNA species content. This is important for any future studies determining the nature and function of exRNA released from different cells under different conditions.

Project description:Membrane vesicles released by neoplastic cells into extracellular medium contain potential of carrying arrays of oncogenic molecules including proteins and microRNAs (miRNA). Extracellular (exosome-like) vesicles play a major role in cell-to-cell communication. Thus, the characterization of miRNAs of exosome-like vesicles is imperative in clarifying intercellular signaling as well as identifying disease markers. microarray analysis identified several oncogenic miRNA between the two types vesicles.

The proteomes of the HD and LD exRNA-containing fractions were determined with LC-MS/MS and analysed with Gene Ontology term finder, which showed that both proteomes were associated with the term extracellular vesicles and electron microscopy suggests that at least a part of the exRNA is associated with exosome-like extracellular vesicles. Additionally, the proteins in the HD fractions tended to be associated with the nucleus and ribosomes, whereas the LD fraction proteome tended to be associated with the mitochondrion. We show that the two exRNA signatures released by a single cell type can be separated by floatation on a density gradient.

Project description:Objectives: MicroRNA (miRNA) can be released to the extracellular medium and participates in neuronal communication. We investigate the mechanisms of miRNA exocytosis by vesicle fusion as a neuromodulator in a manner that are disparate from silencing gene expression. Methods: Small RNA sequencing data of large dense-core vesicle were generated by next-generation sequencing (NGS) in triplicate using Illumina Hiseq 2500. Results: Large dense-core vesicles contain a variety of known and novel miRNAs inside including miR-375. Conclusion: miRNAs can be novel neuromodulators, which are stored in LDCVs and released by vesicle fusion by SNARE assembly and synaptotagmin-1

Project description:Extracellular vesicles (EVs) are mammalian cell-derived nano-scale structures enclosed by a lipid bilayer that were previously considered to be cell debris with little biological value. However, EVs are now recognized to possess biological function, acting as a packaging, transport and delivery mechanism by which functional molecules (i.e. miRNAs) can be transferred to target cells over some distance. To examine the miRNA from keratinocyte-derived EVs, we isolated three distinct populations of EVs from both HaCaT and primary human keratinocytes (PKCs) and characterized their biophysical, biochemical and functional features by using microscopy, immunoblotting, nanoparticle tracking, and next generation sequencing. We identified 1048; 906; and, 704 miRNAs, respectively, in apoptotic bodies (APs), microvesicles (MVs) and exosomes (EXs) released from HaCaT, and 608; 506; and, 622 miRNAs in APs, MVs and EXs released from PKCs. In which, there were 623 and 437 identified miRNAs common to three HaCaT-derived EVs and PKC-derived EVs, respectively. In addition, we found hundreds of exosomal miRNAs that were previously un-reported and that differences in the abundance levels of the identified EV miRNAs could discriminate between the three EV populations. These data contribute to EV-identified miRNA database, especially keratinocyte-derived EV miRNA content.

Project description:Epididymosomes are small membrane vesicles (50-500nm) secreted by epididymal epithelial cells and involved in post-testicular sperm maturation. While their role in protein transfer to the sperm membrane is well acknowledged, we unveil here their capacity to vehicle microRNAs (miRNAs), which are potent regulators of post-transcriptional gene expression. Using a global microarray approach, we showed that epididymosomes providing from two discrete bovine epididymal regions (caput and cauda) possess distinct miRNA signatures. In addition, we established that miRNA repertoires contained in epididymosomes differ from those of their parent epithelial cells, suggesting that miRNA populations released from the cells may be selectively sorted. Binding of DilC12-labeled epididymosomes to primary cultured epididymal cells was measured by flow cytometry and indicated that epididymosomes from the median caput and their miRNA content may be incorporated into distal caput epithelial cells. Overall, these findings reveal that distinct miRNA repertoires are released into the intraluminal fluid in a region-specific manner and could be involved in a novel mechanism of intercellular communication throughout the epididymis via epididymosomes.
