Integration of miRNA in exosomes and single-cell RNA-seq profiles in endemic osteoarthritis, Kashin-Beck disease

Project description:Kashin-Beck disease (KBD) is an endemic, chronic degenerative joint disease in China. Exosomes miRNAs, as signaling molecules in intercellular communication, can transfer specific biological martials into target cell to regulate the their function and might participate in the pathogenesis of KBD. We isolated serum and chondrocytes-derived exosomes, miRNA sequencing revealed exosomes miRNA profiles and differentially expressed miRNAs (DE-miRNAs) were identified. The target genes were predicted of known and novel DE-miRNAs with TargetScan 5.0 and miRanda 3.3a database. Single-cell RNA sequencing (scRNA-seq) was performed to identify chondrocyte clusters and their gene signatures in KBD. And we performed comparative analysis between the serum and chondrocytes-derived exosomes DE-miRNA target genes and differentially expressed genes of each cell clusters.A total of 20 DE-miRNAs were identified in serum-derived exosomes. In the miRNA expression of chondrocytes-derived exosomes, 53 DE-miRNAs were identified. 16063 predicted targets were identified as the target genes in the serum-derived exosomes, 57316 predicted targets were identified as the target genes in the chondrocytes-derived exosomes. Seven clusters were labelled by cell type according to the expression of previously described markers. 315 common genes were found among serum/chondrocytes-derived exosomes DE-miRNA target genes and DEGs identified by scRNA-seq analysis. We firstly integratly analyzed the serum and chondrocytes exosomes miRNA with single-cell RNA sequencing (scRNA-seq) data of KBD chondrocyte, the results showed that DE-miRNAs in exosomes might play a potential role in regulating genes expression in different KBD chondrocytes clusters by exosomes mediating cell-cell communications functions, which could improve the new diagnosis and treatment methods for KBD.

Expression profiles of transfer RNA-derived small RNAs in serum exosomes from breast cancer patients and healthy controls

Project description:To explore expression levels of tsRNAs in serumal exosomes, 4 serum specimens were chosen from patients with metastatic breast cancer and 4 samples from healthy subjects. The exosomes were isolated and sent for tsRNA-sequencing.

Expression Profile of Serum-related Exosomal miRNAs from Parathyroid Tumor

Project description:Objective: The expression pattern of exosomal miRNAs derived from parathyroid tumor is still unknown. In the present work, we aimed to examine the differences on microRNA (miRNA) expression, present in serum exosomes, by comparing parathyroid carcinoma (PC) and parathyroid adenoma (PA). Methods: MiRNA expression profile of serum exosomes, derived from 4 PC patients and 4 PA patients, were analyzed by next-generation sequencing technology. The differential expressions of target miRNAs were further verified in both serum exosomes and tissues of PC/PA patients by quantitative reverse transcription polymerase chain reaction (qRT-PCR). Lastly, receiver operating characteristic (ROC) curves were plotted to investigate the efficiency of target exosomal miRNAs in distinguishing PC patients from PA controls. Results: Multiple differentially expressed miRNAs of serum exosomes were screened out by sequencing. Based on this screening, hsa-miR-146b-5p (p=0.0846), hsa-miR-27a-5p (p=0.0412), hsa-miR-93-5p (p=0.73), hsa-miR-381-3p (p=0.1239) and hsa-miR-134-5p (p=0.0694) were up-regulated in the serum exosomes of PC patients. These results were validated by qPCR, where the trend on differential miRNA expression was consistent with the sequencing results. Specifically, the expression of exosomal hsa-miR-27a-5p was able to clearly distinguish PC patients from PA controls, and related analysis indicated that the area under the ROC curve was 0.8594 (p=0.0157). Conclusion: Here we present, for the first time, the miRNA expression profile of serum exosomes derived from PC patients. Based on this result, we presently suggest that the exosomal hsa-miR-27a-5p may serve as a putative tumor marker for preoperative identification of PC and PA subjects.

Investigation of differential microRNAs in the exosomes of alcohol-induced H9c2 myocardial cells

Project description:We use the illumina high-throughput sequencing technology to identify miRNAs between the exosomes of H9c2 cells with or without alcohol-induced.The H9c2 cells were cultured in serum-free medium and stimulated with ethanol (100 mmol/L) or PBS for 24 h, then collected the exosomes samples from serum-free medium. Exosomes were isolated and extracted by differential centrifugation and detected by electron microscopy, particle size and related marker proteins.In total, 123 differentially expressed miRNAs (12 upregulated and 111 downregulated) were screened by miRNA sequence.
