Project description:In the present study we analyzed miRNA and mRNA expression profiles in human peripheral blood lymphocytes (PBLs) incubated in microgravity condition, simulated by a ground-based Rotating Wall Vessel (RWV) bioreactor. Our results show that 42 miRNAs were differentially expressed in MMG-incubated PBLs compared with 1g-incubated ones. Among these, miR-9-5p, miR-9-3p, miR-155-5p, miR-150-3p, and miR-378-3p were the most dysregulated. To improve the detection of functional miRNA-mRNA pairs we performed gene expression profiles on the same samples assayed for miRNA profiling and we integrated miRNA and mRNA expression data. The functional classification of miRNA-correlated genes evidenced significant enrichments in the biological processes of immune/inflammatory response, signal transduction, regulation of response to stress, regulation of programmed cell death and regulation of cell proliferation. We identified the correlation between miR-9-3p, miR-155-5p, miR-150-3p and miR-378-3p expression with that of genes involved in immune/inflammatory response (eg. IFNG and IL17F), apoptosis (eg. PDCD4 and PTEN) and cell proliferation (eg. NKX3-1 and GADD45A). Experimental assays of cell viability and apoptosis induction validated the results obtained by bioinformatics analyses demonstrating that in human PBLs the exposure to reduced gravitational force increases the frequency of apoptosis and decreases cell proliferation.

Analyses were performed by using the M-bM-^@M-^\Human miRNA Microarray kit (V2)M-bM-^@M-^] (Agilent Technologies), that allows the detection of 723 known human (miRBase v.10.1) and 76 human viral miRNAs.By comparing the expression profile of MMG-incubated vs. 1g-incubated PBLs of the same donor, we found 42 differentially expressed miRNAs, 25 up-regulated and 17 down-regulated.

Project description:Recent evidence suggests that hypoxia caused by acute myocardial infarction (AMI) can induce evident cardiomyocyte apoptosis. Exosomes, as paracrine signaling mediators by delivering cytosolic components (including miRNA, mRNA, protein), play crucial roles in intercellular communication. However, the systemic regulation of exosome-mediated miRNA delivery and subsequent regulation effect underlying AMI are not well-understood to date. Here, using small RNA-seq, we investigated the miRNAome of H9C2 cells and corresponding paracrine exosmes after hypoxia stress, and identified total of 92 and 62 differentially expressed (DE) miRNAs in cells and exosomes from hypoxia vs. normoxia condition. We found that hypoxia strongly induced the expression of hypoxamiRs in H9C2 cells and altered cardiomyocyte-derived exosomal miRNAome. Functional enrichment analysis revealed extensive roles of DE exosomal miRNAs in HIF-1 signaling pathway and cell apoptosis process, such as TNF signaling pathway, MAPK signaling pathway, mTOR signaling pathway. Furthermore, the gain- and loss-of-function analysis demonstrated the anti-apoptotic effects of hypoxia-induced exosomal miRNAs, i.e. miR-21-5p, miR-378-3p, miR-152-3p, let-7i-5p, and then the luciferase reporter assay confirmed that miR-152-3p and let-7i-5p implemented their anti-apoptotic function by directly targeting Atg12 and Faslg, respectively. In short, this study revealed that hypoxia-exosomes derived from cardiomyocyte, loaded abundant cardio-protective miRNAs, mediate crosstalk among cardiomyocytes and prevent cardiomyocytes apoptosis after hypoxia. Methods: we established the anoxia model using H9C2 cells, an immortal cardiac muscle cell line, to imitate hypoxia condition caused by AMI in vitro, and then small RNA-seq were employed to investigate the miRNA transcriptome of H9C2 cells and its exosomes collected from hypoxia and normoxia culture medium. Results: we identified the miRNAome of H9C2 cells and its exosmes under both hypoxia and normoxia, including 331, 338, 144, 74 unique mature miRNAs from hypoxia-cells, normoxia-cells, hypoxia-exosomes, normoxia-exosomes, respectively. Total of 92 and 62 DE miRNAs were identified from cells and exosomes. Among of which, the DE exosomal miRNAs were mainly involved in HIF-1 signaling pathway and cell apoptosis process, such as TNF signaling pathway, MAPK signaling pathway, mTOR signaling pathway. Interestingly, we found that some DE exosomal miRNAs, including miR-21-5p, miR-378-3p, miR-152-3p, let-7i-5p, have an anti-apoptotic and pro-viability effects in H9C2 cells under hypoxic stress. In addition, Atg12 and Faslg to be respective target of miR-152-3p and let-7i-5p were partly elucidated the anti-apoptosis mechanism of hypoxia-exosomes. Conclusions:In brief, this study illustrated a potential mechanism that, under hypoxic stress, hypoxia pre-perceived cardiomyocytes can spontaneously secrete the hypoxamiRs enriched exosomes, loaded a large amount of cardio-protective miRNA, which mediate crosstalk among cardiomyocytes and prevent apoptosis to heighten the hypoxia adaptability of cardiomyocytes. In more detail, we first discovered that miR-152-3p and let-7i-5p, enriched in hypoxia-exosomes derived by cardiomyocytes, played an anti-apoptosis role via mitochondrial pathway(intrinsic pathway) and death receptor pathway (extrinsic pathway), respectively.

Project description:MiRNAs regulate posttranscriptional gene expression and are widely implicated in the pathogenesis of complex diseases. We aim to elucidate miRNA regulation of the atrial mRNA signatures that associate with AF. This may provide novel mechanistical insights and candidate targets for therapies using miRNA mimics or antimiRs.
We present combined miRNAs-mRNAs sequencing in atrial tissues of patient without AF (n=22), with paroxysmal AF (n=22) and with persistent AF (n=20). MiRNA and mRNA signatures followed an ordinal scale from nonAF to paroxysmal to persistent AF patients. The previously reported mRNA sequencing identified 5228 differentially expressed genes involved in epithelial to mesenchymal transition, endothelial cell proliferation and extracellular matrix remodelling involving collagens, glycoproteins and proteoglycans. We discovered 103 differentially expressed miRNAs. Key downregulated miRNAs included miR-135b-5p, miR-138-5p, miR-200a-3p, miR-200b-3p and miR-31-5p and key upregulated miRNAs were miR-144-3p, miR-15b-3p, miR-182-5p miR-18b-5p, miR-4306 and miR-206. The expression levels of differentially expressed miRNAs were negatively correlated with the expression levels of their predicted target mRNAs. The downregulated miRNAs demonstrated a more profound transcriptome effect than the upregulated miRNAs. Upregulated biological processes enriched in miRNAs targets related to epithelial and endothelial cell migration and glycosaminoglycan biosynthesis, in line with the processes discovered by the mRNA sequencing analysis.
Combined analysis of miRNA and mRNA sequencing uncovered miRNAs with a broad transcriptional effect in human AF. Epithelial to mesenchymal transition and endothelial cell proliferation were processes controlled by downregulated miR-135b-5p, miR-138-5p, miR-200a-3p, miR-200b-3p and miR-31-5p, which in turn may contribute to (myo)fibroblast activation and structural remodeling.\

Project description:Malignant germ-cell-tumours (GCTs) are characterised by microRNA (miRNA/miR-) dysregulation, with universal over-expression of miR-371~373 and miR-302/367 clusters regardless of patient age, tumour site, or subtype (seminoma/yolk-sac-tumour/embryonal carcinoma). These miRNAs are released into the bloodstream, presumed within extracellular-vesicles (EVs) and represent promising biomarkers. Here, we comprehensively examined the role of EVs, and their miRNA cargo, on (fibroblast/endothelial/macrophage) cells representative of the testicular GCT (TGCT) tumour microenvironment (TME). Small RNA next-generation-sequencing was performed on 34 samples, comprising representative malignant GCT cell lines/EVs and controls (testis fibroblast [Hs1.Tes] cell-line/EVs and testis/ovary samples). TME cells received TGCT co-culture, TGCT-derived EVs, and a miRNA overexpression system (miR-371a-OE) to assess functional relevance. TGCT cells secreted EVs into culture media. MiR-371~373 and miR-302/367 cluster miRNAs were overexpressed in all TGCT cells/subtypes compared with control cells and were highly abundant in TGCT-derived EVs, with miR-371a-3p/miR-371a-5p the most abundant. TGCT co-culture resulted in increased levels of miRNAs from the miR-371~373 and miR-302/367 clusters in TME (fibroblast) cells. Next, fluorescent labelling demonstrated TGCT-derived EVs were internalised by all TME (fibroblast/endothelial/macrophage) cells. TME (fibroblast/endothelial) cell treatment with EVs derived from different TGCT subtypes resulted in increased miR-371~373 and miR-302/367 miRNA levels, and other generic (eg, miR-205-5p/miR-148-3p) and subtype-specific (seminoma, eg, miR-203a-3p; yolk-sac-tumour, eg, miR-375-3p) miRNAs. MiR-371a-OE in TME cells resulted in increased collagen contraction (fibroblasts) and angiogenesis (endothelial cells), via direct mRNA downregulation and alteration of relevant pathways. TGCT cells communicate with nontumour stromal TME cells through release of EVs enriched in oncogenic miRNAs, potentially contributing to tumour progression.

Project description:Hyperglycemia is a hallmark in prediabetes and type 2 diabetes mellitus (T2DM) which increases risk of micro and macrovascular complications such as diabetic retinopathy, diabetic nephropathy (microvascular complications), and peripheral vascular disease, cerebrovascular disease and cardiovascular diseases (macrovascular complications). Endothelial cells are affected in both cases. In this study, we investigated the miRNA expression changes in HUVECs during different glucose treatment (5mM, 10mM, 25mM and 40mM glucose) at various time intervals (6, 12, 24 and 48hrs). The results of miRNA microarray showed there is a correlation between hyperglycemia induced endothelial dysfunction and miRNA expression. In silico prediction showed that the following pathways: Regulation of actin cytoskeleton, PI3K-Akt signaling pathway, Apoptosis, Neurotrophin signaling pathway, and Insulin signaling pathway, were dysregulated during hyperglycemia. Majority of the pathways are related to apoptosis. 10 miRNAs (miR-26a-5p, -26b-5p, 29b-3p, 29c-3p, 125b-1-3p, -130b-3p, - 140-5p, -221-3p, -192-5p, and -320a,) showed increased expression with increasing concentration of glucose treatment. miR-26a-5p, -29b-3p, - 140-5p, -221-3p, and -192-5p are involves in endothelial apoptosis. Our study revealed miRNAs (miR-29b-3p and – 192-5p) with known mRNA targets (BCL2 and MCL1) showed expression pattern inversely correlating with their respective target mRNAs. Therefore these miRNAs could involve in the endothelial dysfunction due to hyperglycemia.
