Circulating miR-4763-3p is a novel potential biomarker candidate for human adult fulminant myocarditis

Project description:Circulating miRNA expression profiles were detected by microarray analysis.qPCR arrays were performed to validate the potential miRNAs.KEGG pathway analysis was used to determine the critical roles of these circulating miRNAs in FM. Correlation analysis was employed between miRNAs and the parameters of cardiac functions in FM. The sensitivity and specificity of circulating lncRNA expression in FM diagnosis were evaluated using receiver operating characteristic curve analysis. Microarray and qPCR analysis showed that the expression of miR-4763-3p and miR-4281 were up-regulated in the plasma of FM at the onset, and their levels were restored as the clinical symptom recovered. The predicted target genes of miR-4763-3p and miR-4281 are involved in several pathways, mainly inflammatory and cardiac injury response. Moreover, the miRNAs enrichment was negatively correlated with the severity of FM. In addition, the expression levels of circulating miR-4763-3p was unchanged in MI and patients and miR-4281 showed high sensitivity and specificity for FM diagnosis.This study provides global profile of circulating miRNAs in patients with FM, among which miR-4763-3p and miR-4281 could serve as potential biomarkers.

Differential expression profiles of plasma tsRNAs in children with fulminant myocarditis

Project description:We report the application of high-throughput RNA sequencing technology to examine expression profiling of plasma transfer RNA (tRNA)-derived small RNAs (tsRNAs) in children with fulminant myocarditis during acute phase (FM-A group), children with fulminant myocarditis during convalescent phase (FM-C group), and healthy volunteers (Con group). A total of 750 precisely matched tsRNAs were identified in the plasma from the three groups. We find that a total of 13 tsRNAs were differentially expressed in FM-A and CON samples, of which 11 tsRNAs were upregulated and 2 were downregulated, and 694 tsRNAs were excluded ; a total of 8 tsRNAs were differentially expressed in paired FM-C and CON samples, of which 2 tsRNAs were upregulated and 6 were downregulated and 703 tsRNAs were excluded . This study provides new ideas for future research on elucidating the mechanisms of myocarditis through regulating tsRNAs levels.

Plasma exosomal miRNA profiles in pediatric fulminant myocarditis patients and healthy controls

Project description:The pathophysiology of fulminant myocarditis (FM) is significantly influenced by the interactions between immunological and myocardial cells, involving exosome-mediated intercellular microRNA (miRNA) signaling. To further investigate the pathogenesis of FM and discover diagnostic biomarkers, we have employed miRNA microarray expression profiling as a discovery platform.

Differential expression profiles and functional analysis of circulating small extracellular vesicle-derived lncRNA in children with fulminant myocarditis

Project description:Fulminant myocarditis (FM) is the most serious type of childhood myocarditis. However, the molecular mechanism underlying the pathogenesis of FM has not been fully elucidated. Studies have shown that small extracellular vesicles (sEVs) play important roles in many diseases, but any potential role of sEVs in pediatric FM has not been reported. Here, the differential expression profiles of lncRNAs in plasma sEVs were studied in five children with FM and five healthy children using whole transcriptome sequencing, followed by functional analysis and screening of immune-related target genes. A total of 68 up-regulated and 11 down-regulated differentially expressed sEVs-lncRNAs were identified. Functional analysis showed that the differentially-expressed sEVs-lncRNAs were mainly involved in immune processes, apoptosis, and protein efflux. Further analysis of immune-related target genes revealed that differentially expressed sEVs-lncRNAs were closely related to immune activation, immune cell migration and cytokine pathway signal transduction in FM. Thus, sEVs-lncRNAs may play an important role in the pathogenesis of FM in children

Serum exosomal miRNA profiles in fulminant myocarditis patients and healthy controls

Project description:Purpose: Exosome-derived microRNAs (miRNAs) are potential diagnostic biomarkers. However, little is known about their effectiveness as diagnostic biomarkers of fulminant myocarditis (FM). This study aimed to explore miRNA levels in serum exosomes of patients with FM as potential biomarkers for FM diagnosis. Methods: 10 samples were screened with a exosomal small RNA sequencing platform (RiboBio). A Mann-Whitney test was performed to discover differentially expressed miRNAs in the two pairwise comparisons: FM versus HC. Results: From the differentially expressed miRNAs, fourteen candidate miRNAs discovered via small RNA sequencing with P＜0.05 and fold expression change ＞2 were selected for further testing Conclusions: These data suggested that the miRNA panel in serum-derived exosomes provided excellent diagnostic capability for FM.

Soluble ST2 induces cardiac contractile dysfunction by repressing mitochondrial electron transport chain genes in cardiomyocytes during fulminant myocarditis

Project description:Fulminant myocarditis (FM) is an acute fatal disease characterised by myocardial inflammation. Our previous study identified soluble growth stimulation- expressed gene 2 (sST2) as a sensitive and specific biomarker for early diagnosis of FM. However, its function in FM remains unclear.In the present study, we observed a marked elevation of sST2 in the plasma and hearts of mice with FM induced by coxsackievirus B3 (CVB3) and explored the main cellular sources of sST2 in FM. Moreover, using recombinant sST2 protein administration and unbiased transcriptomics analyses, we investigated the role and underlying mechanisms of sST2 in FM. Importantly, we found that sST2 has a novel non-classical function in cardiomyocytes, other than acting as an IL-33 decoy receptor. These findings reveal a novel role and action mechanism of sST2 in FM and suggest that sST2 may be a potential therapeutic target for FM.

Bioinformatics Multivariate Analysis Determined a Set of Phase-Specific Biomarker Candidates in a Novel Mouse Model for Viral Myocarditis

Project description:Myocarditis is an inflammatory disease in the heart and is mainly caused by viral infections. Viral myocarditis has been proposed to be divided into three phases; the acute viral phase, the subacute immune phase, and the chronic cardiac remodeling phase. Although individualized therapy should be applied depending on the phase, no clinical or experimental studies have found biomarkers that distinguish between the three phases of myocarditis. Theiler’s murine encephalomyelitis virus (TMEV) belongs to the genus Cardiovirus, and can cause myocarditis in susceptible mouse strains. Using this novel model for viral myocarditis induced with TMEV, we conducted multivariate analysis including echocardiography, serum troponin and viral RNA titration, and microarray for identifying the biomarker candidates that discriminate the three phases. Using C3H mice infected with TMEV on 4, 7, and 60 days post infection (p.i.), we conducted bioinformatics analyses, including principal component analysis (PCA) of microarray data, since our traditional cardiac and serum assays, including two-way comparison of microarray data, did not lead to the identification of a single biomarker. PCA separated heart samples clearly between the groups of 4, 7, and 60 days p.i. Representative genes contributing to the separation were as follows: 4 and 7 days p.i., innate immunity-related genes, such as Irf7, and Cxcl9; 7 and 60 days p.i., acquired immunity-related genes, such as Cd3g and H2-Aa; and cardiac remodeling-related genes, such as Mmp12 and Gpnmb. Here, sets of molecules, but not a single molecule, identified by the unsupervised PCA, were found to be useful as the phase-specific biomarkers. Five mice were infected with TMEV intraperitoneally and hearvested their hearts on 4, 7, and 60 days post infection, respectively, for RNA isolation and hybridization on Affymetrix microarrays. As the control groups, age-matched uninfected mice were prepared.
