Project description:Severe acute respiratory syndrome coronavirus (SARS-CoV) and the closely related SARS-CoV-2 are emergent highly pathogenic human respiratory viruses causing acute lethal disease associated with lung damage and dysregulated inflammatory responses. SARS-CoV envelope protein (E) is a virulence factor involved in the activation of various inflammatory pathways. Here, we study the contribution of host miRNAs to the virulence mediated by E protein. Small RNAseq analysis of infected mouse lungs identified miRNA-223 as a potential regulator of pulmonary inflammation, since it was significantly increased in SARS-CoV-WT virulent infection as compared to the attenuated SARS-CoV-∆E infection. In vivo inhibition of miRNA-223-3p increased mRNA levels of pro-inflammatory cytokines and NLRP3 inflammasome, suggesting that during lung infection, miRNA-223 might contribute to restrict an excessive inflammatory response. Interestingly, miRNA-223-3p inhibition also increased the levels of the CFTR transporter, which is involved in edema resolution and was significantly downregulated in the lungs of mice infected with the virulent SARS-CoV-WT virus. At the histopathological level, a decrease in the pulmonary edema was observed when miR-223-3p was inhibited, suggesting that miRNA-223-3p was involved in the regulation of the SARS-CoV-induced inflammatory pathology. These results indicate that miRNA-223 participates in the regulation of E protein mediated- inflammatory response during SARS-CoV infection by targeting different host mRNAs involved in the pulmonary inflammation and identify miRNA-223 as a potential therapeutic target in SARS-CoV infection.

Project description:Severe acute respiratory syndrome coronavirus (SARS-CoV) causes lethal disease in humans, with viral E protein promoting the exacerbated inflammatory response. By deep sequencing RNAs from the lungs of infected mice, we have addressed the relevance of small, non-coding RNAs in SARS-CoV pathology. Host microRNAs (miRNAs) expressed during infection by a virulent virus encoding the E protein were significantly enriched for cytokine-mediated inflammatory pathways when compared with attenuated SARS-CoV-∆E, suggesting contribution of miRNAs to E protein-induced inflammation. The discovery of three 18-22 nt small viral RNAs (svRNAs) derived from the nsp3 and N genomic regions of SARS-CoV in mouse lung and cell cultures is also described. Depletion of these svRNAs significantly reduced viral titers and genomic RNA levels, indicating their positive contribution to virus growth. Remarkably, svRNA-N antagomirs significantly reduced in vivo lung pathology and pro-inflammatory cytokine expression, indicating that svRNAs contribute to SARS-CoV pathogenesis and highlighting the potential of these antagomirs as antivirals.

Project description:Non-thermal plasma, a partially ionized gas, holds significant potential for clinical applications, including wound healing support, oral therapies, and anti-tumour treatments. While its applications shown promising outcomes, the underlying molecular mechanisms remain incompletely understood. We thus applied non-thermal plasma to mouse auricular skin and conducted non-coding RNA sequencing, as well as single-cell blood sequencing. In a time-series analysis (5 time points spanning 2 hours), we compared the expression of microRNAs in the plasma-treated left ears to the unexposed right ears of the same mice as well as to the ears of unexposed control mice. Our findings indicate specific effects in the treated ears for a set of five miRNAs: mmu-miR-144-5p, mmu-miR-144-3p, mmu-miR-142a-5p, mmu-miR-223-3p, and mmu-miR-451a. Interestingly, miR-223-3p also exhibited an increase over time in the right non-treated ear of the exposed mice, suggesting systemic effects. Notably, this miRNA, along with mmu-miR-142a-5p and mmu-miR-144-3p, regulates genes and pathways associated with wound healing and tissue regeneration (namely ErbB, FoxO, Hippo, and PI3K-Akt signalling). This co-regulation is particularly remarkable considering the significant seed dissimilarities among the miRNAs. Finally, single blood cell sequencing revealed the downregulation of 12 from 15 target genes in B-cells, Cd4+ and Cd8+ T-cells. Collectively, our data provide evidence for a systemic effect of non-thermal plasma.

Project description:Objective: Emerging evidence suggested that brain angiotensin-(1-7) (Ang-(1-7)) deficiency contributed to the pathogenesis of Alzheimer’s disease (AD). Meanwhile, our previous studies revealed that restoration of brain Ang-(1-7) levels provided neuroprotection by inhibition of inflammatory responses during AD progress. However, the potential molecular mechanisms by which Ang-(1-7) modulates neuroinflammation remain unclear. Materials and Methods: APP/PS1 mice were injected intraperitoneally with AVE0991 (a nonpeptide analogue of Ang-(1-7)) once a day for 30 consecutive days. Cognitive functions, neuronal and synaptic integrity, and inflammation-related markers were assessed. Since astrocytes played a crucial role in AD-related neuroinflammation whilst long noncoding RNAs (lncRNAs) were reported to participate in modulating inflammatory responses, astrocytes of APP/PS1 mice were then isolated for high-throughput lncRNA sequencing to identify the most differentially expressed lncRNA following AVE0991 treatment. Afterward, the downstream pathway of this lncRNA in the anti-inflammatory action of AVE0991 were investigated using primary astrocytes. Results: The protection of AVE0991 against cognitive impairment and neuronal and synaptic damage in APP/PS1 mice was confirmed. For the first time, we demonstrated that AVE0991 suppressed astrocytic NLRP3 inflammasome-mediated neuroinflammation via a lncRNA SNHG14-dependent manner. SNHG14 acted as a sponge of miR-223-3p while NLRP3 represented a direct target of miR-223-3p in astrocytes. In addition, miR-223-3p participated in the AVE0991-induced suppression of astrocytic NLRP3 inflammasome. Conclusion: These results suggest that AVE0991 inhibits astrocyte-mediated neuroinflammation via SNHG14/miR-223-3p/NLRP3 pathway. Moreover, these results reveal the underlying mechanisms by which Ang-(1-7) inhibits neuroinflammation under AD condition and uncovers the potential of its nonpeptide analogue AVE0991 in AD treatment.

Project description:Severe acute respiratory syndrome coronavirus (SARS-CoV) causes lethal disease in humans, which is characterized by exacerbated inflammatory response and extensive lung pathology. To address the relevance of small non-coding RNAs in SARS-CoV pathology, we deep sequenced RNAs from the lungs of infected mice and discovered three 18–22 nt small viral RNAs (svRNAs). The three svRNAs were derived from the nsp3 (svRNA-nsp3.1 and -nsp3.2) and N (svRNA-N) genomic regions of SARS-CoV. Biogenesis of CoV svRNAs was RNase III, cell type, and host species independent, but it was dependent on the extent of viral replication. Antagomir-mediated inhibition of svRNA-N significantly reduced in vivo lung pathology and pro-inflammatory cytokine expression. Taken together, these data indicate that svRNAs contribute to SARS-CoV pathogenesis and highlight the potential of svRNA-N antagomirs as antivirals.

Project description:MicroRNAs (miRNAs) have been shown to play important roles in the pathogenesis of viral infections, but little is known about the miRNA alternations associated with SARS-CoV-2 infection. Here, we performed high throughout sequencing to detect miRNAs in the plasma samples collected from 61 healthy controls, 16 asymptomatic individuals and 100 symptomatic COVID-19 patients. In total, we identified 2,336 known miRNAs and 361 novel miRNAs, including 75 differentially expressed miRNAs with p value<0.05 between various groups. We also found a number of miRNAs that were associated with various clinical presentations and viral persistence of COVID-19, such as hsa-miR-370-3p, hsa-miR-146a-3p, hsa-miR-885-5p, hsa-miR-214-3p and hsa-miR-10b-5p. Further analysis of the target genes, gene ontology and KEGG pathways revealed a panel of miRNAs that were linked to immune responses, viral infections, inflammation and apoptosis. Our findings may help understand the contribution of miRNAs to the pathogenesis of COVID-19 and identify potential biomarkers and molecular targets for the diagnosis and treatment of SARS-CoV-2 infection.

Project description:We used a multi-omics approach combining transcriptomics, proteomics and metabolomics to study the impact of over-expression and inhibition of the microRNA miR-223, a pleiotropic regulator of metabolic-related disease, in the RAW monocyte-macrophage cell line. We analyzed the levels of proteins, mRNAs, and metabolites in order to identify genes involved in miR-223 regulation, to determine candidate disease biomarkers and potential therapeutic targets. We observed that both up- and down-regulation of miR-223 induced profound changes in the mRNA, protein and metabolite profiles in RAW cells. Microarray-based transcriptomics evidenced a change in 120 genes that were linked predominantly to histone acetylation, bone remodeling and RNA regulation. In addition, 30 out the 120 genes encoded long noncoding RNAs. The nanoLC-MS/MS revealed that 52 proteins were significantly altered when comparing scramble, pre- and anti-miR-223 treatments. Sixteen out of the mRNAs coding these proteins genes are predicted to have binding sites for miR-223. CARM-1, Ube2g2, Cactin and Ndufaf4 were confirmed to be miR-223 targets by western blotting. Analyses using Gene Ontology annotations evidenced association with cell death, splicing and stability of mRNAs, bone remodeling and cell metabolism. miR-223 alteration changed the expression of CARM-1, Ube2g2, Cactin and Ndufaf4 during osteoclastogenesis and macrophage, indicating that these genes are potential biomarkers of these processes. The most important discriminant metabolites found in the metabolomics study were found to be hydrophilic amino acids, carboxylic acids linked to metabolism and pyrimidine nucleotides, indicating that changes in miR-223 expression alter the metabolic profile of cells, and may affect their apoptotic and proliferative state.
