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.

IMPORTANCE The SARS-CoV-2 pandemic has emphasized the need to understand the mechanisms of severe lung inflammatory pathology caused by human deadly coronaviruses in order to design new antiviral therapies. Here, we identify miRNA-223-3p as a host miRNA involved in the regulation of lung inflammatory response mediated by envelope (E) protein during SARS-CoV infection. miRNAs downregulate the expression of cellular mRNAs and participate in complex networks of mRNA-miRNA interactions that regulate cellular processes. The inhibition of miRNA-223 in infected mice by intranasal administration of antisense RNAs led to changes in the expression of host factors involved in inflammation (cytokines, chemokines, and NLRP3 inflammasome) and in the resolution of lung edema ion transporter CFTR. These results confirmed the contribution of miRNA-223 to the regulation of SARS-CoV-induced pathogenic processes and support the therapeutic potential of inhibiting miRNAs during coronavirus infection using RNA interference approaches.

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:Objective: Parkinson's disease (PD) is part of a common type of neurodegenerative disease. AVE0991, a non-peptide analogue of Ang-(1-7), by which the progression of PD has been discovered to be ameliorated, but the specific mechanism whereby AVE0991 modulates the progression of PD remains unclear. Materials and Methods: During the study, the mice overexpressing of human α-syn(A53T) were established to simulate PD pathology, and we also constructed an in vitro model of mouse dopaminergic neurons overexpressing hα-syn(A53T). The [18F] FDG-PET/CT method was also employed to assess FDG uptake in human α-syn(A53T) overexpressing mice. Level of Lnc HOTAIRM1, miR-223-3p were detected via RT-qPCR. Flow cytometry was deployed to assay cell apoptosis. Results: AVE0991 improved behavior disorder and decreased α-syn expression in the substantia nigra in mice with Parkinson's disease. AVE0991 inhibited apoptosis of dopaminergic neurons overexpressing hα-syn(A53T) by LncRNA HOTAIRM1. MiR-223-3p binds to HOTAIRM1 as a ceRNA and directly targets α-syn. Conclusion: The angiotensin-(1–7) analogue AVE0991 targeted the HOTAIRM1/miR-223-3p axis to degrade α-synuclein in PD mice, and showed neuroprotection in vitro.

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.
