A large-scale proteomic identification of targets of cellular miR-197 downregulated by enterovirus A71

ABSTRACT: MicroRNAs are noncoding RNA species comprising 18–23 nucleotides that regulate host-virus interaction networks. Here, we showed that enterovirus A71 infection in human rhabdomyosarcoma (RD) involved miR-197 expression. miR-197 can regulate virus replication in the context of viral RNA synthesis via the transfection of its mimic into RD cells. We employed a mass spectrometry-based quantitative proteomic stable isotope labeling with amino acids in cell culture (SILAC) approach for the identification of miR-197 target genes by transfecting mimetic miR-197 into RD cells, and the differential expression of prospective target proteins was identified. A total of 1,822 genes were repeatedly and considerably downregulated in miR-197-transfected RD cells, 106 of which were predicted to have seed sites by TargetScan. Seven of the selected 8 genes potentially related to viral replication and immune response were confidently validated as direct miR-197 targets using a luciferase (untranslated region (3'-UTR)) reporter assay. The expression of three selected endogenous molecules (ITGAV, ETF1, and MAP2K1 (MEK1)) was significantly reduced when RD cells were transfected with an miR-197 mimic. Our results provide a database of miR-197 targets, which is potentially of interest in the area of viral pathogenesis and other research fields.

MicroRNAs are noncoding RNA species comprising 18-23 nucleotides that regulate host-virus interaction networks. Here, we show that enterovirus A71 infection in human rhabdomyosarcoma (RD) is regulated by miR-197 expression. Transfection of miR-197 mimic into RD cells inhibited virus replication by interfering with the viral RNA synthesis. We employed a combination of mass-spectrometry-based quantitative proteomics with the stable isotope labeling with amino acids in cell culture (SILAC) approach ...[more]

Project description:We previously put forward a multi-layer systems toxicology framework for in vitro assessment of e-liquids that is meant to complement the battery of classical assays for genotoxicity testing. The framework started with the first layer to screen e-liquids for their potential toxicity, followed by the second layer to investigate the toxicity-related mechanism of a selected e-liquid(s), and finally the third layer to evaluate the toxicity-related mechanism of the corresponding aerosol(s). In this work, we leveraged this framework to assess the biological impact of an e-liquid MESH™ “Classic Tobacco” and its aerosol in comparison with the impact of 3R4F reference cigarettes. In the first layer, we evaluated the cytotoxicity profile of the MESH Classic Tobacco liquid (containing humectants, nicotine, and flavors) and its Base liquid (containing humectant and nicotine only) in comparison with total particulate matter (TPM) of 3R4F cigarette smoke (CS). In the second layer, we explored changes in specific markers using high content screening assays to identify potential toxicity-related mechanisms of the MESH Classic Tobacco and Base liquids beyond cell viability compared with the 3R4F TPM-induced effects. In the third layer, we compared the biological impact of exposure to the MESH Classic Tobacco aerosol with CS using human organotypic buccal and small airway epithelial cultures. The results showed that the cytotoxicity profile of the MESH Classic Tobacco liquid was similar to the Base liquid but lower than the toxicity of 3R4F TPM at comparable nicotine concentrations. When compared with CS exposure, MESH Classic Tobacco aerosol exposure did not cause tissue damage and elicited lower changes in the global mRNA, global microRNA, and protein markers. The global mRNA changes following Classic Tobacco aerosol exposure indicated perturbations in processes related to cell fate, cell stress, and inflammatory response that were less than 20% of the perturbations following CS exposure. In the context of tobacco-harm reduction strategy, the framework is suitable to assess the potential reduced impact of EC aerosol relative to CS.
