Abstract:Objective To explore the significance of coronavirus infection-related multiple organ dysfunction syndrome (MODS) following coronavirus disease 2019 (COVID-19) by bioinformatics prediction for molecular mechanism and intervention drugs. MethodsAfter the whole genome expression profile of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was obtained from the public database Gene Expression Omnibus (GEO), the Impute package of R language, Limma package and the Robust Rank Aggregation (RRA) algorithm were used respectively to standardize the data, screen differential expression genes (DEGs), and screen significant DEGs. Then epigenomic mechanism analysis was performed using the R language Clusterprofile package for GO function enrichment and KEGG pathway enrichment analysis. EpiMed (Epigenomic Precision Medicine Prediction platform) established earlier by us was used to screen potential intervention drugs. Results Bioinformatics analysis indicated that in the SARS-CoV-2 infected mice, lung injury was based on asthma signaling pathways, heart damage on viral myocarditis signaling pathways, kidney damage on proximal tubule bicarbonate recycle signaling pathways, liver injury on nonalcoholic fatty liver disease signaling pathways, and hematopoietic function damage on hematopoietic cell lineage signaling pathways. EpiMed platform screened out the drugs with potential intervention effect on SARS-CoV-2 infection-induced MODS, including TNF-1 inhibitors, polygonum cuspidatum, ritonavir, houttuynia cordata, nevirapine, patrinia, famciclovir, siduofovir, forsythia, interferon-α, chloroquine phosphate, remdesivir and abidol. Conclusion SARS-CoV-2 infection can cause MODS through organ-specific related pathways, and a series of potential intervention drugs are predicted based on these pathways, which need further in vivo and in vitro experiments and clinical validation. Our study helps to guide clinical and basic research on COVID-19 related MODS.
