Clinical manifests vary from no symptoms, upper and lower respiratory tract infections, and even severe acute respiratory distress syndrome and multiple organs failure. Recently, three of new beta-coronaviruses have emerged to cause serious and widespread illness and death, such as the Severe Acute Respiratory Syndrome Coronaviruses (SARS-CoV), Middle East Respiratory Syndrome Coronaviruses (MERS-CoV), and 2019-nCoV (the causative pathogen of Coronavirus Disease 2019 (COVID-19). The COVID-19 is continuing to spread globally. However, the detailed molecular mechanisms have not yet been fully clarified. Since the similarity of the pathological features among 2019-nCoV, SARS-CoV and MERS-CoV, we could speculate the biological features of current COVID-19 by researching those of MERS-CoV and SARS-CoV. Therefore, we analyzed expression levels of miRNA and mRNA profiles of MERS-CoV, SARS-CoV and 2019-nCoV from five public GEO datasets (Table S1). As a result, we found 16 miRNAs potentially target a group of hub genes clustering together to tune the immune response. Notably, viral RNAs have the ability to sponge miR-500a-5p and miR-501-5p, indicating viral RNAs sequestering these two miRNAs to trigger genes expression and contribute to pathogenesis. We hope this study will pave the way to better understand 2019-nCoV pathogenesis and develop the innovative therapeutics.展开更多
