In late December 2019, several cases of pneumonia of unknown etiology (COVID-19) were reported in Wuhan, Hubei province, China Based on clinical findings, blood tests and chest radiographs, this disease was diagnosed as a virus-associated pneumonia Sequence analysis revealed a novel coronavirus, called SARS-CoV-2 (formerly called 2019-nCoV), as the causative agent of pneumonia of unknown etiology So far, the SARS-CoV-2 infection continues to spread, and this virus poses a serious public health threat In this study, it was aimed to reveal potential miRNA targets for the regulation of SARS-CoV-2 host cell receptor ACE2 For the identification of potential miRNA targets for the ACE2 gene, TarBase v 8 (DIANA Tools), TargetScan, miRTarBase and miRDB miRNA-target prediction algorithms were used FANTOM5 CAGE was used for the cellular ontology analysis Expression levels of these miRNAs were determined using OncomiR Pan-Cancer miRNome Atlas The results suggest that members of miR-200 family of miRNAs, especially miR-200c-3p, are strong candidate targets for the regulation of ACE2 in respiratory system cells Consequently, the present study for the first time emphasizes potential use of miRNA-based therapeutics in the battle against SARS-CoV-2 infection and its deadly disease, COVID-19
