Recent studies show that SARS-CoV-2 infection changes the host cell m6A methylome in vitro, promoting differential expression of host genes [13], and in vivo, altering m6A modification levels in lymphocytes from peripheral blood samples by increased expression of the m6A methyltransferase RNA-binding motif protein 15 (RBM15) [17] or decreased expression of METTL3 in epithelial cells of bronchoalveolar lavage fluid of COVID-19 patients [13]. This evidence concerns the gene RBM15 and COVID-19.
