Although two nasopharyngeal microbiome datasets contained both patients with COVID-19 and Non-COVID-19 controls, the statistical power was limited by the small sample size (Liu et al.36) and a large portion of sequencing reads from another dataset (PRJNA74398137) were from the human host. METTL3-mediated m6A modification is required for cerebellar development. 11, pp. Although the majority of MAGs we reconstructed in this study have high quality, future investigations aiming for recovering the complete genome of microbes will further enhance our understanding of the interaction between human microbiome and SARS-CoV-2 infection76,77. 37, 246258 (2014).

Ke, S., Weiss, S.T. Zc3h13 Regulates Nuclear RNA m6A Methylation and Mouse Embryonic Stem Cell Self-Renewal. Consecutive cell divisions may accompany with telomere shortening leading to replicative senescence [23]. As the lifespan curve (Figures 2(a), 2(b), and 2(c)) shows, a long-term (30d) treatment approximately doubled the days before replicative senescence and the maximum cumulative population doublings. The ongoing pandemic of coronavirus disease 2019 (COVID-19), a respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has infected billions of people world-wide. Due to the inherent differences (e.g., age, diet, and genetic background) across the different datasets, our goal was not targeted comparisons across datasets. Front. In the dataset from Yeoh et al.19, the gut microbiome samples from those patients with COVID-19 were collected before and after their nasopharyngeal aspirates or swabs tested negative for SARS-CoV-2 via RT-qPCR. 11, e643 (2021).

Biol. Therefore, the prolonged presence of large amounts of fecal SARS-CoV-2 RNA virus is unlikely to be explained by the swallowing of virus particles replicated in the throat but rather suggests enteric infection with SARS-CoV-2.
