      This manuscript reports important findings that the methyltransferase METTL3 is involved in the repair of abasic sites and uracil in DNA, mediating resistance to floxuridine-driven cytotoxicity. The presented evidence is conclusive for the involvement of m6A in DNA involving single cell imaging and mass spectrometry data. The authors present convincing evidence that the m6A signal does not result from bacterial contamination or RNA.

      This short manuscript uses mutation counts in phylogenies of millions of SARS-CoV-2 genomes to show that mutation rates systematically differ between regions that are paired or unpaired in the predicted RNA secondary structure of the viral genome. Such an effect of pairing state is not unexpected, but its systematic demonstration using millions of viral genomes is valuable and convincing.

      In this manuscript, the authors describe a new AlphaFold2 pipeline called PabFold that can represent a useful tool for identifying linear antibody epitopes (B-cell epitopes) for different antigens. This information can be used in the selection of different reagents in competitive ELISA assays which can save time and reduce costs. Because several questions about the work remain, the study is currently incomplete.

      eLife Assessment

      This is an important study providing compelling evidence that the Mediator kinase module mediates an elevated inflammatory response, manifested by heightened cytokine levels, associated with Downs syndrome (DS) via transcriptional changes impacting cell signaling and metabolism that involve mobilization of nuclear receptors by altered lipid metabolites, which has significance for the treatment of DS and other chronic inflammatory conditions. Particular strengths of the study include the combined experimental approaches of transcriptomics, untargeted metabolomics and cytokine screens and the use of sibling matched cell lines (trisomy 21 vs disomy 21) from various donors. Evidence is also provided implicating the Mediator kinase module in controlling mRNA splicing and mitochondrial function that should stimulate new research to elucidate the mechanistic bases for these novel functions.

      This study presents a new quantitative method, CROWN-seq, to map the cap-adjacent RNA modification N6,2'-O-dimethyladenosine (m6Am) with single nucleotide resolution. Using thoughtful controls and well-validated reagents, the authors provide compelling evidence that the method is reliable and reproducible. Additionally, the study provides important evidence that m6Am may increase transcription in modified mRNAs. However, the data only demonstrates a correlation between m6Am and transcriptional regulation rather than causality. Overall, this study is poised to advance m6Am research, being of broad interest to the RNA biology and gene regulation fields.

      eLife Assessment

      This study provides useful in vitro evidence to support a mechanism whereby dyslipidemia could accelerate renal functional decline through the activation of the AT1R/LOX1 complex by oxLDL and AngII. As such, it improves the knowledge regarding the complex interplay between dyslipidemia and renal disease and provides a solid basis for the discovery of novel therapeutic strategies for patients with lipid disorders. The methods, data, and analyses partly support the presented findings, although the observed variability and need for further in vivo validation require additional research in this key area.

      This valuable study shows previously unappreciated binding of the eukaryotic translation initiation factor 3 (eIF3) to the poly(A) tail proximal portion of 3' untranslated regions (UTRs) of mRNAs that are efficiently translated in neuronal progenitors. The authors' conclusions are supported by solid experimental evidence which is based on several orthogonal systems biology approaches. This article is of considerable interest to the broad spectrum of biomedical researchers interested in studying post-transcriptional regulation of gene expression.

      eLife Assessment

      This study presents important analyses of the impacts of microexon deletions and loss-of-function in microexon regulators on zebrafish neurite outgrowth and gene expression, as well as adult and larval behavior. While microexons have been mapped in many genes several years ago, information on their functions - in particular with regard to individual gene isoforms - is limited. The authors provide convincing evidence that individual microexon deletions, only in a few cases, produce subtle cellular and behavioural phenotypes, while transcriptomic analysis reveals gene expression alterations that are suggestive of compensatory mechanisms that buffer against microexon disruption.
