  This is a fundamental resource of snRNA-seq and and chromatin accessibility data from human aortic endothelial cells (ECs), treated with relevant perturbations such as IL1b, TGFB2, or si-EGR. The authors show that ECs can be categorized by distinct subpopulations of differing plasticity. The support for the existence of these subpopulations is compelling, supported also by three publicly available scRNA-seq datasets, and differential enrichment of coronary artery disease associated SNPs in open chromatin in these subpopulations.

  The findings in the manuscript are important and the strength of evidences from the genomic analyses is convincing. However, the evidence for the existence of functional MER21B/C remnants in mice, as well as for the imprinting status of Zdbf2 in rabbits and non-human primates was viewed as mainly correlative and incomplete. This manuscript will be of interest to developmental biologists and those working on possible novel mechanisms of gene regulation.

  Editors Assessment:

  The snake pipefish, Entelurus aequoreus, is a species of fish that dwells in open seagrass habitats in the northern Atlantic. As a pipefish, it is a member of the Syngnathidae family of fish which also includes seahorses and seadragons. In recent years it has expanded its population size and range into arctic waters. To better understand these demographic changes genomic data is useful, and to address this a high-quality reference genome has been produced. Building on a previous short-read reference, a near chromosome-scale genome assembly for the snake pipefish was assembled using PacBio CLR and Hi-C reads. After revisions the authors provided more details on the assembly metrics, the final assembly has a length of 1.6 Gbp, with scaffold and contig N50s of 62.3 Mbp and 45.0 Mbp respectively. Demographic inference analysis of the snake pipefish genome using this data enables tracing of population changes over the past 1 million years, and this reference will allow further analyses and studies relating these to changes in climate.

The genomic landscape of transposable elements in yeast hybrids is shaped by structural variation and genotype-specific modulation of transposition rate

  This valuable study advances our understanding of the forces that shape the genomic landscape of transposable elements. By exploiting both long-read sequencing of mutation accumulation lines and in vivo transposition assays, the authors offer compelling evidence that structural variation rather than transposition largely shapes transposable element copy number evolution in budding yeast. The work will be of interest to the transposable element and genome evolution communities.

  This important paper uses a genome-wide, massively parallel reporter assay to determine how CpG methylation affects regulatory sequences that control the expression of human genes. The authors provide compelling evidence that methylation not only influences baseline activity of regulatory sequences but also the magnitude of acute responses to environmental stimuli. The findings are of broad interest, and the extensive data set will likely become a key resource for the community.

  CCL2 is a chemokine known to have relevant immune cell chemoattractant properties, and it is believed to play a role in several chronic inflammatory diseases. The RNA-binding protein HuR controls the stability and translation of CCL2 mRNA. This paper presents solid evidence that a relatively common genetic variant tied to several disease phenotypes affects the interaction between the mRNA of CCL2 and the RNA-binding protein HuR. As CCL2 is believed to be relevant for leukocyte migration in various conditions, including chronic inflammation and cancer, this is an important finding that may be relevant to a broad audience.
