  Evaluation Summary:

  This paper aims to identify enhancers controlling human cardiovascular development. The authors identified a set of highly conserved regulatory elements bioinformatically and tested one of these in vivo, in medaka, and in vitro, in hESC differentiated into endothelial cells. They find deletion of this enhancer had no significant effect on the expression of FLT1 mRNA in the human cell line or on the formation of tube formation. However, deletion of the orthologous enhancer in medaka showed phenotypic effects in blood clot formation. Together, the data provide insights into the function of an enhancer controlling FLT1. This manuscript will be of interest to scientists interested in gene regulation, vascular biology and developmental biology.

  Evaluation Summary:

  This manuscript describes an exciting new approach for tagging and isolation of unique neuronal subpopulations, which has traditionally been challenging without the incorporation of expensive and time consuming transgenic animal colonies. While the manuscript highlights a specific test case of this technology with neurons expressing Parvalbumin, in theory this method could be applied to any neuronal or even non-neuronal cell type. Further, this approach could be applied to other model organisms for which transgenic technologies are limited, thereby facilitating research in other species.

  Evaluation Summary:

  Neurons use activity-responsive gene programs to shape cell specific identity and respond appropriately to environmental stimuli. By combining elegant protein degradation and cell-specific knockout approaches with transcriptional profiling and chromatin structure analysis, this manuscript delineates the contributions of cohesin (a key protein responsible for genome structure and organization), in activity-dependent gene expression programs and stimulus-dependent chromatin reorganization. These results demonstrate that cohesin is required for full expression of key genes required for the maturation and activation of cortical excitatory neurons, and reveal a tight correlation between cohesin effects and the genomic distance of higher order chromatin loops.

  Evaluation Summary:

  This paper will be of interest to scientists studying metabolism and those interested in the evolution of genomic imprinting. The authors show how parent-of-origin effects in crosses between inbred strains of mice can arise from epistasis between imprinted and unimprinted loci. They consider scenarios for the interactions of imprinted and unimprinted genes in adipocytes.
