  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.

• Curated by eLife

  Evaluation Summary:

  The manuscript presents a potentially interesting new method to study alternative splicing at the single-cell level in the mouse. With further testing and benchmarking, this method would be of interest to researchers working with single-cell data and/or interested in alternative splicing.

  Evaluation Summary:

  This manuscript reports for the first time associations between DNA methylation and gene expression in blood samples from 832 children. These associations are important for understanding the regulation of genes in the genome. The importance of this study is underlined by two surprising results: a minority of these associations are also observed in adult blood samples, and only half of the associations were with the nearest gene. These findings are critical for understanding the biological effects of DNA methylation changes caused by exposures and phenotypes.
