  Evaluation Summary:

  The authors aim to understand how certain transposable elements escape chromatin-based silencing. Focusing on variably methylated copies of IAP (VM-IAPs) in the mouse, the authors show that elements that can escape silencing share sequence variations that alter KRAB zinc finger protein (KZFP) binding and KAP1 recruitment, proximity to expressed genes and high CpG content. Analysis of human elements in human KZFP-free mouse cells recapitulates some of these observations. The authors propose that ZF-CxxxC proteins play a role in establishing permissive chromatin at transposable elements that harbor high CpG content and weak KZFP binding. The data are mostly correlative and open the path for further mechanistic analyses. The paper is of interest to readers in the field of epigenetics, genome biology and transposable elements.

  Evaluation Summary:

  This manuscript introduces a novel method for the monitoring of immune dynamics from blood, based on a measurement of the burden of cell-free DNA derived from seven key immune cell types in blood. The authors demonstrate the possibility to quantify the specific amounts of cell-free DNA by assaying cell-type specific CpG methylation marks via a targeted DNA sequencing assay. Assays of specific immune cell counts in blood are commonplace in modern diagnostic medicine. Rather than counting cells, the assay reported in this manuscript measures the burden of DNA released by dying immune cells, and this new assay may provide information about the immune system beyond what is possible with mere cell counting. The authors test their assay in three different settings (vaccination, inflammation and cancer), and provide significant support for the utility of their assay for immune monitoring in health and disease.

  Evaluation Summary:

  The authors investigate the contribution of a CTCF binding site located 3' of the beta-globin locus to the relative expression of the genes within the cluster. Their results serve to further clarify a longstanding model for how relatively high levels of fetal beta-globin are observed in some individuals harboring a deletion of this region, and contribute to existing models of the function of CTCF binding sites in genome organization.

  Evaluation Summary:

  The Codetta method developed by Shulgina and Eddy is a powerful approach for inferring codon reassignment by comparative analysis of bacterial and archaeal genomes. Given the rapid advances of genomic and metagenomic sequencing, this will be an important tool for elucidating the genetic codes employed by prokaryotes.
