  eLife assessment

  This valuable work explores how transcription factors regulate transcription through cooperative binding to enhancers. Through experiments and modeling, the authors show convincingly that the cooperativity of transcription factor binding regulates transcriptional bursting and the extent of the amount of time that the target promoter remains in an active state.

  eLife assessment

  This important study reports how swallowtail butterflies pattern structures composed of chitin at the nanometer scale to produce structural colors. The work uses state-of-the-art microscopy techniques to convincingly show that F-actin is utilized in these butterflies in a novel way to produce structure, paving the way for further studies on growth regulation leading to precise ultrastructures and structural colors.

  This current study provides a new model of lung agenesis to explore the generation of the ability of blastocyst complementation to generate an entire organ. These studies will provide new avenues for organ bioengineering and additional insight into early contribution of mesoendoderm to lung development.

  This study provides a clearly presented and thoughtfully analyzed single cell-resolution dataset of gene expression in wildtype and mutant zebrafish skin. These data are used by the authors to develop and test hypotheses about cell lineage relationships and signaling interactions between cell types in the skin, allowing them to identify roles for several signaling pathways and the hypodermis in scale and pigment cell development. These findings constitute a fundamental contribution to the field, and the rigor of the analyses make this manuscript compelling.

  eLife assessment:

  This study presents valuable findings on the impact of C-natriuretic peptide (CNP) treatment in vivo on the fertility of aged mice. Solid data indicate CNP induces the cAMP-PKA pathway, causing reduced recruitment of Parkin protein to mitochondria in oocytes, resulting in reduced mitophagy, which may be significant for increased mitochondrial bioenergetics and improved cytoplasmic and nuclear maturation. The authors make additional claims regarding the mechanisms by which CNP impacts oocyte quality in vivo for which the evidence is inconclusive. This work will be of interest to reproductive biologists and clinical infertility specialists.
