  Evaluation Summary:

  The paper describes improvement in muscle phenotype of a congenital myopathy mouse model by a combined treatment with pharmacological inhibitors of Class IIa histone deacetylases and DNA methylases. The paper demonstrates in principle that there are treatment avenues to pursue but their application could be limited as phenotypic rescue appears to be restricted to particular muscle fiber types.

  Evaluation Summary

  This paper will be of interest to readers in the fields of exercise physiology, muscle biology and energy metabolism. The authors provide a proteomic resource where changes in the skeletal muscle proteome and acetyl-proteome have been assessed following the increasingly popular exercise intervention of high intensity interval training (HIIT). The adaptive responses reported provide new insight into the metabolic, contractile and transcriptional changes in muscle, and may represent an excellent resource for stimulating future focussed molecular studies in the field.

  Evaluation Summary:

  This manuscript uses primary placental units and villous explants to examine the placental metabolism of vitamin D and effects of vitamin D on placental gene expression. The studies demonstrate that the placenta actively transports 25D, such that the fetal levels are dependent on placental function rather than simple diffusion from the maternal circulation. Furthermore, they demonstrate actions of vitamin D on placental gene expression. This paper should be of interest to cell biologists and obstetricians/gynaecologists studying the role of the placenta in fetal growth and development.

  Evaluation Summary:

  Huang et al have identified SOX4 as a key regulatory factor that controls prolactin and FOXO1 transcription factor which in turn regulate decidualization, an important process in embryo development. Further, they have identified that SOX4 also regulates progesterone receptor and dysregulated SOX4-progesterone and ubiquitin ligase HERC4can lead to embryo implantation failure thus explaining the molecular basis of recurrent implantation failure in humans. Overall the study is interesting and the data are very strong. Some concerns noted were the use of immortalized stromal cells, and incomplete nature of studies with human endometrial stroll cells from endometriosis patients, and lack of sufficient discussion in some parts of the text, and whether specific progesterone isofoms are involved downstream of SOX4.

• Curated by eLife

  Evaluation Summary:

  This study investigates the important question of how vasopressin neurons, which are critical for fluid balance, are rapidly activated or inhibited when mice begin to eat or drink. The study presents useful anatomic data on connectivity between these neurons and other structures and tests a broad range of possible inputs that could mediate these effects. The conclusions are largely supported by the data.

  Evaluation Summary:

  The manuscript by Lee and co-workers describes the development of 21 unique transgenic mouse lines that express optogenetic sensors and effectors in a cell lineage-specific fashion. The knock-in approach allows the sensors and effectors to be rapidly combined or moved to different backgrounds, such as genetic disease models. Such manipulations are often impractical when using a Cre-based system. This constitutes a vital advantage for many studies. The new mice described here will be very powerful tools to study physiology and alteration in disease models.

  Evaluation Summary:

  This is a rigorous and clearly written paper that provides quantitative data for the scope of intracellular signalling by ASIC channels. These channels are involved in pain signalling and other processes, and apparently can couple to intracellular pathways independent of ion flow. Here the authors measure the movements of the unstructured intracellular parts of ASIC using fluorescence spectroscopy coupled to functional measurements.
