Single-cell monitoring of dry mass and dry mass density reveals exocytosis of cellular dry contents in mitosis

• Curated by eLife

  Evaluation Summary:

  The authors measure dry mass and its density in growing and proliferating cells at high temporal resolution and with high precision. Using this method to study mitotic cells, the authors show that some cell types lose dry mass early in mitosis by a mechanism involving exocytosis. This work improves upon the authors' method to measure the mass of single cells and its thought-provoking conclusion is that dividing cells 'clean out' their contents to give the daughter cells a clean start.

  Evaluation Summary:

  Bao and colleagues present a chemical genetics study to identify novel compounds extending lifespan in C. elegans, and they proceed to investigate the mechanisms of action of their most potent compound. Based on the known target TRPV4 of the screening hit, the authors provide evidence for the involvement of a C. elegans homolog (osm-9) in the observed phenomenon, although this evidence is not completely conclusive. This study will be of interest to researchers working on drug discovery, repurposing and lead optimization in the context of ageing.

Tumor elimination by clustered microRNAs miR-306 and miR-79 via noncanonical activation of JNK signaling

• Curated by eLife

  Evaluation Summary:

  This paper is of interest for cancer biologists studying the role microRNAs in tumor growth. The work provides links between over-expression of microRNAs, downregulation of a ubiquitin ligase, inhibition of JNK and reduced tumor growth. Some of the data are properly controlled and analyzed. However, the key claims of the manuscript are not entirely supported by the data, and additional controls are needed.

  Evaluation Summary:

  Krasniewski and colleagues leveraged single-cell transcriptomics to identify subpopulations of macrophages in the skeletal muscle of aging male mice. They identify several new resident subpopulations of skeletal muscle macrophages, spanning a range of polarization states using novel markers, and they identify a shift in relative abundances of these subpopulations with age, leading to a functional shift in inflammatory marker expression and phagocytic capacity. The study overall is an interesting and timely investigation of skeletal muscle macrophage populations and transcriptomics in both healthy young and old mice, and should be a valuable resource for the inflammaging and muscle biology field.

Banp regulates DNA damage response and chromosome segregation during the cell cycle in zebrafish retina

• Curated by eLife

  Evaluation Summary:

  This study reports the phenotype of a zebrafish banp mutant that was identified in a screen for eye defects. Banp is known to regulate the transcription of a number of genes including those important in oncogenesis. In vivo function of Banp, especially in the context of normal development, remains to be better understood. The current study fills this knowledge gap and identifies the roles of banp during replication stress responses and mitosis. With somewhat more careful interpretation of the data and a clearer presentation of the results and their potential impact, this study will be of interest to scientists studying development, DNA damage responses and apoptosis.

  Evaluation Summary:

  The connection between double-strand break (DSB) formation and chromosome pairing/synapsis during meiosis is not fully understood. In this paper, the authors show that the formation of DSBs is regulated by the DNA damage response (DDR) machinery. The paper will be of interest to the broad meiosis and DDR communities. While the main conclusions of the manuscript appear to be well-supported by the data, some gaps are present and the manuscript would therefore benefit from additional (mostly minor) changes.
