  Evaluation Summary:

  This paper is of interest to researchers studying muscle function in the nematode C. elegans and to researchers interested in muscle aging in humans. The work documents the importance of C. elegans alh-6, which encodes a proline catabolic gene, in limiting muscle stress and maintaining locomotory function in aging nematodes. Further work implicates GWAS SNPs in the human homolog ALDH4A1 as potential determinants of specific muscle decline indicators. The suggestion of a conserved role for ALH-6 in aging humans could underlie establishment of a useful biomarker for older age muscle-associated health. However, while the work expands on and reinforces findings in C. elegans, it does not yet rigorously demonstrate a role for ALDH4A1 in muscle function in aging humans.

• Curated by eLife

  Evaluation Summary:

  The study investigates obesity and adipose distribution on hematopoiesis. It shows that genetically determined adiposity plays a previously underappreciated role in determining blood cell formation and function. The authors performed all the relevant and available MR analyses in the "toolbox". The results support the conclusions. The study will help understand the pathogenesis for clonal hematopoiesis.

Application of ATAC-Seq for genome-wide analysis of the chromatin state at single myofiber resolution

  Evaluation Summary:

  In this paper, Sahinyan and colleagues developed a method for analyzing chromatin accessibility in single murine myofibers. This goal was achieved by adapting the previously published OMNI-ATAC protocol to the specific properties of the myofiber environment. To demonstrate the validity of this method, they isolated myofibers from uninjured and regenerating murine EDL muscles dissected from wild type animals. In a second experiment, this method was applied to isolate myofibers from mdx mice, a model of Duchenne Muscular Dystrophy. The resulting datasets were further compared to the one generated from purified muscle stem cells.

Mendelian randomization suggests a bidirectional, causal relationship between physical inactivity and adiposity

  Evaluation Summary:

  The manuscript by Carrasquilla and colleagues applied Mendelian Randomization (MR) techniques to study causal relationship of physical activity and obesity. Their results support the causal effects of physical activity on obesity, and bi-directional causal effects of sedentary time and obesity. One strength of this work is the use of CAUSE, a recently developed MR method that is robust to common violations of MR assumptions. The conclusion reached could potentially have a large impact on an important public health problem.

  Evaluation Summary:

  Oligogenic inheritance is likely to be an important mode of disease risk for many male infertility traits, but few validated examples exist. This clear documentation of oligogenic effects on mouse sperm is significant for both the sperm abnormality field and for the broader male infertility community.

  Evaluation Summary:

  This paper presents results showing the temporal relationships between deletion of a resistance gene, introduction of antibiotic, and cell growth that are intriguing and novel. It will be of interest to researchers studying heterogeneity in antibiotic tolerance and the origins of drug resistance.
