  This valuable study offers insights into the role of Leiomodin-1 (LMOD1) in muscle stem cell biology, advancing our understanding of myogenic differentiation and indicating LMOD1 as a regulator of muscle regeneration, aging, and exercise adaptation. The integration of in vitro and in vivo approaches, complemented by proteomic and imaging methodologies, is solid. However, certain aspects require further attention to improve the clarity, impact, and overall significance of the work, particularly in substantiating the in vivo relevance. This work will provide a starting point that will be of value to medical biologists and biochemists working on LMOD and its variants in muscle biology.

  This valuable paper reports machine learning-based image analysis pipelines for the automated segmentation of micronuclei and the detection and sorting of micronuclei-containing cells. These are powerful new tools for researchers who study micronuclei and their physiologic consequences. The analysis of the new tools and their benchmarking is rigorous and convincing; applications and remaining limitations are well explained in the paper.

  This fundamental research conducted a molecular comparison between smooth muscle cells and adjacent fibroblast cells within lung blood vessels affected by pulmonary arterial hypertension. The study identified distinct disease-related states in each cell type and provided deeper insights into their interactions and communication. While certain conclusions should be interpreted with caution due to inherent methodological limitations, the study's findings remain convincing and robust. This is supported by the use of advanced and complementary techniques, as well as the rare isolation of diseased lung blood vessel cells from the same donor, enabling direct comparison.

• Curated by eLife

  eLife Assessment

  The study by Chen and Phillips provides evidence for a dynamic switch in the small RNA repertoire of the Argonaute protein NRDE-3 during embryogenesis in C. elegans. The work is supported by convincing experimental data, shedding light on RNA regulation during development. While the functional relevance of this process warrants further investigation, this study provides valuable insights into small RNA pathways with broader implications for developmental biology and gene regulation in other systems.

  This study provides valuable information on the single nucleus RNA sequencing transcriptome, pathways, and cell types in pig skeletal muscle in response to conjugated linoleic acid (CLA) supplementation. Based on the comprehensive data analyses, the data are considered compelling and provide new insight into the mechanisms underlying intramuscular fat deposition and muscle fiber remodeling. The study contributes significantly to the understanding of nutritional strategies for fat infiltration in pig muscle.

  This valuable study provides convincing evidence that specific proteins on the surface of cancer cells undergo a particular form of recycling and are redirected toward the cell-cell contact with T cells, a type of immune cell. However, the characterization of the consequences of T cell activation resulting from perturbing the recycling pathway is incomplete. Furthermore, relevant literature has not been sufficiently cited.
