eLife Assessment

This is a useful study investigating the role of peristalsis in the elongation of the gut, using the chick ceca as a model. The work employs optogenetics together with embryological approaches to establish links between peristaltic muscle contractions and downstream cell behaviors that lead to tube elongation. However, the work is somewhat incomplete, limited in mechanistic insights that would extend beyond prior work in the literature, which has already suggested a role for smooth muscle contractility in avian gut elongation.

eLife Assessment

This is an important study that comprehensively determines the consequences of DNMT3A mutations on human neuronal development in culture. The data derived from multiple different mutations in iPSC and hESC derived neurons and organoids are convincing and well controlled. This work will be of interest to researchers who study chromatin mechanisms of brain development and to those interested in DMNT3A mutations in Tatton-Brown-Rahman Syndrome.

eLife Assessment

This valuable study builds a novel auditory-motor paradigm to investigate how the brain learns associations between movements and their auditory consequences. Solid evidence is provided for early ERPs (50-100 ms latency) reflecting violations of established key-pitch mappings. The study is of potential interest to researchers studying audition, sensorimotor integration, or predictive coding, but some statistical analyses, however, could still be improved.

eLife Assessment

This useful study asked whether the behaviour of motor units from a hand muscle changed across the two mechanical actions it performs. The authors used high-density intramuscular electrodes to record the activity of several motor units and reported changes in motor unit recruitment order across tasks that were not dependent on motor unit properties, suggesting differential spinal contributions to the two actions. However, the evidence supporting their main claims is incomplete, and some of the conclusions are based on unsubstantiated assumptions: the authors should correct several key analyses and temper claims that are not directly backed up by their data.

eLife Assessment

The authors make the valuable observation that directional memory during epithelial cell migration is enhanced in collective contexts compared to single-cell migration. While there is solid evidence for some parts of the work, the evidence linking directional memory to adherens junctions and vinculin dimerization remains limited. Key issues are that the Y1065E mutant may affect vinculin beyond its ability to dimerize, and focal adhesions were not directly compared across migration contexts.

eLife Assessment

The study provides valuable findings suggesting that modifying the donor's diet improves the effectiveness of fecal transplant therapies for liver disease. Although the reported results are of value, the evidence supporting the overall conclusions is incomplete. In particular, causal inferences regarding the effects of microbiota composition, as well as caproic acid signaling on the phenotypes studied, need further confirmation.

eLife Assessment

This study provides valuable evidence that glycogen phosphorylase is unlikely to represent an effective insecticidal target in Plutella xylostella and that diflubenzuron does not directly inhibit this enzyme. The combination of biochemical, molecular and physiological approaches provides convincing data to support these conclusions, although the proposed metabolic compensation mechanism is supported primarily by indirect evidence and would benefit from direct demonstration.

eLife Assessment

This manuscript proposes a valuable idea on how cortical networks may learn a helpful representation of sensory stimuli. The model implementing this idea is tested in multiple experimental paradigms. However, the evidence remains incomplete as to whether the method supports both invariance and equivariance and whether it can estimate the dynamics of the moving object.

eLife Assessment

This valuable study examines how the rodent prelimbic cortex represents learned and generalized threat over time and identifies distinct stable and dynamic neuronal populations that contribute to these representations. The evidence is convincing, supported by longitudinal calcium imaging, appropriate control groups, and sophisticated analyses showing that the relevant neural signals cannot be explained simply by freezing behavior. The work provides a conceptual framework for understanding how stable threat-related representations supporting memory generalization and discrimination can be maintained despite ongoing changes in neuronal ensemble composition.

eLife Assessment

This valuable study presents a tool that uses brain anatomy to predict the layout and size of early visual maps, and it is strengthened by the use of a large and diverse collection of scans to examine differences across people and groups. The evidence is solid for the general usefulness of the approach, but incomplete for some of the broader claims about prediction accuracy and use across data sets, particularly for estimates of map size and for showing that the model improves on repeated functional measurements. This paper is likely to be of significant interest to visual perception researchers, especially those who use fMRI.

eLife Assessment

This important study investigates the role of Nav1.7 voltage-gated sodium channels in regulating excitability of human dorsal root ganglion (hDRG) neurons. The authors characterize a previously identified Nav1.7 channel inhibitor using recombinant channels and human neurons. The study convincingly shows that inhibition of Nav1.7 channels with AM-2099 causes a modest decrease in neuronal excitability and prolongs the refractory period. This work offers new insights into the mechanism of clinically relevant pharmacological targets for pain relief.

eLife Assessment

This short report is an important study that visual acuity declines nonlinearly with cone dropout, while eye motion partially compensates by improving sampling from remaining cones. The method for experimentally simulating cone dropout is compelling, leveraging state-of-the-art imaging and testing in human subjects.

eLife Assessment

This valuable study analyses correlations between traits of Chinese frog species and their Red List status and finds differences between adults and larvae. Of broad relevance, this solid study makes the statement to consider different life-cycle stages when assessing species extinction risks, although many conclusions are based on limited data and thus offer hypotheses rather than direct conservation advice.

eLife Assessment

This work provides a fundamental advance through a detailed, integrative analysis of how the tsetse fly feeds on blood, demonstrating that successful penetration depends on subtle structural adaptations rather than extreme forces or unusual anatomy. By combining high-resolution imaging, innovative biomechanical measurements, and experiments on artificial skin, the study offers complementary and compelling evidence, with clear data supporting a robust mechanistic interpretation. These findings have broad significance, as they clarify the biomechanics of vector feeding and have implications for the transmission of diseases such as African trypanosomiasis across diverse hosts.

eLife Assessment

This valuable work addresses a longstanding question of how the extant genetic code came to be selected and conserved almost universally across life. Using a mutational approach and a small set of reporters, the authors demonstrate that the mutational impact was similar for non-standard genetic codes. The data provide solid support for the claim of having provided experimental verification of the error minimization theory.

eLife Assessment

This important study highlights how cell size influences various cellular responses, with a particular focus on ferroptosis. The evidence presented is convincing, employing multiple model systems and experimental approaches to support the conclusions. This work will be of significant interest to the fields of cell size, ferroptosis, and cancer biology.

eLife Assessment

This study investigates the role of the Z-disc protein Zasp52 in Drosophila flight muscles and provides evidence that an intrinsically disordered region (IDR) helps to stabilize and promote the localization of the protein to the Z-disc. Overall, this represents an important study that provides insights into Z-disc function and maintenance. The data are convincing, supported by strong genetic evidence and behavioral tests, well-controlled experiments, and detailed statistical analyses. Characterization of a new actin-binding motif mutant and FRAP analysis further support the functional importance of the Zasp52 IDR.

eLife Assessment

This important study identified Mex3a protein with dual RNA-binding protein/ubiquitin ligase function as a pivotal regulator of olfactory sensory neurons (OSN) differentiation and lineage fidelity. The authors employed a combination of systems biology approaches (e.g., single-cell RNA sequencing, proteomics) and newly developed animal models (e.g., HyperTRIBE) to provide solid evidence that abrogation of Mex3a disrupts cilia structure and polarity of OSNs. Notwithstanding that this article is of a broad potential interest across different biomedical disciplines ranging from RNA to developmental biology, additional mechanistic data connecting identified Mex3a mRNA targets and ensuing OSN phenotypes would further strengthen this study.

eLife Assessment

This manuscript presents important new findings showing that the transcription factor and regulator of lipid and glucose metabolism PPARγ is methylated by the enzyme SETD6. The data convincingly demonstrate that methylation of PPARγ by SETD6 regulates its function in controlling transcription of lipid storage and metabolism genes and thereby modulates lipid accumulation in liver cells. This work uncovers a new role for post-translational modulation by lysine methylation in controlling transcription factor activity and lipid metabolism in a relevant physiological context.

eLife Assessment

In this useful manuscript, Yang et al attempt to show that platelet recruitment to the liver via macrophages contributes to APAP-induced liver injury, but there were many areas where the data supporting the conclusions were incomplete. For example, the idea that platelets only affected KC glycolysis, but not the metabolism of other cells, to mediate the phenotype after injury is not adequately supported by the evidence. It is recommended to perform additional experiments to strengthen the conclusions.
