This paper demonstrates the genetic architecture of heart mitochondrial proteome that influences cardiac hypertrophy, using a panel of inbred mouse strains called the Hybrid Mouse Diversity Panel (HMDP). The HDM panel is a very powerful tool to study the genetic basis of various physiological and pathological processes in mice. The authors have used this panel extensively before, and in this paper, they extend their proteomic studies to demonstrate the genetic basis of cardiac hypertrophy. The studies will allow us to better understand the genetics of hypertrophic cardiomyopathy.

This important study greatly expands our knowledge of the fossil record of Mermithid nematodes, modern members of which are ecologically important parasitoids of arthropods, annelids and mollusks today. The most important finding, convincingly presented, is that mermithids parasitized a number of insect clades in the Cretaceous that they are not known to infect today or in Cenozoic amber. The evidence for a shift in exploited hosts from heterometabolous insects in the Cretaceous to holometabolous ones in the Miocene is solid but could be made exceptional by adding a small quantitative analysis with confidence intervals and bar plots from the data already compiled in the supplementary material; potential collection bias should be addressed as well.

This fundamental work uses deep neural networks to simulate activity evoked by a wide range of stimuli and demonstrates systematic differences in latent population representations between hearing-impaired and normal-hearing animals that are consistent with impaired representations of speech in noise. While the evidence supporting the conclusions is compelling, additional analyses would facilitate the generalizability of the neural-network approach. The research will be of interest to auditory neuroscientists and computational scientists.

This manuscript provides valuable data gathered using a new video fluoroscopy method by which movements of artificial joints can be visualized in real time. These solid data add to the understanding of the links between symptoms of unstable joints after total knee replacement and actual joint instability. The paper should be of interest to those who study biomechanics after total joint replacement.

In this study, Li and al describe valuable insights into the mechanisms underlying sex-differences diet-induced obesity in mice, with a role of macrophage-derived RELMa secretion in female-specific protection. They provide solid evidence for the impact of RELMa signaling in eosinophil recruitment for diet-induced obesity protection in female mice. Single-cell RNA-seq analysis of the stromal vascular fraction of control and RELMa deficient animals methods were used to investigate molecular mechanisms underlying the protection as a powerful method, although the analysis of this data is difficult to evaluate with incomplete methodological information.

eLife assessment

In vertebrates, ciliary motility is powered by axonemal dyneins, known as OADs, tethered to doublet microtubules by a pentameric docking complex including the Armc4 and Calaxin subunits. This valuable study combines zebrafish genetics with cryo-electron tomography to convincingly show that Armc4 plays a critical role in the docking of OAD and that Calaxin stabilizes the molecular interaction. The work will be of interest to those studying the structure and function of the axoneme, and motile cilia in general.

eLife assessment

This important study combines behavior, computational modelling and magnetic resonance spectroscopy to address the question whether age-related declines in learning are driven by declines in working memory or deficiencies of the RL system. The general approach is solid, but the presented evidence to support the papers' main claims could be stronger. With additional analyses and adaptation of the main claims, the paper could be of high interest for researchers in the field of cognitive aging and decision making.

The authors present a manuscript aiming to understand the mechanism(s) underlying myeloid bias in HSCs, specifically focused on the role of Pcgf1, and therefore PRC1.1, in the regulation of hematopoiesis. This important work is of interest to the community of researchers interested in myeloid differentiation, lineage fate decisions in hematopoietic stem cells, and the molecular mechanisms that contribute to the initiation of myeloid malignancies. The methods are rigorous and the results convincingly support the authors' conclusions.

eLife assessment

This is a valuable paper describing an attempt to reconstruct the evolution of Dicer. Using ancestral reconstruction approaches, the authors carefully examine the biochemical characteristics of reconstructed proteins at various junction points in the animal lineage. They provide solid evidence that the deepest ancestrally reconstructed protein has double-stranded RNA stimulated ATPase activity and that this characteristic was lost along the vertebrate lineage. This paper will be of interest to scientists in the RNA-protein interaction and protein evolution fields.

eLife assessment

The authors have established new formulas to predict maximum oxygen uptake for cyclists and runners based on submaximal exercise testing and anthropometric characteristics. This is an important study with a large and comprehensive dataset, which may be helpful for many exercise labs. The work is convincing, using appropriate and validated methodology in line with the current state-of-the-art, as shown by references to common exercise books.

In the current manuscript, the authors study the effects of hypoxia or genetic and pharmacologic modulation of the hypoxic pathways on T cells. The findings about T cells sense hypoxia and how hypoxia affects T cell (and CAR T cell) differentiation and function are significant and interesting for the field. The data supporting these findings are mostly robust, yet some questions remain open and some statements seem unsupported by evidence.

This fundamental work substantially advances our understanding of polymer physics underpinnings of genome folding, organization, and regulation. The conclusions are supported by both convincing computer simulations and analytical theory. The work will be of significant interest to the genome folding community.

eLife assessment

This manuscript will be of interest to scientists in the field of tissue injury and repair. It provides novel molecular mechanisms of a transcription factor, Prrx1, in fibroblast activation following lung injury. Overall, the work suggests that PRRX1 plays a functional role downstream of TGFb1 to elicit some aspects of the fibrotic response and that PRRX1 could represent an important therapeutic target to treat fibrosis. The strengths of this work are the multiple approaches applying human and mouse lung tissue used by the authors to test the role of PRRX1 in lung fibrosis, however, in its current form, major limitations need to be addressed.

The study has advanced our mechanistic understanding of lung regeneration. While the importance of regeneration of alveolar capillaries for long response to injury has been long recognized, the regulation of this process has not been well understood. Your study provides novel, comprehensive, and compelling evidence that the expression of the transcription factor Atf3 in alveolar capillary endothelial cells plays a critical role in the regeneration of alveolar capillaries following lung injury.

eLife assessment

This study concerns an important area, that of monoallelic expression, but the study does not provide sufficient information about the candidate regulatory RNA to provide a significant advance over previous work, which should also be discussed in more detail.

eLife assessment

The study examines the principles according to which neurons connect to each other in the brain. The authors find that data could be best explained by the homophillic wiring principle where neurons preferentially connect to neurons within overlapping groups. The work will provide a valuable resource to the neuroscience community once analyses are standardized across various datasets included.

eLife assessment

This valuable work advances our understanding of the acoustic features driving the attraction of female mice to male vocalizations. The evidence supporting the conclusions is solid, with well-designed place preference assays and manipulations of male song structure. The work will be of broad interest to neurobiologists and ethologists working on mouse social interactions, auditory processing and communication.

This important manuscript combines cryo-EM and a suite of compelling whole cell and proteoliposome transport assays to establish the mechanism and structure of the full-length human SLC26A6 chloride/bicarbonate exchangers, including the first partial view of the previously unresolved IVS region of an SLC26 STAS domain. In combination with prior studies on additional SLC26 paralogs, including the SLC26A9 paralog initially reported by the same group, the study provides broadly relevant insights into the mechanistic diversity of the SLC26 transporters. This study is of interest to the biophysics community and the field of membrane transport.

This is a useful study for scientists interested in cell polarity, epithelial morphogenesis, cancer, and primary cilia. The authors investigate the role of CRB3 in regulating these processes by using a combination of a mammary epithelial cell-specific conditional Crb3 knockout mouse model, and cellular, molecular and biochemical approaches. The results, which are solid, supporting and extending previous findings, suggest that CRB3 affects ciliogenesis by a mechanism involving Rab11 and gamma-TuRC.
