      This fundamental work extends our understanding of the role of TGFβ2 as a modulator of mechanosensing in the eye and identifies the TRPV4 ion channel as a common regulator of Trabecular Meshwork (TM) contractility and pathological OHT and the data and evidence provided are convincing. This work will clearly be of interest to researchers investigating the role of mechanosensors in the TM and may underpin future research into treatments that aim to lower intra ocular pressure. This work will additionally be of interest to the growing field of researchers investigating the regulation of force sensing via ion channels and their roles in health and disease, in particular the ion channel TRPV4.

      In this important study, the authors have performed a zebrafish drug screen to identify suppressors of atherogenic lipoproteins. They utilize a well-established LipoGlo assay to find molecules that modulate these lipoproteins, identifying 49 potential hits. They perform some validation experiments, including studies linking enoxolone to its likely inhibitory effect on a specific transcription factor, HNF4alpha. Overall, the results are convincing and robust, and will open up new areas of exploration for those investigators interested in in vivo lipid biology.

      This study presents compelling evidence that the denitrosylase SCoR2 regulates cardioprotective metabolic reprogramming in the heart following ischemia/reperfusion injury. The findings are supported by a novel multi-omics approach and the integration of mouse and human data, which provides valuable insights into S-nitrosylation and cardiac metabolism. However, some conclusions remain limited by unresolved methodological issues that warrant clarification.

      eLife Assessment

      This study presents a useful finding on the effects of arginine vasopressin (AVP) on islet cells in pancreatic tissue slices, using technically sophisticated spatio-temporal calcium recordings to confirm that AVP influences α and β cells differently depending on glucose concentrations. While the study’s methods – particularly the calcium imaging techniques and peptide ligand design targeting V1b receptors – are strong, the reviewers were concerned about several aspects of the experimental design. The results on β-cell responses are incomplete and insufficient to support the manuscript’s claims, especially due to the high variability of islet responses and lack of mechanistic and functional (hormone release) data. There are also concerns about the possibility of off-target effects and suboptimal receptor specificity: the study would be significantly strengthened by inclusion of signaling pathway interrogation, hormone output assays, genetic validation (e.g., β cell-specific deletion of V1br), and receptor localization. The work will still be of interest to researchers studying islet physiology in the context of health and diabetes.

      This study offers valuable insights into the role of miR-283 in ventral-lateral neurons (LNvs) and its impact on senescence, cardiac function, and aging in the Drosophila melanogaster model. However, the evidence supporting some of the conclusions remains incomplete, and further mechanistic studies are needed to clarify how miR-283 affects normal aging and influences exercise adaptations. Nonetheless, the work can be of interest to cell biologists studying miRNA biology, aging, and age-related diseases.

      This study presents a useful contribution to understanding zinc regulation of sperm physiology, specifically its inhibitory effects on the sperm-specific potassium channel Slo3. However, the evidence supporting the claims is incomplete, as critical experimental controls are lacking, key mechanistic aspects remain insufficiently explored, and experimental descriptions are often inadequate, making it difficult to fully assess the findings. Strengthening the study with additional electrophysiological recordings in sperm cells, improved imaging controls, and clearer methodological descriptions would enhance its impact and rigor.

      This manuscript represents a fundamental contribution demonstrating that fentanyl-induced respiratory depression can be reversed with a peripherally-restricted mu opioid receptor antagonist. The paper reports compelling and rigorous physiological, pharmacokinetic, and behavioral evidence supporting this major claim, and furthers mechanistic understanding of how peripheral opioid receptors contribute to respiratory depression. These findings reshape our understanding of opioid-related effects on respiration and have significant therapeutic implications given that medications currently used to reverse opioid overdose (such as naloxone) produce severe aversive and withdrawal effects via actions within the central nervous system.
