  This useful study holds importance within the focused scope of endometriosis treatment, providing initial evidence of a potential new therapeutic target. The strength of the evidence is solid, as the methods, data, and analyses support the authors' conclusions regarding the specific aims. The study provides promising preliminary evidence of KMO implication in endometriosis, but it falls short of establishing a strong rationale for proposing KNS898 as a treatment for endometriosis given the limitations in evidence and mechanistic insights.

  This important study suggests that the composition of the extracellular matrix in a mouse model of liver fibrosis changes depending on the cause of liver fibrosis. The data could be used as a foundation for future antifibrotic therapies. The strength of evidence is solid with respect to the use of animal models and proteomic analysis. The study provides a helpful inventory of proteins up or down-regulated, but functional analyses are limited and translational data are lacking.

Enhancing Bone Regeneration and Osseointegration using rhPTH(1-34) and Dimeric ^R25C PTH(1-34) in an Osteoporotic Beagle Model

  Using a large animal model, this study demonstrated valuable findings that R25CPTH(1-34), based on a mutation associated with isolated familial hypoparathyroidism, generated an anabolic osteointegration effect comparable to that of native PTH1-34. The translational aspect of this human-to-animal work, aimed at animal-to-human translation for therapeutic purposes, should be highlighted. The study design is simple and straightforward, and the methods used are solid. The authors have addressed all the questions in their revision.

  This study describes the formation of a penetration ring in the rice blast fungus Magnaporthe oryzae during host cell invasion. The work provides useful insights into how the penetration ring facilitates the transition of penetration pegs into invasive hyphae, which leads to a better understanding of plant-pathogen interactions. However, the evidence supporting the function of this novel infection structure remains incomplete and further work is needed to help clarify the exact role of the penetration ring in the infection process.

  This study presents valuable insights into the involvement of miR-26b in the progression of metabolic dysfunction-associated steatohepatitis (MASH). The delivery of microRNA-containing nanoparticles to reduce MASH severity has practical implications as a therapeutic strategy. Whereas convincing evidence is provided on the phenotypic changes produced by miR-26, the analyses of its precise role and function are incomplete and need more comprehensive evaluation including mechanistic studies.

  This study presents valuable new insights into a HIV-associated nephropathy (HIVAN) kidney phenotype in the Tg26 transgenic mouse model, and delineates the kidney cell types that express HIV genes and are injured in these HIV-transgenic mice. A series of compelling experiments demonstrated that PKR inhibition can ameliorate HIVAN with reversal of mitochondrial dysfunction (mainly confined to endothelial cells), a prominent feature shared in other kidney diseases. The data support that inhibition of PKR and mitochondrial dysfunction has potential clinical significance for HIVAN.

  This study provides valuable insights into the complex genetics of dominant optic atrophy. Leveraging a fly model, the investigators provide solid evidence, albeit with small effect sizes, for a dominant negative mechanism of certain pathogenic variants that tend to cause more severe phenotypes, a long held hypothesis in the field. The work is of high interest to those in the optic atrophy and degeneration fields.

  This important paper shows that the anti-gremlin-1 (GREM1) antibody is not effective at treating liver inflammation or fibrosis. Critically, the evidence also challenges existing data on the detection of GREM1 by ELISA in serum or plasma by demonstrating that high-affinity binding of GREM1 to heparin would lead to localisation of GREM1 in the ECM or at the plasma membrane of cells. The conclusions are supported by a convincing, well-controlled set of experiments.

  This fundamental work advances our understanding of the role of Cbfβ in maintaining articular cartilage homeostasis and the underlying mechanisms. The evidence supporting the conclusion is mostly convincing, although including additional experiments and discussions would have strengthened the study. This paper is of potential interest to skeletal biologists and orthopaedic surgeons who study the pathogenesis and the therapeutics of osteoarthritis.
