  Evaluation Summary:

  This manuscript describes the identification of an animal model that reproduces several features presented in Ogden syndrome patients and reveals the roles of two N-terminal acetyltransferases in mouse development. It will be of interest to the readers in the field of protein acetylation and modification, and also to the scientific community involved in rare diseases and syndrome studies.

  Evaluation Summary:

  The manuscript by Rosello et al. represents a major advance in implementation of cutting-edge genome editing methodologies in the zebrafish. The study seeks to describe optimized tools for precise base editing in zebrafish and to demonstrate their effective application. Overall, this study demonstrates that cytosine base editing is an efficient and powerful method for introducing precise in vivo edits into the zebrafish genome, and will be of interest to scientists who use zebrafish and other genetic systems to model human development and disease.

  Evaluation Summary:

  This is an elegant study demonstrating the emergence of mesoderm-derived beta-like cells following beta-cell ablation in an endothelial cell deficient context. These findings will be of interest to scientists in the areas of regeneration and reprogramming, as they reveal a previously unknown degree of germ layer plasticity in the embryo. In the long term the study has potential impact in the diabetes field, as it reveals a novel path for redirecting somatic cells into insulin-producing cells in an in vivo context.

  Summary: The authors seek to tackle the question of exercise and inactivity in Duchenne muscular dystrophy, an important and unsolved issue. They use the zebrafish model system and two paradigms, one an inactivity paradigm (using tricaine) and the other an exercise paradigm using NMES. They find that inactivity worsens the dystrophic phenotype, and that different exercise paradigms impact the dystrophic phenotype differently. Overall this is an important study with exciting data and a potential to impact our understanding of exercise in DMD. However, as described below, all reviewers felt that several critical experimental considerations are necessary to consider in order to substantiate the data claims.
