  This paper will be of interest to those studying DNA replication in the context of chromatin and development. This important study uncovers a new interaction partner for the chromatin protein SuUR and tries to understand how this complex (SUMM4) functions to control under-replication in polytene chromosomes. While the experiments are of high quality and carefully controlled, the data currently do not fully support all the conclusions, particularly as they relate to conclusions about DNA replication timing.

  NOX2 is the most well-studied member of the NADPH oxidase family, membrane enzymes that produce reactive oxygen species (ROS), and the proper function of NOX2 is critical for innate immunity against pathogens in mammals. This study reports a high-resolution structure of the NOX2-p22 complex, providing valuable information for a mechanistic understanding of NOX2 activation at the molecular level.

  This well-presented and sophisticated study provides significant proof-of-concept for the application of the ForensOMICS approach as a new pathway for forensic taphonomy with great promise to advance future research. The solid foundation of the research combining metabolomics, proteomics, and lipidomics is considered very exciting, strong, and expands the boundaries of forensics research.

  Type II topoisomerases are essential players in virtually every aspect of genome organization and function of all organisms. The in vitro data presented here clearly demonstrate that eukaryotic type II topoisomerases phase separate under physiological conditions, forming liquid-liquid condensates, and that the outcomes of type topoisomerase II activity on DNA are altered in these condensates. The experiments and methods are sound, clearly described, and fully support the insightful and carefully formulated interpretation of the data. This work has broad implications for dissecting and delineating the myriad fundamental roles of this centrally important molecule.

  This paper will be of interest to scientists working on cilia, intraflagellar transport, and structural modeling. Using an integrative modeling approach, the paper provides a fundamental structural model for a part of the molecular machinery that is responsible for cilium assembly. However, additional approaches would improve confidence in the as yet incomplete structure model.

  This manuscript presents valuable and significant data on how lipids may accumulate in the tubulointerstitial compartment of the diseased kidney, but the work is largely descriptive, using methods that are inadequate for quantification (colorimetric assays versus mass spec), thus rendering data interpretation not very convincing. Therefore, while a major strength is the presentation of innovative ideas, additional experiments would be needed to support the main conclusions.

  This study shows that cis H3 tail acetylation promotes nucleosome accessibility to H3K4 methyl readers and writers such as MLL1. The findings provide a molecular basis for the long-standing connection between H3 acetylation and H3K4 methylation. Additional evidence is required to fully support the conclusions.
