  Evaluation Summary:

  This is an interesting and informative study reporting on the molecular features of reversible hair graying in humans and the connection with psychological stress. The study appears to have been very well conducted and the interpretations are generally supported by the data. While the results are primarily correlative at this stage, this work will set the stage for future more mechanistic studies and represents an important conceptual and methodological advance.

  Evaluation Summary:

  Ferroptotic cell death underlies tissue dysfunction inflicted by transient ischemia/reperfusion particularly in renal tissue. Here, the authors provide experimental evidence in animal models and human biopsies that mild and severe ischemic stress trigger distinctive cellular responses in proximal tubular cells which decide upon whether or not tissue may regenerate or fail. This is further corroborated in a genetic mouse model with mild ischemic stress-induced ablation of the key ferroptosis regulator glutathione peroxidase 4 (GPX4). These studies will be of significant interest both to those studying acute kidney injury and others interested in ischemic injury in other organ systems.

  Evaluation summary:

  This manuscript will be of interest for scientists interested in cell cycle, DNA repair, transcription and genome stability opening a new chapter in studies of cell cycle dependent regulation of DSB repair. Much of the prior work has focused on cell cycle-driven post-translational regulatory modification of DSB end resection, whereas the current work finds transcriptional programs are equally, if not more, important in controlling resection in G0. This could open possibilities for gene therapy in post-mitotic tissues. The data are of high quality and the conclusions drawn are supported by the experimental evidence.

  Evaluation Summary:

  This manuscript is of potential interest to the field of cell death research in terms of understanding basic mechanisms and in the context of disease. The authors have used a broad range of methodologies and identified key phosphorylation sites on the protein kinase RIPK3 that determine whether cells undergo necroptotic or apoptotic cell death. The authors examine this phosphorylation event in the context of corpus luteum regression.

Quantitative mapping of dense microtubule arrays in mammalian neurons

4. Lukas C Kapitein

• Curated by eLife

  Evaluation Summary:

  In this manuscript, Katrukha et al. use STED and Expansion Microscopy techniques to map the distribution of different microtubule populations within the dendrites of neurons, a challenging task due to the tight bundling of microtubules along neuronal processes. They are able to show that dendritic microtubules are either acetylated or tyrosinated, but rarely have both or neither of these post-translational modifications. The strength of this paper is the quality of the experiments, the thoroughness of the analyses, and most importantly the transparent and critical discussion of the limitations the authors have encountered. This manuscript is of broad interest to the cytoskeletal and neurobiology fields.

  Evaluation Summary:

  ESCRT-III is a conserved hetero-oligomeric membrane remodeling machine known to impact a number of cellular phenomena, yet mechanistic details of its function have remained enigmatic. This work identifies critical inter-subunit contact sites critical for ESCRT-III assembly and function.
