  eLife Assessment

  This potentially valuable manuscript focuses on the phosphorylation of residue T495 as a mechanism to inactivate HSP70 and disrupt cell cycle progression in response to DNA damage. The evidence supporting this model is solid, but would be significantly strengthened by additional studies defining the extent of T495 phosphorylation induced by DNA damage, identifying the kinase responsible for phosphorylating T495 of HSP70, and further elucidation of the functional implications of T495 phosphorylation in human cells. This work will be of interest to scientists focused on topics including chaperone biology, proteostasis, cell cycle progression, and DNA damage.

  This valuable study suggests that capsaicin nanoparticle administration in rats activates the transcription factor Nrf2 by directly binding to its repressor, KEAP1, leading to the induction of cytoprotective genes and preventing alcohol-induced gastric damage, offering a potential avenue for treating alcoholism-related gastric disorders. The authors provide solid evidence through a wealth of biochemical experiments in vitro, in cultured cells as well as in a rat model. The work will be of great interest to researchers studying oxidative damage in a variety of different diseases and the exploitation of molecules for therapeutic approaches.

  This important study highlights the role of MIRO1 in regulating mitochondrial oxidative phosphorylation in smooth muscle cells, a process that appears necessary to sustain their proliferation. Overall, the work provides convincing evidence that mitochondrial positioning and function influence vascular disease, although several bioenergetic and mechanistic aspects would benefit from deeper investigation.

• Curated by eLife

  eLife Assessment

  In this manuscript, based on electron microscopy observations of C. elegans embryos, the authors make the bold claim that the plasma membrane ruptures during cell division and that closure of this opening by membrane extension contributes to cytokinesis. Although the findings are potentially valuable, the evidence in support of the authors' claims is inadequate.
