  This paper presents the important finding that BNIP3/NIX, a mitophagy receptor, and its binding to ATG18 are required for mitophagy during muscle cell reorganization in Drosophila. Although the involvement of the BNIP3-ATG18/WIPI axis in mitophagy induction has been reported in mammalian cell culture systems, this study provides the first compelling evidence for this pathway in vivo in animals. The physiological significance of this BNIP3-dependent mitophagy will require further investigation.

  This study provides valuable insights into the crosstalk between ATG2A with components of the early secretory pathway, namely RAB1A and ARFGAP1. The evidence supporting the claims is convincing. However, the manuscript would benefit from a more in-depth exploration of the details of the role of RAB1A in autophagy and the functional implications of its interaction with ATG2A. In addition, the molecular details of the role of ARFGAP1 in this complex need further clarification

  The authors study how apolipoprotein L1 variants impact inflammation and lipid accumulation in macrophages. The findings will be useful for researchers investigating macrophage metabolism and inflammation. The discovery that the polyamine spermidine in part mediates such effects is interesting, but the supporting evidence for a physiologically relevant role is currently incomplete due to the lack of relevant in vivo studies.

Impact of maximal overexpression of a non-toxic protein on yeast cell physiology

  eLife assessment

  This convincing study advances our understanding of the physiological consequences of the strong overexpression of non-toxic proteins in baker's yeast. The findings suggest that a massive protein burden results in nitrogen starvation and a shift in metabolism likely regulated via the TORC1 pathway, as well as defects in ribosome biogenesis in the nucleolus. The study presents findings and tools that are important for the cell biology and protein homeostasis fields.

  This study reports the important development and characterization of next-generation analogs of the molecule AA263, which was previously identified for its ability to promote adaptive ER proteostasis remodeling. The evidence supporting the conclusions is convincing, with rigorous assays used to benchmark the changes in potency and efficacy of the AA263 analogs as well as AA263 targets. The ability of AA263 analogs to restore the loss of function associated with disease-associated proteins prone to misfolding will be of interest to pharmacologists, chemical biologists, and cell biologists, as well as those working on protein misfolding disorders.
