  eLife Assessment

  This useful study reveals that as C. elegans, a poikilothermic ("cold-blooded") animal, adapt to cold (4ºC), they display a drastic reduction in translation (assessed by polysome profiling and SUNSET). The remaining translation (by ribo-seq) correlates with mRNA levels (by RNA-seq), and the changes in gene expression at least partially require IRE-1, an established endoplasmic reticulum stress sensor. The reviewers consider the data assessing global translation and RNA expression upon cold exposure and the data demonstrating the requirement of ire-1 to be solid, but the conclusion that "transcription" is the major regulatory step and "lipid changes" can be a signal for IRE-1 activation in cold adapted worms needs substantially more evidence. Overall, this study demonstrated a good correlation between translation and RNA levels and yielded an inventory of gene changes as C. elegans adapt to cold, and will be of general interest to researchers interested in stress response and cold adaptation.

  eLife Assessment

  This important study reveals that the nucleolar protein Treacle undergoes liquid-liquid phase separation in vitro and in vivo. It provides convincing evidence that the ability of Treacle to form phase-separated condensates is necessary for the proper formation of the fibrillar center of the nucleolus, rRNA transcription, and rDNA repair. These findings will be of interest to the communities studying biomolecular condensates, nucleolar organization, and ribosome biogenesis.
