  eLife Assessment

  This manuscript reports valuable results on the role of MDC1 and Treacle in DSB repair in rDNA repeats. It has been previously established that MDC1 is replaced by Treacle as the main adaptor in the nucleolar DNA damage response. This work provides convincing evidence that MDC1 is required for the recruitment of RAD51 and BRCA1 to DSBs in rDNA. The work involves multiple MDC1 knockout models and establishes that RFN8-RNF168 act downstream of MDC1 in the recruitment of the HR machinery to nucleolar DSBs.

  eLife Assessment

  This fundamental study reveals that aging in yeast leads to chromosome mis-segregation due to asymmetric partitioning of chromosomes, driven by disruption of the nuclear pore complex and pre-mRNA leakage. The findings are convincingly supported by carefully-designed experimental data with a combination of genetic, molecular biology and cell biology approaches.

  eLife Assessment

  How secretion is regulated during cell division and how membrane trafficking factors cooperate with the cytoskeleton during cell division remain poorly understood. In this work the authors find protein-protein interactions and localization dependencies between the polymeric septin cytoskeleton and the exocyst complex, using fission yeast as a model organism and using alphafold 3 based structural predictions. The work provides a valuable body of new information that will be of great interest to the cell biology community. The evidence is solid and provides the authors and the community a framework to test if the identified interfaces reflect bona fide interaction sites in vivo and in vitro in future.
