Heat Stress Triggers Nuclear Invagination and Spatial Compartmentalization of Protein Metabolism
Cell Proliferation, EarlyView.Cells adapt heat stress to shape a nuclear invagination region function as “protein metabolism hotspots”, where both protein production and degradation are enhanced. ABSTRACT Heat stress is a common challenge for cells, causing multiple types of cellular damage while triggering complex stress responses, including the highly conserved mechanism known as

Dissection of Mitochondrial Function via Chemical Perturbation and Single‐Cell Profiling
Cell Proliferation, EarlyView.We establish a systematic framework to dissect mitochondrial function at the module level by combining targeted chemical perturbations with scRNA‐seq. This approach reveals shared and module‐specific programs linking mitochondrial activity to mito‐nuclear communication, stress response, and cell cycle, highlighting the tight coupling between ...

The ALS‐associated E425K mutation uncouples DNAJC7 from the Hsp70 chaperone cycle
The FEBS Journal, EarlyView.DNAJC7 is a J‐domain protein that plays a key role in protein quality control by regulating Hsp70 activity and preventing protein aggregation. We find that the ALS‐associated E425K mutation in DNAJC7 disrupts productive interaction and activation of Hsp70, thereby blocking the transfer and refolding of client proteins such as TDP‐43.

The FEBS Journal, EarlyView.Congenital dyserythropoietic anemia type I (CDA‐I) arises from mutations in Codanin1 and CDIN1. Using quantitative biophysical approaches, we show that disease‐associated mutations disrupt the CDIN1‐Codanin1 complex. Our findings provide critical insights into the molecular mechanism that links protein dysfunction to disturbing chromatin arrangement ...

The FEBS Journal, EarlyView.Proteostasis ensures proper protein folding, modification, and degradation, while its impairment triggers ER stress. Chronic ER stress and maladaptive UPR via the CHOP–ERO1 axis remodel ERMCs, altering calcium signaling and mitochondrial metabolism.
