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

Inhibition of Ornithine Decarboxylase 1 Mitigates Denervation‐Induced Muscle Atrophy by Suppressing Proteolysis and Preserving Muscle Stem Cell Homeostasis

Cell Proliferation, EarlyView.
Polyamine metabolism is innervation responsive and involved in denervation‐induced muscle atrophy. Inhibition of polyamine metabolism attenuates muscle atrophy by restraining proteolysis and preserving MuSCs homeostasis. Denervation‐induced activation of FAP‐derived FGF7 drives premature MuSCs activation, while DFMO suppresses this paracrine cue to ...

Oxygen‐independent expression of HIF‐1α during the cell cycle in hepatocellular carcinoma cells controls essential metabolic pathways under normoxia

The FEBS Journal, EarlyView.
In Huh7 cells, HIF‐1α is essential as it maintains the expression of proteins involved in glycolysis and steroid/cholesterol biosynthesis both under normoxia and hypoxia. On the other hand, in HeLa cells, these pathways are induced by HIF‐1α only under hypoxia.

The ribosome‐associated complex regulates cytosolic translation upon mitoprotein‐induced stress

The FEBS Journal, EarlyView.
Defects in mitochondrial protein import trigger a stress response. The contribution of translation regulation to such a response is only partially understood. We demonstrate that the deletion of mitochondrial surface proteins (TOM70/TOM71) leads to defects in mitochondrial biogenesis and slow growth.

RNF13 is a previously undescribed interactor of iduronate 2‐sulfatase that modifies its glycosylation and maturation

The FEBS Journal, EarlyView.
Iduronate 2‐sulfatase (IDS; purple) is expressed as a precursor protein that goes through multiple steps of maturation, modification, and trafficking to become an active lysosomal enzyme that degrades glycosaminoglycans. Our study shows that the transmembrane ubiquitin ligases RNF13 (orange) and RNF167 (pink) heterodimerize, affecting IDS intracellular

Lock, relax, load, and shoot: a molecular perspective on Nedd4 regulation

The FEBS Journal, EarlyView.
Structural basis of inactive and active states of the Nedd4 HECT E3 ligase subfamily, following a ‘lock, relax, load, and shoot’ mechanism. In the locked, autoinhibited state, intramolecular domain interactions restrain the HECT domain. Relaxation releases these restraints, allowing loading of ubiquitin onto the catalytic cysteine, followed by the ...
