Proteostasis of organelles in aging and disease

The FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

An update on the landscape of collagen bioactive fragments

The FEBS Journal, EarlyView.
The remodeling of the extracellular matrix releases collagen bioactive fragments, which exert molecular functions and regulate numerous biological processes via several signaling pathways. Here, we summarize the latest findings describing the roles of major bioactive fragments from collagens I, IV, VI, and XVIII in various physiological and ...

GCN2 in proteostasis: structural logic, signalling networks and disease

The FEBS Journal, EarlyView.
Threats to protein synthesis activate the kinase GCN2, initiating the integrated stress response (ISR). GCN2 is triggered by stalled ribosomes and uncharged tRNAs, which accumulate when amino acids are scarce. The ISR adjusts cellular physiology by promoting redox balance, protein quality control, and mitochondrial optimisation.

Contrasting effects of different molecular crowding environments on base‐pair opening/closing dynamics of DNA triplex structures

The FEBS Journal, EarlyView.
Base‐pair opening and closing regulate nucleic‐acid structure, stability, and function, but how these motions behave under intracellular molecular crowding remains unclear. Using NMR, we quantified these dynamics in a DNA triplex under two crowder‐reconstituted environments that mimic cellular crowding.

Signal Transducer and Activator of Transcription (STAT) Proteins Regulate Mucosal‐Associated Invariant T (MAIT) Cell Function

Immunology, EarlyView.
Integrated transcriptomic, proteomic and flow cytometry analyses reveal that STAT1 negatively regulates MAIT cell effector and glycolytic functions, while STAT3, STAT5 and HIF1α act as positive modulators. Targeting these pathways may offer new strategies to restore MAIT cell function in immune dysregulation and cancer.

The Complex Relation of Branched‐Chain Amino Acids and Inflammation in the Obesity and Diabetes Context

Obesity Reviews, EarlyView.
ABSTRACT In a scenario with increasing cases of obesity and diabetes worldwide, branched‐chain amino acids (BCAA) metabolism has become an important factor in the understanding of these pathologies. More recently, its chronic high plasma levels have been postulated, alongside glucose, inflammatory factors, and other molecules, as an important ...
