Mechanical Force Promotes Mitochondrial Transfer From Macrophages to BMSCs to Enhance Bone Formation

Cell Proliferation, EarlyView.
Mechanical tension activates Drp1‐mediated mitochondrial fission in macrophages, facilitating the release of Mito‐EVs that are subsequently transferred to BMSCs. Additionally, the CD200R‐CD200 interaction enhances the uptake of these mechanically stimulated macrophage‐derived Mito‐EVs by BMSCs, ultimately promoting osteogenic differentiation.

Emerging Role of Ferroptosis in Diabetes and Associated Complications: When Metabolic Dysregulation Meets Cell Death

Cell Proliferation, EarlyView.
This study identifies ferroptosis as a key driver of diabetes and its complications via iron metabolism and lipid peroxidation, elucidates organelle interactions underlying cell vulnerability, and provides insights for targeted therapies against metabolic disorders.

Growth differentiation factor 15 mitigates lipotoxic steatosis by preserving mitochondrial morphodynamics and augmenting fatty acid oxidation in hepatocytes and liver organoids

Diabetes, Obesity and Metabolism, EarlyView.
Abstract Aims Growth differentiation factor 15 (GDF15) has emerged as a promising metabolic regulator with hepatoprotective properties in metabolic dysfunction‐associated steatotic liver disease (MASLD), yet its underlying mechanisms remain elusive.

ER proteostasis meets mitochondrial function: contact sites as hubs of communication and therapeutic targets

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.

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 ...

Opposing roles of DGAT‐mediated lipid droplet biogenesis in the regulation of ferroptosis sensitivity

The FEBS Journal, EarlyView.
Ferroptosis is driven by unrestricted peroxidation of polyunsaturated fatty acyl (PUFA) chains in membrane phospholipids. In triple‐negative breast cancer cells, lipid droplets (LDs) sequester dietary PUFAs, limiting their incorporation into membrane phospholipids, preventing mitochondrial damage, and reducing lipid peroxidation and ferroptosis.

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.

Exercise‐related microRNAs in Caenorhabditis elegans regulate calcium homeostasis and mitochondrial dynamics: Conserved pathways, divergent microRNAs

The FEBS Journal, EarlyView.
Exercise‐related microRNAs cel‐miR‐249‐3p and cel‐miR‐77‐5p in C. elegans regulate lifespan, fitness, mitochondrial morphology and membrane potential. Although lacking direct mammalian orthologs, H2O2‐induced microRNAs mmu‐miR‐181a‐5p and mmu‐miR‐378a‐3p regulate myogenesis, autophagy, mitochondrial content and respiration in murine myoblasts ...
