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 ...

Mitochondrial transfer in acute myeloid leukaemia and multiple myeloma: Mechanisms, consequences and potential therapeutic opportunities

The FEBS Journal, EarlyView.
Mitochondria can be transferred from bone marrow cells to cancer cells in acute myeloid leukaemia and multiple myeloma, boosting tumour energy production, growth, and drug resistance. This review highlights key transfer mechanisms and shows how targeting mitochondrial movement and dynamics may offer new therapeutic strategies to limit cancer ...

Biogenesis of TNF‐α‐insights into proteostasis and inflammation

The FEBS Journal, EarlyView.
TNF‐α biogenesis, trafficking, and signalling are tightly and reciprocally coupled to cellular proteostasis systems, including ER chaperones and endoplasmic reticulum‐associated degradation. This bidirectional crosstalk determines whether TNF‐α responses are adaptive or proteotoxic.

Inflammation‐Regeneration Axis of Dental Pulp Stem Cells: Wnt/NF‐κB Crosstalk

International Endodontic Journal, EarlyView.
ABSTRACT Background Inflammation critically determines dental pulp regenerative outcomes, with dental pulp stem cells (DPSCs) orchestrating tissue homeostasis through differentiation, self‐renewal and immunomodulation processes dynamically regulated by Wnt/β‐catenin and NF‐κB signaling crosstalk.
