Tunnelling Nanotube‐Mediated Lysosome Sharing Promotes Osteocyte Survival via Transcellular Autophagy

Cell Proliferation, EarlyView.
This study provides the first definitive identification of tunnelling nanotubes (TNTs) between cultured osteocytes and shows TNT‐mediated lysosome transfer from healthy to stressed cells, restoring autophagic flux and preventing apoptosis. This discovery of transcellular autophagy reveals a new survival mechanism in osteocytes, offering potential ...

Ubiquitin binding by the p62 UBA domain

Over 30 different mutations in p62 UBA have been identified in patients with Paget's disease of bone (PDB). The mechanisms which underlie PDB are poorly understood, although impaired ubiquitin binding has been identified as a mechanism in the onset of ...

Localised Autophagy Inhibition by Nanodiamonds Potentiates Arsenic Therapy With Favourable Safety Profile in Solid Tumours

Cell Proliferation, EarlyView.
This study presents an NDs‐mediated localised combination strategy that integrates autophagy inhibition with low‐dose ATO sensitization, enabling effective tumour suppression while enhancing safety. NDs‐mediated autophagy blockade enhances ATO efficacy while minimising systemic toxicity, highlighting a promising approach for solid tumour treatment ...

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 ...

Disruption of iron metabolism resulting from Dmt1/Slc11a2 deficiency compromises Notch protein degradation and transcriptional activation

The FEBS Journal, EarlyView.
Divalent metal transporter 1 (Dmt1) maintains iron homeostasis and lysosomal proteostasis required for physiological Notch receptor–ligand signaling. Dmt1 loss lowers iron storage capacity (ferritin), increasing intracellular Fe2+, driving ROS and lipid peroxidation, and leading to lysosomal/mitochondrial dysfunction.

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 ...
