Onion‐Mitochondria Inhibit Lipopolysaccharide‐Induced Acute Lung Injury by Shaping Lung Macrophage Mitochondrial Function

Advanced Science, EarlyView.
Proposed model of orally administered onion mitochondria (O‐Mit) uptake by lung macrophages and fuse with macrophage mitochondria (M‐Mit). This fusion reprograms the metabolism of dysfunctional M‐Mit in lipopolysaccharide‐induced murine acute lung injury by modulating dynamin‐related protein 1 (DRP1) phosphorylation and cardiolipin peroxidation ...

Mechanical Cues Regulate Cargo Sorting and Export at the Golgi

Advanced Science, EarlyView.
A pathway is identified linking extracellular matrix stiffness to secretion via Src–FAK–AMPK–GBF1 signaling. Golgi‐localized GBF1 acts as a mechanotransducer whose phosphorylation controls post‐Golgi cargo sorting toward secretion or lysosomal degradation.

eIF4E Enriched Extracellular Vesicles Induce Immunosuppressive Macrophages through HMGCR‐Mediated Metabolic Rewiring

Advanced Science, EarlyView.
Here, it is revealed that ovarian cancer cells release extracellular vesicles enriched with eIF4E, which alters protein production in macrophages. This leads to increased expression of 3‐hydroxy‐3‐methyl‐glutaryl‐coenzyme A reductase (HMGCR), boosting cholesterol synthesis and activating an immunosuppressive pathway through X‐box binding protein 1 and ...

TWF2 Drives Tumor Progression and Sunitinib Resistance in Renal Cell Carcinoma through Hippo Signaling Suppression

Advanced Science, EarlyView.
Twinfilin actin‐binding protein (TWF2) is upregulated in sunitinib‐resistant renal cell carcinoma (RCC) cells, where it interacts with YAP and protects YAP from degradation. Stabilized YAP translocates into the nucleus and activates transcription of target genes, promoting RCC progression and drug resistance.

Novel Evolutionarily Conserved Oncogene COA4 is Driven by KRAS Mutant and Promotes Cancer Metastasis Through Dual Mitochondrial Metabolism‐Dependent and ‐Independent Mechanisms

Advanced Science, EarlyView.
In KRAS‐mutant tumors, KRAS transcriptionally upregulates COA4 via the PI3K/AKT/E2F1 axis, promoting metastasis. Mechanistically, COA4 enhances tumor cell migration through dual pathways: within mitochondria, it boosts oxidative phosphorylation; in the cytoplasm, it binds and activates CDC42 to stimulate pseudopodia formation.
