Age‐Related Lamin B1 Deficiency Activates SLC7A11‐Dependent Disulfidptosis to Impair Osteogenesis via Intercepting Mitochondrial Fission

open access: yesAdvanced Science, EarlyView.
This study reveals that age‐related LMNB1 deficiency in mesenchymal stem cells epigenetically upregulates SLC7A11, triggering actin disulfidptosis and mitochondrial dysfunction. This cascade impairs bone formation in senile osteoporosis. Furthermore, researchers identified the FDA‐approved drug naldemedine as a targeted SLC7A11 inhibitor to reverse ...

H4K12 Lactylation Impairs Dopaminergic Neuron Energy Metabolism via the HIF‐1α/NDUFS1 Pathway in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
Lactate and H4K12la are elevated in Parkinson's disease. Mechanistically, p300‐mediated H4K12la enrichment at the HIF‐1α promoter upregulates HIF‐1α, which represses Ndufs1, impairing mitochondrial respiration and energy homeostasis in DA neurons.

Supramolecular Cadmium‐Telluride Proteoliposomal Assemblies for Real‐Time Detection of Protein‐Catalyzed Pt(II)‐Complexes Transmembrane Translocation: Cu(I)‐Pumps Are Electrogenic Pt(II)‐Drug Uniporters

open access: yesAngewandte Chemie, EarlyView.
Supramolecular mercaptosuccinic acid‐capped CdTe core‐type quantum dot‐encapsulated proteoliposome assemblies (MSA‐CdTe QD PLs) have been developed to study and unambiguously demonstrate real‐time transporter‐mediated turnover translocation of Pt(II)‐based complexes by transmembrane Cu(I) P‐type ATPase pumps (CopA).

The Role of Chloride Homeostasis in Neuronal Plasticity

open access: yes
Chloride is an abundant anion with many important physiological functions. In the brain, it has been shown to intervene with many neuronal plasticity processes such as proliferation, migration, and synaptic plasticity.

Semi‐Artificial Photosynthesis Enables Light‐Driven Biomanufacturing in Non‐Photosynthetic Bacteria

open access: yesAdvanced Science, EarlyView.
A non‐invasive strategy exploits endogenous H2S metabolism in B. subtilis to drive in situ CdS biomineralization, enabling tight bio‐abiotic contact without genetic modification. Light harvested by the biomineralized nanoparticles powers NADPH regeneration, elevating 2’‐fucosyllactose and surfactin titres two‐ to three‐fold.

Structure and Function of a Multi‐Megadalton Virus‐Like Proteolytic Dodecahedron

open access: yesAngewandte Chemie, EarlyView.
Zuzalysin, a virulence metallopeptidase of the periodontal pathogen Porphyromonas gingivalis, is secreted as a latent, flexible ≈95‐kDa monomer. Calcium triggers cysteine‐switch activation and hierarchical assembly into pentamers, bipentamers, tripentamers, and a ≈5.6‐MDa, ≈355‐Å dodecahedron. Structures at 1.8–3.6 Å reveal a virus‐sized catalytic cage
