YTHDC1 Orchestrates Glucose and Glutamate Rewiring to Overcome Lethal Metabolic Stress in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
Lai et al. find that m6A reader YTHDC1 is specifically overexpressed in triple‐negative breast cancer (TNBC) and orchestrates glucose and glutamine metabolism in an m6A‐dependent manner to confer robust adaptability to lethal metabolic stress. Leveraging YTHDC1 knockdown‐induced metabolic vulnerability, an ATF4 mRNA‐targeted nanotherapy is developed to

Metal–Metal Cooperative C─F and S─F Bond Cleavage by Low‐Valent Tetracobalt Clusters and Water‐Assisted Fluoroarene Hydrodefluorination

Angewandte Chemie, EarlyView.
Self‐assembled tetrahedral CoI4 clusters supported by simple bipyridine‐based ligands undergo core rearrangement to cleave S─F and C(sp2)─F bond, forming fluoride‐bridged tetracobalt(II)‐oxo clusters, while exposure of cobalt(I) clusters to molecular oxygen yields cubane‐type cobalt(III) oxo clusters.

Antigen‐Detected NMR for Minimal Epitope Engineering and Structure‐Guided Selection of a NaV1.7‐Selective Nanobody

Advanced Science, EarlyView.
A minimal extracellular epitope from voltage‐gated sodium channel NaV1.7 was engineered into an isotope‐labelled antigen for antigen‐detected nuclear magnetic resonance (NMR). Together with AlphaFold2 (AF2), this enabled structure‐guided selection of R4C8, a human NaV1.7‐selective nanobody that labels fixed NaV1.7‐expressing cells and produces staining

High-density element concentrations in fish from subtidal to hadal zones of the Pacific Ocean

Heliyon, 2018
Anthropogenic use of high density, toxic elements results in marine pollution which is bio-accumulating throughout marine food webs. While there have been several studies in various locations analyzing such elements in fish, few have investigated ...

Upadacitinib Restrains the Pathogenic Fitness of CD4+ T Cells and Aberrant B Cell Programming in Optic Neuritis

Advanced Science, EarlyView.
Single‐cell profiling and functional perturbation reveal coordinated JAK1‐pSTAT3 downstream programs in optic neuritis, including MCL1‐dependent fitness of pathogenic CD4+ Tem cells and glycolysis‐linked, cholesterol‐sensitive B‐cell responses associated with RORA. Upadacitinib disrupts this reciprocal T‐B‐cell circuit and alleviates neuroinflammation,

Emerging Materials and Future Strategies for Solid Oxide Electrochemical Cells

Advanced Energy Materials, EarlyView.
Solid oxide electrochemical cells operate under strongly coupled electrochemical and thermodynamic conditions, where performance is constrained by interactions among crystal structure, defect chemistry, and interfacial evolution. This review, based on a structure‐defect‐property‐durability framework, reveals the roles of lattice symmetry and defect ...
