Okanin Suppresses the Growth of Colorectal Cancer Cells by Targeting at Peroxiredoxin 5

Advanced Science, EarlyView.
Okanin suppresses colorectal cancer growth by directly targeting PRDX5. This natural compound selectively binds peroxiredoxin 5 (PRDX5), inhibiting its activity and inducing WSB1‐mediated degradation. PRDX5 loss elevates ROS, suppresses GPX4 via SIAH2, and further triggers cell death (apoptosis and ferroptosis).

A Two‐Protein Chemoreceptor Complex Regulates Oxygen Thresholds in Bacterial Magneto‐Aerotaxis

Advanced Science, EarlyView.
Magnetotactic bacteria align with Earth's magnetic field, helping them migrate toward low‐oxygen environments. This study reveals how Magnetospirillum gryphiswaldense uses a specialized flavin adenine dinucleotide (FAD)‐dependent chemoreceptor, composed of two interacting proteins, for precise navigation in oxygen gradients.

Aging and the Spectral Properties of Brain Hemodynamics

Advanced Science, EarlyView.
As the brain ages, its metabolic demands decline—but not uniformly. Here, spectral slope flattening of resting‐state fMRI signals is proposed as a potential biomarker of pathologic brain aging. A subset of older adults diverges from youthful spectral and metabolic patterns, with changes linked to frontal white matter pathology and regional loss of ...

RELA Ablation Contributes to Progression of Hepatocellular Carcinoma with TP53R249S Mutation and is a Potential Therapeutic Target

Advanced Science, EarlyView.
Genome‐wide CRISPR/Cas9 based screening identified RELA as a key tumor suppressor in TP53R249S‐mutant HCC. Its loss promotes tumorigenesis and metastasis via DVL1‐mediated Wnt/β‐catenin activation, while its agonist betulinic acid suppresses tumor progression.

Topological Scaffold‐Based Trispecific Recombinant Protein‐Drug Conjugates for Solid Tumor Eradication

Advanced Science, EarlyView.
A novel tri‐specific recombinant protein and its drug conjugate are developed, named sRP‐EHI and sRPDC‐EHI, which feature a star‐shaped topological structure. It can simultaneously bind the EGFR, HER2, and integrin αvβ3 overexpressed in cancer cells.

Irisin‐Loaded Cerium‐Containing Mesoporous Bioactive Glass for Effective Immunomodulation and Odontogenesis of Dental Pulp Cells

Advanced Science, EarlyView.
The Irisin/Ce‐MBGNs delivery system can slowly release myokine Irisin for vital pulp therapy. Irisin/Ce‐MBGNs can enhance mitochondrial function and promote the differentiation of inflammatory macrophages toward M2‐Mφ, thereby regulating the immune response mechanism of inflamed dental pulp.

Targeting Neutrophil/Eosinophil Extracellular Traps by Aptamer‐Functionalized Nanosheets to Overcome Recalcitrant Inflammatory Disorders

Advanced Science, EarlyView.
In this study, C‐TAH, as multifunctional nanosheets, is developed with tannic acid and histone aptamer coverage. C‐TAH displays mild cytotoxicity, robust dsDNA and NETs/EETs binding efficiency, and potent antioxidant and antibacterial ability in vitro. C‐TAH treatment ameliorates dysregulated inflammation and restores hearing function in animal models,

Src Reduces Neutrophil Extracellular Traps Generation and Resolves Acute Organ Damage

Advanced Science, EarlyView.
Src reduces neutrophil extracellular traps (NETs) generation and resolves acute organ damage. Src directly activates RAF1 by regulating phosphorylation at the Ser 621 site and mediates the RAF/MEK/ERK pathway, thereby affecting the intracellular ROS production. Alternatively, Src activates the RAF1/MEK/ERK pathway by mediating PKC phosphorylation.
