SuFEx‐Enabled Reprogramming of Flavonoids for Selective α‐Glucosidase Covalent Inhibition

Advanced Science, EarlyView.
Selective inhibition of intestinal α‐glucosidase remains limited by poor enzyme specificity and off‐target metabolic effects. Here, SuFEx click chemistry is used to reprogram natural flavonoids into covalent inhibitors with enhanced α‐glucosidase selectivity and controlled reactivity. This strategy enables effective regulation of carbohydrate digestion

NMI Regulates Adipose Adaptive Thermogenesis Through TLR4/IRF3 Signaling to Promote Obesity

Advanced Science, EarlyView.
Adipose tissue‐derived NMI is secreted under metabolic stress and suppresses adaptive thermogenesis through TLR4/IRF3 signaling, repressing the PPARα/PGC‐1α/UCP1 thermogenic transcriptional program. Genetic ablation or anti ‐ NMI monoclonal antibody treatment enhances energy expenditure, protects against DIO, and ameliorates adipose tissue inflammation,

A Wireless 3D Magneto‐Mechanical Stimulation Platform Drives In Situ Chondrogenic Commitment of Endogenous MSCs

Advanced Science, EarlyView.
An intracellular magneto‐mechanical platform utilizing MSC‐targeted nanomotors is developed. After intra‐articular delivery, these nanomotors target endogenous BMSCs and are actuated within lysosomes to execute trans‐planar rotational‐bouncing motions under a rotating‐fluctuating 3D magnetic field, generating amplified mechanical stimulation.

Hemoglobin's α‐Helix‐to‐β‐Sheet Transition Enables Targeted mRNA Delivery to the Lung

Advanced Science, EarlyView.
Acidic heating converts hemoglobin into β‐sheet‐rich fibrils with positively charged surfaces. These hemoglobin fibrils electrostatically complex IL‐11 scFv mRNA, selectively bind circulating platelets, and hitchhike to the lung, where they are enriched in fibroblasts.

T2T Genome Assembly and Multi‐Omics Data Reveal Terrestrial Adaptation and Mucus Biosynthesis in Tropical Leatherleaf Slug (Laevicaulis alte)

Advanced Science, EarlyView.
A gap‐free genome assembly and multi‐omics comparison of the terrestrial slug Laevichaulis alte with an aquatic relative reveal that expansion of the VEGF family orchestrates mucus production, lipid metabolism, and immune defense—highlighting key molecular innovations for conquering life on land.

Insulin Clearance Along the Liver–Kidney Axis: Implications for Insulin Action

Metabolites
The pleiotropic actions of insulin are mediated by cascades of signaling pathways and are regulated by circulating insulin levels. Under physiologic conditions, insulin levels reflect the balance between pancreatic beta-cell secretion and insulin ...

Inhibition of KDEL Receptors Remodels the Tumor Microenvironment for T Cell Independent Tumor Regression

Advanced Science, EarlyView.
Inhibition of KDELR2 in a small fraction of tumor cells generates sustainable immunogenic cell death conditions within the tumor microenvironment. These conditions promote the regression of tumors in a T cell independent manner. During regression, macrophages prime T cells that subsequently provide systemic protection against recurrence. The potency of

Human Urine Stem Cells Alleviate Pulmonary Fibrosis via Inhibiting Macrophage‐Myofibroblast Transition

Advanced Science, EarlyView.
Therapeutic role and mechanism of human urine stem cells (hUSCs) in pulmonary fibrosis. hUSCs alleviated pulmonary fibrosis by selectively inhibiting macrophage‐myofibroblast transition (MMT) in two ways: on one hand, hUSCs inhibited mitochondrial reactive oxygen species (mtROS) production and apoptosis/senescence of epithelial cells in pulmonary ...

Condition‐Associated Pattern Extraction and Recovery From Multi‐Condition Single‐Cell RNA‐seq Data With CAPER

Advanced Science, EarlyView.
Decoupling biological signals from unwanted variation in multi‑condition single‑cell RNA sequencing data remains challenging. CAPER disentangles condition‑associated biological effects from sample heterogeneity through matrix factorization, producing interpretable latent factors and a batch‑corrected expression matrix.

Adipocyte Myoglobin Is a Determinant of Energy Expenditure and a Potential Target to Limit Obesity

Advanced Science, EarlyView.
Myoglobin, known as a muscle oxygen‐carrying protein, is shown to play a key role in fat cells that burn energy. Loss of myoglobin reduces the body's ability to generate heat and increases obesity risk, while restoring it improves metabolism. The study identifies myoglobin as a regulator of fat burning and a potential target to enhance energy ...
