PTG‐Dependent Glycogen Metabolic Dysfunction Drives Impaired Adipose Browning: A Novel Mechanism Linking PM2.5 to Metabolic Disorders

Advanced Science, EarlyView.
This study provides the first evidence that PM2.5 impairs iWAT browning via PTG‐mediated glycogen metabolism disruption, which is initiated by ADRB3 inhibition and subsequently triggers VEGFB upregulation. It thereby delineates the ADRB3‐PTG‐VEGFB axis as central to PM2.5‐induced metabolic dysfunction and identifies adipose glycogen metabolism as a ...

Fucosylation-Mediated Suppression of Lipid Droplet Accumulation Induced by Low-Level L-Fucose Administration in 3T3-L1 Adipocytes

Kinases and Phosphatases
Obesity causes lifestyle-related diseases such as hypertension and type 2 diabetes and has become a global health concern. L-fucose (Fuc), a monosaccharide that can be derived from brown algae, has been shown to strongly suppress lipid droplet ...

Targeting Endothelial KDM5A to Attenuate Aging and Ameliorate Age‐Associated Metabolic Abnormalities

Advanced Science, EarlyView.
This study identifies endothelial KDM5A as a key regulator of aging. KDM5A deficiency accelerates aging by enhancing H3K4me3‐mediated FABP4 expression, disrupting fatty acid metabolism, and promoting multi‐organ senescence. KDM5A restoration or FABP4 inhibition reverses these adverse effects and extends lifespan, positioning the KDM5A/FABP4 axis as a ...

Effects of Porphyromonas gingivalis Bacteria on Inflammation, Oxidative Stress and Lipid Metabolism in Models of Obese db/db Mice and 3T3-L1 Adipose Cells

Microorganisms
During periodontitis, Porphyromonas gingivalis and its lipopolysaccharides (LPS) may translocate into the bloodstream and alter adipocyte function, aggravating obesity-related disorders. This study aimed to evaluate the inflammatory and metabolic effects

⁠Engineering Adaptive Immunity in 3D: A Patient‐Specific Lymphoid Model Using Stromal Networks and Peripheral Blood Mononuclear Cells

Advanced Science, EarlyView.
This study presents a 3D lymphoid tissue model engineered from adipose‐derived stem cells differentiated into fibroblastic reticular cell–like networks and co‐cultured with immune cells. The engineered system successfully generates antigen‐specific antibodies and cytokine responses, providing a platform for studying adaptive immunity, vaccine efficacy,

WDR5‐H3K4me3 Epigenetic Axis Promotes TRMT6‐Dependent tRNA M1A Modification to Facilitate Triple‐Negative Breast Cancer Progression by Suppressing Ferroptosis

Advanced Science, EarlyView.
Upregulated TRMT6 forms aberrant hypermethylation of a specific tRNA pool and serves as a predictor of poor prognosis in TNBC. This m1A modification in tRNAs enhances translation of FTH1 and FTL, reducing the pool of bioavailable Fe2⁺. Reduced Fe2+ availability impairs RSL3‐induced lipid peroxidation and tumor progression.

A Conjugation Delivery System of Macrophages and Platelet Pharmacytes Promotes Regeneration After Spinal Cord Injury

Advanced Science, EarlyView.
A macrophage–platelet conjugation system (M‐P‐NPs@PPARγ) targets injure tissue to co‐deliver platelet mitochondria and PPARγ‐encoding NPs. This strategy boosts the macrophage energy supply and restores lipid homeostasis, leading to synergistically enhanced efferocytosis and tissue repair Abstract Mitochondrial dysfunction occurs in macrophages with ...
