Atrophic Skeletal Muscle‐Derived Extracellular Vesicles Transfer miR‐125a‐5p to Inhibit Bone Formation in Osteoporosis during Aging

open access: yesAdvanced Science, EarlyView.
A muscle‐bone endocrine pathway in aging is revealed in which extracellular vesicles released from atrophic skeletal muscle (Aged‐SKM‐EVs) inhibit bone formation. These EVs deliver miR‐125a‐5p to osteoblasts, thereby suppressing the SIRT7‐Sp7 signaling axis and osteogenic differentiation.

VE‐Cadherin–Actin Regulation Promotes Mechanotransduction and Monolayer Maturation Involving a Tension‐Sensitive Intermediate State

open access: yesAdvanced Science, EarlyView.
This study investigates how endothelial monolayers balance cohesion and plasticity during mechanical stimulation. In HUVECs, shear stress induces a tension‐sensitive intermediate state in which junctional VE‐cadherin and actomyosin relaxation levels coordinate actin/integrin remodeling. This rapid, reversible state strengthens cell junctions, preserves

USP35 Acts as a Deubiquitinating Enzyme for ID3 to Promote Immune Escape in Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
USP35 stabilizes ID3 expression by deubiquitinating the K2/K30 site, thereby upregulating PD‐L1 and promoting immune escape in colorectal cancer. IU1, an inhibitor of USP35 enzyme activity, has been shown to inhibit USP35, thereby accelerating ID3 degradation, enhancing CD8+ T cell killing, and reversing the immunosuppressive microenvironment ...

Non‐Targeting shRNA‐Encoded Plasmid DNA Enhances Protective Immunity Through RIDD‐RIG‐I Signaling Pathway in the Zika Virus Animal Model

open access: yesAdvanced Science, EarlyView.
We present a novel DNA vaccine platform featuring intrinsic, non‐targeting dsRNA that significantly enhances immune responses by activating the regulated IRE1‐dependent decay‐RIG‐I signaling pathway. This research elucidates a previously uncharacterized mechanism for dsRNA‐mediated innate immune activation.

Pan2‐Pan3 Complex‐Mediated Deadenylation Enforces mRNA Quality Control for Infection of the Rice Blast Fungus

open access: yesAdvanced Science, EarlyView.
Discovery that deadenylation, rather than transcription, acts as the rate‐limiting step for developmental timing in a plant pathogen. Evidence that P‐body integrity and mRNA decay are mechanistically coupled to rapid cellular differentiation under environmental stress. Identification of Pan2‐Pan3 as a pathogen‐specific “meta‐virulence factor” absent in

Gastrocnemius Neuromuscular Activation During Standing Explosive Acceleration

open access: yesLife
The gastrocnemius muscle plays a crucial role in transmitting and generating energy during standing explosive accelerations, and as a consequence, is a muscle with high injury prevalence, especially the medial gastrocnemius (MG).

Ce‐Doped Lignin‐Based Nanozyme with Heat‐Activated Hydrolase Activity

open access: yesAdvanced Science, EarlyView.
A novel Ce‐doped lignin‐based hydrolase nanozyme (Ce‐AL) is synthesized using Ce ions coordinated with aminated industrial lignin. The Ce‐AL effectively hydrolyzes phosphate ester bonds and protein amide bonds, maintain high activity at 100°C, and successfully fights bacteria biofilms.

Cross‐Platform Biosensing of Immune Receptors Using Peptide‐Functionalized Graphene

open access: yesAdvanced Science, EarlyView.
A peptide‐functionalized graphene biosensor enables sensitive and selective detection of living immune cells. Targeting Formyl‐Peptide Receptor 2 (FPR2), the assay is demonstrated on model cells and primary human neutrophils. The same assay is applied to two complementary platforms: graphene‐enhanced surface plasmon resonance for optical benchmarking ...

Selenoprotein H Functions as a PPARα Coactivator to Link Selenium Homeostasis to Hepatic Lipid Metabolism and Protect against Steatohepatitis

open access: yesAdvanced Science, EarlyView.
Our study identifies selenium deficiency as a hallmark of MASH pathogenesis. Dietary selenium supplementation enhances hepatic fatty acid oxidation (FAO) and attenuates MASH progression by activating the PPARα pathway via selenoprotein H (SELENOH). This selenium‐SELENOH‐PPARα nexus redefines the functional scope of selenoproteins, moving from redox ...

ZBTB21 Is a Dual Suppressor of Pyroptosis and MHC‐I Antigen Presentation That Promotes Tumor Immune Evasion

open access: yesAdvanced Science, EarlyView.
ZBTB21 is a transcription factor that epigenetically suppresses pyroptosis and MHC‐I antigen presentation, enabling tumor immune evasion. Genetic ablation of ZBTB21 activates pyroptotic cell death and enhances antigen presentation, recruiting CD8+ T cells to overcome immune checkpoint blockade resistance.
