Mn/Zn Bimetallic MOF‐Integrated Hydrogel Alleviates Excessive Mitochondrial Fission in BMSCs to Promote Osteoporotic Jawbone Repair

open access: yesAdvanced Science, EarlyView.
Excessive reactive oxygen species (ROS) and chronic inflammation impair bone marrow‐derived mesenchymal stem cells (BMSCs), contributing to poor healing in osteoporotic jawbone defect. The gelatin methacryloyl hydrogel loaded with manganese‐doped zeolitic imidazolate framework (Mn‐ZIF‐8@GelMA) promotes regeneration through redox regulation and ...

Loss of Intestinal MSTN Promotes GLP‐1 Secretion Through SGLT1 Palmitoylation

open access: yesAdvanced Science, EarlyView.
Intestinal MSTN deficiency enhances glucose‐stimulated GLP‐1 secretion and glucose tolerance in high‐fat diet‐fed mice. Mechanistically, loss of MSTN promotes YY1‐associated ZDHHC20 expression, increasing SGLT1 S‐palmitoylation at Cys301 and its plasma membrane localization in L cells.

Proline-rich tyrosine kinase 2 mediates gonadotropin-releasing hormone signaling to a specific extracellularly regulated kinase-sensitive transcriptional locus in the luteinizing hormone beta-subunit gene [PDF]

open access: yes, 2007
G protein-coupled receptor regulation of gene transcription primarily occurs through the phosphorylation of transcription factors by MAPKs. This requires transduction of an activating signal via scaffold proteins that can ultimately determine the outcome

Precision Nanomedicine for Traumatic Neural Injury: Functional Paradigms and Translational Frameworks

open access: yesAdvanced Science, EarlyView.
This review presents a pathology‐driven framework unifying nanomedicine across TBI, SCI, and PNI. Epidemiological evidence and comparative single‐cell transcriptomic reanalysis define shared pathological modules, injury‐specific effectors, and therapeutic bottlenecks. Six functional paradigms connect nanomaterial structure and biological fate to injury‐

The type III pseudomonal exotoxin U activates the c-JUN NH2-terminal kinase pathway and increases human epithelial interleukin-8 production

open access: yes, 2006
Microbial interactions with host cell signaling pathways are key determinants of the host cell response to infection. Many toxins secreted by bacterial type III secretion systems either stimulate or inhibit the host inflammatory response. We investigated

Acinar‐Derived Organoids Reveal Stage‐Specific Control of Acinar Plasticity

open access: yesAdvanced Science, EarlyView.
An acinar‐derived organoid system maintains adult pancreatic acinar identity ex vivo, converts it along an ordered acinar‐to‐ductal‐like trajectory, and then partially restores it. Each transition carries its own signal requirement, with EGF/EGFR initiating conversion and a staged glucocorticoid–IGF1R switch driving redifferentiation.

Hepatocyte CBX2 Safeguards Hepatic Lipid Homeostasis by Elevating Ca2+‐CaMKK2‐AMPK Signaling to Counter MASLD

open access: yesAdvanced Science, EarlyView.
In hepatocytes, CBX2 promotes H3K4me3 enrichment at the Orai1 promoter to enhance Orai1 transcriptional activation, thereby increasing intracellular Ca2+ levels. The elevated Ca2+ activates the CaMKK2‐AMPK signaling cascade, resulting in ACC phosphorylation and downstream metabolic regulation. This cascade suppresses de novo lipogenesis (Fasn, Acc, Scd‐

The Novel Viral Non‐Coding RNA LMP2A‐IT1 Promotes the Lytic Replication of EBV

open access: yesAdvanced Science, EarlyView.
Decades after its discovery, EBV's genome still harbours unannotated “dark matter”. LMP2A‐IT1, a novel EBV‐encoded transcript identified in this work, is strongly upregulated during lytic replication and promotes BZLF1 expression, likely through activation of inflammatory responses, thereby enhancing viral propagation in a self‐reinforcing positive ...

Stage‐Adaptive Bilayer Hydrogel Coordinates Photodynamic Antibacterial Therapy with Engineered Extracellular Vesicle–Mediated Immunomodulation in Infected Diabetic Wounds

open access: yesAdvanced Science, EarlyView.
Early photodynamic infection control and subsequent immunoregulatory repair are spatially separated within a stage‐adaptive bilayer hydrogel. Chlorin e6 is incorporated into the wound‐contacting layer to provide light‐triggered bactericidal therapy, whereas the upper layer regulates excessive reactive oxygen species before releasing microRNA‐146a ...
