Bionic Nanostructures Create Mechanical Signals to Mediate the Composite Structural Bone Regeneration Through Multi‐System Regulation

open access: yesAdvanced Science, EarlyView.
Inspired by the structural and functional characteristics of bone, bionic nanomaterials combined with nanotechnology can more accurately replicate stem cell niches, enabling the design of bone tissue engineering scaffolds with diverse nanoscale properties to promote stem cell migration, proliferation, and differentiation. This precise control over stem

Fragment Autoantigens Stimulated T‐Cell‐Immunotherapy (FAST) as a Fast Autologous Cancer Vaccine

open access: yesAdvanced Science, EarlyView.
A personalized whole tumor cell vaccine (FAST) is developed to address immunosuppressive tumor microenvironments and genomic instability‐driven heterogeneity. Irradiation and cryoablation‐treated tumor cells generate fragmented antigens (FAs) that activate broad‐spectrum antigen presentation via upregulated immunogenic cell death, MHC‐I, and damage ...

HLA‐DR⁺ Tumor Cells Show an Association with a Distinct Immune Microenvironment and CD8⁺ T‐Cell Exhaustion in HBV‐Associated Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
This study integrates scRNA‐seq, multiplex immunofluorescence, and clinical data to identify HLA‐DR⁺tumor cells uniquely enriched in Hepatocellular carcinoma (HCC) with hepatitis B virus (HBV). These cells express MHC II, associate with PD‐L1, recruit and exhaust CD8⁺T cells, predict poor survival, and serve as potential biomarkers for immunotherapy ...

C1q+ Macrophage–Tumor Cell Interaction Promoted Tumorigenesis via GPR17/PI3K/AKT Pathway Induced DNA Hypermethylation in Nasopharyngeal Carcinoma

open access: yesAdvanced Science, EarlyView.
In the TME of NPC, C1q secreted by C1q+ TAMs interacted with GPR17 to activate PI3K/AKT signaling through strengthening GPR17 coupling PI3K and increasing calcium levels in tumor cells. The activated PI3K/AKT signaling further induces DNA hypermethylation to promote the malignancy and stemness of tumor cells.

Lipid Droplet‐Organized MDM2‐Mediated P53 Degradation: A Metabolic Switch Governing Diet‐Driven Tumor Progression

open access: yesAdvanced Science, EarlyView.
Tumor‐associated TP53 inactivation correlates with lipid droplet (LD) accumulation. High‐fat diets drive Cyb5r3‐Myh9‐mediated p53 enrichment on LD surfaces, accelerating its degradation while upregulating LD‐promoting factor CD36 expression to establish a feed‐forward loop. LD suppression or dietary intervention restores p53 and inhibits tumorigenesis,

Targeted Penetrating Motif Engineering of BH3 Mimetic: Harnessing Non‐Canonical Amino Acids for Coinhibition of MCL‐1 and BCL‐xL in Acute Myeloid Leukemia

open access: yesAdvanced Science, EarlyView.
A structure‐guided peptide derived from a non‐canonical amino acid library simultaneously targets MCL‐1 and BCL‐xL to overcome apoptotic resistance in acute myeloid leukemia. Fused with a CXCR4‐binding motif, the engineered peptide exhibits selective intracellular delivery and potent in vivo efficacy, offering a promising therapeutic strategy against ...

Inhibition of Heat Shock Protein 90β by Catalpol: A Potential Therapeutic Approach for Alleviating Inflammation‐Induced Cartilage Injuries in Osteoarthritis

open access: yesAdvanced Science, EarlyView.
The schematic diagram delineates the chondroprotective effects of Ca‐bMSN in OA models. The upper portion of the diagram depicts the synthesis process of Ca‐bMSN. The lower section illustrates the post‐injection of Ca‐bMSN in joint cavity, catalpol released and subsequently mediates the reduction of oxidative stress, ECM catabolism, apoptosis, and ...
