Laser Ultrasound Super‐Resolution Imaging for Multi‐Parametric Non‐Invasive Volumetric Characterization of Brain Cancer

open access: yesAdvanced Science, EarlyView.
Laser ultrasound super‐resolution imaging (LUSSI) leverages laser‐generated ultrasound for functional 3D transcranial imaging of brain tumor vasculature. Combined with optoacoustic tomography, it is demonstrated in a glioblastoma model, revealing structural abnormalities, compressed vessels, hemorrhages, and hypoxic regions.

Ultrasound‐Mediated Biotransfection of Engineered Bone Marrow Mesenchymal Stem Cells in Treated Bone Defects through Intracellular Cavitation

open access: yesAdvanced Science, EarlyView.
Ultrasound‐mediated biotransfection through intracellular cavitation increases plasmid nuclear translocation and gene transfection efficiency by 284.7% and 131.6% in engineered bone marrow mesenchymal stem cells (BMSCs) compared to traditional ultrasound‐targeted microbubble destruction techniques. The maintained bone morphogenetic protein 2 expression

Strategic Design of Aptamer‐Guided Aggregation‐Induced Emission Nanoparticles for Targeted Photodynamic Therapy in Breast Cancer

open access: yesAdvanced Science, EarlyView.
This study presents MF3Ec‐TBPP nanoparticles for targeted photodynamic therapy of Luminal A breast cancer. These nanoparticles combine an AIE‐based photosensitizer with an aptamer. Tests show they effectively inhibit tumor growth while protecting healthy tissue via aggregation and dipalmitoylphosphatidylcholine, indicating potential for improved ...

Optimized Monothiol Thioredoxin Derivative (ORP100S) Protects In Vitro and In Vivo from Radiation and Chemotoxicity Without Promoting Tumor Proliferation

open access: yesAdvanced Science, EarlyView.
Native thioredoxin‐1 (TRX) stimulates proliferation and rescues stem cells and cancer cells from multiple stressors by suppressing p53 and inhibiting ferroptosis via GPX4/SLC7A11 upregulation mediated by enhanced KLF4 expression and p53 promoter binding.

Acidosis Forces Fatty Acid Uptake and Metabolism in Cancer Cells Regardless of Genotype

open access: yesAdvanced Science, EarlyView.
This study demonstrates that biological acidosis, commonly observed in tumors and ischemic conditions, actively promotes the protonation of fatty acids, thereby facilitating the uptake of their neutral forms. Consequently, the preference for lipid metabolism in acid‐exposed cells does not arise from genetic reprogramming that prioritizes lipids as the ...
