Adipocytes Promote Cisplatin Resistance through Secreting A1BG and Regulating NAMPT/PARP1 Axis‐Mediated DNA Repair in Osteosarcoma

open access: yesAdvanced Science, EarlyView.
The proposed working model for how adipocytes participate in cisplatin resistance in osteosarcoma. The adipocytes secret A1BG and stabilize NAMPT, leading to increased NAD⁺ levels and subsequent increased PARP1‐mediated DNA repair, resulting in cisplatin resistance in osteosarcoma finally.

Macrophage‐Mediated Transport of Insoluble Indirubin Induces Hepatic Injury During Intestinal Inflammation

open access: yesAdvanced Science, EarlyView.
Plant‐derived bioactive molecules with low solubility and permeability induce hepatocyte injury, though the mechanisms driving their hepatic effects remain poorly understood. This study identifies a novel transport pathway in which poorly soluble indirubin accumulates in the liver via macrophage‐mediated uptake in Peyer's patches, exacerbating hepatic ...

Parvalbumin Interneuron‐Dependent Hippocampal Neurogenesis Evoked by Prolonged Rhythmic Light Flicker

open access: yesAdvanced Science, EarlyView.
This study demonstrates that prolonged rhythmic 40 Hz light flicker enhances spatial learning by stimulating PV interneuron‐dependent neurogenesis. The light flicker selectively activates PV interneurons, which enhances GABAergic support for the integration of immature neurons in the adult dentate gyrus.

Splicing Shift of RAC1 Accelerates Tumorigenesis and Defines a Potent Therapeutic Target in Lung Cancer

open access: yesAdvanced Science, EarlyView.
Dysregulated RNA splicing is an underappreciated molecular feature of cancer. By integrating murine and cellular models with patient specimens of lung adenocarcinoma, this study demonstrates that RAC1B, rather than RAC1A isoform, promotes tumorigenesis and presents a potent therapeutic target for lung cancer. Mechanistically, RAC1B preferentially binds

Nanoscale Metal‐Organic Framework‐Based Self‐Monitoring Oxygen Economizer and ROS Amplifier for Enhanced Radiotherapy‐Radiodynamic Therapy

open access: yesAdvanced Science, EarlyView.
A Fe (III)–Pt (II) porphyrin framework‐based radiosensitizer (FPTM‐LP) is constructed to serve as an oxygen economizer, hypoxia self‐monitoring device, and reactive oxygen species (ROS) amplifier. The glutathione (GSH)/pH‐responsive release of lonidamine achieves oxygen‐economization to combat hypoxia‐induced radioresistance guided by near infrared ...

Cellular Adaptation to Mechanical Stress Emerges via Cell Shrinkage Triggered by Nonlinear Calcium Elevation

open access: yesAdvanced Science, EarlyView.
Here, a decision‐making mechanism underlying mechanical adaptation is demonstrated. This study demonstrates that cellular adaptation to mechanical stress can be induced by applying low‐amplitude stretch to cells. When the stretch reaches a critical amplitude threshold, it triggers Ca2⁺‐dependent positive feedback, which induces cholesterol efflux and ...

Neutrophil Mobilization Triggers Microglial Functional Change to Exacerbate Cerebral Ischemia‐Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
These study underscores the pivotal role of neutrophil‐derived myeloid‐related protein 14 (MRP14) in the pathophysiology of acute ischemic stroke (AIS). MRP14 not only disrupts mitochondrial function, thereby inhibiting microglial phagocytosis of neutrophils, but also activates microglial pyroptosis, exacerbating neuroinflammation following AIS ...

USP8‐Governed MDA5 Homeostasis Promotes Innate Immunity and Autoimmunity

open access: yesAdvanced Science, EarlyView.
This study reveals that USP8 stabilizes MDA5 via AKT‐mediated phosphorylation (Ser718), enhancing their interaction and MDA5 deubiquitination. USP8 inactivation degrades MDA5, suppressing type I IFN and cytokine production. Pharmacological inhibition of USP8/AKT alleviates MDA5‐driven autoimmunity, demonstrating the USP8‐MDA5 axis as a therapeutic ...
