Mutual regulation of HIF-1α and circ-UBE2G1 under hypoxic microenvironment promotes thyroid cancer metastasis

open access: yes陆军军医大学学报
Objective To investigate the mechanism by which hypoxia-inducible factor (HIF)-1α and circ-UBE2G1 mutually regulate and promote thyroid cancer (THCA) metastasis under hypoxic microenvironment.

FOS3D: A Fluorescence‐Enabled Toolkit for Characterizing a Three‐dimensional Osteosarcoma Model

open access: yesAdvanced Science, EarlyView.
FOS3D describes fluorescent (F) osteosarcoma (OS) cells in a tri‐dimensional (3D) model. The study comprises three phases: development, where biofabrication parameters are tuned to achieve cytocompatibility and tumor‐specific mechanical properties in cell‐laden gelatin methacryloyl constructs; validation, where whole‐well fluorescence reading is ...

Intrinsically Mitochondria‐Targeting Nanozyme via Coordination‐Assembly of Natural Quercetin for Cascade Antioxidant Therapy of Cerebral Ischemia‐Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
This study uncovers that quercetin naturally targets mitochondria. By coordinating quercetin with Fe3+, we engineer an ultrasmall cascade nanozyme (MCN) with superoxide dismutase‐catalase activities. MCN crosses the damaged blood–brain barrier, scavenges mitochondrial ROS, prevents mitochondrial DNA leakage, and blocks the cGAS‐STING pathway, thereby ...

ELR510444 decreases HIF-1α and HIF-2α expression.

open access: yes, 2013
(A) ELR510444 (chemical structure on left) inhibits HIF-1α activity. RCC4 cells were treated with the indicated concentrations of ELR510444 for 16 h. Cells were harvested, nuclei isolated and lysed, and HIF-1α activity was measured using a commercial ...

Micro‐Galvanic Coupling Programs the Therapeutic Zinc Ion Window to Reconfigure Immune Cascades for Pro‐Regenerative Bone Healing

open access: yesAdvanced Science, EarlyView.
This study utilized alloy micro‐galvanic coupling design to regulate the release of essential elements, thereby programming immune responses and promoting regeneration. The sacrificial anodic process of Zn‐0.8Mg reduced Zn2+ release compared to the “large cathode‐small anode” coupling of Zn‐0.8Fe.

Spatiotemporal Targeting Randle Cycle and Immune Checkpoint for Potent Antitumor Therapy

open access: yesAdvanced Science, EarlyView.
A glucose oxidase‐based nanogel (GOX‐NG) system using catechol‐functionalized alginate, exhibits enhanced tumor penetration, prolonged retention, and sustained glucose depletion in the tumor microenvironment. When combined with a fatty acid oxidation inhibitor, it implements dual metabolic suppression, thereby enhancing ROS‐induced immunogenic cell ...

Hypoxia and the endometrium: An indispensable role for HIF-1α as therapeutic strategies

open access: yesRedox Biology
Hypoxia-inducible factor 1 alpha (HIF-1α) is a major molecular mediator of the hypoxic response. In the endometrium, local hypoxic conditions induced by hormonal fluctuations and endometrial vascular remodeling contribute to the production of HIF-1α ...
