Lysosome‐Featured Cell Aggregate‐Released Extracellular Vesicles Regulate Iron Homeostasis and Alleviate Post‐Irradiation Endothelial Ferroptosis for Mandibular Regeneration

open access: yesAdvanced Science, EarlyView.
Lysosomal redistribution occurs via extracellular vesicles in multi‐stem cell aggregates and controls iron homeostasis for safeguarding cell aggregation. These cell aggregate‐released extracellular vesicles (CA‐EVs) rescue lysosomal impairments and exert anti‐ferroptosis effects in recipient irradiated endothelial cells.

Contribution of Prostaglandin E2‐Induced Neuronal Excitation to Drug Resistance in Glioblastoma Countered by a Novel Blood–Brain Barrier Crossing Celecoxib Derivative

open access: yesAdvanced Science, EarlyView.
Glioblastoma (GBM) is an aggressive brain cancer that often recurs and resists chemotherapy. This study found that a chemical called PGE2 causes surrounding brain cells (neurons) to become over‐excited, which makes GBM cells resistant to treatment. Researchers developed a new drug, “Compound 11,” which can cross into the brain and effectively block ...

An Atomically Dispersed Photocatalyst for Undirected para‐Selective C─H Bond Functionalizations

open access: yesAngewandte Chemie, EarlyView.
This study presents an atomically dispersed recyclable heterogeneous photocatalytic method for para‐selective trifluoromethylation of electron‐deficient arenes without directing groups. Unlike previous substrate‐dependent approaches, this recyclable, atomically dispersed photocatalyst enables scalable synthesis of bioactive trifluoromethylated ...

Molecular Identification of Cytosolic Prostaglandin E2 Synthase That Is Functionally Coupled with Cyclooxygenase-1 in Immediate Prostaglandin E2Biosynthesis*

open access: yesJournal of Biological Chemistry, 2000
Here we report the molecular identification of cytosolic glutathione (GSH)-dependent prostaglandin (PG) E2 synthase (cPGES), a terminal enzyme of the cyclooxygenase (COX)-1-mediated PGE2 biosynthetic pathway. GSH-dependent PGES activity in the cytosol of

Half‐Pipe Melt Electrowritten Scaffolds Support Engineering of an Immunocompetent Hydrogel‐Embedded Intestine‐on‐a‐Chip

open access: yesAdvanced Science, EarlyView.
The immunocompetent Intestine‐on‐a‐Chip (IoC) is developed using melt electrowritten (MEW) half‐pipes. Intestinal epithelial cell (IEC) culture is optimized in the MEW‐based IoC, followed by co‐culture with monocyte‐derived dendritic cells (moDCs) and T cells in 3D hydrogels.

Tendon Aging: A Silent Enemy Revealed Strategies for Effective Treatment

open access: yesAGING MEDICINE, EarlyView.
This review commences with the mechanism of tendon aging, mainly introducing the aging of tendons induced by oxidative stress, hyperglycemia, inflammatory response, cell apoptosis, and fatty infiltration and the association with the tendon stem/progenitor cells, aiming to explore the mechanism of aging and find related treatment methods.
