Cell Contractile Force‐Mediated Morphogenetic Tissue Engineering via 4D Printed Degradable Hydrogel Scaffolds

Advanced Science, EarlyView.
Through the actuation of cell contractile forces, geometrically complex structures are formed via a bioprinted, rapidly degrading cell‐laden hydrogel system, resulting in cell‐only condensation within a few days of culture. This system supports stem cell differentiation down different lineages and new tissue formation, such as chondrogenesis and ...

Amphiregulin and Epiregulin Confer Radioresistance in Esophageal Squamous Cell Carcinoma Through Oxidative Phosphorylation

Advanced Science, EarlyView.
Oxidative phosphorylation (OXPHOS) activity serves as a critical metabolic determinant of radiotherapy outcomes in esophageal squamous cell carcinoma (ESCC). The CEBPB/AREG/EREG axis drives radioresistance in ESCC by reprogramming OXPHOS. AREG and EREG function as predictive biomarkers for nCRT response and prognosis of ESCC patients.

Morphine Tolerance Gated through EZH2‐Mediated Suppression of Trpc5 in Spinal GABAergic Interneurons in Male Mice

Advanced Science, EarlyView.
Chronic morphine suppresses Trpc5 in spinal GABAergic interneurons via EZH2‐mediated histone modification, reducing Ca2+ influx and GABA release. TRPC5 activation enhances morphine analgesia, while EZH2 inhibition restores efficacy and reverses tolerance.

HPD is an m6A Methyltransferase that Protects Colorectal Cancer Cells from Ferroptotic Cell Death by m6A Methylating SLC7A11/GPX4

Advanced Science, EarlyView.
This study reveals that the tyrosine metabolic enzyme HPD functions as a previously uncharacterized, METTL3‐independent m6A methyltransferase. It promotes colorectal tumor progression by coordinately regulating the SLC7A11/GPX4 axis to suppress ferroptosis.
