Deciphering Anti‐Cancer Drug Efficacy Through Nanomechanical Vibrations in Living Gastric Cancer Organoids

open access: yesAdvanced Science, EarlyView.
This study developed an efficacy assessment platform that integrates patient‐derived gastric cancer organoids, atomic force microscopy (AFM)‐based nanomechanical vibration detection, deep learning analysis, and organoid mechanical modeling. It detects picomolar drug effects within 0.1 s signal, achieves 97% classification accuracy, and offers non ...

SDF‐1 Attenuates Oocyte Quality Decline During Reproductive Aging Through Autophagy‐Enhanced Stress Granule Scavenging

open access: yesAdvanced Science, EarlyView.
SDF‐1 levels decline significantly with maternal aging. Exogenous supplementation restores meiotic spindle morphology, chromosomal alignment, and mitochondrial function while reducing oxidative stress in aged oocytes. Mechanistically, SDF‐1 enhances autophagic activity to clear accumulated stress granules, thereby rescuing fertilization competence and ...

Informe final del proyecto: Rol de mitocondria en la secreción de vesículas extracelulares por células senescentes

open access: yes
Las células pueden entrar en un estado llamado senescencia celular, en el cual dejan de dividirse, pero continúan activas metabólicamente y liberan diversas señales hacia su entorno.

USP5 Stabilizes TGFBR1 to Drive Vascular Smooth Muscle Cell Senescence and Atherosclerosis

open access: yesAdvanced Science, EarlyView.
This study reveals that USP5 drives vascular smooth muscle cell senescence and atherosclerosis by stabilizing TGFBR1, suppressing IDH2, and promoting glycolytic reprogramming, identifying the USP5‐TGFBR1‐IDH2 axis as a potential therapeutic target. ABSTRACT Vascular smooth muscle cell (VSMC) senescence contributes importantly to atherosclerotic plaque ...

In Situ Programmable Modulation of Hydrogel Stiffness for Stage‐Adaptive Bone Regeneration

open access: yesAdvanced Science, EarlyView.
Near‐infrared (NIR) irradiation triggers Ca2+ release from thermoresponsive nanocarriers, enabling in situ stiffening of an adaptive hydrogel from a soft to a stiff state, thereby sequentially supporting mesenchymal stromal cell stemness and osteogenic differentiation for stage‐adaptive bone regeneration.

Fibrillarin Resists Cellular Senescence Via SIRT1‐Dependent Nicotinamide Metabolism and Its Inhibition Sensitizes Senolytic Therapy in Esophageal Squamous Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
FBL directly binds to and stabilizes SIRT1 by blocking its ubiquitin‐proteasome degradation, thereby sustaining nicotinamide metabolism and redox homeostasis to counteract cellular senescence in ESCC. Genetic and pharmacological suppression of FBL sensitizes tumor cells to senolytic therapy.
