Development of Carbon‐11 Labeled Pyrimidine Derivatives as Novel Positron Emission Tomography (PET) Agents Enabling Brain Sigma‐1 Receptor Imaging

open access: yesAdvanced Science, EarlyView.
Novel carbon‐11 labeled pyrimidine derivatives are developed as PET imaging probes for visualizing sigma‐1 receptors in the brain. [11C]CNY‐01 demonstrates superior brain uptake and binding specificity in both rodents and non‐human primates. The study reveals decreased sigma‐1 receptor expression in Alzheimer's disease, offering a promising tool for ...

Inhibiting the Histone Demethylase Kdm4a Restrains Cardiac Fibrosis After Myocardial Infarction by Promoting Autophagy in Premature Senescent Fibroblasts

open access: yesAdvanced Science, EarlyView.
Kdm4a downregulation restrains excessive cardiac interstitial fibrosis and remodeling by depressing the premature senescence of fibroblasts in the advanced stage after MI but does not affect early ventricular rupture. It verified that Kdm4a downregulation promotes autophagy in premature senescent fibroblasts by increasing the H3K9m3 modification of the

Neuronal C/EBPβ Shortens the Lifespan via Inactivating NAMPT

open access: yesAdvanced Science, EarlyView.
Schematic diagram illustrating the mechanism of shortened lifespan in Thy 1‐C/EBPβ transgenic mice and intervention strategies. Briefly, C/EBPβ/AEP escalation in the aging brain triggers NAMPT fragmentation and NAD+ depletion. Knockout of AEP from Thy 1‐C/EBPβ Tg/Tg mice ameliorates cognitive impairments and elongates the lifespan.

Tumor Microenvironment Triggered In Situ Coagulation of Supramolecularly Engineered Platelets for Precise Tumor Embolization

open access: yesAdvanced Science, EarlyView.
Occlusion of tumor blood vessels represents a promising yet challenging approach in cancer treatment. Herein, supramolecularly engineered platelets conjugated with morphology‐transformable nanoparticles is developed for precise tumor embolization. The engineered platelets actively accumulate at tumor sites following induced blood vessel injury.

Unraveling Neurodevelopment: Synergistic Effects of Intrinsic Genetic Programs and Extrinsic Environmental Cues

open access: yesAdvanced Science, EarlyView.
Overview of the regulation of intrinsic and extrinsic signals during neurodevelopment. Intrinsic genetic signals from NSCs, in conjunction with cues from microglia and blood vessels, collaboratively regulate the proliferation of NSCs, their fate determination, synaptogenesis, synaptic pruning, neuronal survival, and death, as well as communication ...

PSMD14 Stabilizes SLC7A11 to Ameliorate Glucocorticoid‐Induced Osteoporosis by Suppressing Osteocyte Ferroptosis

open access: yesAdvanced Science, EarlyView.
Glucocorticoid‐induced osteoporosis (GIOP) triggers osteocyte ferroptosis via SLC7A11 degradation. PSMD14 stabilizes SLC7A11 by counteracting glucocorticoid‐driven ubiquitination, preserving cystine uptake and glutathione synthesis. AAV‐mediated PSMD14 delivery or its agonist Pantethine rescues osteocyte survival and bone loss in GIOP mice.
