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.

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.

MeCP2 Lactylation Protects against Ischemic Brain Injury by Transcriptionally Regulating Neuronal Apoptosis

open access: yesAdvanced Science, EarlyView.
MeCP2 lactylation protects against ischemic stroke by reducing brain infarct volume and improving neurological outcomes. Lactylation at K210/K249 exerts neuroprotective effects by repressing the transcription of apoptosis‐associated genes, including Pdcd4 and Pla2g6. HDAC3 and p300 serve as key regulatory enzymes for MeCP2 lactylation following stroke.

Diallyl Trisulfide From Garlic Regulates RAB18 Phase Separation to Inhibit Lipophagy and Induce Cuproptosis in Hepatic Stellate Cells for Antifibrotic Effects

open access: yesAdvanced Science, EarlyView.
Diallyl trisulfides (DATs) selectively induce cuproptosis in hepatic stellate cells (HSCs) by targeting Ras‐related protein Rab‐18 (RAB18) and regulating lipophagy. DATs promote RAB18 phase separation, enhance mitochondrial‐associated membrane structures (MAMs) formation, and increase succinylation of dihydrolipoamide dehydrogenase (DLD) at K320.

Targeted Delivery of α‐ketoglutarate to Macrophages in Bone: A Novel Therapeutic Strategy for Improving Fracture Healing in Type 2 Diabetes

open access: yesAdvanced Science, EarlyView.
The study reveals that glutaminolysis in macrophages is inhibited under type 2 diabetes mellitus (T2DM) conditions, which impedes fracture healing by reducing bone morphogenetic protein 2 (BMP2) production through increased cytosine methylation on the promoter.

The Lung Microbiome Modulates Pain‐Like Behavior Via the Lung–Brain Axis in a Nitroglycerin‐Induced Chronic Migraine Mouse Model

open access: yesAdvanced Science, EarlyView.
Intratracheal neomycin alters pulmonary microbiota, activating the vagus nerve via lung brain‐derived neurotrophic factor/tropomyosin receptor kinase B (BDNF/TrkB) pathway, further projecting to nucleus of solitary tract (NTS), then dorsal raphe nucleus (DRN), where activated serotoninergic neurons increase brain serotonin, alleviating migraine.

Inhibition of Ferroptosis Delays Aging and Extends Healthspan Across Multiple Species

open access: yesAdvanced Science, EarlyView.
This study identifies ferroptosis as a key driver of cellular senescence, with its inhibition delaying aging and extending healthspan across species. During senescence, ferroptosis worsens, increasing oxidative stress and lipid peroxidation, which accelerate aging.

Chromosome‐Level Genome Assembly of the Leafcutter Bee Megachile rotundata Reveals Its Ecological Adaptation and Pollination Biology

open access: yesAdvanced Science, EarlyView.
The genome of Megachile rotundata, an extensively managed solitary pollination bee species, has been sequenced, covering 280.68 Mb and predicting 10 701 genes. The study reveals significant expansions of the Toll gene family and their abundant expression in diapause prepupae, highlighting enhanced immune responses during diapause. This genome serves as

Reversible High‐Affinity Binding of Coagulation Factor Xa to Zeolites Induces Accelerated Blood Coagulation

open access: yesAdvanced Science, EarlyView.
A calcium‐dependent, specific biorecognition between coagulation factor Xa (FXa) and zeolite is discovered. It alters the prothrombin activation pathway to a more efficient mechanism by mimicking the FXa/factor Va (FXa/FVa) interaction formed during the natural coagulation cascade.
