Lithium‐Doped Hydroxyapatite Nanowires Rejuvenate Senescent Macrophages Via the Lysosome‐Dependent Ferroptosis Axis to Promote Aged Bone Regeneration

Advanced Science, EarlyView.
Li‐nHAP+GelMA promotes mandibular bone regeneration in aged mice by remodeling the senescent immune microenvironment. Local delivery of Li‐nHAP restores lysosomal homeostasis in senescent macrophages, reduces intracellular labile Fe2+ accumulation, ROS production, and lipid peroxidation, thereby suppressing macrophage ferroptosis and senescence ...

3′‐UTR Hypermethylation and ABA Signaling Coordinate Transcriptional Activation of SWEET14 for High Sugar Accumulation in Citrus

Advanced Science, EarlyView.
Hypermethylation of CliSWEET14 3′‐UTR relieves ClibHLH105‐mediated transcriptional repression, together with ABA signaling‐mediated activation of the CliABF3‐CliNAC56 cascade, boosts CliSWEET14 expression and sucrose accumulation in citrus. ABSTRACT Sugar accumulation is pivotal for fruit quality, yet the molecular regulation of this process remains ...

Sequential Design of Activatable Photosensitizers for Ablation of Glioma Cells in Brain Cancer Tissues

Angewandte Chemie, EarlyView.
Gal‐SeNBD‐oleamide is an activatable photosensitizer (PS) with efficient uptake and selective, β‐galactosidase‐triggered activation in cancer cells, enabling efficient photodynamic ablation of glioma cells directly in brain tissue slices from mouse preclinical models and human glioblastoma patients.

Integrated Single‐Cell and Spatial Transcriptomics Reveal Convergence on a Senescence‐Associated B Cell–MIF Signaling Axis in Joint Aging and Osteoarthritis Progression

Advanced Science, EarlyView.
Single‐cell and spatial transcriptomics implicate senescent B cells and macrophage migration inhibitory factor (MIF) signaling in aging and osteoarthritic joints. An injectable hydrogel combining quercetin with siRNA targeting MIF attenuates cartilage degeneration in a mouse model of osteoarthritis.

A Bi‐Adjuvant Senolytic Nanovaccine Modulating Dendritic Cell Senescence Ameliorates Aging‐Related Metabolic Dysfunction

Advanced Science, EarlyView.
An active biomaterial‐based bi‐adjuvant nanovaccine restores the immunocompetence of aged dendritic cells to overcome senescent cell tolerance. Accompanied by the downregulation of mitotic kinases Aurka/b and attenuation of senescence‐associated PI3K/AKT phosphorylation, the nanovaccine enhances antigen‐presenting capacity and promotes potent cytotoxic

A UBE3A‐UTX Proteostasis‐Epigenetic Axis Governs Hypothalamic Energy Homeostasis

Advanced Science, EarlyView.
Ubiquitin protein ligase E3A (UBE3A) regulates hypothalamic energy homeostasis and promotes degradation of the histone demethylase UTX (KDM6A). Neuronal UBE3A loss increases susceptibility to diet‐induced obesity and is accompanied by UTX accumulation, reduced histone H3 lysine 27 trimethylation, and altered endoplasmic reticulum stress‐responsive gene

PHGDH‐Mediated Serine Metabolism in Nucleus Pulposus Cells Is a Potential Therapeutic Target for Intervertebral Disc Degeneration

Advanced Science, EarlyView.
When nucleus pulposus cells senesce, PHGDH decreases, reducing serine synthesis and glutathione, impairing antioxidant capacity. The intermediate α‐KG also drops, lowering JMJD3 demethylase activity, increasing H3K27me3 at the Rap1b promoter, and reducing Rap1b expression, whose down‐regulation in turn activates mTORC1 and suppresses autophagy ...

Blood‐Based Biomarkers in Alzheimer's Disease: Advances in Detection Technologies and Clinical Applications

AGING MEDICINE, EarlyView.
Blood‐based biomarkers are emerging as accessible tools for Alzheimer's disease screening, diagnosis, risk stratification, and longitudinal monitoring. This review summarizes major biomarkers, including Aβ42/Aβ40, phosphorylated tau species, NfL, GFAP, genetic risk markers, and exploratory inflammatory, synaptic, and proteomic candidates.

Differential Diagnosis of Mucopolysaccharidoses Types I, II, III, IVA, and VI Through Analysis of Leukocytic Inclusions

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Mucopolysaccharidoses (MPS) are lysosomal storage disorders characterized by the accumulation of glycosaminoglycans (GAGs), which can lead to cytoplasmic alterations in leukocytes. The objective of this study was to characterize leukocyte inclusions in patients with different types of MPS and assess their diagnostic relevance.
