Ufmylation‐Deficient DDRGK1 Ameliorates Obesity by Inhibiting FASN‐Mediated Adipocyte Lipogenesis

open access: yesAdvanced Science, EarlyView.
DDRGK1 regulates de novo lipogenesis via stabilization of fatty acid synthase (FASN). DDRGK1‐mediated UFMylation of FASN prevents its ubiquitin–proteasomal degradation. Reduced DDRGK1 expression or mutation at the key UFMylation site enhances FASN degradation and suppresses fatty acid synthesis (FAS), resulting in smaller adipocytes and improved ...

Atrophic Skeletal Muscle‐Derived Extracellular Vesicles Transfer miR‐125a‐5p to Inhibit Bone Formation in Osteoporosis during Aging

open access: yesAdvanced Science, EarlyView.
A muscle‐bone endocrine pathway in aging is revealed in which extracellular vesicles released from atrophic skeletal muscle (Aged‐SKM‐EVs) inhibit bone formation. These EVs deliver miR‐125a‐5p to osteoblasts, thereby suppressing the SIRT7‐Sp7 signaling axis and osteogenic differentiation.

HSP90AB1‐Mediated Ubiquitin‐Proteasome Degradation of ITGBL1 Promotes Osteosarcoma Progression by Inhibiting Endoplasmic Reticulum Stress‐Induced Autophagy

open access: yesAdvanced Science, EarlyView.
This study delineates a novel HSP90AB1‐ITGBL1 signaling axis governing osteosarcoma. HSP90AB1 promotes K63‐linked ubiquitination and proteasomal degradation of ITGBL1. Restoring ITGBL1 induces reactive oxygen species‐dependent endoplasmic reticulum stress and pro‐death autophagy, suppressing tumor growth and metastasis.

Radical‐Mediated, Substrate‐Independent Fabrication of Hybrid Solid–Hydrogel Materials With Tunable Crosslinking: An Initiator‐ and Crosslinker‐Free Approach

open access: yesAdvanced Science, EarlyView.
This work introduces a substrate‐independent, reagent‐free plasma strategy that forms radical‐rich interlayers for covalent hydrogel attachment without initiators or crosslinkers. The long‐lived radicals drive in situ gelation, creating robust, cytocompatible hybrid solid–hydrogel constructs across diverse substrates.

Variability in the reported management of pulmonary metastases in osteosarcoma. [PDF]

open access: yes, 2015
Nearly 20% of patients with newly diagnosed osteosarcoma have detectable metastases at diagnosis; the majority of which occur in the lungs. There are no established recommendations for the timing and modality of metastasectomy.

Single‐Cell Atlas of Subchondral Bone Marrow Lesions Reveals Proteostasis Dysfunction as a Druggable Mechanism for Early Osteoarthritis

open access: yesAdvanced Science, EarlyView.
This study reveals that abnormal mechanical stress downregulates the expression of HSP70 and impairs proteasome function in osteoarthritic bone cells, leading to misfolded collagen I accumulation and ER stress. When intracellular proteostasis capacity is exceeded, USP19 mediates the secretion of misfolded proteins into the extracellular space ...

Single‐Cell Mitochondrial Lineage Tracing Decodes Fate Decision and Spatial Clonal Architecture in Human Hematopoietic Organoids

open access: yesAdvanced Science, EarlyView.
This study repurposes mitochondrial DNA mutations as endogenous barcodes for lineage tracing in human pluripotent stem cell‐derived organoids. Integrated with transcriptomic and spatial data, it reveals NOTCH‐mediated stromal‐progenitor crosstalk orchestrates clonal dynamics and spatial zonation during early hematopoietic development, offering a non ...
