TP53 Loss Elevates NF‐κB‐IFN‐β‐MHC‐Ia Signaling to Promote NK Cell Resistance in Osteosarcoma

Advanced Science, EarlyView.
TP53 loss in a transforming or osteosarcoma cell promotes cytosolic DNA accumulation, activating NF‐κB‐dependent IFN‐β production. Autocrine IFN‐β signaling increases cell‐surface HLA‐Ia expression, strengthens inhibitory KIR signaling in natural killer cells, and thereby enables the affected cell to evade NK cell‐mediated cytotoxicity.

CXCR4 is a response gene for parathyroid hormone which affects osteoblast and osteoclast function in vitro

Bone & Joint Research
Aims: To investigate the role of CXCR4 in response to teriparatide (TPTD) treatment in osteoblasts and osteoclasts. Methods: Primary murine and human osteoblasts and osteoclasts, MC3T3 cell lines, and hMSC-TERT4 cell lines were treated with TPTD and/or

Hierarchical Nanoplatform Integrating Oxidative–Acidic Microenvironment Remodeling and Bone Homeostasis Modulation for Diabetic Bone Defect Therapy

Advanced Science, EarlyView.
A hierarchical CM/LDH nanoplatform integrates ROS‐scavenging Ce‐MOF nanozymes with acid‐neutralizing CaAl‐LDH and is delivered within GelMA hydrogel to diabetic bone defects. By remodeling the oxidative‐acidic microenvironment, preserving mitochondrial homeostasis, and suppressing mtDNA–cGAS–STING inflammatory signaling, CM/LDH reduces proinflammatory ...

Puerarin‑Loaded pH‑Responsive ZIF‑90 Nanoparticles Ameliorate Osteoporosis via Enhancing H3K18 Lactylation and Suppressing Aberrant Osteoclast Activation

Advanced Science, EarlyView.
Schematic illustration of the mechanism by which ZIF‐90@PU alleviates osteoporosis via H3K18la‐mediated NFATc1 pathway suppression. ABSTRACT Osteoporosis is characterized by dysregulated osteoclast activity, leading to excessive bone resorption and structural damage.

Persistent Zn2+ Influx‐Mediated Deacetylation of ANXA2 Regulates the “Zn2+‐Autophagic Flux” and Alleviates Intervertebral Disc Degeneration

Advanced Science, EarlyView.
Zinc transporter SLC39A14 sustains intracellular Zn2+ levels to activate SIRT3‑dependent ANXA2 deacetylation at K302. This modification weakens ANXA2‑mTOR binding and releases autophagic‑flux suppression in nucleus pulposus cells. Dysregulated Zn2+ homeostasis disrupts this axis to drive intervertebral disc degeneration.

STING/Type I Interferon Pathway Activation Confers Multimodal Therapeutic Benefits in Osteomyelitis

Advanced Science, EarlyView.
STING/type I interferon signaling counteracts osteomyelitis through coordinated control of pain, bone destruction, and abscess formation. It inhibits pathogen‐induced nociceptor activation, restrains osteoclast‐mediated bone resorption, and suppresses IL‐1β‐driven neutrophil recruitment.

Viridicatol from the Deep‐Sea‐Derived Fungus Alleviates Bone Loss by Targeting the Wnt/SHN3 Pathway

Advanced Science
As an enticing bone anabolic target, short‐term inhibition of Schnurri‐3 (SHN3) resulted in high‐bone mass due to augmented osteoblast activity. However, no studies are conducted to identify natural products targeting SHN3 inhibition. Herein, a screening

Influence of the Sodium Titanate Crystal Size of Biomimetic Dental Implants on Osteoblastic Behavior: An In Vitro Study

Biomimetics
Treating the surfaces of dental implants in an alkaline medium allows us to obtain microstructures of sodium titanate crystals that favor the appearance of apatite in the physiological environment, producing osteoconductive surfaces.
