Eosinophils‐Induced Lumican Secretion by Synovial Fibroblasts Alleviates Cartilage Degradation via the TGF‐β Pathway Mediated by Anxa1 Binding

Advanced Science, EarlyView.
Eosinophils play a crucial role in the progression of temporomandibular joint osteoarthritis (TMJOA). This study demonstrates that eosinophils, induced by OVA/IL‐5, promote Lumican secretion in the synovium, which binds to Annexin A1 in chondrocytes, inhibiting transforming growth factor β2 and Smad2/3 phosphorylation.

Intracellular and Extracellular ATP Coordinately Regulate the Inverse Correlation between Osteoclast Survival and Bone Resorption*

Journal of Biological Chemistry, 2012
Background: Mature osteoclasts with a spontaneous tendency toward apoptosis resorb bone efficiently during their short lifespan. Results: Released ATP from intracellular stores has a negative impact on the bone resorption activity of osteoclasts by ...

Identification of NIBAN2‐Regulated RUNX2 Alternative Splicing Presents Novel Strategies for Antagonizing Osteoporosis

Advanced Science, EarlyView.
NIBAN2 interacts with the HNRNPU‐cored spliceosome complex and alters its components to regulate the alternative splicing of RUNX2, which ultimately cause an increase in functional RUNX2 (nuclear localization sequence complete) but a decrease in dysfunctional Runx2 (exon 6‐exclusive) isoforms to reinforce osteoblast differentiation.

Inhibitory Effects of 2N1HIA (2-(3-(2-Fluoro-4-Methoxyphenyl)-6-Oxo-1(6H)-Pyridazinyl)-N-1H-Indol-5-Ylacetamide) on Osteoclast Differentiation via Suppressing Cathepsin K Expression

Molecules, 2018
Osteoclasts are large multinucleated cells which are induced by the regulation of the receptor activator of nuclear factor kappa-Β ligand (RANKL), which is important in bone resorption.

Inhibition of Ferroptosis Delays Aging and Extends Healthspan Across Multiple Species

Advanced 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.

Mechanobiological regulation of bone remodeling -- Theoretical development of a coupled systems biology-micromechanical approach [PDF]

arXiv, 2012
Bone remodeling involves the coordinated removal of bone by osteoclasts and addition of bone by osteoblasts, a process that is modulated by the prevailing mechanical environment. In this paper a fully coupled model of bone remodeling is developed, based on coupling a bone cell population model with a micromechanical homogenization scheme of bone ...

Manipulation of Oxygen Tension in Damaged Regions via Hypoxia‐Induced IPN Hydrogel Microspheres for Intervertebral Disc Regeneration

Advanced Science, EarlyView.
A novel interpenetrating network hydrogel microsphere (NSC‐Exos@HIMS) is developed to manipulate oxygen tension in damaged regions and recruit endogenous stem cells. In vitro and in vivo results show that NSC‐Exos@HIMS maintains the hypoxia microenvironment for up to 5 days, which triggers nucleus pulposus cell‐like differentiation and enhanced ECM ...
