Molecular Mechanism of Runx2-Dependent Bone Development.

Molecules and cells, 2020
Runx2 is an essential transcription factor for skeletal development. It is expressed in multipotent mesenchymal cells, osteoblast-lineage cells, and chondrocytes. Runx2 plays a major role in chondrocyte maturation, and Runx3 is partly involved. Runx2 regulates chondrocyte proliferation by directly regulating Ihh expression.

Hyperlipidemia Aggravates Alveolar Bone Loss via Periodontal Ligament Stem Cell Ferroptosis Through GSK3β Dependent Ubiquitin‐Mediated NRF2 Degradation

Advanced Science, EarlyView.
Lipid metabolic stress triggers ferroptosis in PDLSCs through the GSK3β/NRF2 pathway, thereby aggravating periodontal bone loss. Upregulated GSK3β promotes NRF2 ubiquitination and proteasomal degradation via β‐TrCP, suppressing NRF2 nuclear translocation and antioxidant target expression.

Sono‐Mechanogenetics: Linking Ultrasound Physics With Cellular Mechanobiology

Advanced Science, EarlyView.
Sono‐mechanogenetics links ultrasound physics with cellular mechanotransduction to enable noninvasive control of engineered biological systems. Acoustic forces generate distinct deformation modes that activate intracellular signaling pathways, which can be coupled to synthetic gene circuits to regulate diverse cellular functions, including gene ...

Bamboo‐Like Whiskers‐Reinforced Bioceramics Accelerate Large Segmental Bone Regeneration via Dual Modulation of Type‐H Vessels and Osteoinduction

Advanced Science, EarlyView.
The graphical abstract image of bamboo‐like whisker‐reinforced Ca‐P bioceramics accelerating large segmental bone regeneration. ABSTRACT Regenerative repair of segmental bone defect remains a major clinical challenge. The conventional mental implants suffer from mechanical strength mismatch and long‐term foreign bodies presence.

Boosting Sensory Nerve‐to‐Bone Interactions Enhances Hedgehog Mediated Calvarial Bone Repair

Advanced Science, EarlyView.
Boosting sensory nerve activity via TrkA agonism strongly accelerates calvarial bone repair in adult mice. Furthermore, single‐cell RNA sequencing and neuron–bone interactome analyses identify these sensory neurons as a direct neural source of Hedgehog pathway ligands. Consequently, these ligands drive osteoblast differentiation of skeletal progenitors,

RUNX2 isoform II protects cancer cells from ferroptosis and apoptosis by promoting PRDX2 expression in oral squamous cell carcinoma

eLife
Ferroptosis is a distinct iron-dependent programmed cell death and plays important roles in tumor suppression. However, the regulatory mechanisms of ferroptosis need further exploration. RUNT-related transcription factor 2 (RUNX2), a transcription factor,

Light‐Switched Mesenchymal Stem Cells for In Situ Exosome Amplification in Craniofacial Bone Defect Reconstruction

Advanced Science, EarlyView.
Light‐switchable MSCs (MSC‐UCNPs) were constructed by intracellular incorporation of UCNPs. Upon 980 nm irradiation, UCNPs emitted localized ultraviolet light (365 nm), activating the ROS/HEXB/LAMP1 signaling pathway to suppress lysosome–multivesicular body fusion and thereby enhance exosome biogenesis. Embedded within an injectable hydrogel, MSC‐UCNPs
