Mastication‐Induced Electrical Stimulation Activates Prg4+ Chondroprogenitors for Osteoarthritis Therapy

Advanced Science, EarlyView.
This study presents a ″trash‐to‐treasure″ strategy that converts harmful joint overloads into beneficial electrical cues. The biodegradable MagPie, by providing piezoelectrical stimulation and releasing Mg2+ during mastication, exerts synergistic pro‐regenerative and anti‐inflammatory effects on Prg4+ cells via the ECM‐mediated FAK‐PI3K‐Akt axis ...

Isorhamnetin inhibits mechanical stress-induced chondrocyte apoptosis through activation of the ROS/SRC/FOXO1 signaling pathway

Scientific Reports
Intervertebral disc degeneration (IDD), a chronic degenerative disease, is characterized by pain without a satisfactory therapeutic strategy. Excessive mechanical pressure contributes to the pathological development of IDD by inducing chondrocyte ...

Lesion Site‐Targeted Microspheres Modulate Nav1.7‐Related Signaling for Osteoarthritis Treatment

Advanced Science, EarlyView.
Cartilage‐targeted carbamazepine‐loaded WYRGRL‐modified composite microspheres (CBZ/WCOM) anchor to exposed type II collagen in osteoarthritic lesions and release carbamazepine under acidic conditions. This bind‐then‐release platform modulates Nav1.7‐related sodium signaling, Na⁺/Ca²⁺ exchanger‐associated Ca2+ dynamics, and heat shock protein 70 ...

miR-1737 targets TAK1 to mediate the BMP-Smad signaling pathway to regulate the molecular mechanism of chicken tibial chondrodysplasia

Poultry Science
Tibial dyschondroplasia (TD) is a prevalent skeletal disorder in the modern broiler poultry industry. MicroRNAs (miRNAs) regulate various biological processes. Our previous studies suggest miR-1737 plays a role in cartilage development, but its mechanism

Ultrasound‐Activatable Piezoelectric Hydrogel Reprograms Mitochondrial Epigenetics for Osteoarthritis Therapy via the mTOR/GATD3A Axis

Advanced Science, EarlyView.
An ultrasound‐activatable piezoelectric hydrogel reprograms chondrocyte mitochondrial epigenetics via the mTOR/GATD3A axis, clearing damaged mitochondria and alleviating osteoarthritis progression in both mouse models and human cartilage explants. ABSTRACT The avascular nature of cartilage hinders drug delivery for osteoarthritis (OA) therapy.

Perichondrial expression of Wdr5 regulates chondrocyte proliferation and differentiation

Developmental Biology, 2009
Wdr5 is developmentally expressed in osteoblasts and is required for osteoblast differentiation. Mice overexpressing Wdr5 under the control of the mouse alpha(1)I collagen promoter (Col I-Wdr5) display accelerated osteoblast differentiation as well as accelerated chondrocyte differentiation, suggesting that overexpression of Wdr5 in osteoblasts affects

miR‐373 regulates inflammatory cytokine‐mediated chondrocyte proliferation in osteoarthritis by targeting the P2X7 receptor

FEBS Open Bio, 2018
Inflammatory cytokines commonly initiate extreme changes in the synovium and cartilage microenvironment of osteoarthritis (OA) patients, which subsequently cause cellular dysfunction, especially in chondrocytes. It has been reported that induction of the

Anti‐inflammatory and osteogenic effects of transcutaneous electrical nerve stimulation in knee osteoarthritis rats via the regulation of the intestinal microbiota

Animal Models and Experimental Medicine, EarlyView.
Transcutaneous electrical nerve stimulation (TENS) improved knee osteoarthritis (KOA) in rats by regulating interleukin‐1β (IL‐1β), IL‐6, and IL‐8 expressions and the bone morphogenetic protein 2 (BMP‐2)/transforming growth factor β (TGF‐β) signaling pathway.
