Pilose antler polypeptides promote chondrocyte proliferation via the tyrosine kinase signaling pathway

open access: yesJournal of Occupational Medicine and Toxicology, 2011
Background Pilose antler polypeptides (PAP) have been reported to promote chondrocyte proliferation. However, the underlying mechanism remains unclear. The present study was to investigate the effects of PAP on the proliferation of chondrocytes and its ...

Targeting the PGRN‐BMP Lysosomal Axis With NPs@PGRN Reverses Immunometabolic Dysfunction in Chronic Septic Arthritis

open access: yesAdvanced Science, EarlyView.
Chronic septic arthritis involves intracellular bacterial persistence and lipid‐immune crosstalk via the PGRN‐BMP lysosomal axis. A dual‐targeting nanoparticle system (NPs@PGRN) restores lysosomal bactericidal function, reduces bacterial burden, and reprograms macrophage immunity, offering a novel therapeutic strategy. ABSTRACT Chronic septic arthritis,

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

open access: yesScientific 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 ...

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

open access: yesPoultry 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

Time‐Controlled Refrigerated Stem Cell Therapy Mitigates Scleroderma Fibrosis via Modulation of Mitochondrial Autophagy and Gut Metabolism

open access: yesAdvanced Science, EarlyView.
This study established an RT‐MSCs‐based therapeutic approach for scleroderma in mice. RT‐MSCs attenuated fibrosis by regulating mitochondrial autophagy and restored gut microbiota homeostasis. Metabolomic analyses confirmed recovery of key metabolites, and RT‐MSCs demonstrated favorable lesion targeting and safety profiles.

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 ...

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

open access: yesFEBS 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
