PSMD14 Stabilizes SLC7A11 to Ameliorate Glucocorticoid‐Induced Osteoporosis by Suppressing Osteocyte Ferroptosis

Advanced Science, EarlyView.
Glucocorticoid‐induced osteoporosis (GIOP) triggers osteocyte ferroptosis via SLC7A11 degradation. PSMD14 stabilizes SLC7A11 by counteracting glucocorticoid‐driven ubiquitination, preserving cystine uptake and glutathione synthesis. AAV‐mediated PSMD14 delivery or its agonist Pantethine rescues osteocyte survival and bone loss in GIOP mice.

Testosterone Delays Bone Microstructural Destruction via Osteoblast‐Androgen Receptor‐Mediated Upregulation of Tenascin‐C

Advanced Science, EarlyView.
This study reveals that Testosterone–Androgen Receptor signaling delays elderly male bone destruction by upregulation of the osteoblastic extracellular tenascin‐C (TNC). The osteoprotective effect of fibrinogen C‐terminus of TNC is demonstrated in male osteoporotic mice model that osteoblast‐specific Ar‐knockout, potentially via inhibition of ...

Three-dimensional anatomy of the ostrich (Struthio camelus) knee joint [PDF]

, 2014
The three-dimensional anatomy of the ostrich (Struthio camelus) knee (femorotibial, femorofibular, and femoropatellar) joint has scarcely been studied, and could elucidate certain mechanobiological properties of sesamoid bones.

Pinosylvin Inhibits Inflammatory and Osteoclastogenesis via NLRP3 Inflammasome

Advanced Science, EarlyView.
Pinosylvin blocks LPS and RANKL induced NEK7/NLRP3 interaction, inhibiting NLRP3 inflammasome oligomerization and assembly, reducing IL‐1β maturation and GSDMD cleavage, and improving the inflammatory microenvironment and abnormal osteoclastogenesis. Abstract Pro‐inflammatory cytokines such as TNF, IL‐1, and IL‐6 trigger aberrant osteoclastogenesis and
