Mechanosensitive Piezo1/Osteocalcin/Irisin Axis Protects Against Disuse‐Induced Muscle Atrophy

Advanced Science, EarlyView.
Mechanical unloading suppresses bone Piezo1 expression, which reduces circulating undercarboxylated osteocalcin (unOCN). unOCN reduction subsequently exacerbates IMM‐induced Fndc5/Irisin decrease and drives severe muscle atrophy. Bone Piezo1 activation or exogenous osteocalcin/Irisin ameliorate muscle atrophy, while muscle‐specific Gprc6a or Fndc5 ...

Drug‐Induced Cuproptosis Defines the Therapeutic Window of Celecoxib in Intervertebral Disc Degeneration via the HSP90‐RBX1 Axis

Advanced Science, EarlyView.
This study reveals the dual role of celecoxib in intervertebral disc degeneration. While low concentrations are protective, high concentrations induce toxicity by upregulating HSP90, which synergizes with USP15 to deubiquitinate and stabilize RBX1. This leads to degradation of COMMD1/ATP7B, copper dyshomeostasis, and ultimately, cuproptosis.
