Abstract

Insights

The mechanosensitive ion channel Piezo1 plays a key role in osteoarthritis (OA) pathogenesis by sensing mechanical stress. Targeting Piezo1 offers a promising therapeutic strategy for OA treatment.

Area of Science:

  • Biomedical Engineering
  • Molecular Biology
  • Rheumatology

Background:

  • Osteoarthritis (OA) is a degenerative joint disease characterized by cartilage breakdown and pain.
  • Mechanical stress is a known contributor to OA pathogenesis.
  • The role of mechanosensitive ion channels in OA is an emerging area of research.

Purpose of the Study:

  • To review the role of the mechanosensitive ion channel Piezo1 in osteoarthritis (OA) pathogenesis.
  • To summarize recent advances in Piezo1 as a potential therapeutic target for OA.

Main Methods:

  • A comprehensive review of recent domestic and international research literature on Piezo1.
  • Analysis of studies investigating Piezo1's involvement in chondrocyte injury, inflammation, extracellular matrix degradation, and osteophyte formation.
  • Examination of Piezo1-targeted inhibitors, activators, and modulators.

Main Results:

  • Piezo1 mediates calcium (Ca2+) influx in response to abnormal mechanical stress, activating PI3K/AKT/mTOR and MAPK/ERK signaling pathways.
  • Activation of these pathways promotes chondrocyte apoptosis, impairs autophagy, and leads to matrix degradation.
  • Preclinical studies indicate potential chondroprotective effects of GsMTx4, Piezo1-siRNA, Dooku1, and artemisinin, though further verification is needed.

Conclusions:

  • Piezo1 is a critical mediator linking mechanical stress to OA progression.
  • Piezo1 represents a promising therapeutic target for OA.
  • Future research should focus on mechanism elucidation, developing specific modulators, and conducting rigorous clinical studies.
