Ribosome biogenesis in osteoarthritis: mechanisms and therapeutic potential

Area of Science:

• Molecular Biology
• Cell Biology
• Rheumatology

Background:

• Ribosome biogenesis is crucial for cellular protein synthesis; defects are linked to various diseases.
• Osteoarthritis (OA) pathogenesis is complex, with growing evidence implicating ribosome biogenesis dysregulation.
• Impaired ribosome biogenesis in chondrocytes may drive OA initiation and progression by affecting metabolism and stress responses, suggesting OA as an acquired ribosomopathy.

Purpose of the Study:

• To systematically review factors in ribosome biogenesis impacting chondrocyte function and joint homeostasis.
• To evaluate the therapeutic potential of targeting ribosome biogenesis for OA treatment.
• To integrate findings from in vivo and in vitro models.

Main Methods:

• Literature review focusing on non-coding RNAs, ribosomal proteins, and translation regulators.
• Analysis of in vivo and in vitro studies on ribosome biogenesis in OA.
• Synthesis of current research on chondrocyte function and joint tissue homeostasis.

Main Results:

• Ribosome biogenesis factors significantly influence chondrocyte function and joint tissue homeostasis.
• Dysregulated ribosome biogenesis is implicated in OA pathogenesis.
• Key molecules like non-coding RNAs, ribosomal proteins, and translation regulators are central to this process.

Conclusions:

• Investigating ribosome biogenesis in OA provides new insights into pathological mechanisms.
• This research offers a foundation for developing novel OA therapeutic strategies.
• Targeting ribosome biogenesis may offer disease-modifying treatment options for osteoarthritis.
