[Molecular biological research progress of non-coding RNAs modulating osteoarthritis]

Area of Science:

• Molecular Biology
• Genetics
• Biochemistry

Background:

• Osteoarthritis (OA) is a degenerative joint disease with complex molecular underpinnings.
• Non-coding RNAs (ncRNAs) are increasingly recognized as key regulators in various biological processes, including disease pathogenesis.

Purpose of the Study:

• To review the current molecular biological research on ncRNAs involved in osteoarthritis (OA).
• To provide a foundation for further biological investigation and clinical applications in OA treatment.

Main Methods:

• Comprehensive literature review of domestic and international studies on ncRNAs in OA.
• Identification of ncRNAs using high-throughput sequencing and microarray technologies.
• Validation of ncRNA involvement in OA regulation via RT-PCR and functional studies (knock-down/overexpression).

Main Results:

• Non-coding RNAs, classified by length, are implicated in OA pathology.
• Complex gene expression networks involving ncRNAs and coding RNAs are observed in OA.
• Functional studies elucidate the mechanisms by which prominent ncRNAs mediate OA targets.

Conclusions:

• The molecular mechanisms of ncRNAs in OA are under preliminary investigation.
• Key structural and functional aspects of ncRNAs in OA mediation require further elucidation.
• Understanding ncRNA interactions is crucial for identifying definitive therapeutic targets for OA.
