[Research progress on long non-coding RNA (lncRNA) in osteoarthritis]

Area of Science:

• Biochemistry
• Genetics
• Molecular Biology

Background:

• Osteoarthritis (OA) is a prevalent degenerative joint disease significantly impacting patient quality of life, with cartilage degeneration being a primary pathological feature.
• The incidence of OA escalates with age, highlighting the need for effective diagnostic and therapeutic strategies.
• Long non-coding RNAs (lncRNAs) have emerged as critical regulators in various biological processes, including those implicated in OA pathogenesis.

Purpose of the Study:

• To summarize recent findings (2014-2019) on the differential expression of lncRNAs in OA.
• To elucidate the mechanisms by which lncRNAs regulate chondrocyte function and cartilage matrix metabolism.
• To explore the potential of lncRNAs as biomarkers and therapeutic targets for OA.

Main Methods:

• Literature review of research published between 2014 and 2019 focusing on lncRNA expression and function in OA.
• Analysis of studies investigating the role of specific lncRNAs in chondrocyte behavior and cartilage homeostasis.
• Synthesis of information regarding the regulatory pathways involving lncRNAs in OA pathogenesis.

Main Results:

• Numerous lncRNAs exhibit differential expression patterns specific to OA.
• lncRNAs play crucial roles in regulating chondrocyte proliferation, apoptosis, and differentiation.
• lncRNAs are involved in modulating the metabolism of cartilage matrix components, influencing cartilage degradation.

Conclusions:

• Altered lncRNA expression during OA development suggests their involvement in disease progression.
• lncRNAs hold significant promise as potential biomarkers for early diagnosis and prognosis of OA.
• lncRNAs represent promising therapeutic targets for the development of novel OA treatments.
