Circular RNAs in nucleus pulposus cell function and intervertebral disc degeneration

Area of Science:

• Biochemistry
• Molecular Biology
• Regenerative Medicine

Background:

• Intervertebral disc degeneration (IDD) is a primary cause of low back pain and global disability.
• While aging is a factor, genetic and environmental influences, particularly nucleus pulposus cell dysfunction, drive IDD.
• Circular RNAs (circRNAs), a class of non-coding RNAs, are emerging as key regulators in cellular processes.

Purpose of the Study:

• To review the current understanding of circRNA deregulation in IDD.
• To explore the impact of circRNAs on nucleus pulposus cell functions like proliferation, apoptosis, and extracellular matrix (ECM) balance.
• To discuss the therapeutic potential of circRNAs for managing IDD.

Main Methods:

• Literature review of studies investigating circRNAs in intervertebral disc degeneration.
• Analysis of research on circRNA functions in nucleus pulposus cells.
• Synthesis of findings on circRNA-mediated regulation of cellular processes relevant to IDD.

Main Results:

• CircRNAs are deregulated in nucleus pulposus cells during IDD.
• Aberrant circRNA expression influences nucleus pulposus cell proliferation, apoptosis, and ECM synthesis/degradation.
• Specific circRNAs have been identified as key players in IDD pathogenesis.

Conclusions:

• CircRNA deregulation is a significant factor in the pathogenesis of IDD.
• Targeting circRNAs in nucleus pulposus cells presents a promising therapeutic strategy for IDD.
• Further research into circRNA mechanisms could lead to novel treatments for low back pain associated with IDD.
