Clinical significance and regulatory mechanism of miR-4284 in lumbar intervertebral disc degeneration

Key Points

The aim is to evaluate the role of miR-4284 as a biomarker in lumbar intervertebral disc degeneration (LDD) and its underlying mechanisms.
Analyzed miR-4284 levels in lumbar intervertebral disc tissues.
Examined its effects on inflammation and mitochondrial function in nucleus pulposus (NP) cells.
Investigated the relationship between miR-4284 and CYCS.
miR-4284 levels were significantly lower in cases of LDD.
Targeting CYCS by miR-4284 reduced inflammation and oxidative stress in NP cells.
miR-4284 inhibited apoptosis and improved mitochondrial function, which may slow LDD progression.

Abstract

miR-4284 is significantly decreased in LDD and may serve as a protective biomarker. By targeting CYCS, it alleviates inflammation and oxidative stress, inhibits apoptosis, and mitigates mitochondrial dysfunction in NP cells, thereby potentially delaying LDD progression.
