Raftlin and 8-iso-prostaglandin F2α levels and gene network analysis in patients with Modic changes

Area of Science:

• Biomarkers
• Oxidative Stress
• Inflammation
• Spine Degeneration

Background:

• Oxidative stress is implicated in various diseases.
• Modic changes (MCs) are vertebral endplate abnormalities associated with low back pain.
• 8-iso-prostaglandin F2α (8-iso-PGF2α) is a proposed indicator of oxidative stress.
• Raftlin is an inflammatory biomarker found in inflammatory diseases.

Purpose of the Study:

• To assess Raftlin and 8-iso-PGF2α levels in patients with Modic changes (MCs).
• To investigate the relationship between oxidative stress, inflammation, and MCs.

Main Methods:

• Enzyme-linked immunosorbent assay (ELISA) was used to measure serum levels of 8-iso-PGF2α and Raftlin.
• 45 patients with MCs (types I, II, and III) and 45 age- and sex-matched controls were included.

Main Results:

• Raftlin levels correlated positively with prostaglandin levels (p < 0.05).
• Both 8-iso-PGF2α and Raftlin levels were elevated in patients with MCs compared to controls (p < 0.05).
• Significant positive correlations were observed between MC types (I, II, III) and Raftlin, as well as between MC types and 8-iso-PGF2α (p < 0.001).

Conclusions:

• Oxidative stress may be aggravated in MC-I, potentially leading to inflammation.
• Elevated 8-iso-PGF2α and Raftlin in MC-II and MC-III might represent an adaptive response to oxidative stress.
• Raftlin and 8-iso-PGF2α show potential as biomarkers for oxidative stress and inflammation in Modic changes.
