The effects of extracellular matrix-degrading enzymes polymorphisms on intervertebral disc degeneration

Abstract

Objective

The objective of the current study was to investigate the correlation between polymorphisms in extracellular matrix-degrading enzymes and the risk of intervertebral disc degeneration (IDD) diseases.

Methods

The databases PubMed, Embase, and Cochrane Database were systematically queried from the inception until March 2023 to ascertain studies that meet the eligibility criteria. Utilizing a standardized data collection form to extract data from individual studies. The data were quantified using odds ratio (OR) along with its corresponding 95% confidence interval (95% CI), following an allelic model of inheritance.

Results

The study included a total of nine studies and indicated that the presence of rs17576 in the MMP9 gene was significantly associated with an increased risk of IDD diseases (GG: 1.30, 95% CI [1.09–1.55], p = 0.004). The presence of other polymorphisms in extracellular matrix-degrading enzymes did not exhibit a significant association with the susceptibility to IDD.

Conclusion

The current study demonstrated a noteworthy correlation between the GG genotype of MMP-9 rs17576 and susceptibility to IDD. The available evidence is insufficient to substantiate the correlation between other extracellular matrix-degrading enzymes and susceptibility to IDD. The constraints of this analysis necessitate further research involving larger sample sizes across diverse ethnicities to provide a comprehensive understanding of the true impact of these polymorphisms on susceptibility to IDD.
