Abstract:
Objective To investigate the association of serum levels of matrix metalloproteinase-12 (MMP-12) and a functional polymorphism in the promoter - 82A/G of the MMP-12 gene with acute atherosclerotic cerebral infarction (ACI).Methods All 608 cascs of acute ACI and 374 healthy controls were included in the study.Serum levels of MMP-12 were measured using the enzyme-linked immunosorbent assay (ELISA). At the same time,polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was performed on the - 82A/G polymorphism in the MMP-12 gene.Results The serum levels of MMP-12 in ACI group (( 17.36 ± 9.12) ng/ml) were not significantly higher than those in the healthy control group ( ( 17.42 ± 7.70) ng/ml,t ＝ 0.047,P =0.962).The frequency of the AG + GG genotypes was not significantly different between the two groups (7.6％ vs 5.9％,x2 =0.281,P =0.584),and the frequencies of the G allele were 3.8％ and 2.9％ in the ACI group and the control group respectively which were also not significantly different between the two groups ( x2 =0.746,P =0.374).Conclusion There is no correlation between serum level with genetic polymorphism in MMP-12 promoter (-82A/G) and cerebral infarction.
