Abstract:
Objective To study the relationship of the plasma levels of miRNA-491-5p in Han population in Shaanxi Province and the changes of single nucleotide polymorphisms (SNP ) of the target gene matrix metalloproteinases-9 (MMP-9 ) of miRNA-4 9 1-5 p (has-miR-4 9 1-5 p ) with the incidence risk and prognosis of premature coronary artery disease (pCAD)through the case-control design.Methods In this study,we made a consecutive recruitment of 270 pCAD cases in the case group and 300 cases in the control group.Using the polymorphism method of polymerase chain reaction and restriction fragment length (PCR-RFLP),target gene MMP-9 of has-miR-491-5p and rs1056628 genotypes was detected to compare the association between the variant genotypes and pCAD.Results In the changes of rs1056628C-A polymorphisms,compared with that of CC genotypes (the incidence was 42%),the risks of having coronary heart disease in the individuals carrying CA and AA genotypes were 31%,the difference was statistically significant (P=0.045).The risks of developing coronary heart disease in the individuals carrying CA and AA genotypes were reduced more significantly in the population with low total cholesterol (TC),and low low-density lipoprotein cholesterol (LDL-C).Conclusion Target gene MMP-9 of has-miRNA-491-5p rs1056628C-A polymorphism is associated with the reduced incidence risk of pCAD,and carrying C alleles is an independent risk factor for pCAD.
