ABSTRACT
ObjectiveThis study is designed to investigate the relationship between STR polymorphism in HO-1 gene promoter and susceptibility of CAD,in order to provide a new strategy for prevention and treatment of CAD by using HO-1.Methods200 patients who were diagnosed as CAD by coronary angiography were selected in this study.100 subjects without evidence of CAD under coronary angiography with their sex and age similar to CAD patients were selected as controls.Genotyping was performed using polymerase chain reaction followed by capillary electrophoresis automated DNA sequencer.Each size of the (GT) n repeat was calculated using the GeneMapper Analysis software.ResultsA (GT)n polymorphism was found in the HO-1 gene promoter with n =16 ~39.Subjects with n≤29 expressed much more HO-1 protein than those with n >29( P <0.01 ).The alleles were then classified into two subgroups,S'allele (n 29 ) and L'allele (n >29),the subjects were then classified as having an S/S,S/L,or L/L genotype.Subjects with the L allele ( L/L + L/S genotypes) had more chance to get CAD than those with S/S genotype ( adjusted OR =1.83,95 % CI =1.04 - 3.24).Stratified analysis further showed that L allele ( L/L + L/S genotypes) was susceptive to CAD in patients who smoke (adjusted OR =2.59,95% CI =1.16 -5.80).ConclusionsThe (GT)n polymorphism in HO-1 gene promoter is related to susceptibility to CAD,especially in those patients who smoke.
