Abstract
- Background We aimed to examine the role of the rs6060566 polymorphism of the reactive oxygen species modulator-1 (ROMO-1) gene in the development of myocardial infarction (MI) in Caucasians with type 2 diabetes mellitus (T2DM). Methods A total of 1072 subjects with T2DM were enrolled in cross-sectional case-control study: 335 subjects with MI and 737 subjects without clinical signs of coronary artery disease (CAD). Genetic analysis of the rs6060566 polymorphism was performed in all subjects. To assess the degree of coronary artery obstruction, a subpopulation of 128 subjects with T2DM underwent coronary computed tomography (CT) angiography. Next, endarterectomy samples were obtained during myocardial revascularization from diffusely diseased coronary arteries in 40 cases, which were analysed for ROMO-1 expression according to their genotype. Results There were no statistically significant associations between different genotypes or alleles of the rs6060566 polymorphism and MI in subjects with T2DM. The carriers of the C allele of the ROMO-1 rs6060566 had a threefold increased likelihood of having coronary artery stenosis (AOR = 3.27, 95% CI 1.16–9.20). Furthermore, the carriers of the C allele showed higher number of positive cells for ROMO-1 expression in endarterectomy samples of coronary arteries. Conclusions In accordance to our study, the rs6060566 polymorphism of the ROMO-1 gene is not the risk factor for MI in Caucasians with T2DM. However, we found that subjects carrying the C allele were at a 3.27-fold increased risk of developing severe CAD compared with those who had nonobstructive CAD. Moreover, The C allele carriers showed statistically higher number of cells positive for ROMO-1 compared with T allele carriers in coronary endarterectomy samples.
