Genetic variants and expression study of FOXP3 gene in acute coronary syndrome in Iranian patients

AbstractAcute coronary syndrome (ACS) is the most serious form of coronary artery disease. Inflammatory processes participate in different stages of this disorder. FOXP3 gene plays an important role for the development and function of regulatory T cells. Consequently, the expression level and polymorphisms of this gene have been studied in many immune related diseases. In the present study, we analysed the expression of FOXP3 as well as the association between two variants in this gene (rs3761548A/C and rs5902434del/ATT) and occurrence of ACS in Iranian patients. FOXP3 expression analysis showed a significant decrease in patients with ACS compared with controls (P = 0.029). In addition, a significant decrease has been detected in female patients compared with normal female subjects (P = 0.020). No significant change has been observed in FOXP3 expression in male patients compared with normal male subjects. In addition, no difference has been detected between ACS and normal subjects in combined genotype frequencies of both polymorphisms and the allele frequencies of rs5902434. However, rs3761548 C allele was more prevalent in controls compared with patients with ACS (P = 0.024). Consequently, our data demonstrated that FOXP3 expression is markedly decreased in female patients with ACS, which highlight the role of immune responses in plaque destabilization in such patients.
