Plasma CXCL1 levels and TRAF3IP2 variants in patients with myocardial infarction.

ABSTRACT: BACKGROUND:IL-17A plays an important role in inflammatory responses in myocardial infarction (MI). IL-17A signals through its receptor, for which, Act1 (TRAF3IP2) functions as a key upstream adaptor in the pathway. AIM:To compare frequencies of functional polymorphisms of TRAF3IP2 (rs13210247, rs33980500) between patients with MI and healthy controls. METHODS:The selected SNPs were studied in 201 Iranian MI patients and 201 healthy blood donors from Fars Province by PCR-RFLP in association with clinicopathologic criteria of patients. CXCL1 plasma levels in 126 MI patients and 50 normal subjects were measured by ELISA. RESULTS:A significant increase in the mutant (T) allele of TRAF3IP2 rs33980500 in patients with diastolic dysfunction of the heart (P = .01) was observed. The highest correlation, however, was observed between the TRAF3IP2 rs33980500 TT genotype and T allele with left main coronary artery stenosis (P = .01, P < .001; OR = 31.03). T allele of TRAF3IP2 rs33980500 was also associated with female gender, family history of cardiovascular disease, and mechanical complications of heart (P = .04, P = .02, and P = .01, respectively). Moreover, TRAF3IP2 rs13210247 (G) correlated with mechanical complications of the heart (P = .01). A significant increase in the plasma levels of CXCL1 chemokine in patients (P = .0006) associated with TT genotype of TRAF3IP2 (rs33980500) was observed (P = .04). CONCLUSION:The gene variants of Act1 adaptor are associated with correlates of poor outcome in patients with MI and plasma CXCL1 levels.
