The Regulatory Variant -108C/T in the Promoter of Paraoxonase 1 (PON1) Gene has a More Important Role in Regulating PON1 Activity Compared to rs3735590 in 3'-UTR in Patients with Coronary Artery Disease.

Background

This study aimed to assess the serum activity of paraoxonase 1 (PON1) in patients with coronary artery disease (CAD) based on two genetic variants including the -108C/T variant in the promoter region and the rs3735590 variant in the binding site of miR-616 at the 3'-UTR of the PON1 gene.

Materials and Methods

A total of 140 subjects who exhibited clinical symptoms of CAD underwent diagnostic coronary angiography. The patients with CAD were further categorized into two groups: single-vessel disease (SVD) and multi-vessel disease (MVD). The study variants were genotyped using the restriction fragment length polymorphism (RFLP) technique after polymerase chain reaction amplification.

Results

After adjusting for age, gender, body mass index, metformin, and statin usage, a significant association was observed between the -108C/T variant and PON1 activity (

Conclusions

Our study findings indicate a significant decrease in PON1 activity among patients with obstructive CAD. Notably, our results suggest that the -108C/T variant exerts a greater influence on PON1 activity compared to the rs3735590 variant. These findings highlight the crucial role of the -108C/T variant in modulating PON1 activity within the context of atherosclerosis.
