Association of paraoxonase-1 (Q192R) gene polymorphism with coronary artery spasm during cardiac catheterisation in Egyptians.
Background: Coronary artery spasm is among the etiology of myocardial infarction. Oxidative stress is involved in the pathogenesis of coronary artery spasm (CAS). Paraoxonase-1 (PON1) is an HDL-bound antioxidant enzyme that protects LDL from oxidative modification. Oxidative-stress-related genetic factors and certain polymorphisms in the paraoxonase 1 gene might influence the pathogenesis of CAS. We aimed to investigate the association between PON1 gene polymorphism and its enzymatic activity and coronary artery spasm during cardiac catheterization.
Methods and results: The study population was 150 patients who underwent elective coronary angiography. Subjects were genotyped to the Q192R polymorphism (rs662) on the PON1 gene by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), and PON1 activity was quantitatively analyzed by enzyme linked immunosorbent assay. Results showed that the subjects carrying the RR genotype and R allele were significantly more likely to develop coronary artery spasm (OR=4.2, 2.03, P< 0.006, P˂0.02, respectively). Moreover, serum PON1 levels were significantly decreased (P˂0.001) in the CAS group. RR genotype of PON1 Q192R polymorphism, Tc, LDLc, TG, catheter size, and paroxonase-1 serum level are independent predictors of coronary spasm.
Conclusion: We conclude that the PON1 (rs662) gene polymorphism is associated with CAS during cardiac catheterization in Egyptians. The PON1-192R allele and lower serum enzyme concentration may play an important role in coronary spasm.
期刊介绍:
Archives of Physiology and Biochemistry: The Journal of Metabolic Diseases is an international peer-reviewed journal which has been relaunched to meet the increasing demand for integrated publication on molecular, biochemical and cellular aspects of metabolic diseases, as well as clinical and therapeutic strategies for their treatment. It publishes full-length original articles, rapid papers, reviews and mini-reviews on selected topics. It is the overall goal of the journal to disseminate novel approaches to an improved understanding of major metabolic disorders.
The scope encompasses all topics related to the molecular and cellular pathophysiology of metabolic diseases like obesity, type 2 diabetes and the metabolic syndrome, and their associated complications.
Clinical studies are considered as an integral part of the Journal and should be related to one of the following topics:
-Dysregulation of hormone receptors and signal transduction
-Contribution of gene variants and gene regulatory processes
-Impairment of intermediary metabolism at the cellular level
-Secretion and metabolism of peptides and other factors that mediate cellular crosstalk
-Therapeutic strategies for managing metabolic diseases
Special issues dedicated to topics in the field will be published regularly.
