مطالعه پلی‌مورفیسم COX-2-765G →C در بیماران میگرنی

Introduction: Migraine is a common debilitating headache with reversible pain attacks associated with temporal changes in the diameter of head blood vessels. According to the International Classification for the Headache Society, migraineurs are divided into two main categories: migraine with aura and migraine without aura. The present study aimed to investigate the association between COX-2-765G →C genetic polymorphism and the risk of migraine. Methods: In this study, genomic DNAs related to the blood tissues of 100 migraine patients and 100 controls were extracted and purified. The expected region of COX-2 gene was amplified utilizing the appropriative COX-2-765G→C (rs20417) primer in the PCR process. Then, the enzyme digestion was performed using RFLP manner and Aci I restriction enzyme. Moreover, the SPSS software (version 20) was applied in order to analyze the study data. Results: The study results revealed that the frequency of the COX-2-765CC and COX-2-765CG genotypes in migraine cases were significantly higher than those of controls. Conclusion: The study findings demonstrated that COX-2-765G→C polymorphism can increase the risk of migraine susceptibility. However, further studies are necessitated to be conducted on larger samples in different nations in other parts of the world in order to assess the role of COX-2 gene variants in the migraine development.
