Summary

Background: Migraine is a common debilitating primary headache disorder with current head pain attacks, which contributes to physical activity dysfunctions in chronic pain phase. PGE2 and PGI2 are two important prostaglandins synthesised by COX-2 enzymes, involved in migraine pain signals. COX-2 modulation is essential in treatment and pathogenesis of migraine. This study aimed to investigating the association between COX-2 gene polymorphisms with the risk of migraine susceptibility in migraine patients with related and unrelated parents. Methods: This case- control study was based on 100 migraine patients and 100 non-migraine subjects in Bushehr province, Iran in 2013. Genomic DNA of blood samples was extracted and genotyping of COX-2-765G>C (rs20417) and COX-2-1195A>G (rs689466) gene variants was investigated by PCR-RFLP method. Statistical analyses were accomplished using the SPSS software package. Results: There was a significant differences in the frequencies of the COX-2-765G>C and COX-2-1195A>G genotypes between migraine patients and controls (P≤0.05). Conclusion: COX-2-765CC, COX-2-765CG, COX-2-1195GG and COX-2-1195AG genotypes can increase the risk of migraine significantly. As the first study in Iran, we are hopeful to achieve greater results about the relevancy of COX-2 gene, migraine and pain signals pathway by repeating these experiments on more samples.
