Abstract

ABSTRACT Objective: Epilepsy is a neurological disease characterized by recurrent seizures. Cryptogenic cases are those where there are no prior signs of brain damage and no clear etiology. The absence of an obvious causative pathology creates challenges in the clinical management of the disease. Gene expression studies aid in improved clinical care, in terms of providing a better sight into the etiology, or mechanisms of the disease. In this study, we examined the expression levels of IFIT3 and KCNS3 genes in peripheral bloods of cryptogenic epilepsy patients. Methods: Our study included cryptogenic epilepsy patients (n=20) and healthy controls (n=20). The peripheral blood samples of participants were collected, and total RNAs were isolated. Obtained RNA samples were converted into complementary DNAs (cDNAs). Real-Time Quantitative Polymerase Chain Reaction (RT-qPCR) was conducted to measure relative expression levels of IFIT3 and KCNS3 genes. ACTB was assigned as the housekeeping gene. Results: Accordingly, the expression levels of KCNS3 were higher in the patient group (p<0.0001), while IFIT3 levels did not show a statistically significant difference in patients compared to healthy controls. Conclusion: These findings indicate that KCNS3, a potassium channel-related gene, may play a significant role in the pathogenesis of cryptogenic epilepsy. The lack of significant differences in IFIT3 expression further supports the hypothesis that channelopathy, rather than immune-related processes, is a more likely underlying mechanism in these patients.

Özet

Amaç: Epilepsi, tekrarlayan nöbetlerle karakterize edilen bir nörolojik hastalıktır. Kriptojenik vakalar, beyin hasarına dair öncül belirtilerin olmadığı ve belirgin bir etiyolojinin tespit edilemediği durumları ifade eder. Belirgin bir nedensel patolojinin yokluğu, hastalığın klinik yönetiminde zorluklar oluşturmaktadır. Gen ekspresyon çalışmaları, hastalığın etiyolojisi veya mekanizmaları hakkında daha iyi bir bakış açısı sağlayarak klinik bakımın iyileştirilmesine katkıda bulunur. Bu çalışmada, kriptojenik epilepsi hastalarının periferik kanlarında IFIT3 ve KCNS3 genlerinin ekspresyon düzeyleri incelenmiştir. Yöntem: Çalışmamızda kriptojenik epilepsi hastaları (n=20) ve sağlıklı kontrol grubu (n=20) yer aldı. Katılımcılardan periferik kan örnekleri alındı ve total RNA'lar izole edildi. Elde edilen RNA örnekleri, tamamlayıcı DNA'lara (cDNA) dönüştürüldü. IFIT3 ve KCNS3 genlerinin göreceli ekspresyon düzeylerini ölçmek için Gerçek Zamanlı Kantitatif Polimeraz Zincir Reaksiyonu (RT-qPCR) yapıldı. ACTB, referans gen olarak belirlendi. Bulgular: KCNS3 gen ekspresyon düzeyleri hasta grubunda daha yüksek bulundu (p<0.0001), IFIT3 düzeyleri ise sağlıklı kontrollerle karşılaştırıldığında istatistiksel olarak anlamlı bir fark göstermedi. Sonuç: Bu bulgular, potasyum kanalı ile ilişkili bir gen olan KCNS3'ün, kriptojenik epilepsinin patogenezinde önemli bir rol oynayabileceğini göstermektedir. IFIT3 ekspresyonunda anlamlı bir fark olmaması, bu hastalarda bağışıklıkla ilişkili süreçler yerine kanalopatinin daha olası bir mekanizma olduğunu desteklemektedir.
