Abstract

Objective: Neuropeptide Y (NPY) is a protein widely expressed in the central nervous system and involved in diverse physiological processes, such as emotional regulation, nutritional behavior, and stress. In some populations, studies on alcohol dependence (AD) and the NPY gene have found that NPY variations increase alcohol consumption and thus may potentially be associated with AD. In this study, we investigated the relationship between NPY gene promoter polymorphisms and phenotypes related to alcohol use. Method: A total of 417 male participants comprising 252 individuals with AD and 165 healthy individuals were included in this study and phenotypic data were collected. Polymerase chain reaction-restriction fragment length polymorphism (PCR/RFLP) and DNA sequencing methods were used for genotyping the rs16147 and rs17149106 polymorphisms in the promoter region of the NPY gene. The data of 384 participants were analysed to evaluate the possible relationship between genotypes and the diagnosis of AD, family history of AD, the severity of AD using the Michigan Alcoholism Screening Test (MAST), the age of onset of problematic alcohol use, the average amount of alcohol consumed per day for the last six months and the lifetime maximum alcohol consumption in one day. Results: A significant difference was found between the AD and control groups concerning rs16147 polymorphism genotype distribution (p=0.025). No association with polymorphisms and alcohol-related phenotypes were demonstrated in the AD group. Conclusion: To our knowledge, this study shows for the first time in the literature that alcohol dependence is associated with NPY rs16147 polymorphism in the Turkish population.

Özet

Amaç: Nöropeptid Y (NPY), merkezi sinir sisteminde yaygın olarakifade edilen; duygusal düzenleme, beslenme davranışı ve stres gibibirçok fizyolojik süreçte yer alan bir proteindir. Bazı toplumlarda, alkolbağımlılığı (AB) ve NPY geni üzerine yürütülen çalışmalarda, NPYvaryasyonlarının alkol tüketimini arttırdığı ve AB ile ilişkili olabileceğibulunmuştur. Bu çalışmada, NPY geni promotor polimorfizmleri ilealkol kullanımına bağlı fenotipler arasındaki ilişki araştırılmıştır.Yöntem: Çalışmaya AB tanısı konulan 252 hasta ve 165 sağlıklı bireydenoluşan toplam 417 erkek katılımcı dâhil edilmiş ve fenotipik verilertoplanmıştır. Polimeraz zincir reaksiyonu–restriksiyon fragman uzunlukpolimorfizmi (PZR/RFLP) ve DNA dizileme yöntemi kullanılarakNPY geninin promotor bölgesindeki iki polimorfizmin (rs16147ve rs17149106) genotiplendirmesi yapılmıştır. Bu çalışmada 384katılımcının verileri, genotipler ve AB tanısı, AB aile öyküsü, MichiganAlkolizm Tarama Testi (MATT) kullanılarak değerlendirilen AB şiddeti,sorunlu alkol kullanımına başlama yaşı, son altı ay için günlük tüketilenortalama ve yaşam boyu bir günde tüketilen maksimum alkol miktarıarasındaki olası ilişkiyi değerlendirmek için analiz edilmiştir.Bulgular: AB ve kontrol grupları arasında, rs16147 polimorfizmigenotip dağılımı açısından anlamlı bir fark bulunmuştur (p=0,025).Ancak hasta grubunda her iki polimorfizmin de alkol kullanımına bağlıfenotipler üzerinde bir etkisi bulunamamıştır.Sonuç: Çalışmamız, Türkiye kökenli bir örneklemde alkol bağımlılığınınNPY rs16147 polimorfizmi ile ilişkili olduğunu gösteren ilk çalışmadır.
