Abstract

Objective: This study aimed to investigate the effect of high-fructose and high-fat diets on advanced glycation end products (AGE) and their receptors (RAGE) in rat liver immunohistochemically and ultrastructurally. Materials and Methods: Rats were divided into three groups as the control group, high-fructose group, and high-fat group. The high-fructose group was given 60% fructose diet, and the highfat group was fed 45% fatty diet. After 12 weeks, rats were sacrificed, and liver tissues were taken for light and electron microscopic examinations. Expressions of AGE, RAGE, nuclear factor kappa B (NF-κB), and 8–hydroxyguanosine (8-OhdG) were detected immunohistochemically. Liver function enzymes, namely, aspartate transaminase, alanine transaminase, alkaline phosphatase, and gamma-glutamyl transferase, were measured from serum samples. Results: Prominent degenerative changes were detected in the liver sections of both diet groups. Immunostaining of AGE, RAGE, NF-κB, and 8-OHdG was more evident than that of the control group. Activities of the liver function enzymes of these groups were higher than those of the control group. Ultrastructurally, accumulations of glycogen and lipid droplets in hepatocytes were observed in the diet groups. Conclusion: High-fructose and high-fat diets can cause ultrastructural changes in the liver, and the damage can be related with increased AGE.

Özet

Amaç: Bu çalışma, sıçan karaciğerinde ileri glikasyon son ürünleri (AGE) ve reseptörleri (RAGE) üzerine yüksek fruktozlu ve yüksek yağlı diyetlerin etkisini immünohistokimyasal ve ultrastrüktürel olarak araştırmayı amaçlamıştır. Gereç ve Yöntem: Sıçanlar kontrol grubu, yüksek fruktoz grubu ve yüksek yağlı grup olarak üç gruba ayrıldı. Yüksek fruktozlu gruba%60 fruktozlu diyet, yüksek yağlı gruba ise %45 yağlı diyet uygulandı. 12 hafta sonra, sıçanlar sakrifiye edildi ve ışık ve elektron mikroskobik incelemeler için karaciğer dokuları alındı. AGE, RAGE, nükleer faktör kappa B (NF-κB) ve 8-hidroksiguanozin (8-OhdG) ekspresyon düzeyleri immünohistokimyasal olarak tespit edildi. Serum örneklerinden aspartat transaminaz, alanin transaminaz, alkalin fosfataz ve gama-glutamil transferaz gibi karaciğer fonksiyon enzimleri ölçüldü. Bulgular: Her iki diyet grubunun karaciğer dokularında belirgin dejeneratif değişiklikler saptandı. AGE, RAGE, NF-κB ve 8-OHdG’nin immün boyanması, kontrol grubuna göre daha belirgindi. Bu grupların karaciğer fonksiyon enzim aktiviteleri, kontrol grubuna göre daha yüksekti. Ultrastrüktürel olarak diyet gruplarında hepatositlerde glikojen ve lipid damlacıklarının birikimleri gözlendi. Sonuç: Yüksek fruktozlu ve yüksek yağlı diyetler karaciğerde ultrastrüktürel değişikliklere neden olabilir ve artmış hasar AGE ile ilişkili olabilir.
