Abstract
Amaç: Çalışmada, adriamisin (ADR) uygulanan sıçanların böbrek dokularında meydana gelen değişiklikler üzerine alfa lipoik asit (ALA)’nın korucu
etkisinin dinamin bağımlı protein 1 (DRP1) ile ilişkisinin incelenmesi amaçlanmıştır.
Gereç ve Yöntem: Çalışmada, 28 adet Sprague-Dawley cinsi erkek sıçanlar kullanıldı. Deney hayvanları 4 eşit gruba ayrıldı. Kontrol grubuna deney
süresi olan 28 gün boyunca hiçbir uygulama yapılmadı. ADR grubuna; 15 mg/kg ADR intraperitoneal (i.p) tek doz uygulandı. ADR+ALA grubuna 15
mg/kg i.p tek doz ADR verilmesinden sonra 50/mg/kg/gün dozunda ALA oral olarak gün aşırı verildi. ALA grubuna ise 50 mg/kg/gün dozunda ALA
oral olarak gün aşırı uygulandı. Deney sonunda sıçanlar dekapite edildi. Dekapitasyonun ardından böbrek dokuları hızla çıkarıldı ve histolojik ve
kantitatif RT-PCR analizleri için kullanıldı.
Bulgular: ADR grubuna ait böbrek kesitlerinde inflamatuar hücre artışı, bowman boşluğunda artış, tübül lümeninde hiyalin birikimi gibi yapısal
değişikliklere rastlandı. ALA uygulaması ile histopatolojik bulguların büyük bir çoğunluğunda azalma gözlendi. ADR grubunda DRP1 immünreaktivitesinin
kontrol grubuna göre anlamlı artış gösterdiği, ADR+ALA grubunda ise ADR grubuna göre anlamlı derecede azalma olduğu belirlendi.
Kontrol grubuna kıyasla ADR grubunda DRP1, BAX ve CASP3 mRNA düzeylerinde istatistiki açıdan anlamlı bir artış tespit edildi. ADR+ALA
grubunda ise ADR grubuna kıyasla DRP1, BAX ve CASP3 mRNA düzeylerinde anlamlı bir azalma tespit edildi.
Sonuç: Bu çalışma ADR’nin böbrek dokularında yapısal hasarla birlikte apoptozis ve DRP1 ekspresyon artışına yol açtığı, ALA’nın apoptozis ve
DRP1 aktivitelerini düzenleyerek ADR’nin bu zararlı etkilerine karşı büyük oranda koruma sağladığı ortaya koyuldu.
Objective: In this study, we aimed to investigate the association with DRP1 the protective effect of ALA on kidney tissue of the rats administered with adriamycin. Material and Method: Twenty eight Sprague-Dawley male rats were used in this study. Animals were divided to four groups. No administration was made to the control group during 28 days. A single dose of 15 mg / kg ADR was given intraperitoneally to the ADR group. After 15 mg / kg ADR was given to ADR + ALA group, 50 mg / kg ALA was given by oral gavage every other day. In the ALA group, 50 mg / kg ALA was administered orally every other day. At the end of the experiment, the rats were decapitated. Following decapitation, histological and quantitative RT-PCR analyzes were done. Results: Histopathological findings such as inflammatory cell increase, enlargement bowman distance were observed in the ADR group. ALA treatment was found to reduce the majority of histopathological findings.DRP1 immunoreactivity was significantly increased in the ADR group compared to the control group, whereas in the ADR+ALA group, DRP1 immunoreactivity was significantly lower than ADR group. A statistically significant increase was found in DRP1, BAX and CASP3 mRNA levels in the ADR group compared to the control group. A significant decrease was detected in DRP1, BAX and CASP3 mRNA levels in ADR + ALA group compared to the ADR group. Conclusion: This study revealed that ADR causes apoptosis and increases in DRP1 expression together with histopathological damages in kidney tissues, whereas ALA provides major protection against these effects of ADR by regulating apoptosis and DRP1 activities.
