Abstract

Background: Aortic aneurysm occurs in the thoracic and abdominal sections of the aorta and is a deadly late-ageat-onset disease. Thoracic aortic aneurysms (TTAs) are characterized by progressive smooth muscle cell rarefaction due to impaired extracellular matrix. The aim of this study was to investigate fibrillin-1 (FBN-1), fibronectin-1 (FN-1) and tissue inhibitors of metalloproteinases-3 (TIMP3) gene expression levels in patients with TTA.Materials and methods: The data were analyzed for 16 patients treated for TAA and nine control subjects. Tissue samples obtained during surgery were frozen immediately in liquid nitrogen and stored at −80°C until RNA isolation. Gene expression analysis was performed by quantitative reverse transcription polymerase chain reaction for each gene and Beta actin was used as control gene. 2−ΔΔCT method was used for the determining expression levels of the genes.Results: According to the results of this study, TIMP-3 gene was nine-fold higher expressed in TAA tissues (p = 0.034). Furthermore, TIMP-3 expression levels were found associated with fasting blood glucose, red blood cells and ejection fraction. The gene expression levels of FBN-1 and FN-1 were not statistically significant (p > 0.05).Conclusion: In this clinical trial, we concluded that TIMP-3 expression increases in dilated aorta.

Özet

Amaç: Aort anevrizması aortun torasik ve abdominalbölümlerinde meydana gelir ve ölümcül, bir ileri yaşatak hastalığıdır. Torasik Aort Anevrizma (TAA) ilerle yen düz kas hücresi azalmasına bağlı olarak ekstrasellü ler matriksin yıkımı ile karakterize edilir. Bu çalışmadaTorasik Aort Anevrizmalı hastalarda fibrillin1 (FBN-1),fibronektin-1 (FN-1) ve metalloproteinaz doku inhibi törü-3 (TIMP-3) gen ekspresyon seviyelerinin araştırıl ması amaçlanmıştır. Gereç ve Yöntem: Çalışmamıza 16 TAA’lı olgu örneği ve 9kontrol örneği dâhil edildi. Ameliyat sırasında alınan dokuörnekleri sıvı nitrojen içerisinde dondurularak RNA izolas yonu yapılana kadar −80°C derin dondurucuda saklandı.Kontrol geni olarak beta aktin kullanıldı. Gen ekspresyonanalizi qRT-PCR metodu kullanılarak yapıldı. 2−ΔΔCT metodugen ekspresyon seviyelerinin belirlenmesinde kullanıldı. Bulgular: TIMP-3 geninin TAA dokularında 9 kat fazlaeksprese edildiği bulundu (p = 0,034). Dahası, TIMP-3 eks presyon seviyeleri açlık kan şekeri, kırmızı kan hücrelerive ejeksiyon fraksiyonuyla ilişkili bulundu. FBN-1 ve FN-1gen ekspresyon seviyeleri istatiksel olarak anlamlı bulun madı (p > 0,05). Sonuç: Çalışmamızda genişlemiş olan aortta TIMP3 eks presyonunun arttığı belirlenmiştir.
