Abstract

Metal-based compounds have been used for a long time because of their potential effects and low toxicity. Metal compound cisplatin has been used medically against various types of cancer and has shown side effects. In present study, we researched the effects of titanium dioxide, which is considered as an alternative agent against cisplatin on the A549 cells and its apoptotic mechanism were investigated. The antiproliferative effects of titanium dioxide were determined using MTT viability analysis depending on the time and concentration intervals at 24, 48 and 72 hours. We assessed that titanium dioxide induced apoptosis. The IC30 concentration of titanium dioxide triggered early and late apoptosis for 72 hours in A549 cells. The IC30 concentration of titanium dioxide was shown to induce apoptosis by reducing mitochondrial membrane potential for 72 hours. However, caspase-3 activity was not observed. The IC30 concentration of titanium dioxide revealed an increase in apoptotic index with immunocytochemical analysis of hematoxylin and eosin, TUNEL, BrdU, Bcl-2 and Bax for 72 hours. The apoptotic structures were scanned by using confocal and TEM microscopy in A549 cells for 72 hours. These results show that titanium dioxide induce antiproliferative and apoptotic effects on A549 cells and that titanium dioxide may be a potential chemotherapeutic agent like cisplatin

Özet

Metal temelli bileşikler potansiyel etkilerinden ve az toksisiteye neden olduklarından dolayı uzun zamandır kullanılmaktadır. Metal bileşik sisplatin çeşitli kanser türlerine karşı tıbbi olarak kullanılmış ve yan etkiler göstermiştir. Bu çalışmada sisplatine alternatif ajan olarak düşünülen titanyum dioksitin A549 hücreleri üzerindeki etkileri ve apoptotik mekanizması araştırıldı. Titanyum dioksitin 24, 48 ve 72 saatlik sürelerdeki zamana ve konsantrasyon aralığına bağlı olarak antiproliferatif etkileri MTT canlılık analizi kullanılarak belirlendi. Titanyum dioksitin apoptozisi tetiklediği saptandı. Titanyum dioksitin IC30konsantrasyonu, 72 saat süresince A549 hücreleri üzerinde uygulandığında erken ve geç apoptozisi tetiklediği belirlendi. Titanyum dioksitin IC30 konsantrasyonu, 72 saat süresince A549 hücreleri üzerine uygulandığında mitokondriyal membran potansiyelini azaltarak apoptozisi tetiklediği gösterildi. Buna rağmen kaspaz-3 aktivitesi gözlenmedi. Titanyum dioksitin IC30konsantrasyonun 72 saatlik süre sonundaki hematoksilen ve eozin, TUNEL, BrdU, Bcl-2 ve Bax immünositokimyasal analizleri sonucunda apoptotik indekslerinde artış belirlendi. Titanyum dioksitin IC30 konsantrasyonun uygulandığı A549 hücrelerinde 72 saatlik süre sonunda konfokal ve TEM mikroskobisi kullanılarak çeşitli apoptotik yapılar gözlendi. Bu sonuçlar titanyum dioksitin A549 hücreleri üzerinde antiproliferatif ve apoptotik etkilerini ve sisplatine eş potansiyel kemoterapötik bir ajan olabileceğini göstermektedir
