Abstract

Purpose: The aim of this study is to investigate the apoptotic effect of a novel anti-cancer drug, ceranib-2 and impact on HIF-1α levels on HepG2.
Materials and Methods: The cell line was treated in vitro with 0,1, 1, 5, 10, 25 and 50 µM ceranib-2 for 24 and 48 hours and cell viabilitiy was determined. mRNA levels of acid ceramidase, caspase-3, caspase-8, caspase-9, Cyc1, HIF-1α and TNF-α were measured by qPCR.
Results: Ceranib-2 at 10 µM concentration reduced the viability by about 58 % after 24 and 48 hours. The same dose increased mRNA level of caspase-3 and no change was detected on caspase-8 when compared to the control group after 24 hours. No difference was detected on caspase-3, but caspase-8 mRNA level increased after 48 hours with ceranib-2 at 10 µM concentration. Caspase-9 mRNA levels did not differ after 24 and 48 hours. Ceranib-2 at 10 µM concentration lowered mRNA level of Cyc1 against the control group after the 24- hour treatment. ASAH mRNA level was reduced after the 48-hour treatment with 10 µM ceranib-2. Reduction of ASAH indicated that 10 µM ceranib-2 could inhibit ceramidase after 48 hours and this may elavate ceramide concentration. TNF-α mRNA increased after 24 and 48 hours, but HIF-1α expression was low after 24 hours when compared to the control group.
Conclusion: We have found that ceranib-2 induces apoptosis in HepG2, thus ceranib-2 may play an anti-cancer role at 10 µM concentration.

Abstract

Amaç: Bu çalışmanın amacı, yeni bir anti-kanser ilaç olan seranib-2' nin apoptotik etkisini ve HIF-lα düzeylerinin HepG2 üzerindeki etkisini araştırmaktır.
Gereç ve Yöntem: Hücreler 0, 1, 1, 5, 10, 25 ve 50 µM seranib-2 ile 24 ve 48 saat süreyle muamele edildi ve hücre canlılığı belirlendi. Asit seramidaz, kaspaz-3, kaspaz-8, kaspaz-9, Sitokrom C1, HIF-1α,ve TNF-α mRNA seviyeleri qPCR ile ölçüldü.
Bulgular: 10 µM konsantrasyonda Ceranib-2; 24 ve 48 saat tedaviden sonra hücre canlılığını yaklaşık % 58 azalttı. Aynı doz, kaspaz-3'ün mRNA seviyesini arttırdı ve 24 saat sonra kontrol grubuna kıyasla kaspaz-8 üzerinde herhangi bir değişiklik tespit edilmedi. Kaspaz-3'te herhangi bir değişiklik saptanmazken kaspaz-8 mRNA seviyesi, 48 saat sonra 10 µM seranib-2 konsantrasyonunda arttı. Kaspaz-9 mRNA seviyeleri 24 ve 48 saat sonra değişmedi. 10 µM konsantrasyonda Ceranib-2, 24 saatlik tedaviden sonra kontrol grubuna karşı Sitokrom C1'in mRNA seviyesini düşürdü. ASAH mRNA seviyesi, 10 µM seranib-2 ile 48 saatlik tedaviden sonra azaltılmıştır. ASAH' ın azaltılması, 10 µM seranib-2'nin 48 saat sonra seramidazı inhibe edebileceğini ve bunun seramid konsantrasyonunu artırabildiğini gösterdi. TNF-α mRNA seviyesi hem 24 hem de 48 saat sonra arttı, ancak HIF-lα mRNA seviyesi, 24 saat sonra kontrol grubuna kıyasla düşüktü.
Sonuç: Seranib-2' nin HepG2'de apoptozu indüklediğini bulduk, bu nedenle seranib-2’ nin 10 µM konsantrasyonda anti-kanser bir rolü olabilir.
