Studies in cancer research show that apoptosis plays a major role in both tumor formation and treatment response. The effects of different doses of Vitamin C, is an antioxidant, on cell proliferation and apoptosis in HepG2 cells were investigated. As an indicator of apoptosis, caspases 1, 3 and 9 enzyme activity and cytochrome c levels were determined at 31,3 mM Vitamin C concentration which reduced the cell viability significantly and at 3,13 mM and 0,313 mM Vitamin C concentrations which show significant increase of cell viability. There were no significant increase in caspases 1, 3 and 9 activity in Vitamin C treated HepG2 cells. However the caspases 3 activity decreased in HepG2 cells treated with 0,313 mM and 31,3 mM Vitamin C (53% and 57%) significantly. No statistic changes was observed in cytoplasmic and mitochondrial cytocrome c levels in HepG2 cells treated with 0,313 mM, 3,13 mM, 31,3 mM Vitamin C. In conclusion, caspases- independented cell death occurs in different doses of Vitamin C applied HepG2 cells. It may be releated to release of some apoptotic proteins from mitochondria to cytosol

Kanser araştırmalarında yapılan çalışmalar, apoptozisin kanser gelişiminde ve tedaviye cevapta önemli rol oynadığını ortaya koymaktadır. Sunulan çalışmada güçlü bir antioksidan olan Vitamin C’nin farklı dozlarının hepatoselüler karsinom hücrelerindeki hücre canlılığına ve apoptotik hücre ölümüne etkileri incelenmiştir. Apoptozis belirteçlerinden, sitokrom c, kaspaz 1, kaspaz 3 ve kaspaz 9 enzim aktiviteleri hücre canlılığında azalmanın olduğu 31,3 mM Vitamin C konsantrasyonu ile hücre çoğalmasında belirgin artışın gözlendiği 0,313 mM ve 3,13 mM Vitamin C konsantrasyonlarında belirlenmiştir. Farklı dozlarda Vitamin C uygulanan HepG2 hücrelerinde kaspaz 1, 3 ve 9 enzim aktivitelerinde istatistik olarak önemli bir artış gözlenmemiştir. Ancak 0,313 mM ve 31,3 mM Vitamin C uygulanan HepG2 hücrelerinde kaspaz 3 enzim aktivitelerinde (%53 ve %57) istatistik olarak önemli azalma meydana gelmiştir. 0,313 mM, 3,13 mM, 31,3 mM konsantrasyonlarda Vitamin C uygulanan HepG2 hücrelerinin sitoplazmik ve mitokondriyal sitokrom c düzeylerinde istatistik anlamda bir değişim gözlemlenmemiştir. Sonuç olarak, farklı dozlarda Vitamin C uygulanan HepG2 hücrelerinde şekillenen hücre ölümü kaspaz bağımsız olarak şekillenmektedir. Meydana gelen hücre ölümü mitokondriden bazı apoptotik proteinlerin sitoplazmaya salınımı ile şekillenen diğer hücre ölüm yolları ile ilişkilendirilmiştir
