Abstract

Oxidative stress is the state of imbalance between the level of antioxidant defence system and production of reactive oxygen species (ROS) and is involded in the progression of several diseases such as inflammation, cancer, neurodegenerative disorders and cardiovascular diseases. It is suggested that plant polyphenols may act as antioxidants and therefore it has anti-cancer activities. Resveratrol (RV), is a naturally occuring polyphenolic compound which is found in many plant species including grapes, nuts, blueberries and raspberries. Data indicated that it has anti-oxidant, anti-inflamatory and anti-cancer activities. But there are also some studies reported that RV has not protective effects aganist cancer. In this study, the cytotoxicity of RV in human breast adenocarcinoma (MDA-MB 231), human cervical cancer (HeLa) and Chinese hamster lung fibroblast (V79) cells were evaluated by Neutral Red uptake assay (NRU) and MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) assays after incubation at 24 h. We obtained more or the less same results by two cytotoxicity assays. In the concentrations between 2-400 µM, RV seemed not to induce a pronounced cytotoxicity in all cell types. Even at highest concentrations, it showed almost no cytotoxic effects. So the IC50 values were not calculated at the studied concentrations.

Özet

Oksidatif stres, reaktif oksijen bileşiklerinin üretimi ile antioksidan savunma sistemlerinin dengesinin bozulmasını tanımlayan bir terimdir. Oksidatif stres, inflamasyon kanser, nörodejeneratif bozukluklar ve kardiyovasküler hastalıklar gibi birçok hastalığın gelişmesinde rol oynamaktadır. Bitkisel fenolik bileşiklerin antioksidan etkili oldukları ve bu nedenle anti kanser etkileri oldukları öne sürülmektedir. Resveratrol (RV), üzüm, fındık, yaban mersini ve ahududu gibi pekçok bitkisel üründe bulunan, doğal olarak oluşan polifenolik bir bileşiktir. RV'nin antioksidan, antiinflamatuvar ve antikanser etkileri olduğu gösteren çalışmalar bulunmaktadır. Ancak RV'nin özellikle kanserin önlenmesinde koruyucu etkilerinin olmadığını da iddia edilmektedir. Bu çalışmada, insan meme adenokarsinoma (MDA-MB 231), insan servikal kanser (HeLa) ve Çin hamster akciğer fibroblast (V79) hücrelerinde RV'nin sitotoksik etkileri, 24 saat inkübasyon sonrasında Nötral Kırmızı Alım (NKA) ve 3-(4,5-dimetiltiyazol-2-il)-2,5- difeniltetrazolyum bromür (MTT) yöntemleri ile değerlendirilmiştir. Her iki sitotoksisite yönteminde de benzer sonuçlar elde edilmiştir. 2-400 µM aralığında, RV'ün tüm hücre tiplerinde belirgin bir sitotoksik etkisi olmadığı görülmüştür. Hatta en yüksek konsatrasyonlarda bile neredeyse hiç sitotoksik etkileri olmamıştır. Bu nedenle IC50 değerleri, bu konsantrasyonaralığında hesaplanamamıştır.
