Abstract
Objective: Epicatechin (EC) is one of the major components of green tea catechins. This study investigated the effect of the amount of epicatechin obtained by brewing green tea under optimal conditions against oxidative stress induced by hydrogen peroxide (H2O2).
Materials and Methods: In peripheral blood mononuclear cells (PBMCs), the amount of epicatechin determined by brewing green tea under optimum conditions was applied against 250 µM H2O2 and cell viability was determined by MTT test, total antioxidant status (TAS) and total oxidant status (TOS) were determined by biochemical analysis, apoptosis-related Bax, Bcl2, p53 expression analysis was determined by qRT-PCR method.
Results: The cell viability was significantly higher in the H2O2+EC group than in the H2O2 group (p< 0.001). TOS and TAS were changed considerably in the H2O2+EC group compared to the H2O2 group (p<0.05 and p<0.001, respectively). Bax, p53 expression level decreased in H2O2+epicatechin treated cells compared to H2O2 treated cells (p<0.001 and p<0.01 respectively), while Bcl2 expression level increased in H2O2+epicatechin treated cells compared to H2O2 treated cells p<0.01).
Conclusion: The results show that the amount of epicatechin obtained from brewing green tea under optimum conditions has a protective effect on PBMCs against H2O2 induced oxidative stress. Specifically, it was concluded that epicatechin increased cell viability, decreased oxidative stress markers and modulated the expression of key apoptosis-related proteins, thus promoting cell survival.

Abstract
Amaç: Epikateşin (EC) yeşil çay kateşinlerinin ana bileşenlerinden biridir. Bu çalışmada, yeşil çayın optimum koşullarda demlenmesiyle elde edilen epikateşin miktarının hidrojen peroksit (H2O2) tarafından indüklenen oksidatif strese karşı etkisi araştırılmıştır.
Materyal ve Metot: Periferik kan mononükleer hücrelerinde (PBMCs), yeşil çayın optimum koşullarda demlenmesi ile belirlenen epikateşin miktarı 250 µM H2O2'ye karşı uygulanmış ve hücre canlılığı MTT testi ile, toplam antioksidan durum (TAS) ve toplam oksidan durum (TOS) biyokimyasal analiz ile, apoptoz ile ilişkili Bax, Bcl2, p53 ekspresyon analizi qRT-PCR yöntemi ile belirlenmiştir.
Bulgular: H2O2+EC grubunda hücre canlılığı H2O2 grubuna göre anlamlı derecede yüksek bulunmuştur (p<0.001). TOS ve TAS, H2O2 grubuna kıyasla H2O2+EC grubunda önemli ölçüde değişmiştir (sırasıyla p<0.05 ve p<0.001). Bax, p53 ifade düzeyi H2O2+epikateşin uygulanan hücrelerde H2O2 uygulanan hücrelere kıyasla azalırken (sırasıyla p<0.001 ve p<0.01), Bcl2 ifade düzeyi H2O2+epikateşin uygulanan hücrelerde H2O2 uygulanan hücrelere kıyasla artmıştır (p<0.01).
Sonuç: Sonuçlar, yeşil çayın optimum koşullar altında demlenmesinden elde edilen epikateşin miktarının H2O2 kaynaklı oksidatif strese karşı PBMC'ler üzerinde koruyucu bir etkiye sahip olduğunu göstermektedir. Spesifik olarak, epikateşinin hücre canlılığını artırdığı, oksidatif stres belirteçlerini azalttığı ve apoptozla ilgili anahtar proteinlerin ekspresyonunu modüle ettiği, böylece hücre sağkalımını desteklediği sonucuna ulaşılmıştır.
