【 摘 要 】
The in vitro study of DNA Adduct 8-OHdG Formation due to BisphenolA (BPA) as xenobiotics has been conducted by using calf thymus DNA and 2'deoxyguanosine. The method of study was conducted by incubating calf thymus DNA and 2'dG with compounds trigger to radicals in the variation of pH (7.4 and 8.4), temperature (37°C and 60°C), and BPA concentrations (2 ppm and 10 ppm). To represent the work of CYP 450 enzyme in metabolic process of xenobiotics in the body and the effect of metal presence to the formation of radicals that can lead to 8-OHdG formation, we used iron(II) solution and also fenton reagent (Fe(II) and H2O2). The DNA used has 1.8 purity ratio (checked at λ260/λ280 by using Spectrophotometry UV-Vis). The results by using HPLC method showed that BPA could interact with DNA and DNA base (represent as calf thymus and 2'dG) and potentially induced 8-OHdG formation. The presence of iron(II) metal and Fenton reagent also induced the higher 8-OHdG formation. The higher of pH, temperature and concentrations also lead to 8-OHdG formation (ranger between 4 - 70 ppb).【 预 览 】
