Function of Cu2+ on the DNA-breaking actions of ascorbic acid and triose reductone.
The role of Cu2+ on the DNA-breaking action of ascorbic acid (AsA) and triose reductone (TR) was studied with an agarose slab gel electrophoretic analysis. AsA and TR decomposed calf thymus DNA which had been pretreated with Cu2+, and their decomposing activity was proportional to the concentration of Cu2+ bound to the DNA. The DNA-Cu2+ complex had the ability to oxidize reductones. AsA and TR ...
متن کاملMutagenic action of triose reductone and ascorbic acid on Salmonella typhimurium AT 100 strain.
In order to investigate the functions of reductones, their mutagenic action was studied with and without cupric ion using Salmo nella typhimurium TA 100 strain. Triose reductone (TR), which has the simplest enediol structure among reductones, induced a notable frequency of his+ revertants at 2.5 or 5mM. The addition of cupric ion to TR at a molar ratio of 1:1,000 lowered the most active concent...
متن کاملElectrophoretic study on the DNA-breaking actions of ascorbic acid and triose reductone in the presence of Cu2+.
The mode of DNA-breaking actions of ascorbic acid (AsA) and triose reductone (TR) in the presence of Cu2+ was studied by use of 0.8% agarose slab gel electrophoretic analysis. The DNA-breaking actions of the mixture of AsA or TR and Cu2+ were inhibited by N2 gas, hydroxyl radical scavengers and catalase, indicating that the oxidation of AsA or TR by Cu2+ and the hydrogen peroxide and hydroxyl r...

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
