The task is to decide the Hallmarks of Cancer (HOC) taxonomy of the article based on its abstract. The input is an abstract text. There are 10 topics you will need to decide whether the article is related to. Topics: sustaining proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, activating invasion and metastasis, genomic instability and mutation, tumor promoting inflammation, cellular energetics, avoiding immune destruction. The output should be topics from the above 10 topics, that are related to the input article. Please note one article can be related to multiple topics. Output format: provide a semicolon-separated list of relevant topics.

    INPUT: PURPOSE Idarubicin is a synthetic anthracycline anticancer drug widely used in the treatment of some hematological malignancies . The studies in our laboratory have clearly demonstrated that idarubicin can undergo reductive bioactivation by NADPH-cytochrome P450 reductase to free radicals with resulting formation of DNA strand breaks , which can potentially contribute to its genotoxic effects [ Celik , H. , ArinÃ§ , E. , Bioreduction of idarubicin and formation of ROS responsible for DNA cleavage by NADPH-cytochrome P450 reductase and its potential role in the antitumor effect . J Pharm Pharm Sci , 11(4):68-82 , 2008 ] . In the current study , our aim was to investigate the possible protective effects of several phenolic antioxidants , quercetin , rutin , naringenin , resveratrol and trolox , against the DNA-damaging effect of idarubicin originating from its P450 reductase-catalyzed bioactivation . METHODS DNA damage was measured by detecting single-strand breaks in plasmid pBR322 DNA using a cell-free agarose gel method . RESULTS Our results indicated that , among the compounds tested , quercetin was the most potent antioxidant in preventing DNA damage . Quercetin significantly decreased the extent of DNA strand breaks in a dose-dependent manner ; 100 microM of quercetin almost completely inhibited the DNA strand breakage . Unlike quercetin , its glycosidated conjugate rutin , failed to provide any significant protection against idarubicin-induced DNA strand breaks except at the highest concentration tested ( 2 mM ) . The protective effects of other antioxidants were significantly less than that of quercetin even at high concentrations . Quercetin was found to be also an effective protector against DNA damage induced by mitomycin C. CONCLUSION We conclude that quercetin , one of the most abundant flavonoids in the human diet , is highly effective in reducing the DNA damage caused by the antitumor agents , idarubicin and mitomycin C , following bioactivation by P450 reductase .
