Chromosomal breakage resulting from stabilization of DNA topoisomerase II covalent complexes by epipodophyllotoxins may play a role in the genesis of leukemia-associated MLL gene translocations. We investigated whether etoposide catechol and quinone metabolites can damage the MLL breakpoint cluster region in a DNA topoisomerase II-dependent manner like the parent drug and the nature of the dama...
Doxorubicin, a DNA-intercalator, is one of several anti-cancer drugs that have been found to stabilizes topoisomerase II cleavage complexes at drug-specific DNA sites. The distribution and DNA sequence environments of doxorubicin-stabilized sites were determined in the SV40 genome. The sites were found to be most concentrated in the major nuclear matrix-associated region and nearly absent in th...
The nearly 600 proteases in the human genome regulate a diversity of biological processes, including programmed cell death. Comprehensive characterization of protease signaling in complex biological samples is limited by available proteomic methods. We have developed a general approach for global identification of proteolytic cleavage sites using an engineered enzyme to selectively biotinylate ...
