Topoisomerases resolve torsional stress, while their function in gene regulation, especially during cellular differentiation, remains unknown. Here we find that the expression of topo II isoforms, topoisomerase IIα and topoisomerase IIβ, is the characteristic of dividing and postmitotic tissues, respectively. In embryonic stem cells, topoisomerase IIα(More)
DNA-protein interactions are vital to fundamental cellular events including transcription, replication, DNA repair, and recombination. Thus, their study holds the key to our understanding of mechanisms underlying normal development and homeostasis as well as disease. Transcriptional regulation is a highly complex process that involves recruitment of(More)
