Abstract:
:To examine the role of human DNA topoisomerase IIalpha (topo IIalpha) in drug resistance, we selectively inhibited topo IIalpha gene expression in U937 human monocytic leukaemia cells stably transfected with a plasmid that allowed for Zn-mediated conditional expression of a human alpha-topo IIalpha antisense sequence. Expression of topo IIalpha mRNA was reduced to <30%, whereas no significant alteration of topo IIbeta mRNA expression was observed. Under these conditions, drug sensitivity to the topo-II-directed agents, etoposide and daunorubicin, was reduced to approximately 50%, whereas sensitivity to 4-hydroperoxy-cyclophosphamide (4-HC) was not altered. This suggests that a reduced amount of topo IIalpha mRNA may be sufficient for the resistance to topo II inhibitors in leukaemia cells.
