Abstract
YM155, a small-molecule survivin suppressant, specifically binds to the transcription factor ILF3, which regulates the expression of survivin[1]. In this experiment we have demonstrated that p54nrb binds to the survivin promoter and regulates survivin expression. p54nrb forms a complex with ILF3, which directly binds to YM155. YM155 induces disruption of the ILF3/p54nrb complex, which results in a different subcellular localization between ILF3 and p54nrb. Thus, identification of molecular targets of YM155 in suppression of the survivin pathway, might lead to development of its use as a novel potential target in cancers.
