RNAi knockdown of activation-induced cytidine deaminase (AICDA) suppressed the induction of MLL-MLLT3 fusion transcript formation observed with estradiol.     ///    Estradiol also stimulated the generation of MLL-MLLT3 fusion transcripts as seen by RT-PCR.     ///    Estradiol induces gene proximity and MLL-MLLT3 fusion in an activation-induced cytidine deaminase-mediated pathway..
