MLL fusion proteins regulate Bex2 expression. In presence of 4-OHT (100 nM) MLL-ENL-ERtm mouse cell lines expressed MLL-ENL and Bex2. Withdrawal of 4-OHT for seven to nine days induced downregulation of MLL-ENL and suppression of Bex2 transcription. Bex2 expression levels with standard deviations were determined in two different MLL-ENL-ERtm cell line clones by quantitative real-time PCR analysis.
