Objective To explore the role of Nrf2/EZH2 in mediating erythroid differentiation in mouse erythroleukemia cells under DMSO exposure. Methods MEL cells were treated with DMSO. Erythroid differentiation was detected by bezidine staining. The expression levels of Nrf2 and EZH2 were determined by western blotting. Results DMSO induced erythroid differentiation in MEL cells,along with significant induction of Nrf2 and EZH2 expression. TBHQ,a selective Nrf2 activator,increased the protein level of Nrf2.Interestingly,TBHQ also induced EZH2 expression. The lentiviral particle containing Nrf2 short hairpin RNA( shRNA) efficiently blocked TBHQ-induced EZH2 levels. Moreover,Nrf2 or EZH2 shRNA significantly inhibited DMSO-induced erythroid differentiation. Conclusion Nrf2 induction is involved in MELerythroid differentiation under DMSO exposure by regulating EZH2.
