Objective:To study the effect of sulforaphane(SFN) on the growth of human bladder cancer cell and its mechanism in vitro. Method:Morphological characteristics of T24 cell nucleus induced by SFN were observed by AO/EB fluorescein staining .The effect of SFN on the T24 cell cycle was determined by flow cytometry. The expression of TrxR at the transcriptional and translational levels were measured by RT-PCR and Western blot methods respectively. Results:(1) After the cells were treated with 10 ?mol/L and 20 ?mol/L SFN for 24 h and 48 h, nuclear fragmentation and apoptotic body were seen under fluorescence microscope. (2) SFN could block the cell cycle at the G0/G1 phase showed by flow cytometry. Moreover, the treatment of 20 ?mol/L SFN for 48h could cause the appearance of sub-G1 before G0/G1 phase. (3) The expression of TrxR mRNA were increased by the treatment of 10 ?mol/L SFN for 4 h, 10 h,24 h ,compared with the control group. Furthermore ,the treatment with high dose SFN (20 ?mol/L ) for 10h or 24 h could induce the expression of TrxR mRNA more significantly . (4)The expression of TrxR protein in the 10 ?mol/L SFN for 24 h group was augmented compared with the control group , and aftertreatment with 20 ?mol/L SFN for 8 h and 24 h, its expression was significantly higher than that in the control group . Conclusion:SFN can inhibit the growth of T24 cell ,induce apoptosis and arrest T24 cell in G0/G1 phase. Its mechanism is associated with the induction of TrxR both at the transcriptional and translational levels.
