Abstract:
Objective To investigate the effect and possible mechanism of curcumin on the proliferation and apoptosis of cell strain of bladder carcinoma.Methods In curcumin group,T24 cells were treated with curcumin of 1,10,100 ?mol/L respectively,while no curcumin treatment in control group.The growth,apoptosis,AKT1 protein activity and mRNA level,caspase 3 content of T24 cells were observed by MTT,TUNEL,RT-PCR,immunoblot and image analysis technology 12,24 and 48 h after the commencement of curcumin treatment.Results In the curcumin group,the inhibition rate,apoptosis and the content of caspase 3 of T24 cells increased significantly.The activity of AKT1 protein decreased,but the mRNA level of AKT1 showed no changes.Conclusion Curcumin can inhibit the growth of T24 cells and induce the cell apoptosis,which mechanism is related to the inhibition of AKT1 signal pathway of T24 cells.
