Abstract:
Objective: To explore the effect and mechanism of DMDAI-L in inducing the HL-60 cells apoptosis. Methods:Caspase-3 activity in HL-60 cells was measured with the enzymatic visible substrate DEVD-pNA. The fluorescence changes of mito-chondrial membrane potential (△Ψm) in HL-60 cells were investigated with the fluorescent probe JC-1. Results:The caspase-3 activ-ity was significantly increased in HL-60 cells after the DMDAI-L treatment at the concentration of 1. 25, 2. 5, 5, 10 and 20μg·ml-1 for 24h(P<0. 05). DMDAI-L could significantly reduce the mitochondrial membrane potential in HL-60 cells. Conclusion: The mechanism of DMDAI-L in inducing HL-60 cells apoptosis may involve the activation or regulation of caspase-3 activity as well as the reduction of mitochondrial membrane potential in HL-60 cells within certain concentration and time range.
