ABSTRACT
Objective To investigate the effect of the new polyamine analogue tetrabutyl propanediamine (TBP) on cell proliferation and the underlying mechanism. Methods MTT assay was performed to determine cell proliferation. Flow cytometry was performed to detect cell cycle transition. DNA fragmentation and mitochondrial membrane potential determinations were performed to detect cell apoptosis. The activity of key enzymes in polyamine catabolism was detected by chemiluminescence assay. Results TBP could significantly inhibit the proliferation of HL-60 cells by blockingcell cycle transition and by inducing apoptosis. The TBP-induced apoptosis of HL-60 cells was in a dose-dependent manner. The enzyme activities of SMO and APAO were also significantly increased in HL-60 cells after treatment with 100 μM TBP for 24 hours. Conclusions TBP, as a new putrescine analogue, could inhibit proliferation of HL-60 cells by increasing the enzyme activity of SMO and APAO and inducing apoptosis.
