Here, we employed magnetic Fe3O4 nanoparticles (MNP-Fe3O4) to improve the therapeutic effect of HHT and investigated its biological effects. Within a certain range of concentrations, the HHT-MNP-Fe3O4 showed a more enhanced inhibitory effect on the selected myeloid leukemia cell lines than HHT alone. Compared with HHT, HHT-MNP-Fe3O4 could induce more extensive apoptosis in leukemia cells, which also showed more pronounced cell arrests at G0/G1 phase. HHT-MNP-Fe3O4 enhanced antitumor activity by downregulating myeloid cell leukemia-1, which could inhibit the activation of caspase-3 and poly-ADP-ribose polymerase. In vivo experiments using tumor-bearing animal models showed that the mean tumor volume with HHT-MNP-Fe3O4 was significantly smaller than that with HHT alone (193±26 mm3 versus 457±100 mm3, P |
