Knockdown of TET1 expression recapitulates effects of homoharringtonine (HHT) treatment in acute myeloid leukemia (AML) cells. (A) Qualitative polymerase chain reaction (qPCR) analysis of TET1 knockdown efficacy in MONOMAC 6, MA9.3ITD and MA9.3RAS cells. (B) Effects of TET1 knockdown on cell growth/proliferation of these three AML cell lines at different time points [0, 24, 48, 72 and 96 hours (h)]. (C) Effects of TET1 knockdown on apoptosis in MA9.3ITD and MA9.3RAS AML cells. (D) Statistical analysis of apoptosis assay in AML cells from three independent experiments determined by flow cytometry. (E) Effects of TET1 knockdown on cell cycle arrest in AML cells. (F) Statistical analysis of cell cycle assays from three independent experiments determined by flow cytometry. (G) Statistical analysis of cell proportions of CD11b+CD14+ and CD11bCD14 in TET1 knockdown or control MONOMAC 6 cells. (H) HHT IC50 in MA9.3ITD and MA9.3RAS cells with or without TET1 knockdown. These cells were exposed to HHT for 72 h. *P<0.05; **P<0.01; ***P<0.001; t-test. Error bar, mean±Standard Deviation.
