Anti-miR-93 promotes cell cycle arrest and the apoptosis of AML cells. The expression of miR-93 was upregulated in THP-1 cells and downregulated in HL60 cells. (A) Cell cycle distribution was measured by flow cytometry. (B) Relative cell apoptosis was detected by flow cytometry. (C) Levels of the cycle-related proteins, p21 and cyclin D1, and the apoptosis-related proteins, caspase3, Bax and Bcl-2, were detected by western blot analysis. (D) Representative images of Hoechst 33258 staining. Each experiment was performed 3 times, independently. Data are presented as the means ± standard deviation. Data in (A-C) were analyzed by one-way ANOVA, followed by Tukey's multiple comparisons test. *P<0.05, compared with the control group; #P<0.05, compared with the oe-NC or anti-NC group. miR-93, microRNA-93; NC, negative control; AML, acute myeloid leukemia.
