Effects of honokiol on the apoptosis of THP-1, U-937, and SKM-1 cells. The cells were incubated with the indicated concentration of honokiol for 24 h, and Annexin-V-FITC/PI staining and flow cytometry analysis were performed. The experiments were performed in triplicate. Statistical analysis of cell apoptosis was shown as bar graphs (*, p < 0.05, **, p < 0.01, compared to the control group).
