Nuclear staining of LS174T cells with Hoechst 33258. After transfection with the miR-145 mimic or siRNA-DFF45 (50 nM), and subsequent exposure to staurosporine (STA) for 12 h, LS174T cells were stained with Hoechst 33258, and visualized using a fluorescence microscope. (A) MiRNA control-treated group. (B) MiRNA control with STA-treated group. (C) MiR-145 mimic-treated group. (D) MiR-145 mimic with STA-treated group. (E) siRNA control-treated group. (F) siRNA control with STA-treated group. (G) siRNA-DFF45-treated group. (H) siRNA-DFF45 with STA-treated group. (I) Untreated group. (J) STA-treated group. LS174T cells treated with the miR-145 mimic or siRNA-DFF45 showed apoptotic morphology: chromatin condensation. (K) The percentage of cell death was calculated by counting the number of cells with condensed chromatin over the total number of cells. The data represent the mean ± SD of three independent experiments. At least 300 cells were counted for each condition.
