Isobavachalcone Induces ROS-Mediated Apoptosis via Targeting Thioredoxin Reductase 1 in Human Prostate Cancer PC-3 Cells

Figure 2

Effect of IBC treatment on PC-3 cell morphology and apoptosis. Cells were exposed to 15, 30, or 45 μM IBC for 24 h. (a) After treating cells for 24 h, the morphology of PC-3 cells was visualized and imaged by inverted phase contrast microscopy. (b) The morphological changes in PC-3 cells were examined following staining with Hoechst dye 33258. (c) Rate of apoptotic cells of IBC-treated PC-3 cells as detected by flow cytometry. (d) Quantitative analysis of the rate of apoptotic cells after IBC treatment. All data are presented as mean ± S.D. and compared with the control group.
