From: β-sitosterol induces G1 arrest and causes depolarization of mitochondrial membrane potential in breast carcinoma MDA-MB-231 cells

Figure 5

Effect of β-sitosterol (ST) on mitochondrial membrane potential in breast carcinoma cells. MDA-MB-231 cells were treated with DMSO (control) or 60 and 90 μM ST for 24 h. (A) Mitochondrial membrane potential was measured by JC-1 staining and analyzed by flow cytometry as described in Methods. (B) The quantitative data is presented as means of 590 nm/520 nm (P2/P1) emission spectrum. The data shown are mean ± S.E. of triplicate samples for each treatment. #, p < 0.05; *, p < 0.001 compared with control.
