Effect of different PS treatments on the growth of hormone-dependent BC cells using MTT assay. (A) The effect of PS treatments on the growth of BT-474 cells over 24 h, 48 h, and 72 h culture period. (B) The effect of PS treatments on the growth of T47D cells after 24 h, 48 h, and 72 h culture period. Cells were treated with vehicle-control or increasing concentrations of PS treatment. Results showed time and dose-dependent inhibition of BC cells viability. Vertical bars indicate mean cell count ± SEM (n = 6) in each treatment group for same culture period time (*p < 0.05, **p < 0.01, ***p < 0.001, and ****p < 0.0001 for statistical significance compared to vehicle-treated controls).
