(A) Cell growth was determined after treatment with or without 12.5, 25, and 50 µM sauchinone for 48 h. The cell viability was measured using MTS assay. (B,C) MDA-MB-231 and MTV/TM-011 cells were seeded in 24-well plates (1 × 10³/well). After incubation for 24 h, sauchinone was treated at various concentrations (12.5, 25, and 50 µM) for 10–14 days. Data are presented using triplicate wells per group and statistical significance was determined by one-way ANOVA. *, P < 0.05; ***, P < 0.001; NS, not significant.
