Figure 4From: The natural triterpene 3β,6β,16β-trihydroxy-lup-20(29)-ene obtained from the flowers of Combretum leprosum induces apoptosis in MCF-7 breast cancer cells Flow cytometric analysis of cleaved caspase 9 activity. MCF-7 cells were treated with TTHL (IC20 = 0.50 μg/mL, IC50 = 1.36 μg/mL, and IC80 = 3.70 μg/mL), fixed, permeabilized, and stained with anti-active caspase 9. Results are expressed as means ± standard deviation (SD). Data were analyzed by one-way analysis of variance (ANOVA), and means were compared using Tukey test, with P ≤ 0.05 considered as statistically significant.Back to article page
