Fig. 5. Expression levels of unique apoptosis-related proteins in FaDu treated with betulinic acid. FaDu cells were treated with 0, 10, and 20 μM betulinic acid for 24 hr. (A) Expression of apoptosis-related proteins, Bcl-2, Bcl-xl, Bax, Bad, and cleaved caspase-9. (B) Quantitative data in (A) were analyzed using Image J. Data are expressed as the mean standard deviation of three independent experiments compared to the control group. *p<0.05, **p<0.01, ***p<0.001.
