From: Ursolic acid induces apoptosis and anoikis in colorectal carcinoma RKO cells
UA activates Caspases. Caspase-3 (a), − 8 (b) and − 9 (c) activities in UA treated RKO cells. d, After pre-incubated with Z-VAD-FMK for 2 h, RKO cells were treated with UA and subjected to apoptosis detection. Bcl-2 and Bax expression in UA treated RKO cells were evaluated by Western blot (e), and analyzed by the Quantity One software (f). *p < 0.05, **p < 0.01, versus control group; #p < 0.05, ##p < 0.01, versus UA group
