Cell caspase-9 activity. CK means case-control with medium. As LA was dissolved in 0.1 N NaOH, NaOH group means case-control with reagent. A, B, C, and D were four different treatments of the three cell lines. For HUVEC: A = 200 μM without LA pre-treatment, B = 400 μM without LA pre-treatment, C = 200 μM with 100 μM LA pre-treatment, D = 400 μM with 100 μM LA pre-incubation, For LOVO and RKO cells: A = 100 μM without LA pre-treatment, B = 300 μM without LA pre-treatment, C = 100 μM with 100 μM LA pre-treatment, D = 300 μM with 100 μM LA pre-incubation. Each treatment was carried out in triplicate and repeated at least twice. *p < 0.05, and **p < 0.01.
