Effect of AL on proliferation inhibition and apoptosis induction in colorectal cancer in vitro. A, AL significantly suppressed the proliferation of both SW620 and HCT116 cell lines evaluated by MTT assay as described under “Materials and methods”. B, Degree of AL-induced apoptosis in SW620 cell lines were determined by Live/Dead assay. Data are presented as relative increase in apoptosis of treated cells compared with untreated control cells. Similar results were obtained in three independent experiments.*, P < 0.05; **, P < 0.01 vs. control.
