Expression level of key apoptosis pathway genes in the HT-29, Caco-2, and KDR/293 cancer cells lines after treatment with BHE, betanin, and 5-FU (105 μL/well of 6-well plate) as positive control group for 48 h incubation. Target genes were normalized to GAPDH as housekeeping control gene (*p ≤ 0.05, **p ≤ 0.01 as compared to control)
