Real-time PCR analysis of BAK (a), Bax (b), Bcl-2 (c), and P53 (d) genes expression in groups of the HCT116 cell line by normalizing against the corresponding levels of β-actin,**** shows significant differences of the level of gene expression in the treatment groups compared to the control group, with P < 0.0001. ns means the absence of significant differences in the gene expression level in the treatment groups compared to the control group P > 0.05
