Abstract | OBJECTIVES: METHODS: The cytotoxic activity was investigated using MTT assay. The cell cycle arrest and reactive oxygen species (ROS) accumulation were determined by flow cytometric analysis. The apoptosis induction was assessed using Annexin V/ Propidium Iodide assay. The gene quantification analysis was measured through real-time polymerase chain reaction. KEY FINDINGS:
Arctigenin and matairesinol exhibited significant antiproliferative activity against CCRF-CEM cells after 72 h treatment with IC50 values of 1.21 ± 0.15 μm and 4.27 ± 0.41 μm, respectively. In addition, both lignans arrest CCRF-CEM cells in the S phase. Furthermore, they could induce apoptosis in CCRF-CEM cells in a concentration- and time-dependent manner. Interestingly, the lignans differentially regulated the expression of several key genes involved in apoptosis pathways, including Bax, Bad and caspase-9. Moreover, both lignans could increase ROS levels in CCRF-CEM cells. CONCLUSIONS:
