Polygonum cuspidatum Extract Induces Anoikis in Hepatocarcinoma Cells Associated with Generation of Reactive Oxygen Species and Downregulation of Focal Adhesion Kinase
Figure 2
PCE inhibited colony formation of hepatocarcinoma cells in soft agar. Bel-7402 cells (a) and Hepa 1–6 cells (b) were treated with different dose of PCE twice a week for 2 weeks in the soft-agar colony formation assay. The colonies were stained and counted. Data shown are representative of three independent experiments (each conducted in triplicate). **, versus control group.
