Polygonum cuspidatum Extract Induces Anoikis in Hepatocarcinoma Cells Associated with Generation of Reactive Oxygen Species and Downregulation of Focal Adhesion Kinase
Figure 6
PCE inhibited FAK expression in Bel-7402 cells. (a) Adherent growth Bel-7402 cells (Adh) and PCE-treated suspension-cultured Bel-7402 cells were collected and subjected to western blots using antibody against FAK and Phospho-FAK (pFAK). (b) Bel-7402 cells were transfected with recombinant human FAK and empty vector and subjected to suspension-culture, PCE (200 μg/mL) treatment and anoikis assay. At the same time, FAK expression was determined by western blot (c). GAPDH was used as a loading control. **, versus control group; #, re-FAK groups versus PCE-treated empty vector group.
