We employed a pFZD7-GFP reporter to determine the influence of the Frizzled-7 promoter on the human cancer cell lines HepG2 (liver), 7721 (liver), A549 (lung), SGC7901 (stomach), MCF7 (breast), DU145 (prostate), HEP2 (throat), and normal human cell line (L02, GES-1) after 48 h transfection. This evidence concerns the gene FZD7 and cancer.
