FOXF2 and gastric cancer: Moreover, by performing qPCR on four types of GC cells, namely MKN-45, SGC-7901, MGC-803, BGC-823, and the normal gastric tissue cell line GES-1 and 25 pairs of GC tissues and adjacent normal tissues, we determined that the expression of FOXF2 is significantly downregulated in GC cells and tissues (Figures 1F,G).
