In addition, Astragalus saponins reportedly can induce stagnation of cell cycle of G2/M phase in gastric cancer cells and promote the down-regulation of the angiogenic protein vascular endothelial growth factor (VEGF) and metastatic proteins metalloproteinase (MMP), thus inhibiting tumor cell growth (Auyeung et al., 2012). This evidence concerns the gene VEGFA and gastric cancer.
