According to the previous reports, baicalein, chlorogenic acid, naringin, vanillin, and naringenin in GLY might play an important role to perform the tumor-suppressing effect: firstly, by reducing VEGF expression of tumor cells, such as baicalein [63]; secondary, the inhibitory effects of chlorogenic acid and vanillin on matrix metalloproteinases activity might be another mechanism to prevent cell migration and invasion [60, 61, 64]; thirdly, another component of GLY, naringenin, was found to inhibit cancer cell proliferation [58], making GLY a potential remedy for leukemia therapy. This evidence concerns the gene VEGFA and leukemia.
