| Abstract : Polydatin, also called piceid, is a stilbenoid glucoside of a resveratrol derivative. It derives mainly from the root and rhizome of Polygonum cuspidatum Sieb. et Zucc. Although the role of P. cuspidatum root in angiogenesis has been reported, the active chemical or chemicals responsible for such function is not known. Here, polydatin was proposed to bind VEGF, which therefore altered the functions of VEGF in angiogenesis. Several lines of evidence supported the pharmaceutical effects of polydatin in VEGF-induced angiogenesis. In human umbilical vein endothelial cells, polydatin inhibited VEGF-stimulated cell proliferation, cell migration, and tube formation. Moreover, polydatin showed suppressive effects on the subintestinal vessel formation in zebrafish embryos. In signaling cascades, polydatin application attenuated VEGF-induced phosphorylations of VEGF receptor 2 and JNK. Moreover, the VEGF-induced phosphorylations of Akt, eNOS, and Erk were significantly decreased in the presence of polydatin. In parallel, the formation of reactive oxygen species, triggered by VEGF, was markedly decreased under polydatin application. Thus, our results supported the angiogenic roles of polydatin, as well as its signaling mechanism in blocking VEGF-mediated responses. The current study provides support for the possible development of polydatin as a potential therapeutic agent for treatment and prevention of angiogenesis-related diseases.-Hu, W.-H., Wang, H.-Y., Kong, X.-P., Xiong, Q.-P., Poon, K.
