We investigated the antiangiogenic effects of Lindera obtusiloba Blume (Hwangmaemok, HMM), which is a plant in the Lauraceae family that is commonly used to treat colds and gastritis. Moreover, given that a recent study reported the inhibitory effects of HMM extract on cancer metastasis, we hypothesized that HMM extract might possess and antiangiogenic function. Thus, this study was conducted to investigate the effects of HMM extract on endothelial cell proliferation, migration, and neovascularization in chick chorioallantoic membrane (CAM), and investigated the molecular mechanism of antiangiogenesis using a ProteoChip-based proteomics technology. To examine the effects of HMM extracts on endothelial cell proliferation and migration, we conducted basic fibroblast growth factor (bFGF)-induced human umbilical vein endothelial cell (HUVEC) proliferation and migration. To assess the molecular mechanism of the antiangiogenic effects of HMM extract, a ProteoChip-based forwarded phase antibody array was employed to identify the differential expression of cell cycle proteins in HMM-treated HUVECs. HMM extract inhibited bFGF-induced HUVEC proliferation and migration in a dose-dependent manner and CAM angiogenesis. The ProteoChip-based antibody microarray data showed upregulation of Nibrin/NBS1 and downregulation of Plk-1 and Cyclin E, which are involved in cell division and controlling the cell cycle in bFGF-induced HUVECs. These data suggest that HMM may be a potent antitumor medicinal herb. The present study demonstrates that the antiangiogenic effect of HMM may be due to suppression of endothelial cell proliferation and migration. Taken together, these results emphasize the potential to use HMM extract as a potent angiogenesis inhibitor to treat cancer.
