To evaluate the effects of Cordyceps militaris extract (CME) on angiogenesis and tumor growth.
Human umbilical vein endothelial cells (HUVEC), HT1080, and B16-F10 cells were used. DNA fragment, angiogenic related gene expressions (MMPs, bFGF, VEGF, etc), capillary tube formation, wound healing in vitro, tumor growth in vivo were measured.
CME inhibited growth of HUVECs and HT1080 (P<0.01). CME 100 and 200 mg/L reduced MMP-2 gene expression in HT1080 cells by 6.0 % and 22.9 % after 3-h and 14.9 % and 32.8 % after 6-h treatment. CME did not affect MMP-9 gene expression in B16-F10 melanoma cells. CME 100 and 200 mg/L also reduced bFGF gene expression in HUVECs by 22.2 % and 41.3 %. CME inhibited tube formation of endothelial cells in vitro and in vivo. CME repressed the growth of B16-F10 melanoma cells in mice compared with control group (P<0.05).
CME has antiangiogenetic properties.
