Abstract:

OBJECTIVE: To investigate the effect of nordihydroguaiaretic acid (NDGA) on the migration of endothelial cells (ECs) induced by glioma cells (GCs) in vitro.

METHODS: Cells of human umbilical vein endothelial cell line ECV-304 and human malignant glioma cell line SHG-44 were co-cultured in the Falcon Cell Culture Insert system, and the effect of NDGA on the migration of ECs induced by GCs was investigated. The expression of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) was examined with immunohistochemistry.

RESULTS: The expressions of VEGF and bFGF in SHG-44 cells were reduced after treatment with 100 micromol/L NDGA for 1 to 3 days. 100 micromol/L NDGA significantly inhibited not only the chemotactic migration of ECs induced by either glioma cells or glioma-conditioned media, but also the random motility of ECs (P<0.01). NDGA at a concentration between 50 micromol/L and 200 micromol/L inhibited the chemotactic migration of ECs in a dose-dependent manner (the inhibition ratios were 12.0%, 37.4%, 86.7% and 82.2%).

CONCLUSION: The results confirm the inhibitory effects of NDGA on the migration and angiogenic factor expression of ECs, which suggests that NDGA may suppress angiogenesis of glioma.
