Abstract
The study aims to explore the effect of 12C6+ ion and X-ray on proliferation, migration, tube formation and MMPS of human microvascular endothelial cells ( HMEC-1 ). Transwell migration experiment showed that the radiation could inhibit the migration of HMEC-1 in sub-lethal dose 24 h after irradiation. Furthermore, the inhibition ability of 12C6+ ion was stronger than that of X-ray. Matrigel experiment indicated that 12C6+ ion suppressed the tube formation of HMEC-1 spontaneously. However, the inhibitory effect of X-ray had no significance. Meanwhile, Gelatin Zymography showed the expression of MMP-2 was inhibited obviously by 12C6+ ion, while X-ray had little effect on the expression of MMP-2. In conclusion, 12C6+ ion is superior to X-ray in adiotherapy of tumor.
