Abstract
This study discussed Astragalus Polysaccharides (APS)’s effect on the cytobiology of glioma. U87 glioma cells were assigned into control group (U87 cells), miR-34a-5p mimic group (transfected with miR-34a-5p mimic), and APS group (treated with 10 μM APS) followed by analysis of miR-34a-5p level, cell proliferation and invasion, Caspase3 and SOD activity as well as E-cadherin, Vimentin and survivn expression. APS treatment significantly upregulated miR-34a-5p expression, inhibits cell proliferation and invasion, and promoted cell apoptosis. In addition, APS also significantly upregulated E-cadherin, downregulated Vimentin and survivn level in glioma cells as well as inhibited ROS generation and increased SOD activity. In conclusion, the level of miR-34a-5a in glioma cells is up-regulated by APS so as to restrain the biological behaviors of glioma cells, indicating that it might be used as novel agent for the treatment of glioma.
