| Research Abstract |
1) Transfection of siRNA for VEGF-A to U87 and U251 glioma cells decreased their VEGF-A expression.
2) Tube formation of HUVECs on fibrin gel was observed in culture media(CM) from U87 and U251 glioma cells, but not in CM from glioma cells transfected by siRNA for VEGF-A.
3) siRNA for VEGF-A by magentofection could be transfected into cultured glioma cells faster than by conventional methods.
4) Expression of VEGF-A was higher in malignant gliomas compared to low-grade gliomas.
5) Expression of HuR was higher in malignant gliomas compared to low-grade gliomas.
6) Transfection of siRNA for HuR to U87 and U251 glioma cells decreased their proliferation as well as VEGF-A expression.
7) Leptomycin B, which is one of HuR inhibitor, decreased the proliferation and VEGF-A expression in U87 and U251 glioma cells.
8) Magnetofection of siRNA for VEGF-A impregnated in atherocollagen did not inhibit the growth of the implanted U87 glioma under the skin of nude mice.
