We found that the glioma tissue was positive for A2B5 (Glial precursors ganglioside), GFAP (Glial fibrillary acidic protein), S-100 (Acid calcium bingding protein), VEGF (Vascular endothelial growth factor), VEGFR (Vascular endothelial growth factor receptor) and negative for Ki-67 (Nuclcar- associated antigen). The gene discussed is GFAP; the disease is central nervous system cancer.
