胶质瘤的发生是由于染色体及基因异常所致，对癌基因ｃ－ｍｙｃ、Ｈｒａｓ及抑癌基因Ｐ５３的检测，发现Ｈｒａｓ与胶质瘤的发生有关，而胶质瘤的恶性程度与ｃ－ｍｙｃ癌基因的扩增及抑癌基因Ｐ５３的突变有关。材料和方法２２例肿瘤标本均为手术切除的新鲜瘤组织，经...
The occurrence of gliomas is due to chromosome and gene abnormalities. The detection of oncogenes c-myc, H-ras, and tumor suppressor gene P53 revealed that H-ras is associated with the occurrence of gliomas, and the malignant of gliomas. The degree is related to the amplification of c-myc oncogene and the mutation of tumor suppressor gene P53. Materials and Methods Twenty-two tumor specimens were freshly resected tumor tissue.
