Related to testes-specific, vespid and pathogenesis protein-1 (RTVP-1), also known as glioma pathogenesis-related protein 1, is highly expressed and has oncogenic features in glioblastoma (GBM; World Health Organization class IV). Promoter methylation has been found to control RTVP-1 expression in prostate carcinoma, Wilms' tumor, acute myeloid leukemia and melanoma. In this bi-institutional study, the methylation status of RTVP-1 in astrocytic brain malignancies (GBM and oligodendroglioma) was examined. The RTVP-1 promoter was hypomethylated in GBM compared with non-tumor brain samples, but was hypermethylated in oligodendroglioma. RTVP-1 methylation correlated with RTVP-1 expression at the mRNA level. In GBM, hypermethylation of the RTVP-1 promoter was associated with improved overall survival although with no statistical significance.
睾丸特异性黄蜂毒液和致病相关蛋白-1(RTVP-1),也被称为胶质瘤致病相关蛋白1,在胶质母细胞瘤(GBM;世界卫生组织IV级)中高表达且具有致癌特性。已发现启动子甲基化可控制前列腺癌、肾母细胞瘤、急性髓系白血病和黑色素瘤中RTVP-1的表达。在这项双机构研究中,检测了星形细胞脑恶性肿瘤(GBM和少突胶质细胞瘤)中RTVP-1的甲基化状态。与非肿瘤脑样本相比,GBM中RTVP-1启动子呈低甲基化,但在少突胶质细胞瘤中呈高甲基化。RTVP-1甲基化与mRNA水平的RTVP-1表达相关。在GBM中,RTVP-1启动子的高甲基化与总体生存率的改善相关,尽管无统计学意义。
