我们最近报道了DAB2IP在肾癌发展中的肿瘤抑制作用。在这项研究中,我们从癌症基因组图谱(TCGA)中发现了一个位于DAB2IP UTS的CpG甲基化生物标记物(DAB2IP CpG1),它与总体生存率较低有关。我们通过焦磷酸测序定量甲基化分析进一步验证了来自多个中国中心(MCHC SET)的224例ccRCC患者(MCHC SET)和来自德克萨斯大学达拉斯西南医学中心(UTSW SET)的239例CpG甲基化患者(FFPE样本)DAB2IP CpG甲基化预测预后的准确性。DAB2IP CpG1可以独立于患者的年龄、Fuhrman分级和TNM分期来预测TCGA、MCHC和UTSW组患者的总体生存时间(均P<0.05)。DAB2IP CpG1成功地将患者分为高风险组和低风险组,在各自的临床亚组中,无论年龄、性别、级别、阶段或种族,临床结果都有显著差异(HR:1.63-7.83;均P<0.05)。肾细胞癌组织中DAB2IP CpG1甲基化的检测受ITH影响最小。DAB2IP基因在体外的表达受DNA甲基化的调节。DAB2IP CpG1甲基化是一种实用的、可重复的ccRCC生物标志物,可以提供预后价值,补充目前的分期系统。
We have recently reported tumor suppressive role of DAB2IP in RCC development. In this study, We identified one CpG methylation biomarker (DAB2IP CpG1) located UTSS of DAB2IP that was associated with poor overall survival in a cohort of 318 ccRCC patients from the Cancer Genome Atlas (TCGA). We further validated the prognostic accuracy of DAB2IP CpG methylation by pyrosequencing quantitative methylation assay in 224 ccRCC patients from multiple Chinese centers (MCHC set), and 239 patients from University of Texas Southwestern Medical Center at Dallas (UTSW set) by using FFPE samples. DAB2IP CpG1 can predict the overall survival of patients in TCGA, MCHC, and UTSW sets independent of patient age, Fuhrman grade and TNM stage (all p<0.05). DAB2IP CpG1 successfully categorized patients into high-risk and low-risk groups with significant differences of clinical outcome in respective clinical subsets, regardless of age, sex, grade, stage, or race (HR: 1.63-7.83; all p<0.05). The detection of DAB2IP CpG1 methylation was minimally affected by ITH in ccRCC. DAB2IP mRNA expression was regulated by DNA methylation in vitro. DAB2IP CpG1 methylation is a practical and repeatable biomarker for ccRCC, which can provide prognostic value that complements the current staging system.
