DNA甲基化异常,特别是启动子高甲基化和肿瘤抑制基因的转录沉默,在包括肾细胞癌(RCC)在内的许多人类癌症的发生发展中起着重要作用。事实上,除了研究得很好的von Hippel-Lindau基因(VHL)突变外,已知的肿瘤抑制基因在肾癌中的突变率通常很低,但在肾癌中发现的因启动子甲基化而频繁失活的基因数量继续增加。在这里,我们回顾了在肾癌中被鉴定为表观遗传沉默的基因及其与肿瘤发展途径的关系。对肾癌表观遗传学的深入了解为肾癌的分子发病机制提供了新的见解,并为肾癌的诊断、预后和治疗提供了新的策略。
Aberrant DNA methylation, in particular promoter hypermethylation and transcriptional silencing of tumor suppressor genes, has an important role in the development of many human cancers, including renal cell carcinoma (RCC). Indeed, apart from mutations in the well studied von Hippel-Lindau gene (VHL), the mutation frequency rates of known tumor suppressor genes in RCC are generally low, but the number of genes found to show frequent inactivation by promoter methylation in RCC continues to grow. Here, we review the genes identified as epigenetically silenced in RCC and their relationship to pathways of tumor development. Increased understanding of RCC epigenetics provides new insights into the molecular pathogenesis of RCC and opportunities for developing novel strategies for the diagnosis, prognosis and management of RCC.
