癌症被列为所有人类疾病的头号杀手之一,并继续对全球人口产生毁灭性影响。目前的研究工作旨在加速我们对癌症分子基础的理解,并开发癌症诊断、治疗和预后的有效手段。表观遗传修饰模式的改变,最重要的是 DNA 甲基化事件,通过调节癌基因激活、抑癌基因沉默和染色体不稳定,在肿瘤发生中发挥着关键作用。为了研究 DNA 甲基化、基因表达和癌症之间的相互作用,我们开发了一个可公开访问的人类 DNA 甲基化和癌症数据库(MethyCancer,http://methycancer.genomics.org.cn)。 MethyCancer 既拥有来自公共资源的 DNA 甲基化、癌症相关基因、突变和癌症信息的高度集成数据,也拥有来自我们大规模测序的 CpG 岛 (CGI) 克隆。分析并呈现了不同数据类型之间的互连。此外,还开发了功能强大的搜索工具,以提供对所有数据和数据连接的用户友好访问。图形 MethyView 显示基因组学和遗传学数据背景下的 DNA 甲基化,促进癌症研究,了解使肿瘤细胞基因表达发生巨大变化的遗传和表观遗传机制。
Cancer is ranked as one of the top killers in all human diseases and continues to have a devastating effect on the population around the globe. Current research efforts are aiming to accelerate our understanding of the molecular basis of cancer and develop effective means for cancer diagnostics, treatment and prognosis. An altered pattern of epigenetic modifications, most importantly DNA methylation events, plays a critical role in tumorigenesis through regulating oncogene activation, tumor suppressor gene silencing and chromosomal instability. To study interplay of DNA methylation, gene expression and cancer, we developed a publicly accessible database for human DNA Methylation and Cancer (MethyCancer, http://methycancer.genomics.org.cn). MethyCancer hosts both highly integrated data of DNA methylation, cancer-related gene, mutation and cancer information from public resources, and the CpG Island (CGI) clones derived from our large-scale sequencing. Interconnections between different data types were analyzed and presented. Furthermore, a powerful search tool is developed to provide user-friendly access to all the data and data connections. A graphical MethyView shows DNA methylation in context of genomics and genetics data facilitating the research in cancer to understand genetic and epigenetic mechanisms that make dramatic changes in gene expression of tumor cells.
