Nat Genet:识别癌症驱动因子的新方法

2014-08-28 佚名 生物谷

近日,一组研究人员开发出一种能查明癌症的基因“驱动程序”的新综合方法,新研究揭示了可能是治疗乳腺癌的八个可行靶标基因。 这项研究发表在Nature Genetics杂志上。研究人员研究了多种致癌途径,涉及正常细胞转变成癌细胞过程中的基因变异,其中包括控制癌细胞生长率的基因途径。细胞的高生长速率也被称为细胞增殖,被认为与乳癌患者不良预后有关。 分析多种类型基因组数据,研究人员能够确定在基因组

近日,一组研究人员开发出一种能查明癌症的基因“驱动程序”的新综合方法,新研究揭示了可能是治疗乳腺癌的八个可行靶标基因。

这项研究发表在Nature Genetics杂志上。研究人员研究了多种致癌途径,涉及正常细胞转变成癌细胞过程中的基因变异,其中包括控制癌细胞生长率的基因途径。细胞的高生长速率也被称为细胞增殖,被认为与乳癌患者不良预后有关。

分析多种类型基因组数据,研究人员能够确定在基因组DNA水平扩增的8个基因,这8个基因对于管腔乳腺癌细胞增殖所必需的。

使用这种新的计算方法,我们能够利用现有丰富数据资源,确定针对乳腺癌患者特定子集的若干新的潜在药物靶标。

事实上,所鉴定出的8个基因中的基因CPT1A已经是淋巴瘤药物治疗靶标,并很有可能被用于乳腺癌患者治疗。靶向CPT1A药物在体外、淋巴瘤的小鼠模型中已被证明能抑制人类肿瘤细胞系生长。

利用多种数据类型的全面和综合分析,包括基因表达数据,体细胞突变,DNA拷贝数以及功能基因组学数据集,能更好地了解癌症的驱动基因。
