BREAST CANCER RES:通过多种Omic方法分析乳腺癌细胞系的特征

2017-06-15 MedSci MedSci原创

乳腺癌细胞系经常被用作模型系统来研究乳腺癌的细胞特性和生物学。我们的目标是表征从美国典型培养物保藏中心(ATCC 30-4500 K)获得的一个大型常用的乳腺癌细胞系,使研究人员能够在选择细胞系进行特定研究时作出更明智的决定。首先,从各种来源获得关于这些细胞系的信息。 此外,生成了在每个细胞系内被激活的关于细胞途径的新信息。

背景:乳腺癌细胞系经常被用作模型系统来研究乳腺癌的细胞特性和生物学。我们的目标是表征从美国典型培养物保藏中心(ATCC 30-4500 K)获得的一个大型常用的乳腺癌细胞系,使研究人员能够在选择细胞系进行特定研究时作出更明智的决定。首先,从各种来源获得关于这些细胞系的信息。此外,生成了在每个细胞系内被激活的关于细胞途径的新信息。

方法:我们使用免疫印迹分析确定了关键的蛋白质表达数据。 此外,进行了关于血清饥饿细胞的两项分析以鉴定在这些细胞中被激活的细胞蛋白质和信号通路。这些分析使用商业的PathScan阵列和一种新颖且更广泛的基于磷酸肽的kinome分析来进行,该分析可以查询主要信号通路中的1290个磷酸化事件。关于这一组乳腺癌细胞系的数据也从几个在线来源获取,汇编和总结了以下领域:分子分类,mRNA表达,关键蛋白的突变状态和其他可能的癌症相关突变,以及在乳腺癌的小鼠异种移植模型中致瘤和转移能力。

结果:除4种非致瘤性乳腺细胞系外,我们表征的细胞系包括10个雌激素受体(ER)阳性,12个人表皮生长因子受体2(HER2)倍增和18个三阴性乳腺癌细胞系。在每个亚型中,存在显着的遗传异质性,可以影响模型细胞系的选择和所得结果的解释。这为哪些细胞系以常见或独特的方式进行调节,提供了进一步的清晰的了解。
