中文摘要
将EML4-ALK阳性的肺癌细胞(H2228细胞株)培养在含有碱性磷酸酶抑制剂(Crizotinib)的培养液中,建立耐药细胞。第二,在这些细胞中没有检测到ALK激酶编码区的突变。通过实时定量RT-PCR分析,在耐药细胞中发现了四个长的非编码RNA的表达变化。对这些变化的功能分析正在进行中。
英文摘要
EML4-ALK positive lung cancer cells (H2228 cell line) were cultured in medium containing an ALK kinase inhibitor (Crizotinib), and crizotinib-resistant cells were established. Second mutations within the ALK kinase-codingregion were not detected in those cells. Altered expression of four long non-coding RNAswere identified by real-time quantitative RT-PCR analyses in the resistant cells. Functional analyses of the alterations are in progress.
