Figure 5From: The long non-coding RNA, GAS5, enhances gefitinib-induced cell death in innate EGFR tyrosine kinase inhibitor-resistant lung adenocarcinoma cells with wide-type EGFR via downregulation of the IGF-1R expressionFlow-cytometric analysis was used to determine the percentage of apoptotic cells. (A) Representative flow-cytometric analysis results of four groups. (B) A549 cell treated with gefitinib plus GAS5 showed decreased apoptosis. The data represent the mean ± SD from three independent experiments. **P < 0.01Back to article page
