Fig. 3From: Relationship between long non-coding RNA PCAT-1 expression and gefitinib resistance in non-small-cell lung cancer cellsPCAT-1 knockdown enhanced gefitinib-induced apoptosis in H1299/GR cells. a, b Flow cytometric analysis was performed to detect the percentage of apoptotic cells. c PCAT-1 Knockdown enhanced cleaved Caspase 3 expression, as measured by immunofluorescence. The cell cycle distribution of H1299/GR cells were analyzed using flow cytometry after transfection. *, p < 0.05, **, p < 0.01Back to article page
