Knockdown of TF with TF-siRNA induced apoptosis of lung adenocarcinoma cells. The transfected cells, labeled with AnnexinV-FITC and propidium iodide, were subjected to flow cytometric analysis. Two parameter histogram Dot Plot displayed FL1-FITC on the x axis and FL2-PI on the y axis. The result showed that TF-siRNA increased the apoptotic rate in A549 cells in a dose-dependent manner.
