Triterpenoids from the Leaves of Centella asiatica Inhibit Ionizing Radiation-Induced Migration and Invasion of Human Lung Cancer Cells

Figure 5

Effects of compounds 1–3 on the IR-induced invasion of A549 cells: (a) cell invasion was assessed using Matrigel-coated transwell plates in nonirradiated and γ-irradiated A549 cells treated with 2.5 and 5 μM compounds 1–3, respectively; (b) quantification of invasion. The percentage of invasion is represented as the number of cells per field compared with each nonirradiated A549 cell group. Data represent the mean ± SD (n = 3); ; versus the control.
