Fig. 4From: Lotus leaf flavonoids induce apoptosis of human lung cancer A549 cells through the ROS/p38 MAPK pathwayEffect of lotus leaves flavonoids (LLF) on ROS content in A549 lung cancer cell. Control: untreated A549 cells. Compared with the control group, the difference was significant (*p < 0.05; **p < 0.01). Control: untreated A549 cells. Cells were treated with LLF at 125, 250 and 500 µg/mL for 48 h (n = 6)Back to article page
