Effect of LbGp on DEHP caused apoptosis in HEK-293 cells and HK-2 cells. The percentage of apoptotic cells treated with DEHP and LbGp at 24 h (A and B), 48 h (C and D), and 72 h (E and F) was determined by flow cytometry. ^#P < 0.05, ^##P < 0.01, ^###P < 0.001, and ^####P < 0.0001 in comparison with the control group. ^*P < 0.05, ^**P < 0.01, ^***P < 0.001, and ^****P < 0.0001 in comparison with the DEHP group. HEK-293, human embryonic kidney-293 cells; HK-2, human kidney-2 cells; DEHP, di(2-ethylhexyl) phthalate; LbGp, Lycium barbarum glycopeptide; ConA, concanavalin A; L, low-dose (300 µg/ml); M, middle-dose (750 µg/ml); H, high-dose (1500 µg/ml); PI, propidium iodide
