DMEΔ inhibits cell proliferation and causes DNA damage in HEK-293T cells. (a) Cell proliferation rates of the 293T-GFP, 293T-DMEΔ and 293T-DMEΔ(K1286Q) cells after transfection. DMEΔ(K1286Q) is a catalytically inactive fragment and was used as a negative control19. (b) Cell proliferation rates of the 293T-GFP and 293T-DMEΔ cells in the presence or absence of 25 μM 5aza in the culture medium. (c) Fractions of TUNEL-positive cells were analysed by flow cytometry. (d) TUNEL assays in the 293T-GFP and 293T-DMEΔ cells 48 h after transfection. Scale bar = 10 μm. (e) PI staining of the 293T-GFP and 293T-DMEΔ cells 48 h after transfection. Scale bar = 20 μm. Error bars represent mean ± S.D. of three independent experiments. *p < 0.05; paired sample t-test.
