Protective effect of ATX on H ₂ O ₂ -induced cell death. (A) HTECs were incubated with different concentrations of H₂O₂ for 2 h. (B) HTECs were incubated with different concentrations of ATX for 24 h. (C) HTECs were pretreated with ATX (250 nM) for 24 h and then exposed to H₂O₂ (100 μM) for 2 h. *, P < 0.01 compared with control group, #, P < 0.01 compared with H₂O₂ group.
