ROS affect the NgBR levels in PAECs. (A) H₂O₂ at 40 μM final concentration applied every 8 hours for 24 and 48 hours decreased the NgBR protein levels in control PAECs. (B) N-acetylcysteine (NAC) at 500 μM final concentration applied once every 24 hours for 2 days increased NgBR levels in IPH PAECs. Open bar, no treatment; closed bar, corresponding H₂O₂ or NAC treatment. *P < 0.05 compared with no treatment; ^#P < 0.05 compared with 48 hours; ^†P < 0.05 compared with 24 hours. Data are shown as mean (± SE).
