Effect of G4-stabilizing compound TMPyP4 on 8-oxoG incorporation into VEGF G4 and HRE sequences. Pre-treating PAECs with TMPyP4 prior to exposure to hypoxia for 3 hours protected the VEGF G4 (A) but not the VEGF HRE (B) from oxidation of guanine to 8-oxoG. *Significantly different from vehicle control (P<0.05).
