Representation of the 507 hypoxia regulated genes that were able to be analyzed for the presence of a potential promoter G4 sequence. White indicates genes that were found by microarray to be up-regulated in PAECs after 3 hours of hypoxia (258 genes or 51%). Gray represents those genes that were down-regulated (249 genes or 49%). The portion with lines represents those genes predicted to have a G4 within the promoter (123 total genes or 24%). The genes up-regulated in hypoxia were more likely to have a promoter G4 (75 or 61% of G4s).
