LPS response of cardiovascular endothelial cells transduced with an APEX1(1-20) expressing vector or an empty vector
Sepsis is an exaggerated immune response upon infection with lipopolysaccharide (LPS) as the main causative agent. LPS-induced activation and apoptosis of endothelial cells (EC) can lead  to organ dysfunction and finally organ failure. We have previously demonstrated that the first twenty amino acids of the Apurinic/Apyrimidinic Endodeoxyribonuclease 1 (APEX1) are sufficient  to inhibit EC apoptosis. To identify genes whose regulation by LPS is affected by this N-terminal  APEX1 peptide, EC were transduced with an expression vector for the APEX1 peptide or an empty control vector and treated with LPS. Following RNA deep sequencing, genes upregulated in LPS-treated EC expressing the APEX1 peptide were identified bioinformatically.
