ABSTRACT
Objective To explore protective effect of Heme oxygenase-1(HO-1) on irradiation-induced endothelial cell apoptosis.Methods Human endothelial cell line EA.hy926 were administered with or without HO-1 activator Copp and/or HO-1 inhibitor Znpp,respectively.Then,cells were treated with or without 8 Gy radiation.The HO-1 protein expression of cells were assessed with Western blotting and apoptosis of cells treated with irradiation were evaluated with flow cytometry.Moreover,cytochrome C releasing into cytosol were also determined by Western blotting. Results In PBS+R group,HO-1 protein expression of EA.hy926 was low posterior to irradiation.When cells were preconditioned with Copp and/or Znpp,then recieved with 8Gy irradiation,the HO-1 protein expression of EA.hy926 increased significantly in comparision with the PBS+R group(P
