Protective effect of atorvastatin on radiation-induced endothelial cell injury

Abstract

Objective: To explore the protective effect of atorvastatin on irradiated endothelium and the thrombomodulin (TM) expression. Methods: Cultured human coronary artery endothelial cells (HCAEC) and human umbilical vein endothelial cells (HUVEC) were treated by atorvastatin at the final concentration of 10 {mu}mol/ml for 10 min, and then irradiated with 2 and 25 Gy. Cell cycles status and TM expression were quantitatively measured by flow cytometry 24 hours after irradiation. Protein C activation in endothelial cells was also assessod. Results: After administration with atorvastatin for 24 h, the TM expression increased by 77%, 59% and 61% in normal control group, 2 Gy group and 25 Gy group, respectively (t=27.395, 26.420, 58.065; P=0.000). The protein C levels decreased by 23% and 34% compared with the normal group post-irradiation to 2 and 25 Gy, but increased by 79% and 76% compared with the irradiated control group after administration with atorvastatin. The rates of cell apoptosis decreased by 6% and 16% in 2 Gy and 25 Gy groups, respectively after administration with atorvastatin for 24 h (t=4.178, 17.863; P=0.000). Conclusions: Atorva statin can protect endothelia cell from irradiation-induced apeptosis by increasing TM expression and protein C activation. (authors)
