Role of HCMV infection in the activation and oxidative stress of cultured human umbilical vein endothelial cells / 中华实验和临床病毒学杂志

ABSTRACT

Objective@#To investigate the role of the activation and oxidative stress of cultured human umbilical vein endothelial cells (HUVEC) after HCMV infection.@*Methods@#HUVECs were divided into four groups: control, HCMV(+ ), after HCMV AD169 infection, and the supernatant of the culture was extracted, and the cells were lysed. The levels of vascular cellular adhesion molecule-1 (VCAM-1) in HUVEC were measured by real-time PCR. And the content of nitrogen monoxide (NO) of the supernatant was detected by nitrate reductasemethod accordingly.@*Results@#Twenty-four hours after infection, the mRNA expression of VCAM-1 in HUVECs of HCMV infected group increased obviously compared to control, and NO quantity increased accordingly and time-dependently. There was significant difference between groups(P<0.01).@*Conclusions@#HCMV increases the mRNA expression of VCAM-1 and quantity of NO, which may contribute to the formation of AS.
