Impact of clopidogrel on gene profile of human umbilical vein endothelial cell line and bioinformatics analysis / 中国实验血液学杂志

ABSTRACT

This study was purposed to investigate the effect of clopidogrel on gene expression profile of cultured human umbilical vein endothelial cell (HUVEC) line (EA.hy926), and explore its potential molecule mechanism. A Affymetrix U133 plus 2.0 oligonucleotide microarray was applied to detect the alteration of gene expression profile induced by clopidogrel in HUVEC. Real time RT-PCR was used to verify the result of selected differentially expressing genes. The results showed that total 508 genes (including 139 up-regulated and 369 down-regulated genes) were obtained with differential expression more than 1.5-fold after clopidogrel (10 µmol/L) acted on HUVEC for 48 h. Clopidogrel affected the expression levels of genes involved protein binding, transcription factor activity, zinc ion binding, regulation of DNA-dependent transcription, transcription, RNA splicing and so on. It is concluded that the clopidogrel modulate function of endothelial cells by regulating sets of genes through different pathway.
