This study was purposed to characterize the effect of carboxylic acid metabolite (SR26334) of clopidogrel bisulfate deprived of antiplatelet efficacy on the spectrum of gene expression in the cultured human umbilical vein endothelial cell (HUVEC) line (EA.hy926), and to explore the potential molecule mechanism of SR26334 impact on HUVEC. By using a Affymetrix HU133 plus 2.0 oligonucleotide microarray, the alteration of gene expression spectrum induced by SR26334 in HUVEC was detected, the real-time PCR was used to confirm the results of selected differentially expressing genes. The results indicated that total 235 including 176 up-regulated and 59 down-regulated genes were obtained with change more than 1.5-fold after SR26334 (10 ┬Ámol/L) acted on HUVEC for 48 h. SR26334 affected the expression levels of genes involved regulation of transcription, transcription, positive regulation of transcription from RNA polymerase II promoter, cell cycle, cell division, protein amino acid dephosphorylation in HUVEC. It is concluded that carboxylic acid metabolite SR26334 of clopidogrel bisulfate modulates function of endothelial cells through different pathway at gene level.
