Abstract

Stimulation of vascular endothelial cells by tumor necrosis factor alpha (TNFalpha) plays a critical role in the pathogenesis of inflammation and vascular diseases. Changes in the gene expression profile in cultured human umbilical vein endothelial cells (HUVEC) treated with TNFalpha was analyzed with high-density oligonucleotide arrays comprised of 35,000 genes. TNFalpha stimulation profoundly induced genes involved in signal transduction, leukocyte adhesion and chemoattraction. ICAM-1 mRNA (fold change 111.9) was most profoundly induced followed by TNFalpha receptor-associated factor 1 (TRAF1) (95.5), Bcl3 (71.8), IL8 (65.4), fractalkaine (62.4), E-selectin (48.0), lymphotoxin beta (41.3) and VCAM-1 (31.7). In addition to these previously known genes, 18 poorly characterized or novel genes known as ESTs profoundly induced by TNFalpha. Initial sequencing analysis identified three of these the genes for squalene epoxydase, chromodomain helicase DNA binding protein 4, and CLP respectively. Further analysis of these genes will provide important information about TNFalpha signaling and function in vascular endothelial cells.
