Transcription profiling of human umbilical vein endothelial cells (HUVEC) treated with thrombin and leukotriene D4 (LTD4) with ethanol controls to delinate Cysteinyl leukotrienes mode of action

ABSTRACT: Cysteinyl leukotrienes (cysLT), i.e. LTC4, LTD4, and LTE4, are lipid mediators derived from the 5-lipoxygenase pathway. The cysLT receptors cysLT1-R and cysLT2-R are expressed on different target cells and mediate inflammatory reactions in tissue- and LT-R-specific ways. Though endothelial cells (ECs) predominantly express cysLT2-Rs, their role in vascular biology remains to be defined. To delineate cysLT2-R´s action, we stimulated human umbilical vein EC with 100 nM LTD4 for 60 min, determined gene signatures by microarrays, and characterized the resulting EC phenotypes. As controls, we compared LTD4-induced genes with those induced by 10 nM thrombin, a prototype vasoactive activator of EC that binds to protease-activated receptor 1 (PAR-1).
