We have found that T beta 4 upregulates the expression of plasminogen activator inhibitor 1 (PAI-1) in endothelial cells measured both at the level of mRNA and protein synthesis. This effect seems to be cell specific and was not observed when other cells such as human fibroblasts, PC3, and U937 were tested. T beta 4 significantly activated the PAI-1 promoter in EA.hy 926 cells transiently transfected either with plasmid p800LUC containing PAI-1 promoter fragment (-800 to +71) or the PAI-1 promoter linked with green fluorescent protein. T beta 4 mediated up-regulation of PAI-1 involved activation of the mitogen-activated protein kinase cascade. Furthermore, T beta 4 enhanced c-Fos/c-Jun DNA-binding activity to the activator protein 1 (AP-1)-like element (-59 to -52). The specificity of this binding activity was demonstrated by competition electrophoretic mobility shift assay and after transfection of EA.hy 926 cells with the mutated PAI-1 promoter. Taken together, these data indicate that, in response to T beta 4 stimulation, AP-1 activity increases to enhance PAI-1 transcription through its unique AP-1-like element at -59 to -52 in the PAI-1 promoter."xsd:string |
