    摘要: Mutants of the human PAI-1 protein are described which are inhibitors of neutrophil elastase or are inhibitors of vitronectin (Vn)-dependent cell migration. These mutants preferably comprise one or two amino acid substitutions in the reactive center loop of PAI-1, particularly at positions 331 and 346 of the mature protein. These mutants are notable in being resistant to inactivation by elastase, having high affinity for Vn, or both properties. These mutant proteins as pharmaceutical compositions are used to inhibit elastase in a subject, thereby treating a number of disorders associated with elastase activity, most notatably emphysema, ARDS, inflammatory lung injury and cystic fibrosis. The mutants which interact with Vn are used to inhibit cell migration in a subject, thereby treating diseases or conditions associated with undesired cell migration and proliferation, particularly of smooth muscle cells. Such conditions include atherosclerosis, post angioplasty restenosis, fibrosis associated with chronic inflammation or chemotherapy, tumor invasion and metastasis and conditions in which angiogenesis is pathogenic. Also disclosed are peptides of such mutant proteins, mutant-specific antibodies, nucleic acid molecules, particularly DNA, encoding the mutant protein and host cells transformed by such nucleic acids.

    摘要: a monoclonal antibody which binds a human endothelial type plasminogen activator inhibitor (PAI-1) produced by dexamethasone-treated human HT-1080 fibrosarcoma cells may be used, inter alia, for determining PAI-1 protein abundance in tumor tissue or a sample of a body fluid. Measurements of this parameter may be useful in predicting the presence or metastasis of a tumor, or of predicting the progression of a known malignant tumor.
