Recombinant human tissue inhibitors of metalloproteinases (rhTIMP-2) have been shown to suppress tumor growth and tumor-associated angiogenesis. NCI Radiation Oncology Branch (ROB) researchers have developed a unique HEK-293F cell line which stably expresses rhTIMP-2, increasing the production of TIMP-2 to quantities sufficient to be used for testing and development as a therapeutic for various cancers, ischemic diseases (myocardial infarct and cerebrovascular infarct), and neurodegenerative diseases.
