AbstractWe have examined the possible role of transforming growth factor-β (TGF-β) in metastatic malignancy by analyzing the production and activation of TGF-β, and -β2 and the regulation of TGF-β-responsive genes in oncogene-transformed metastatic fibrosarcomas. All transformed lines derived from either 10T1/2; or N1H 3T3 bv either H-ras or protein-kinase encoding oncogenes produced more TGF-β than parental cells. However, onlv highlv metastatic fibrosarcomas secreted activated TGF-β at rates that were greater than parental fibroblasts. Immunohistochemical staining for TGF-β, showed widespread intra- and extracellular distribution in metastatic lung nodules and adjacent tissue. Cells isolated from tumors successfully metastasizing to the lung had TGF-β1, mRNA levels which were increased 19-fold over in ritro controls. Despite the greatly enhanced rate of secretion of activated TGF-β, metastatic cells exhibited markedly altered responses of TGF-β1, and TGF-β2., being unable to either increase collagen sec...
