title: Transforming growth factor-beta 1 is a potent inducer of plasminogen activator inhibitor type-1 in human glioblastoma and carcinoma cell lines.
abstract: Transforming growth factor-beta 1 has been shown to suppress the urokinase activity in the glioblastoma cell line T-MG1 and the carcinoma cell line T-CAR1. The molecular mechanisms behind the decrease in the proteolyic activity is shown to be at least partly due to increased synthesis of plasminogen activator inhibitor type-1 and not by decreased synthesis of urokinase.
