The transforming growth factor β1 (TGF-β1) belongs to a family of structurally related polypeptide factors. TGF-beta plays an important role in the pathobiology of invasion of malignant gliomas. The objective of the present study was to investigate the impact of TNF-α converting enzyme (TACE/ADAM17) signaling on the process of TGF-β1-stimulated migration and invasion of T98G glioma cells. We found that TGF-β1 increased migration and invasiveness in glioma cells. Addition of the TGF-β1 receptor inhibitor, SB431542, reduced the TGF-β1-stimulated migration and invasiveness of glioma cells. In addition, TGF-β1-induced migration and invasiveness were also blocked by exposure to an ADAM17 inhibitor, TAPI-2. Furthermore, ADAM17 mRNA and protein expression were up-regulated by TGF-β1. Treatment with SB431542 and TAPI-2 blocked TGF-β1-induced ADAM17 protein expression. In summary, these results indicate that TGF-β1 promotes cell migration and invasiveness of glioma cells through stimulation of ADAM17.
