Bone morphogenetic protein-2 suppresses invasiveness of TSU-Pr1 cells with the inhibition of MMP-9 secretion.
Bone morphogenetic protein (BMP), which is a member of the transforming growth factor beta (TGF-beta) superfamily, has powerful osteoinductive effects and various biological activities in a variety of cells. The effect of BMP-2 on the human carcinoma cell line TSU-Pr1 was examined. BMP-2 was found to inhibit the migration and invasiveness, but not the proliferation, of TSU-Pr1 cells. Gel zymography for matrix metalloproteinases (MMPs) and urokinase-type plasminogen activator (uPA) detection revealed that BMP-2 down-regulated the activity of MMP-9, but not of MMP-2 or uPA. BMP-2 also reduced the secretion of MMP-9 into the culture media, but did not affect the secretion of MMP-2, Timp-1, Timp-2 or Timp-3. These results suggest that BMP-2 inhibits migration and decreases MMP-9 secretion to suppress the invasiveness of TSU-Pr1 cells. This is the first report of a role for BMP signaling in reducing the invasiveness of cancer cells.
