The delayed TGFβ-mediated entry of Smad3 into the nucleus in the presence of SB-203580 prompted us to examine the effect of SB-203580 on TGFβ-induced gene expression in a time-course experiment.
Evidence has been accumulated that TGFβ promotes late-stage tumorigenesis by stimulating angiogenesis and invasive behaviour of tumor cells, enhancing immunosuppression and supporting epithelial-mesenchymal transition of cancer cells [ 4 ] . Furthermore, TGFβ is believed to be part of a vicious circle in bone metastases as it gets released from osteoclast-degraded bone substance and subsequently stimulates PTHrP gene expression in nearby metastatic cancer cells which in turn leads to an activation of osteoclastic bone resorption [ 11 ] . Therefore, it is of great interest to understand in more detail the molecular aspects of TGFβ-mediated gene expression in metastatic breast cancer cells and to explore ways to interfere with this tumorigenic signalling.
Malignant tumor cells frequently show deregulation and hyperactivation of signalling pathways, one of which is represented by the TGFβ signal transduction pathway [ 1 ] . TGFβ has been shown to potently inhibit proliferation of most epithelial, endothelial and hematopoietic cells [ 2 ] . However, during tumor progression malignant cells may become refractory to TGFβ-mediated cell cycle arrest.
TGFβ induced pai-1 mRNA was reduced to approximately 50% by the SB inhibitor, whereas TGFβ-mediated expression of PTHrP and uPA was highly sensitive to SB-203580 treatment.
Here we report that two small molecules, SB-202190 and SB-203580, diminished TGFβ-induced expression of TGFβ target genes which was accompanied by a perturbation of TGFβ-mediated Smad3 nuclear accumulation, a crucial step in TGFβ signal transduction.
