Fast TGFβ responder genes, such as smad7 , whose maximum activation by TGFβ was reached after 60 min, was only slightly affected by SB-203580, while slow responders, such as pai-1, pthrp or upa , that showed peak activation after 180-240 min, were very sensitive to the repressive effect of SB-203580.
We have previously demonstrated that TGFβ upregulates PTHrP and PAI-1 RNA levels in MDA-MB-231 cells [ 19 ] . TGFβ affected PTHrP expression primarily by increasing the level of the promoter P3-specific transcript [ 19 ] . Quantitative PCR analysis using primers allowing the detection of PTHrP P3 and PAI-1 transcripts indicated that incubation of MDA-MB-231 cells with SB-202190 and SB-203580 greatly inhibited TGFβ-induced increase in PTHrP and, to a lesser extent, PAI-1 mRNA levels (Fig.
We demonstrate that treatment of invasive MDA-MB-231 breast cancer cells with SB-202190 and SB-203580 interferes with TGFβ-induced Smad3 nuclear accumulation and that this is paralleled by a differential transcriptional response of TGFβ target genes.
Using SB-203580, we found that not only was the total level of nuclear Smad3 in the presence of TGFβ reduced, but also that the nuclear entry of Smad3 was delayed and less prolonged.
SB-202190 and SB-203580 deregulate TGFβ-induced Smad3 nuclear accumulation
