SB-202190 and SB-203580 deregulate TGFβ-induced Smad3 nuclear accumulation
Alternatively, inhibitory Smad7, whose expression was increased by TGFβ but not affected by SB-203580, may be involved in this process.
TGFβ has been shown also to stabilize the mRNA of the smad7 gene [ 25 ] , while stabilization of RNA does not play a major role in regulation of the pthrp gene in MDA-MB-231 cells [ 19 ] . In addition, SB-203580 also inhibits p38 activity which has been shown to play a role in TGFβ signalling [ 36 37 38 39 40 41 ] . Hence, several factors could be responsible for the differential sensitivity of TGFβ-responsive genes to SB-203580.
However, pretreatment of the cells with 20 μM SB-203580 perturbed Smad3 nuclear accumulation, reducing the amount of Smad3 entering the nucleus and shifting the peak level of nuclear Smad3 to a later time point.
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.
