However, TGFβ downregulated Ese-1/Esx mRNA levels faster than it upregulated Smad7 expression excluding the possibility that Smad7 mediates the TGFβ effect on Ese-1/Esx, at least at the initial phase.
One way by which Smad7 can inhibit TGFβ-dependent gene expression is by blocking phosphorylation, and, hence, nuclear import of Smad3 and Smad2 [ 23 ] . More recent data showing that Smad7 is able to interact with histone deacetylases suggest an additional role for Smad7 as a transcriptional co-repressor [ 50 ] . Thus, Smad7 might interfere directly with Ese-1/Esx gene transcription.
Ese-1/Esx is a member of the Ets transcription factor family and is expressed mainly in epithelial tissue [ 30 ] . Its expression has been detected during mammary gland development and breast tumorigenesis [ 47 48 ] . It is noteworthy that Ese-1/Esx is a potential transcriptional regulator of the TGFβ type II receptor [ 31 ] and overexpression of Ese-1/Esx in non-invasive cells leads to a reduction in cell growth in the presence of TGFβ, presumably because of an increased TGFβ type II receptor level [ 49 ] . It is interesting that TGFβ-dependent downregulation of Ese-1/Esx is not affected by SB-203580.
Furthermore, we show for the first time that, in breast cancer cells, the Ese-1/Esx mRNA is downregulated by TGFβ.
It is remarkable that a constitutively active form of JNK activator MKK and Smad7 are able to cooperatively downregulate TGFβ-responsive promoters [ 53 ] . It is quite possible that a Smad7/JNK synergistic interaction is involved in the TGFβ-dependent downregulation of Ese-1/Esx expression, where JNK alone might mediate the initiation of the TGFβ-induced repression.
