The human alpha11 integrin promoter drives fibroblast-restricted expression in vivo and is regulated by TGF-beta1 in a Smad- and Sp1-dependent manner.
Transfection and expression of the inhibitory Smad7 in the cells attenuated the TGF-beta1-dependent alpha11 induction both at the RNA and the protein level. Mutation and deletion analyses identified a Smad-binding element, SBE2 (nt -182/-176), as an important Smad3-binding site in this part of the promoter. Further analyses suggested that the Sp1-binding site SBS1 (nt -140/-134) takes part in the responsiveness to TGF-beta1 in a Smad2-dependent manner.
