TGF-β neutralizing antibody does not inhibit Smad1,5,8 phosphorylation and the VEGF upregulation induced by Dkk-3. (A) Western blot analysis of phosphoSmad1,5,8 in cells exposed for 60 min to hrDkk-3 either in the presence or in the absence of neutralizing TGF-β antibody. (B) Corresponding densitometric analysis. Values are means ± SD. (C) Western blot analysis of VEGF in cells exposed for 12 h to hrDkk-3 either in the presence or in the absence of neutralizing TGF-β antibody. (D) Corresponding densitometric analysis. Values are means ± SD.
