Peritoneal macrophages from Tgfbr2fl/fl (WT) and LysM-Cre Tgfbr2fl/fl (macrophage TGF-βRII–/–; MφTGF-βRII–/–) mice 3 days after peritoneal thioglycollate administration were used. (A) TGF-βRII levels were markedly lower in TGF-βRII–/– macrophages than in WT macrophages. ***P < 0.001, n = 3 in each group. Data were expressed as mean ± SEM. (B) Macrophages were stimulated with 2 ng/ml recombinant TGF-β for 30 minutes. TGF-βRII deletion led to decreases in TGF-β–stimulated phosphorylation of <t>Smad2</t> and Smad3, an indication of TGF-βRII deficiency. p-Smad3, phospho-Smad3; p-Smad2, phospho-Smad2; FAK, focal adhesion kinase.

Becton Dickinson anti-smad2/3 antibody
Increased cAMP levels inhibit Smad3/4-dependent transcription without alteration of Smad3 phosphorylation and nuclear translocation in response to TGF-β in HDF. A, subconfluent cells were transfected with a Smad-dependent promoter/reporter construct (CAGA)9-luc, together with expression vectors for Smad3 or the corresponding empty vector in a medium supplemented with 1% FCS. 6 h after transfection, forskolin (20 μm) or Bt2cAMP (db-cAMP) (1 mm) was added in the presence (+) or absence of TGF-β (10 ng/ml). Incubations were continued for 20 h after which the reporter gene activity was determined. Results of a representative experiment performed on duplicate samples are shown as relative luciferase activity. B, subconfluent HDF were treated with TGF-β (10 ng/ml) in the presence or absence of forskolin (20 μm) or Bt2 cAMP (1 mm) left untreated. After 30 min, cells were lysed, and samples were processed for Western immunoblotting with specific antibodies for phospho-Smad3 and α-tubulin. C, subconfluent HDF in eight-well tissue chambers were incubated with forskolin (20 μm) or Bt2cAMP (1 mm) together with TGF-β (10 ng/ml). After 30 min, cells were fixed and double-stained with a <t>Smad2/3</t> antibody (red signal) and with 4′,6-diamidino-2-phenylindole (DAPI) to visualize cell nuclei (blue signal) followed by fluorescence microscopy (scale bar, 25 μm).

Figure Lengend Snippet: Increased cAMP levels inhibit Smad3/4-dependent transcription without alteration of Smad3 phosphorylation and nuclear translocation in response to TGF-β in HDF. A, subconfluent cells were transfected with a Smad-dependent promoter/reporter construct (CAGA)9-luc, together with expression vectors for Smad3 or the corresponding empty vector in a medium supplemented with 1% FCS. 6 h after transfection, forskolin (20 μm) or Bt2cAMP (db-cAMP) (1 mm) was added in the presence (+) or absence of TGF-β (10 ng/ml). Incubations were continued for 20 h after which the reporter gene activity was determined. Results of a representative experiment performed on duplicate samples are shown as relative luciferase activity. B, subconfluent HDF were treated with TGF-β (10 ng/ml) in the presence or absence of forskolin (20 μm) or Bt2 cAMP (1 mm) left untreated. After 30 min, cells were lysed, and samples were processed for Western immunoblotting with specific antibodies for phospho-Smad3 and α-tubulin. C, subconfluent HDF in eight-well tissue chambers were incubated with forskolin (20 μm) or Bt2cAMP (1 mm) together with TGF-β (10 ng/ml). After 30 min, cells were fixed and double-stained with a Smad2/3 antibody (red signal) and with 4′,6-diamidino-2-phenylindole (DAPI) to visualize cell nuclei (blue signal) followed by fluorescence microscopy (scale bar, 25 μm).
