Experimental details: Knockdown of SMAD7 was achieved by transfecting HeLa cells with SMAD7 specific siRNAs (Silencer® select Product # s8412). Western blot analysis (Fig a) was performed using whole cell extracts from the SMAD7 knock down cells (lane 3), non-specific scrambled siRNA transfected cells (lane 2) and un-transfected cells (lane 1). The blots were probed with Anti-SMAD7 Rabbit Polyclonal Antibody (Product # 42-0400, 2µg/mL) and Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate(Product # A27036, 0.25µg/mL ,1:4000 dilution). Densitometric analysis of this western blot is shown in histogram (Fig b). Loss of signal upon siRNA mediated knock down confirms that antibody is specific to SMAD7.

Experimental details: Western blot analysis of SMAD7 was performed by loading 20 µg of Jurkat (lane1) and Hep G2 (lane2) cell lysate using Novex® NuPAGE® 4-12 % Bis-Tris gel (Product # NP0322BOX), XCell SureLock™ Electrophoresis System (Product # EI0002), Novex® Sharp Pre-Stained Protein Standard (LC5800), and iBlot® 2 Dry Blotting System (IB21001). Proteins were transferred to a nitrocellulose membrane and blocked with 5 % skim milk for 1 hour at room temperature. SMAD7 was detected at ~ 45 kDa using SMAD7 Rabbit Polyclonal Antibody (Product # 42-0400) at 1-2 µg/mL in 5 % skim milk at 4°C overnight on a rocking platform. Goat Anti-Rabbit IgG - HRP Secondary Antibody (G21234) at 1:5000 dilution was used and chemiluminescent detection was performed using Pierce™ ECL Western Blotting Substrate (Product # 32106).

Experimental details: Immunofluorescence analysis of SMAD7 was done on 70% confluent log phase HeLa cells. The cells were fixed with 4% paraformaldehyde for 15 minutes, permeabilized with 0.25% Triton™ X-100 for 10 minutes, and blocked with 5% BSA for 1 hour at room temperature. The cells were labeled with SMAD7 Rabbit Polyclonal Antibody (Product # 42-0400) at 1 µg/mL in 1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d is a merged image showing Nuclear localization. Panel e is a no primary antibody control. The images were captured at 60X magnification.

Experimental details: Immunohistochemistry analysis of SMAD7 showing staining in the cytoplasm and nucleus of paraffin-embedded human colon carcinoma (right) compared to a negative control without primary antibody (left). To expose target proteins, antigen retrieval was performed using 10mM sodium citrate (pH 6.0), microwaved for 8-15 min. Following antigen retrieval, tissues were blocked in 3% H2O2-methanol for 15 min at room temperature, washed with ddH2O and PBS, and then probed with a SMAD7 Rabbit Polyclonal Antibody (Product # 42-0400) diluted in 3% BSA-PBS at a dilution of 1:20 overnight at 4°C in a humidified chamber. Tissues were washed extensively in PBST and detection was performed using an HRP-conjugated secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.

Experimental details: Flow cytometry analysis of SMAD7 was done on Jurkat cells treated with TNF alpha (50ng/mL, 20 minutes). Cells were fixed with 70% ethanol for 10 minutes, permeabilized with 0.25% Triton™ X-100 for 20 minutes, and blocked with 5% BSA for 30 minutes at room temperature. Cells were labeled with SMAD7 Rabbit Polyclonal Antibody (420400, red histogram) or with rabbit isotype control (pink histogram) at 3-5 ug/million cells in 2.5% BSA. After incubation at room temperature for 2 hours, the cells were labeled with Alexa Fluor® 488 Goat Anti-Rabbit Secondary Antibody (A11008) at a dilution of 1:400 for 30 minutes at room temperature. The representative 10,000 cells were acquired and analyzed for each sample using an Attune® Acoustic Focusing Cytometer. The purple histogram represents unstained control cells and the green histogram represents no-primary-antibody control.

Experimental details: Fig 4 Cucurbitacin I blocks the TGF-beta/Smad signaling pathway in hypertrophic cardiomyocytes. Cell extracts (50 mug) were used for Western blot analysis of TGF-beta and Smad (Smad2, 3, and 7) protein expression levels. The expression levels of TGF-beta, Smad2, 3, and 7, and the phosphorylated forms of Smad2 and 3 (p-Smad2 and p-Smad3) were estimated by measuring band densities with NIH Image J software. GAPDH was used as a loading control. And Western blot analysis was performed in triplicate with three independent samples. Data are expressed as fold changes +- S.D. vs. control group. Significance was measured via a two-way ANOVA. * P < 0.05. Cont, control; Cu I, Cucurbitacin I.
