Recombinant human tgf β1 240 b

Primary RMCs were obtained by explant culture of renal glomeruli isolated from Sprague-Dawley male rats (160–180 g) as described [23 (link)] with the allowance of the Ethics Committee on the Care and Use of Laboratory Animals of the Second Hospital of Jilin University (Changchun, China). RMCs were maintained in RPMI 1640 medium. The subsequent experiments were performed with RMCs from passages 6–10. RMCs were serum depleted in 0.2% BSA medium for 24 h prior to stimulation. RMCs were treated with 10 ng/mL Recombinant Human TGF-β1 (240-B, R&D systems, Minneapolis, MN) as indicated time, while control groups were treated with the vehicle.

Reagents were analytical grade and obtained from Sigma-Aldrich (UK) unless otherwise stated. Recombinant human FGF-2 (#100-18B) was from PeproTech (UK), recombinant human TGFβ1 (#240-B) from R&D Systems (UK), BGJ398 from Santa Cruz (USA), Gö6976 from Cell Signaling Technology (USA), and SB431542 from Sigma-Aldrich (UK). An equivalent volume of vehicle was used a control for each compound in experiments: 0.1% (w/v) bovine serum albumin (BSA) in 5 mM TRIS for FGF-2, dimethyl sulfoxide (DMSO) for BGJ398, Gö6976 and SB431542, and 0.1% (w/v) BSA in 4 mM HCl for TGFβ1. Antibodies to phosphorylated Smad2 (#3108), Smad2 (#5339), protein kinase Cα (PKCα, #2056), phosphorylated Akt (#4060), Akt (#9272), phosphorylated Erk1/2 (#4377), and Erk1/2 (#4695) were from Cell Signaling Technology (USA). Antibodies to syndecan-4 were from Santa Cruz (sc-12766) or Biovision, USA (#3644). Antibodies to FGF-2 (sc-79) were from Santa Cruz (USA), phosphorylated PKCα (07-790) from Merck Millipore (Germany), and β-actin (#A1978) from Sigma-Aldrich (UK).

Recombinant human TGF-β1 (240-B) was purchased from R&D Systems (Minneapolis, MN). Mouse anti-FOXK1, Snail, Vimentin, E-Cadherin, β-catenin and GAPDH were purchased from Santa Cruz Biotechnology (Santa Cruz, CA). FHC, HT-29, SW480, Lovo, SW1116, SW620, Colo205 and DLD1, cells were grown in RPMI 1640 containing 10% fetal bovine serum (Life Technologies, Monza, Italy), 1% glutamine (Life Technologies) and 1% penicillin/treptomycin (Life Technologies) in a humidified incubator at 37°C with an atmosphere of 5% CO₂.

The antibodies used in this study are listed in Table 1 and Table 2. Recombinant human TGF-β1 (#240-B) and recombinant human HSP70 (eHSP70; #AP-100) were purchased from R&D Systems (Abingdon, UK). The GR inhibitor (AL082D06) was purchased from Selleckchem (#S6608, Houston, TX, USA). The TLR2 inhibitor (C29) was purchased from MedChem Express (#HY-100461, Monmouth Junction, NJ, USA). The TLR4 inhibitor (LPS-RS) was purchased from InvivoGen (#tlrl-rslps, San Diego, CA, USA).

Recombinant human IL2 was obtained through the AIDS Research and Reference Reagent Program, Division of AIDS, NIAID, NIH from Dr. Maurice Gately, Hoffmann - La Roche Inc. LPS and Concanavalin A (ConA) were purchased from Sigma-Aldrich (St. Louis, MO). Anti-mouse IgG coated magnetic Dynabeads® M-450 were purchased from Dynal (Great Neck, NY). Streptavidin–PerCP was purchased from BD Biosciences PharMingen (San Diego, CA). Anti-TGFβ1 (MAB240) was purchased from R&D Systems (Minneapolis, MN) and conjugated to allophycocyanin (APC) or left unconjugated for blocking studies; PE-conjugated anti-TGFβ-RII (FAB241P), neutralizing anti-TGFβRII (AF-241-NA), and recombinant human TGFβ1 (240-B) were also purchased from R&D Systems. Mouse anti-feline CD25 (mAb 9 F23) was kindly provided by K. Ohno (University of Tokyo, Tokyo, Japan). Anti-CD21 was purchased from Serotec (Raleigh, NC). Mouse anti-feline CD4 (mAb 30A) and CD8 (mAb 3.357) were developed in our laboratory [43 (link)]. PE conjugated rat anti-mouse FoxP3 (FJK-16 s) was purchased from eBioscience (San Diego, CA).
