Figure Lengend Snippet: Recombinant Meprin α Inhibits Activation of NR8383 Macrophages Induced by SiO 2 (A) Protein expression of meprin α, MCP-1, TGF-β1, TGF-βR I, TGF-βR II, and p-Smad2/3 was measured in NR8383 cells treated with 10, 25, and 50 μg/cm 2 silica. * Compared with control group, p < 0.05. (B) Expression of pro-COL I, MCP-1, TGF-β1, TGF-βR I, TGF-βR II, and p-Smad2/3 was measured in NR8383 cells treated with SiO 2 , SiO 2 plus meprin α, and SiO 2 plus actinonin. * Compared with control group, p < 0.05; # Compared with SiO 2 group, p < 0.05. Data are presented as the mean ± SD. n = 3 per group.
Article Snippet: Protein samples (10 μg) were solubilized in 5× sample buffer (AS0001-5, Seracare, USA), heated at 95°C for 10 min, centrifuged at 3,000 × g for 1 min, loaded on a 12% Tris-HCl-SDS-polyacrylamide gel, and separated for 1 h at 120 V. Proteins were transferred to a polyvinylidene fluoride (PVDF) membrane (31337600, Roche Diagnostics, Germany) and then blocked with 5% BSA for 1 h at room temperature, followed by incubation overnight at 4°C with a specific primary antibody against meprin α, COL I (ab34710, Abcam), α-SMA, MCP-1 (DF7577, Affinity, USA), TGF-β1 (ARG56894, Arigo Biolaboratories, Taiwan, China), TGF-βR I (A16983, ABclonal, Wuhan, China), TGF-βR II (ARG59501, Arigo), p-Smad2/3 (8828s, Cell Signaling Technology, MA, USA), or Smad2/3 (5678, Cell Signaling Technology), followed by incubation with goat anti-rabbit or anti-mouse secondary antibodies (074-1506/074-1806, Kirkegaard & Perry Laboratories, USA) at a dilution of 1:5,000 in blocking buffer.
