Article Title: Adenovirus-mediated knockdown of activin A receptor type 2A attenuates immune-induced hepatic fibrosis in mice and inhibits interleukin-17-induced activation of primary hepatic stellate cells
Figure Lengend Snippet: Ad-ACVR2A shRNA suppresses IL-17-induced activation of primary mHSCs in vitro . The primary mHSCs were infected with Ad-ACVR2A shRNA or Ad-NC shRNA for 24 h, and were then stimulated with recombinant IL-17A or IL-17F for an additional 48 h. (A) Knockdown efficiency of Ad-ACVR2A shRNA was confirmed in normal mHSCs by western blot analysis. (B and D) Production of collagens I and VI in cell supernatants were determined by ELISA kits. (C and E) Protein expression levels of α-SMA, p-Smad2 and total Smad2 were determined by western blot analysis. Data are expressed as the means ± standard deviation (n=3/group). α-SMA, α-smooth muscle actin; ACVR2A, activin A receptor type 2A; IL-17, interleukin-17; mHSCs, mouse hepatic stellate cells; NC, negative control; p, phosphorylated; shRNA, short hairpin RNA.
Article Snippet: Recombinant murine IL-17A and IL-17F (PeproTech, Inc., Rocky Hill, NJ, USA) at 10, 30 or 100 ng/ml were used to stimulate mHSCs for 1, 3, 6, 12, 24 or 48 h. For some experiments, the mHSCs were infected with Ad-ACVR2A shRNA or Ad-NC shRNA (multiplicity of infection, both 50) for 24 h, and were then stimulated with recombinant IL-17A (30 ng/ml) or IL-17F (30 ng/ml) for additional 48 h.
