    Article Snippet: Various TGF-β1 concentrations (0.1–10 ng/mL) were administered for 2 days after the cells stabilized for 24 h to construct the fibrosis model. For analysis, miRNA mimics and inhibitors were transfected into TGF-β1-treated and untreated groups for 48 h. A THBS1 inhibitor LSKL (MedChemExpress USA, Middlesex, NJ, USA) was simultaneously added at 20 μM in the TGF-β1-treated and untreated groups and cultured for 48 h.
