A qRT-PCR revealed the influence of silenced SMO on MIRLET7BHG expression. B Luciferase reporter assay disclosed the luciferase activity of MIRLET7BHG promoter when SMO was subjected to downregulation. C Western blot tested hedgehog pathway-associated proteins (SMO and Gli1) in indicated groups. D qRT-PCR verified the overexpression efficiency of Gli1 and the influence of upregulated Gli1 on MIRLET7BHG expression. E qRT-PCR tested the knockdown efficiency of Gli1 and the influence of downregulated Gli1 on MIRLET7BHG expression. F Luciferase reporter assay analyzed the luciferase activity of MIRLET7BHG promoter in activated HSCs with or without the upregulation of Gli1. G DNA motif of Gli1 and two binding sites of Gli1 on MIRLET7BHG promoter. H ChIP assay revealed the enrichment of MIRLET7BHG promoter in anti-Gli1 group relative to control anti-IgG group. I Luciferase reporter assay determined the impact of Gli1 overexpression on the luciferase activity of reporters with indicated MIRLET7BHG promoter (wild-type, site 1-mutated type, site two-mutated type, or site 1/2-mutated type). *P < 0.05, **P < 0.01, “n.s” represents no significance.
