ATG downregulates the expression of TGF-β1 in BLM-induced skin fibrosis model mice. (A) Representative fluorescence images of skin sections stained against TGF-β1 (green). Nuclei were counterstained with DAPI (blue). Scale bar, 30 µm; magnification, ×200. (B) TGF-β1 mRNA expression levels were measured via reverse transcription-quantitative PCR. (C) TGF-β1 protein expression levels were measured via western blotting. **P<0.01. ATG, arctigenin; BLM, bleomycin; Con, control.
