ATD blocks FMT
(A) Picrosirius red staining of HFL1 cells was treated with various concentrations of ATD (10, 100, and 1,000 nM) in the presence or absence of TGF-β1 (5 ng/mL) stimulation for 48 h. Scale bars, 400 μm. (B–D) Quantitative RT-PCR assays were performed to determine mRNA expression of genes related to extracellular matrix (FN1 and COL1A1) and fibrotic marker (ACTA2) in HFL1 cells (n = 6). (E) The expression levels of fibrosis biomarkers. Quantification of (F) fibronectin, (G) collagen I, (H) collagen III, and (I) α-SMA expression using ImageJ. Each data point was repeated 6 times (n = 6). PFD-treated cells were the positive control group. The data are presented as the mean ± SEM. #p < 0.05, ##p < 0.01, ###p < 0.001 compared with the control group; ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001 compared with the TGF-β1 group. ns, no statistical difference.
