FIGURE 4.
Effect of astilbin on HG-induced the expression of TGF-β1, CTGF, MMP-2, and MMP-9. HBZY-1 cells were treated with 10 and 20 μg/ml of astilbin under HG condition for 24 h. The mRNA levels of TGF-β1 (A) and CTGF (B) in HBZY-1 cells were detected by qRT-PCR. The secretion levels of TGF-β1 (C) and CTGF (D) in cell supernatant were detected by ELISA. (E) The expression levels of MMP-2 and MMP-9 were determined by western blot. #P < 0.05 vs. Con (control group). ∗P < 0.05 vs. HG-stimulated group. Statistical significance was determined by one-way ANOVA.
