[Retracted] TGF-β1 Induces Interlukin-11 Expression and Pro-Fibrotic Effect by DNA Demethylation in Subconjunctival Fibroblasts

Figure 4

TGF-β1 induces changes in the DNMT activity and expression in the HTFs. (a) Upon serum starvation for 12 h, the HTFs were treated with 10 ng/mL TGF-β1 for 0, 6, 12, and 24 h. The global DNMT activity was analyzed by a DNMT activity assay kit. The DNMT activity in the TGF-β1-treated HTFs was much lower than that in the control (n = 3). (b) Expression changes in the DNMTs over different time periods assessed by RT-qPCR. (c) Typical pictures of western blots of DNMTs at 0, 6, 12, and 24 h after TGF-β1 treatment of the HTFs. (d) DNMT1, DNMT3a, and DNMT3b protein levels in the HTFs after TGF-β1 treatment. Data were average value and SD from three independent trials, triplicate samples for each. , , vs. 0 h by one-way ANOVA and the Fisher test.
