Figure 5. SFN suppresses expression of fibronectin upregulated by TGF-β2 in ARPE-19 cells.

A: Cells were exposed to various SFN concentrations and were serum starved for 24h prior to incubation in the absence of presence of TGF-β2 for 72h. Fibronectin levels were detected in the cell lysates using Western blotting; B: Qualitative analysis of bands. ^aP<0.05 vs Control group; ^bP<0.05 vs TGF-β2. All experiments were independently repeated three times.
