Tangeretin Inhibition of High-Glucose-Induced IL-1β, IL-6, TGF-β1, and VEGF Expression in Human RPE Cells

Figure 1

Effect of tangeretin on human RPE cell viability. The cells were incubated with different concentrations of tangeretin (0, 5, 10, 20, and 30 μM) for 24 h. The MTT assay was then performed to measure cell viability of human RPE cells. vs. control group (0 μM).
