Figure 7.

Effect of SCE on IL-1β-induced phosphorylation of NF-κB in ARPE-19 cells. ARPE-19 cells were treated with 1–100 µg/mL SCE in 0.5% DMSO for 1 h before adding IL-1β for 24 h. Protein expression of phosphorylated NF-κB p65 and total NF-κB p65 was determined using immunoblotting. Equal loading of protein in each well was normalized to the total form of NF-κB p65. Data are presented as mean ± SD (n = 3). The different superscripts (a–e) indicate significant differences among groups at p < 0.05.
