Emodin repressed EMT by targeting ILK in A2780 and SK-OV-3 cells. (a, c) A2780 and SK-OV-3 cells were transfected with siRNA-ILK and treated with or without emodin 20 μM for 48 hours. Protein levels of ILK, p-GSK-3β, GSK-3β, β-catenin, Slug, E-cadherin, and N-cadherin were shown. (b, d) Quantitative analyses of factors in SK-OV-3 cells shown in (a) and (c). ∗
