Figure 2. SGK3 promotes cell migration and invasive potential.

A. Depletion of SGK3 in SMMC-7721 and Huh-7 cells. Cells were transfected with siRNAs against AGK3 and controls, and then subjected to Western blotting with an anti-SGK3 antibody. β-actin was used as loading control. B. Overexpression of SGK3 in SMMC-7721 and Huh-7 cells. Cells were transfected with empty vector or a vector expressing SGK3, and then subjected to Western blot analysis with an anti-SGK3 antibody. β-actin was used as loading control. C. Control and SGK3-depleted SMMC-7721 and Huh-7 cells were subjected to a transwell Matrigel invasion assays D. Empty vector and SGK3-overexpressing SMMC-7721 and Huh-7 cells were subjected to a transwell Matrigel invasion assays E. Control and SGK3-depleted SMMC-7721 and Huh-7 cells were subjected to a transwell migration assays F. Empty vector and SGK3-overexpressing SMMC-7721 and Huh-7 cells were subjected to transwell migration assays. All experiments were performed in triplicate, and the results are shown as the mean ± standard deviation.
