Localization and translocation of RhoA protein in the human gastric cancer cell line SGC-7901

Figure 8 LPA-induced RhoA translocation from cytosol towards membrane and nucleus in SGC-7901 cells. SGC-7901 cells were treated with or without LPA (1 &mgr;mol/L, 15 min). Control or LPA -treated cells were lysed and the membrane (A), cytosolic (C), and nuclear (B) fractions were obtained. Expressions of RhoA and GAPDH proteins in each fraction were detected by Western blotting, and the representative band images were shown in the left panels. Densitometric analysis of the bands was shown in the right panels. Each bar represents mean ± SE obtained from five independent experiments. ^aP < 0.05.
