Integrin α9 Suppresses Hepatocellular Carcinoma Metastasis by Rho GTPase Signaling

Figure 5

ITGA9 affects focal adhesions and Rho GTPase activity. (a and b) Immunofluorescence staining of paxillin (red) and vinculin (red). F-Actin was stained by FITC phalloidin (green), and the cell nuclei were stained by DAPI (blue). Scale bars, 10 μm. (c) Pull-down assays of the activities of RhoA, Cdc42, and Rac1 in ITGA9-overexpressed or control HCC cells. (d) FAK and Src phosphorylation of ITGA9-overexpressed versus control HCC cells. Tubulin was used as an internal control. Values are means ± SEM. ns: no significance. and .
