To address the clinical significance of RhoGDI2 and FLNA expression in gastric cancer patients, we analyzed public microarray data sets (GSE54129, GSE26901 and GSE26942), and found that expression of RhoGDI2 and FLNA was increased in gastric cancer tissues compared to normal tissues (Figure 5A,B), and increased in advanced-stage gastric cancer tissues (tumor stages III and IV) more than in early-stage gastric cancer tissues (tumor stages I and II) (Figure 5C,D). Here, FLNA is linked to gastric cancer.
