To investigate the potential role of Dock6 in GC, we analyzed the mRNA expression levels of Dock6 in 30 pairs of GC tissues and adjacent nontumor tissues, and real-time PCR results showed that Dock6 mRNA expression was significantly higher in GC tissues than in nontumor tissues (Fig. 1a, P< 0.01). The gene discussed is DOCK6; the disease is gastric cancer.
