As shown in Figure 2(a), the mRNAs of Hlx, T-bet, Runx3, and IFN-γ were significantly decreased in peripheral blood mononuclear cells from patients with gastric cancer compared with healthy controls (P < 0.05, P < 0.05, P < 0.01, and P < 0.05). The gene discussed is RUNX3; the disease is gastric cancer.
