GPR174 and neoplasm: Meanwhile, survival analysis showed that LUAD patients with high GPR65 expression had longer OS than those with low LUAD expression (Figure 3B; p = 0.003), while both GPR174 and MS4A1 were highly expressed in tumor samples (Figures 3C, E), and LUAD patients with high expression of GPR174 and MS4A1 had a better survival prognosis than the low expression group (Figures 3D, F; p = 0.002, p < 0.001).
