UQCRC2 and gastric cancer: The downregulation of UQCRC2 was indicative of reduced overall survival (OS; hazard ratio [HR]=1.13, 95%CI [1.09‐1.18], P < 0.01) and disease-free survival (DFS; HR = 1.89, 95%CI [1.54‐2.30], P < 0.01) of patients with GC relative to the upregulation of UQCRC2 (Fig. 1E-F), suggesting the potential of using UQCRC2 to predict GC prognosis.
