G2E3 and inflammatory bowel disease: The expressions of G2E3 in blood samples of patients with IBD were significantly lower than that of the control (P = 0.0036; Fig. 3D), and positive correlations between G2E3 expression and SCFD1 expression were observed in both patients with IBD (Spearman ρ [95% CI] = 0.31 [0.20-0.40], P = 1.92×10-8;Fig. 3D) and control subjects (Spearman ρ [95% CI] = 0.42 [0.31-0.51], P = 1.42×10-12; Fig. 3D).
