COL1A2 and gastric cancer: Among them, high expressions of COL1A1 (P.value: 8.9E-5), COL1A2 (P.value: 0.0015), TIMP1 (P.value: 1.5E-10), THBS2 (P.value: 1.2E-6), COL4A1 (P.value: 5.5E-7), MUC6 (P.value: 0.0151), and BGN (P.value: 1.5E-10) were significantly correlated with poor overall survival probability for GC patients (Fig. 8).
