Then, we evaluated the correlations between circ-MAT2B expression and clinicopathological features of GC patients, as shown in Table 1, high circ-MAT2B expression was positively correlated with larger tumor size, lymph node metastasis as well as advanced TNM stage, and patients with high circ-MAT2B had shorter overall and disease-free survival time than those with low circ-MAT2B (Fig. 1b). Here, MAT2B is linked to gastric cancer.
