Table 1 The expression level of circNRIP1 is significantly correlated with the GC tumour size and lymphatic invasion, and the expression level of miR-149-5p is negatively correlated with the GC tumour size

From: Circular RNA circNRIP1 acts as a microRNA-149-5p sponge to promote gastric cancer progression via the AKT1/mTOR pathway
