AXIN2 and colorectal cancer: We also verified the expression of Axin2 in colorectal cancer tissue were higher than adjacent tissue (Fig. 5D), and Pearson correlation analysis showed a nagetive correlation between Axin2 and miR-195-5p expression level (Fig. 5E), and a positive correlation between Axin2 and circ_0038718 expression level, respectively (Fig. 5F).
