Overexpression of nt 91–150 circNOLC1 substitution mutation remarkably reduced CRC cell proliferation and migration abilities compared with full‐length circNOLC1 (Figure S4G–J, Supporting Information), suggesting that nt 91 to 150 of circNOLC1 are required for the interaction of circNOLC1 with AZGP1. The gene discussed is AZGP1; the disease is colorectal carcinoma.
