Reportedly, increased expression of METTL7A was observed in methotrexate‐resistant cancer cell lines and choriocarcinoma tissues.[26] In contrast, the under‐editing of chr1:1419898 in the intronic region of ATAD3B was a risk factor for patient survival in bladder urothelial carcinoma (BLCA) (Figure 3D). The gene discussed is ATAD3B; the disease is cancer.
