A significant and positive correlation of gene expression was found between UNG and APOBEC3B in both tumor subtypes (LAS: R=0.33 and P=8.8e-04; HAS: R=0.45 and P=1.5e-05), but not between UNG and APOBEC3A (LAS: R=-0.094 and P=0.36; HAS: R=0.046 and P=0.67; Fig. 2b). Here, APOBEC3B is linked to neoplasm.
