The POLQ expression was increased in primary ATM-deficient MCL cells, which was further confirmed by a publicly available MCL gene expression dataset that showed significantly increased POLQ expression with no change to CCND1 expression levels in ATM-mutated MCL compared with ATM-WT MCL (Supplemental Figure 4, F–H) (56). This evidence concerns the gene CCND1 and mantle cell lymphoma.
