Recently, DNA DSB repair has been implicated in regulating the expression of PD‐L1 in cancer cells (Sato et al., 2017), and the effect of ATR inhibition on PD‐L1 expression, and consequently on immune surveillance of tumor cells, has been investigated (Sun et al., 2018; Vendetti et al., 2018). This evidence concerns the gene CD274 and neoplasm.
