Transformed KC;iASPPΔ8/Δ8 pancreatic cells expressed higher amounts of PD-1H and PD-L1 in vivo (Fig. 6A), suggesting that these co-inhibitory receptors might be some of the tumor-intrinsic factors responsible for mitigating anti-tumor immunity following iASPP loss. Here, PPP1R13L is linked to neoplasm.
