Project description:Maintenance of immunological homeostasis between tolerance and autoimmunity is essential for the prevention of human diseases ranging from autoimmune disease to cancer. Accumulating evidence suggests that p53 can mitigate phagocytosis-induced adjuvanticity thereby promoting immunological tolerance following programmed cell death. Here we identify Inhibitor of Apoptosis Stimulating p53 Protein (iASPP), a negative regulator of p53 transcriptional activity, as a regulator of immunological tolerance. iASPP-deficiency promoted lung adenocarcinoma and pancreatic cancer tumorigenesis, while iASPP-deficient mice were less susceptible to autoimmune disease. Immune responses to iASPP-deficient tumors exhibited hallmarks of immunosuppression, including activated regulatory T cells and exhausted CD8+ T cells. Interestingly, iASPP-deficient tumor cells and tumor-infiltrating myeloid cells, CD4+, and γδ T cells expressed elevated levels of PD-1H, a recently identified transcriptional target of p53 that promotes tolerogenic phagocytosis. Identification of an iASPP/p53 axis of immune homeostasis provides a therapeutic opportunity for both autoimmune disease and cancer.

Project description:We performed p53 ChIP-seq analysis of Nutlin-treated HCT116 cells to identify high-confident p53 regulated targets. And we performed ChIP-seq using an anti-p53 antibody in HCT116 cells treated with control or iASPP RNAi to identify iASPP regulated p53 targets.

Project description:To investigate the transcriptomic effects of iASPP deletion or p53 mutation in the KRASG12D background Pdx1-Cre was used to delete iASPP in oncogenic KRASG12D expressing (KC) background to generate KC;iASPPΔ8/Δ8 mice. KC and KC;iASPPΔ8/Δ8 mice were then crossed with mice containing a p53R172H allele (equivalent to human p53 hotspot mutation R175H) to generate KPC and KPC;iASPPΔ8/Δ8 cohorts. Primary cell cultures were then derived from pancreatic ductal adenocarcinoma tissue for RNA-seq.
