Project description:The genetic circuits that allow cancer cells to evade destruction by the host immune system remain poorly understood. To identify a phenotypically robust core set of genes and pathways that facilitate cancer cell-intrinsic evasion to cytotoxic T lymphocyte (CTL)-mediated killing, we performed genome-wide CRISPR screens across a panel of genetically diverse cancer models cultured in the presence of CTLs. We uncovered a core set of 182 genes whose individual perturbation leads to either cancer cell sensitivity or resistance to CTL toxicity. Systematic exploration of our dataset using genetic co-similarity reveals the hierarchical and coordinated nature by which genes and pathways act to orchestrate intrinsic CTL evasion, with discrete functional modules controlling the interferon response and tumor necrosis factor alpha (TNFa)-induced cytotoxicity emerging as dominant sub-phenotypes. Our data establish a central role for previously identified negative regulators of the Type II interferon response (e.g. Ptpn2, Socs1, Adar1) in mediating intrinsic CTL evasion and demonstrate a requirement for the lipid droplet related gene Fitm2 for maintaining cell fitness upon exposure to interferon gamma (IFNg). Additionally, we identify the autophagy pathway as a conserved mediator of cancer intrinsic CTL evasion, required to resist cytokine-mediated cytotoxicity caused by IFNg and TNFa. By mapping cytokine- and CTL-based genetic interactions, as well as in vivo CRISPR screens, we illuminate the pleiotropic nature by which autophagy acts to orchestrate intrinsic CTL evasion and highlight the importance of our observed effects within the tumor microenvironment. Collectively, our data expands our appreciation of the genetic circuits that contribute to cancer intrinsic immune evasion, highlighting the importance of leveraging systematic functional genomics approaches for furthering our understanding of this biology.

Project description:The genetic circuits that allow cancer cells to evade destruction by the host immune system remain poorly understood1-3. Here, to identify a phenotypically robust core set of genes and pathways that enable cancer cells to evade killing mediated by cytotoxic T lymphocytes (CTLs), we performed genome-wide CRISPR screens across a panel of genetically diverse mouse cancer cell lines that were cultured in the presence of CTLs. We identify a core set of 182 genes across these mouse cancer models, the individual perturbation of which increases either the sensitivity or the resistance of cancer cells to CTL-mediated toxicity. Systematic exploration of our dataset using genetic co-similarity reveals the hierarchical and coordinated manner in which genes and pathways act in cancer cells to orchestrate their evasion of CTLs, and shows that discrete functional modules that control the interferon response and tumour necrosis factor (TNF)-induced cytotoxicity are dominant sub-phenotypes. Our data establish a central role for genes that were previously identified as negative regulators of the type-II interferon response (for example, Ptpn2, Socs1 and Adar1) in mediating CTL evasion, and show that the lipid-droplet-related gene Fitm2 is required for maintaining cell fitness after exposure to interferon-γ (IFNγ). In addition, we identify the autophagy pathway as a conserved mediator of the evasion of CTLs by cancer cells, and show that this pathway is required to resist cytotoxicity induced by the cytokines IFNγ and TNF. Through the mapping of cytokine- and CTL-based genetic interactions, together with in vivo CRISPR screens, we show how the pleiotropic effects of autophagy control cancer-cell-intrinsic evasion of killing by CTLs and we highlight the importance of these effects within the tumour microenvironment. Collectively, these data expand our knowledge of the genetic circuits that are involved in the evasion of the immune system by cancer cells, and highlight genetic interactions that contribute to phenotypes associated with escape from killing by CTLs.
