1190-Inflammatory Cytokines and Induced Cancer Dependencies

The article details a large-scale study using CRISPR genetic screening to map how cancer cells adapt to inflammatory cytokines like interferon and tumor necrosis factor. By testing eight different mouse cancer models, researchers identified specific genetic vulnerabilities that appear only when tumors are exposed to the inflammatory stress of the immune system. A key discovery involves the FITM2 gene and the GPI transamidase complex, which normally help cancer cells survive under these conditions. The study demonstrates that removing these specific genes significantly improves the effectiveness of immune checkpoint blockade therapies in living subjects. Ultimately, these findings offer a new strategy for making tumors more susceptible to the body’s natural defenses by targeting their intrinsic stress response pathways.References:Cheruiyot CK, Kim SY, Dubrot J, Lane-Reticker SK, Miranda A, Kammula AV, Perera JJ, Du PP, Chuong CL, Fetterman RA, Knudsen NH, Jiang A, Suermondt JSMT, Pass LF, Fu C, Wu MJ, Shi L, Anderson S, Muscato AJ, Avila OI, Kohnle IC, Kessler EA, Pope HW, Noel SG, Olander KE, Chung J, Colvin KJ, Bardeesy N, Yates KB, Manguso RT.
