Article Title: Inhibiting ADAR1‐Mediated Excessive Epigenetic A‐to‐I RNA Editing Improves the Immune Microenvironment and Increases Sensitivity to Immunotherapy in Lung Adenocarcinoma
doi: 10.1002/mco2.70574
Figure Lengend Snippet: Inhibition of ADAR1 enhances sensitivity to immunotherapy in the LUAD mouse model. (A) Schematic diagram of tumor construction from LLC cells, transplantation, and treatment schedule in C57BL/6J mice. (B) Images of tumors derived from sh‐LLC and control‐LLC cells treated with PD‐L1 mAb and isotype control. The groups sh‐LLC and con‐LLC refer to ADAR1‐knockdown LLC cells prepared using shRNA and control LLC cells, respectively. n = 5 mice per group. (C) Tumor growth curves for the four groups. n = 5 mice per group. (D) IHC images of CD8 and PD‐L1 expression in the corresponding groups. (E, F) IHC analysis of CD8 + T‐cell infiltration in the corresponding groups. (G–K) ELISA analysis of IFN‐β, IFN‐γ, CXCL9, CXCL10, and CXCL11 concentrations in the corresponding groups. (L–O) IHC analysis of IFN‐β, CXCL9, CXCL10, and CXCL11 expression in the corresponding groups (* p < 0.05; ** p < 0.01; *** p < 0.001; **** p < 0.0001; t ‐test; error bars represent standard deviation).
