This research paper presents a multiomic and spatial atlas of lung adenocarcinoma (LUAD) to determine how TP53 mutations reshape the cellular landscape of tumors. The study reveals that malignant cells with these mutations lose their alveolar identity and transition into a highly plastic, entropic state characterized by increased proliferation and hypoxia. Beyond the cancer cells, the researchers identified a distinct multicellular ecosystem where specific fibroblasts and macrophages coordinate to promote a prometastatic environment. Evidence also shows that these mutated tumors suffer from…
