Targeting GEM Reprograms Macrophages and Overcomes Immunotherapy Resistance in Esophageal Squamous Cell Carcinoma.
Esophageal squamous cell carcinoma (ESCC) exhibits heterogeneous responses to immune checkpoint blockade, highlighting the need to define tumor-intrinsic mechanisms driving resistance to PD-L1 inhibition. Here, we identified GTP-binding protein overexpressed in skeletal muscle (GEM) as a tumor cell-intrinsic regulator...
