Mutation‐Immune Crosstalk Contextualizes CAF‐Associated ARPC1A Programs and Cisplatin Response in Gastric Cancer
Cisplatin response in gastric cancer is shaped by malignant cell programs, stromal states, and mutation‐immune crosstalk, but the CAF subtypes linked to platinum tolerance and their epithelial effectors remain incompletely defined. We integrated single‐cell RNA sequencing, epithelial CNV‐like inference, fibroblast recl...
