From: Clinical and functional significance of tumor/stromal ATR expression in breast cancer patients
Loss of ATR in stromal and tumoral cells is predictive of poor disease-free and overall survival. a Tissue sections cut from formalin-fixed paraffin-embedded breast tumors (different subtypes) were immunostained with anti-ATR antibody. Red arrows indicate stromal fibroblasts, while black arrows indicate cancer cells. (Envision × 60). b, c Kaplan-Meier analysis of overall survival (OS) and disease-free survival (DFS)
