We then explored DLG3 expression at the single-cell level, with the BRCA_EMTAB8107 cohort showing high expression of DLG3 predominantly in malignant cells, fibroblasts, and CD8Tex (Figures 11C, D), and multiple BC single-cell cohorts of TISCH2 further showing that DLG3 was expressed predominantly with subpopulations of malignant cells and cells such as Tprolif (Supplementary Figure S4E). The gene discussed is DLG3; the disease is breast cancer.
