One published gene list [73] contained DE genes (p < 0.05, two-sided moderated t-tests) between suppressive tumor Tregs of CD4-C9-CTLA4 cells (n = 868) vs. other tumor-infiltrating Tregs of CD4-C8-FOXP3 cells (n = 122) as well as DE genes (p < 0.05, two-sided moderated t-tests) between activated tumor Tregs of CD4-C9-CTLA4 (TNFRSF9+, n = 519) vs. non-activated tumor Tregs of CD4-C9-CTLA4 (TNFRSF9−, n = 420). This evidence concerns the gene CTLA4 and neoplasm.
