Expression of Treg cells is elevated in gastric cancer. (A) Relative FOXP3 mRNA expression in 32 pairs of cancerous and noncancerous tissues from gastric cancer patients in TCGA database. (B-C) Flow cytometry assay demonstrated elevated expression of Treg cells in fresh samples from 20 gastric cancer patients. (D-E) Immunohistochemistry staining showed that expression of Treg cells was significantly increased in gastric cancer tissues compared with that in normal tissues. Values are mean ± s.d., ***P < 0.001 (Student’s t-test)
