Using the paraffin slides of gastric cancer, no significant changes were noted in the ratio of Foxp3+ Tregs in the tumor when Gan mice were fed a high-fat diet with GO-Y022 (number of Tregs in the tumor: control mice = 2.34 ± 2.65/mm2, GO-Y022-treated mice = 2.20 ± 2.47/mm2, p-value = 0.9487) (Figures 5A, B). This evidence concerns the gene FOXP3 and gastric cancer.
